Metal Workers with Corneal Injuries and Abuse of Topical Drugs

AIM: We evaluated metal workers injured with corneal foreign bodies (FB) in terms of health insurance, use of protective eyeglasses, and unprescribed drug use. Materials and Methods: Seventy metal workers who were injured with corneal FB were enrolled in the study. We recorded the gender, age, duration of work, use of protective eyeglasses, and health insurance status data of metal workers. In cases of FB existence, the number of FBs and unprescribed drug use were investigated. We examined the presence of corneal scars that could lead to visual impairment. Results: The mean duration of work was 11.8±10.8 years. Although 29 workers (41.5%) had corneal scars, only three workers (4.3%) had visual impairment due to scars. Also, 29 workers (41.5%) did not report the use of protective glasses; however, 22 (31.4%) workers reported their occasional use and 19 (27.1%) workers reported their routine use. Eighteen workers (25.7%) remarked on topical drug use from time to time. Ten of the 18 patients (55.6%) were using topical Tetrahydrozoline HCL, whereas five (27.8%) were using the topical anesthetic drug 0.5% Proparacaine HCl. Conclusion: Occupational protective measures are important for metal workers who are at a high risk of eye injuries. Workers must be educated on the prevention and treatment of occupational ophtalmological hazards and be warned about the side effects of taking unprescribed drugs. Language: en

Presbyopic correction coverage and barriers to the use of near vision spectacles in rural Abuja, Nigeria

Purpose: To determine the presbyopia correction coverage and the barriers to the use of near vision spectacles in rural Gwagwalada, Nigeria. Materials and Methods: Eligible subjects were refracted, with their distance correction in place, near vision was tested and corrected using World Health Organization guidelines. A pretested near vision-related questionnaire was administered to collect information on spectacle use, barriers to the use of near vision spectacles and willingness to pay for replacement spectacles. Presbyopic correction coverage, met, and unmet presbyopic spectacle needs were calculated. Results: The presbyopic correction coverage for the sample was 21%, the met need was 11.2%, and the unmet presbyopic need was 42.1%. Presbyopic correction coverage was significantly higher for males, skilled workers, and those with at least secondary education. Barriers to obtaining near vision spectacles included cost (51.3%) and spectacles not being a priority (19.7%). Skilled workers and those with at least secondary education were willing to pay up to one thousand naira ($5) for replacement spectacles. Conclusion: Presbyopic correction coverage is low with a large unmet need. A community-based approach to the provision of spectacles that are new, of good quality, accessible, and affordable is needed.

Prevalence, progression and associations of corrected refractive errors: a cross-sectional study among students of a Medical College of Odisha, India

Background: WHO estimates that Refractive errors are a major cause of blindness in the world leading to 42% cases of visual impairment. Refractive errors are a significant issue among young adults; this study was conducted to find out the prevalence, progression and associations of refractive errors in medical students. Methods: This was a cross-sectional study conducted among all the students of MKCG Medical College, Berhampur, Odisha, India. Results: Out of the 506 subjects analysed, 47.4% used spectacles and 2.2% used contact lens. 48.8% of spectacle users and 81.8% of contact lens users were females and the rest males. The mean age of the sample was 22.52 years (SD=1.90). The mean age at which refractive error was diagnosed is 16.47 (SD=3.42) and the duration of corrected refractive errors was 5.90 years (SD=3.90). The most common refractive error prevalent was Myopia (54.5%) followed by combined myopia and astigmatism (31.3%), hypermetropia (8.6%) and astigmatism (5.6%). The corrected refractive error ranged from 0.25 to -12.5 D for Myopics and 0.25 to -2.5 D for Hypermetropia with a median correction of -1.75 D spherical, 0.00 D cylindrical in the right eye and the left eye alike. 73.3% of the subjects reported an increase in refractive errors since diagnosis. There was a significant increase in refractive error in myopia as compared to hypermetropia (χ2=5.20, p=0.023) and no difference between males and females (p=0.91). 26.7% respondents reported selective use of spectacles and 62.5% used bright light for reading purposes. Their most preferred activity during leisure time was mobile phone use (43.8%) followed by laptop/pc use (16.3%). 90% had at least 1 ophthalmological check up in the last 12 months. Significant difference was found among those with and without refractive errors in their Height (p=0.026), time spent reading per day (p=0.001). Significant positive correlation was reported between duration of spectacle use and the increase in dioptre power (r=0.32, p<0.01 for spherical and r= 0.24, p<0.01 for cylindrical). No significant difference was found among the same regarding patterns of TV / PC/ Mobile phone use, sleep duration, age and weight of the respondents. Conclusions: The high prevalence of spectacle use warrants further studies for establishing the pattern of change in refractive errors and behavioural habits.

Awareness of childhood blindness in parents attending Paediatrics Ophthalmology outpatient department

Background: Blindness is defined by World Health Organisation as having a visual acuity of <3/60 in the better eye. Thirty-seven million people are blind worldwide. One million and four hundred thousand are children. The causes of blindness in children vary according to region and socioeconomic development. The aim of our study is to identify a range of potential issues relating to parental awareness and perceptions of common eye diseases affecting children. Materials and Methods: The type of study was population-based, prospective, cross-sectional study conducted on parents of 200 children ranging from 0 to 16 years of age, attending Paediatric Ophthalmology clinic during the month of August and September 2014. This was an open-ended questionnaire-based study and only the participants who consented were enrolled in the study. Results: The most common eye problem detected among 200 of children was refractive errors. The incidence of refractive errors was found to be 103 out of 200 (51.5%). This is followed by 71 (35.5%) cases of squint/strabismus. Of 200 parents, 150 (75%) think the present eye condition of their child will reduce the eyesight. However, they did not know about the nature of the eye problem. Forty-four (22%) parents did not know anything about the eye condition of their child. Seventy (35%) parents were apprehensive about the use of spectacles in the children suffering from refractive errors. One hundred and six (53%) parents came to know about the eye problem of their child from the teacher of the child and 63 (31.5%) parents got information from their family doctor. Conclusions: As the number of mothers attending the eye department with the child is high, so there is more need of educating the mothers about the eye conditions of the child. Education and socioeconomic conditions affect the knowledge and awareness level of the parents regarding eye problems. Most of the children attending outpatient department were found to be in the age group of 5-8 years. This may point toward factors like dietary deficiency of Vitamin A and other important nutrients. Commonest eye problem was of refractive errors among children.

Topical Atropine in the Control of Myopia.

Efforts to reduce myopia progression in childhood are driven by the increasing incidence of high myopia and its attendant health risks. Interventional approaches to reduce myopia progression in childhood have included the use of spectacles, contact lens, and pharmacological methods, of which the latter appear to be most promising. We review the use of topical atropine eye drops in the retardation of myopia progression in children and discuss the efficacy and safety profiles when used at different concentrations (1.0%, 0.5%, 0.1%, and 0.01%). Topical atropine reduces myopia progression and axial elongation in children in a dose-related manner, but a rebound phenomenon occurs with higher doses. Its use has been shown to be safe, but higher doses cause pupil dilation, loss of accommodation and near vision. Atropine 0.01% has the best therapeutic index, with clinically insignificant amounts of pupil dilation, near vision, and accommodation loss but remains as effective as higher doses.

A More Natural Way of Seeing: Visual Performance of Three Presbyopia Correcting Intraocular Lenses

Purpose: To compare the visual and refractive outcomes, patient satisfaction and spectacle independence between three novel designs of diffractive IOLs. Method: Prospective study including 150 patients with implantation of three IOLs: trifocal diffractive IOL AT LISA tri 839 MP (ATLISA, n = 50), trifocal diffractive IOL PhysIOL FineVision (FineVision, n = 50) and the extended range of vision IOL Tecnis Symfony ZRX00 (Symfony, n = 50). Patients were followed up for 6 months after surgery. Major parameters were monocular and binocular uncorrected (UDVA) and corrected (CDVA) distance, uncorrected (UIVA) and distance corrected (DCIVA) intermediate (80 cm), and uncorrected (UNVA) and distance corrected (DCNVA) near (40 cm) visual acuities (UNVA), contrast sensitivity (CS), defocus curve as well as patient satisfaction and spectacle use. Results: Mean postoperative decimal UDVA was 1.01 for Symfony, 0.96 for ATLISA and 0.95 for the FineVision IOL. Postoperative UIVA was 0.95 with Symfony, 0.72 with ATLISA and 0.85 with the FineVision IOL. Postoperative UNVA was 0.96 with the FineVision, 0.72 with the ATLISA and 0.63 with the Symfony IOL. The Symfony defocus curve showed the smoothest profile. Mean mesopic CS was 0.84 log units with the Symfony, 0.83 with the ATLISA (0.83) and 0.65 with the FineVision IOL. Mean photopic CS with the Symfony, ATLISA and FineVision was 1.05, 0.85 and 0.69 log units, respectively. Twenty percent of the patients with the ATLISA and FineVision IOLs and 5.6% of the Symfony patients reported halos and glare as troublesome or disabling. Reading glasses were frequently used by 5.6% of the Symfony patients. All patients with the trifocal IOLs reported to be spectacle-free for any distance. Conclusion: All 3 IOLs produce excellent results with high levels of spectacle independence. The Symfony produces better levels of distance and intermediate visual acuity, whereas the trifocal IOLs produced better near vision. Higher frequency of dysphotopsia was seen with the trifocal IOLs.

Self‐recognition of recurrences among patients with exudative age‐related macular degeneration

PurposeThe aim was to investigate factors influencing a patient's self‐recognition of the recurrence of exudative changes secondary to age‐related macular degeneration (AMD).MethodsIn this retrospective study, we reviewed medical records for patients with exudative AMD who were diagnosed with a recurrence of exudation. Various parameters were compared, including age, sex, diagnosis, spectacle use, visual acuity before and after the recurrence and the extent of the decrease in visual acuity. In addition, visual acuity and unaided vision before the recurrence were compared in patients who did not use eyeglasses.ResultsForty‐eight eyes from 48 patients were included in the analysis. Twenty‐seven patients (56.3 per cent) identified a decrease in visual acuity. These patients had better visual acuity before the recurrence (p = 0.023) and reported a greater decrease in visual acuity (p = 0.005) than patients who did not identify a visual change. Patients who wore spectacles were also more likely to notice the change in their visual acuity (p = 0.027). Visual acuity was significantly better than uncorrected vision (p < 0.001).ConclusionsPatients who do not use eyeglasses or who have relatively poor vision tend not to promptly recognise visual deterioration caused by the recurrence of exudation. Prescribing eyeglasses may facilitate accurate self‐recognition of the recurrence of exudation in cases where vision can be improved with correction.

The influence of the refractive correction on the vision-related quality of life in keratoconus patients.

The aim of this study was to assess the impact of refractive correction [spectacles vs rigid gas-permeable contact lenses (RGP CLs)] on the vision-related quality of life (VR-QoL) obtained with the standardized questionnaire, NEI-VFQ-25, in keratoconus patients compared with healthy myopic subjects. The Spanish version of NEI-VFQ-25 was administered two consecutive times to 25 keratoconus patients (RGP CL wearers) and 25 healthy myopic subjects (RGP and soft CL wearers). The first time was to assess the VR-QoL for spectacle wearing, such as those for refractive correction, and the second time was for CL wearing. Keratoconus patients showed a lower VR-QoL impairment (P < 0.01) than healthy subjects in the total and all subscale score of NEI-VFQ-25 related to wearing spectacles. With CL correction, keratoconus patients showed a VR-QoL improvement with statistically significant differences (P < 0.04) in only four subscales, including distance activities, mental health, color vision and peripheral vision, compared with healthy subjects. In the keratoconus group, compared to spectacle use, CL wear improved the VR-QoL score (P = 0.01) and all subscales except for ocular pain (P < 0.01) and mental health (P = 0.25). The use of the NEI-VFQ-25 to explore the difference in the VR-QoL between healthy subjects and patients with keratoconus provides further evidence of improved VR-QoL with RGP CL wear compared with spectacles in keratoconus patients. RGP CL management in keratoconus patients could minimize the impact of the disease on the patient's well-being.

Management of Keratoconus: Recent Trends

Keratoconus is a bilateral, progressive disease characterised by corneal thinning, ectasia, variable degree of irregular astigmatism and resultant mild to severe reduction in visual acuity. Multiple advances in corneal imaging and topographic mapping have led to a better understanding of the disease and its progression. Traditionally, use of spectacles and rigid contact lenses has been the primary mode of treatment in early KC while keratoplasty has been the treatment of choice in advanced cases. However, development of an array of therapeutic options over the last decade has revolutionized the approach to this disease. The preferred treatment for progressive KC has shown a paradigm shift from contact lens fitting for as long as tolerated, followed by Penetrating Keratoplasty (PK) or Deep anterior lamellar keratoplasty (DALK), to Ultraviolet-A (UV-A) induced collagen cross-linking (CXL) to stabilize corneal ectasia in the long term. Recently, use of Intrastromal Corneal Ring Segments, Phakic IOLs, application of excimer laser and use of combination techniques have all made significant contribution in providing options for effective management of different stages of this disease. Bowman layer (BL) transplantation is a new technique that has recently been introduced as an alternative to PK/ DALK in eyes with advanced KC, unsuitable for either UV-CXL or ICRS. By means of this article, we aim to provide a summary of these recent trends in therapeutic options for the optimal management of keratoconus.

Impact of Free Glasses and a Teacher Incentive on Children's Use of Eyeglasses: A Cluster-Randomized Controlled Trial.

To study the effect of free glasses combined with teacher incentives on in-school glasses wear among Chinese urban migrant children. Cluster-randomized controlled trial. Children with visual acuity (VA) ≤6/12 in either eye owing to refractive error in 94 randomly chosen primary schools underwent randomization by school to receive free glasses, education on their use, and a teacher incentive (Intervention), or glasses prescriptions only (Control). Intervention group teachers received a tablet computer if ≥80% of children given glasses wore them during unannounced visits 6 weeks and 6 months (main outcome) after intervention. Among 4376 children, 728 (16.7%, mean age 10.9 years, 51.0% boys) met enrollment criteria and were randomly allocated, 358 (49.2%, 47 schools) to Intervention and 370 (50.8%, 47 schools) to Control. Among these, 693 children (95.2%) completed the study and underwent analysis. Spectacle wear was significantly higher at 6 months among Intervention children (Observed [main outcome]: 68.3% vs 23.9%, adjusted odds ratio [OR] = 11.5, 95% confidence interval [CI] 5.91-22.5, P < .001; Self-reported: 90.6% vs 32.1%, OR = 43.7, 95% CI = 21.7-88.5, P < .001). Other predictors of observed wear at 6 months included baseline spectacle wear (P < .001), uncorrected VA <6/18 (P = .01), and parental spectacle wear (P = .02). The 6-month observed wear rate was only 41% among similar-aged children provided free glasses in our previous trial without teacher incentives. Free spectacles and teacher incentives maintain classroom wear in the large majority of children needing glasses over a school year. Low wear among Control children demonstrates the need for interventions.

12.1: Invited Paper: An Overview of Vision Realistic Rendering and Vision Correcting Displays

Vision‐realistic rendering is the computer generation of synthetic images that incorporate the characteristics of a par‐ ticular individual's entire optical system. Specifically, we simulate the scanned foveal image from wavefront data of actual human subjects.The concept of a vision correcting display involves digitally modifying the content of a display using measurements of the optical aberrations of the viewer's eye so that the display can be seen in sharp focus by the user without requiring the use of eyeglasses or contact lenses. Given the measurements of the optical aberrations of a user's eye, a vision correcting display will present a transformed image that when viewed by this individual will appear in sharp focus. Vision correction could be provided in some cases where spectacles are ineffective.

Use of Eyeglasses among Children in Elementary School: Perceptions, Behaviors, and Interventions Discussed by Parents, School Nurses, and Teachers during Focus Groups

To investigate the perceptions, behaviors, and recommendations that parents, school nurses, and teachers have regarding children's use of eyeglasses. Focus groups with parents, school nurses, and teachers were conducted. The study took place in one Southern California school district. There were 39 participants, including 24 parents, seven school nurses, and eight teachers. An experienced moderator guided the focus group discussions. Transcripts were analyzed using grounded theory techniques. Participants perceive visual impairment as a serious problem in the development of children. The lack of eyeglasses may lead to problems such as tiredness, headaches, inability to focus on school work, and decreased reading speed. Participants experienced disappointment, unhappiness, worry, and concern when they realized they needed eyeglasses at a young age. Negative societal perceptions toward eyeglasses, lack of eye doctors in minority communities, parental perceptions that children do not need eyeglasses, and peer bullying of children wearing eyeglasses are key obstacles to children's use of eyeglasses. Participants suggest school and national campaigns featuring respected public figures who wear eyeglasses to promote positive attitudes toward eyeglasses. Parents and teachers who closely follow the academic development of children have observed that visual impairment has negative consequences for the scholastic achievement of children. They recommend interventions to promote the attractiveness of eyeglasses in society. The participants discuss the need for a national preventative message for eye care similar to the message for dental care. The public health message should emphasize the importance of embracing and respecting differences among individuals.

Intermediate and near visual acuity of an aspheric, bifocal, diffractive multifocal intraocular lens with +3.25 D near addition.

To evaluate the clinical outcomes after cataract surgery with implantation of a new diffractive multifocal intraocular lens with a lower near addition. A prospective multicenter clinical study including 44 eyes of 44 patients (age range: 43 to 82 years) that underwent cataract surgery with implantation of the Tecnis ZLB00 multifocal intraocular lens (Abbott Medical Optics, Santa Ana, CA). Changes in uncorrected and corrected distance, intermediate, and near visual acuity, and manifest refraction were evaluated during a 3-month follow-up. Additionally, patients were asked about photic phenomena and spectacle dependence. Postoperative spherical equivalent was within 0.50 and ± 1.00 diopters of emmetropia in 91.2% and 100% of eyes, respectively. Postoperative monocular uncorrected distance, near, and intermediate visual acuities were 0.10 logMAR (20/25 Snellen) or better in 82.5%, 86.5%, and 68.8% of eyes, respectively. All eyes achieved monocular corrected distance and near visual acuity of 0.10 logMAR (20/25 Snellen) or better. All patients reported to be satisfied with the outcomes of the surgery. Only 6 patients (13.6%) required the use of spectacles for some daily activities postoperatively, and 8 patients (18.2%) reported mild perception of halos. The introduction of low addition multifocal intraocular lenses follows a trend to increase intermediate visual acuity. Still, a near addition of +3.25 diopters reached satisfying near results and led to high patient satisfaction.

Comparison of progressive addition lenses for general purpose and for computer vision: an office field study

BackgroundTwo types of progressive addition lenses (PALs) were compared in an office field study: 1. General purpose PALs with continuous clear vision between infinity and near reading distances and 2. Computer vision PALs with a wider zone of clear vision at the monitor and in near vision but no clear distance vision.MethodsTwenty‐three presbyopic participants wore each type of lens for two weeks in a double‐masked four‐week quasi‐experimental procedure that included an adaptation phase (Weeks 1 and 2) and a test phase (Weeks 3 and 4). Questionnaires on visual and musculoskeletal conditions as well as preferences regarding the type of lenses were administered. After eight more weeks of free use of the spectacles, the preferences were assessed again. The ergonomic conditions were analysed from photographs.ResultsHead inclination when looking at the monitor was significantly lower by 2.3 degrees with the computer vision PALs than with the general purpose PALs. Vision at the monitor was judged significantly better with computer PALs, while distance vision was judged better with general purpose PALs; however, the reported advantage of computer vision PALs differed in extent between participants. Accordingly, 61 per cent of the participants preferred the computer vision PALs, when asked without information about lens design. After full information about lens characteristics and additional eight weeks of free spectacle use, 44 per cent preferred the computer vision PALs.ConclusionOn average, computer vision PALs were rated significantly better with respect to vision at the monitor during the experimental part of the study. In the final forced‐choice ratings, approximately half of the participants preferred either the computer vision PAL or the general purpose PAL. Individual factors seem to play a role in this preference and in the rated advantage of computer vision PALs.

The long-term outcomes in children who are not compliant with spectacle treatment for accommodative esotropia.

To evaluate the long-term motor and sensory outcomes of children who have refractive accommodative esotropia and are noncompliant with spectacle wear. The medical records of patients diagnosed with pure refractive accommodative esotropia between 1999 and 2004 were retrospectively reviewed. All patients had hyperopia of at least 3 D and at least 1 year's follow-up. Patients were classified according to degree of compliance with spectacle wear as good, fair, and poor. The main outcome measures were sensory and motor outcomes. A total of 92 patients were included. The mean follow-up period was 61.4 months (range, 12-200 months). Compared to patients with good compliance, those with fair compliance had a significantly higher risk for poor sensory outcome (odds ratio [OR] = 4.56; 95% CI 2.1 - 24.7; P = 0.0003) and poor motor outcome (OR = 4.1; 95% CI, 1.44 -11.75; P = 0.0065). Patients with poor compliance likewise had a higher risk for poor sensory outcome (OR = 12.3; 95% CI, 1.29-96.79; P = 0.0061) and poor motor outcome (OR = 11.7; 95% CI, 2.38-74.19; P = 0.0006). Fair and poor compliance with spectacle use greatly increases the risk of poor sensory and motor outcomes in children with pure refractive accommodative esotropia.

Comparison of visual outcomes of 2 diffractive trifocal intraocular lenses

To compare the visual outcomes after cataract surgery with bilateral implantation of 1 of 2 diffractive trifocal intraocular lenses (IOLs). Two clinical centers, Lisbon, Portugal. Prospective comparative case series. Phacoemulsification with bilateral implantation of a Finevision Micro F IOL (Group 1) or an AT Lisa tri 839 MP IOL (Group 2) was performed. Over a 3-month follow-up, the main outcome measures were uncorrected distance visual acuity (UDVA), corrected monocular and binocular distance visual acuity, uncorrected intermediate visual acuity at 80 cm, distance-corrected intermediate visual acuity (DCIVA), uncorrected near visual acuity at 40 cm, distance-corrected near visual acuity (DCNVA), spherical equivalent (SE) refraction, defocus curves, contrast sensitivity, presence of dysphotopsia, and use of spectacles. Each group comprised 30 eyes (15 patients). The mean values at 3 months were UDVA, 0.03 logMAR ± 0.08 (SD) (Group 1) and 0.08 ± 0.12 (Group 2) (P = .765); DCIVA, 0.04 ± 0.07 logMAR and 0.18 ± 0.18 logMAR, respectively (P = .048); DCNVA, 0.03 ± 0.06 logMAR and 0.11 ± 0.08 logMAR, respectively (P = .032); SE, -0.25 ± 0.30 diopter (D) and -0.02 ± 0.39 D, respectively (P = .087). There was no significant difference in contrast sensitivity or dysphotopic phenomena between groups. Both trifocal IOL models provided excellent distance, intermediate, and near visual outcomes. Monocular DCIVA and DCNVA appeared slightly better in Group 1. Predictability of the refractive results and optical performance were excellent, and all patients achieved spectacle independence. Neither author has a financial or proprietary interest in any material or method mentioned.

Visual Acuity and its Relationship with Lifestyles among Students

The aim of the study is to assess visual acuity and its relationship with lifestyles among school children (10–16 years) at selected schools of District Faridkot, Punjab. A descriptive non experimental research design was used to conduct the present study. Convenient sampling technique was used to select 500 school children to assess visual acuity and lifestyles. Snellen chart was used to assess visual acuity and interview schedule with Likert scale was used to assess the lifestyles i.e. reading and writing habits, TV watching, Computer use, games, sleep, eye health practices and nutrition of school children. The findings revealed that out of 500 subjects, 92 (18.4%) study subjects had abnormal visual acuity i.e. <6/6 and 114 (22.8%) study subjects had poor lifestyle. A statistically significant relationship was found between visual acuity and lifestyle of subjects at p<0.05. Visual acuity was found to be associated with age, spectacle use among brothers/sisters of subjects, history of headache and eye discharge and ability to see and follow writing of class teacher on blackboard at p<0.05. Lifestyles was also found to be associated with age, history of headache and eye discharge and ability to see and follow writing of class teacher on blackboard at p<0.05. The study concluded that presence of abnormal visual acuity is quite more and visual acuity is also affected by lifestyles among school children.

Do We Need an Eye-Shield in Our Cath-Labs?

Posterior sub-capsular cataract is emerging as a late adverse effect of radiation exposure in cardiac invasive laboratories and with the expansion of percutaneous cinefluoroscopy-guided treatment modalities in the near-future it would continue to be a potential source of professional hazard for cath-lab staff. The importance of posterior sub-capsular cataracts could be viewed from two aspects; first, this form of lens involvement tends to be associated with higher degree of vision impairment as it affects parts of the lens located on the visual axis (1). Secondly, radiation-related cataracts implies higher accumulative X-ray exposure and possibly a higher chance of cancer according to linear-no threshold model. Although studies have shown that lead glasses with side-shield or roof-suspended plastic shields dramatically reduce the cumulative absorbed dose of the eyes, there is no firm evidence that use of eye protection has a significant reduction in the rate of cataracts in long-term. There are some points in the recently published study by Rajabi et al. (2) that should be discussed in more detail: In the mentioned study, the incidence of cataracts in staff was 79%, which is considerably higher than previous reported rates of around 50% (3). In those personnel working in electrophysiology laboratory, the received dose was four to five times higher than the average dose of other laboratories. This implies the need for better shielding and optimization of fluoroscopic time by staff. Only 30% of personnel reported routine use of lead eye glasses in this study. Although it was not proved that eye protection would reduce long-term risk of cataracts, considering very high rate of lens involvement in invasive laboratory staff and the ease of use and high efficacy of lead glasses to reduce the absorbed lens dose, it is reasonable to consider eye protection in our local guidelines or policy procedures. Finally, designing a clinical trial to study long-term biologic effects of radiation is very difficult, since it needs very large sample size and takes a long time to observe the effects in question (4). On the other hand, measures to optimize the radiation exposure to staff are simple and relatively cheap. Therefore, until there would be enough evidence about the true impact of eye protection in cath-lab, it is better to remain on the safe side and wear eye glasses.
