Clinical and biometric determinants of actual lens position after cataract surgery

To evaluate the preoperative clinical and biometric determinants associated with the actual lens position after cataract surgery. Department of Ophthalmology, University Hospital of Montpellier, France. Prospective longitudinal cohort study. The data collected included clinical factors (age, sex, history of vitrectomy) and biometry factors (axial length [AL], anterior chamber depth [ACD], lens thickness, white-to-white [WTW] distance) that might affect actual lens position. Each patient had optical low-coherence reflectometry biometry (Lenstar) preoperatively and 1month postoperatively. The actual lens position was measured as the postoperative position of the center of the intraocular lens (IOL). Patients were stratified into 3 groups by type of IOL: Acrysof SN60WF or SN6AT (Group 1), Tecnis ZCB00 or ZCT (Group 2), and Asphina 409MV (Group 3). The study comprised 168 eyes (mean age 73.3years±9.8 [SD]). The mean actual lens position was 4.88±0.29mm, 5.01±0.29mm, and 5.05±0.32mm in Group 1 (n=67 eyes), Group 2 (n=52 eyes), and Group 3 (n=49 eyes), respectively. In the overall population, AL, ACD, anterior segment depth, and WTW distance were correlated with actual lens position (r=0.48, P<.0001; r=0.64, P<.001; r=0.58, P<.0001; r=0.39, P<.001, respectively). The AL, ACD, anterior segment depth, and WTW distance correlated with actual lens position after cataract surgery. The integration of these data in IOL formulas could help improve refractive outcomes after the surgery.

Two single-piece acrylic intraocular lens choices and their effect on patient-reported driving habits

To determine whether intraocular lens (IOL) type affects patient driving habits 6months to 5years after cataract surgery, and to determine whether there were differences in self-reported driving habits between patients who received 1 of 2 IOLs. John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA. Retrospective case series. Patients completed a telephone-administered Driving Habits Questionnaire (DHQ) 6months to 5years afterhaving bilateral cataract surgery with a single-piece hydrophobic acrylic IOL, SN60WF (Group 1) or ZCB00 IOL (Group 2), in both eyes. The study comprised 260 patients (130 in each IOL group). Of these, 117 in Group 1 and 114 in Group 2 were still active drivers. The DHQ response differences for each IOL group did not reach statistical significance, except for self-rated quality of driving and difficulties with driving at night. Forthese significant differences, contradictory results were found. Patients with either of the monofocal IOLs had similar self-reported driving habits after bilateral cataract surgery. The choice of IOL did not affect patients' postoperative driving habits.

백내장 수술 후 수면 변화에 관한 통합적 고찰

Purpose: The purpose of this study was to review previous literature with an aim to explore the sleep disturbance level after a patient undergoes cataract surgery using an integrative review. Methods: We used the key words, ‘cataract surgery’, ‘sleep’, and ‘intraocular lens’ to find peer-reviewed publications in seven databases. Among 450 searched articles, eight articles were selected after exclusion of articles that did not meet the criteria. Results: Five of the articles submitted that subjective sleep quality of the patients with blue-filtering intraocular lens (BF-IOL) implant improved as compared to that before surgery. The change of saliva melatonin concentration after BF-IOL implant did not coincide in two of the articles. Two of the articles reported an increased level of intrinsically photosensitive retinal ganglion cells response after BF-IOL implantation. Conclusion: The published studies stated that BF-IOL implant did not have any negative impact on quality of sleep among cataract patients suffering with poor sleep. Rregardless of intraocular lens type, cataract surgery may increase photoreception of intrinsically photosensitive retinal ganglion cells one year after surgery although the mechanism was not clear. It is necessary to identify various factors influencing the quality of sleep such as gender and activities among cataract patients with BF-IOL implant in the future.

Management of sulcus-fixated single-piece intraocular lens-induced pigmentary glaucoma with 3-piece IOL exchange.

To describe our experience with exchanging sulcus-fixated single-piece intraocular lens (IOL) with 3-piece IOLs for management of pigmentary glaucoma. In this retrospective study, records of patients who underwent sulcus-fixated single-piece IOL exchanged with 3-piece IOLs were retrieved, and demographic and baseline data of patients, type of IOL, pre- and post-IOL exchange BCVA, IOP, number of anti-glaucoma medications, and optic nerve head examination were documented. Baseline and final examinations were analyzed and compared. Mean age of the patients was 59±10years, and 5 (41.6%) were female. Mean interval between primary cataract extraction operation and IOL exchange was 17±5months. Nine patients received in sulcus implantation of Alcon SA60AT, and three patients had SN60WF model at the end of primary surgery. BCVA changed insignificantly from 0.06±0.06 logMAR to 0.06±0.06 after IOL exchange. (P=0.22) IOP was controlled in 8 cases (66.6%), but four cases (33.3%) needed glaucoma surgery to further control glaucoma condition. IOP decreased significantly from preoperative 17±3 to 14±1mmHg postoperatively. Patients with advanced age and higher baseline IOP were more likely to undergo glaucoma surgery after IOL exchange. (P=0.07 and 0.00, respectively). single-piece IOL exchange with 3-piece IOL dramatically decreases pigment release and reduces IOP. Those with advanced age and higher IOP are less likely to respond to IOL exchange and may need glaucoma surgery to control high intraocular pressure.

Air bubble-induced intraocular lens opacification in hydrophobic intraocular lens following posttraumatic cataract surgery: A first-ever case report

A 19 year old male presented with complaints of diminution of vision in right eye. He had undergone cataract surgery in right eye elsewhere 6 years ago for firecracker injury. On examination, eccentric pupil is noticed with intraocular lens (IOL) opacity. on dilatation, rest of the intraocular lens is clear. As the rest of the IOL, which was protected by iris, was noted to be clear, the opacification at pupillary area suggests it to be secondary to air bubble contact .IOL exchange was done and explanted was tested and got confirmed as hydrophobic material. There are cases reports of IOL opacification post intra cameral air injection in hydrophilic lenses, to our knowledge this is the first case report of IOL opacification in hydrophobic lenses. with this case report we want to highlight the fact that one should be careful before intracameral air injection in eyes with both types of IOL.

Clinical and patient-reported outcomes of bilateral implantation of a +2.5 diopter multifocal intraocular lens

To assess the effectiveness and safety of a multifocal intraocular lens (IOL) with +2.5 diopter (D) additional power compared with a monofocal IOL. Fifteen sites in the United States. Prospective randomized patient- and observer-masked clinical trial. Randomized patients received multifocal or monofocal IOLs bilaterally. Visual acuity (33cm, 40cm, 53cm, 60cm, 4m) was measured; safety was assessed through adverse event rates. Patient-reported visual outcomes were evaluated using the Visual Tasks questionnaire. The frequency and severity of visual disturbances were evaluated using the Assessment of Photic Phenomena and Lens EffectS questionnaire. The multifocal IOL (n=155) provided better corrected distance visual acuity at 53cm than the monofocal IOL (n=165) (0.322 versus 0.512 logMAR; between-group difference, -0.190 logMAR; P<.0001) and 40cm but not at 4m. Ocular adverse event rates were less than 3.84% in both groups. Serious adverse event rates were comparable between the 2 IOL types. Patients with multifocal IOLs reported less difficulty with near tasks (with and without correction) and intermediate tasks (without correction). Difficulty with extended-intermediate and distance tasks was similar between groups. The most frequently reported self-rated severe phenomena were halos, starbursts, and glare. Most patients (monofocal ≥72%; multifocal ≥73%) reported never experiencing blurred, distorted, or double vision. The +2.5 D multifocal IOL provided better vision at 40 cm and 53cm and similar vision at 4m compared with the monofocal IOL. Safety profiles and visual phenomena were comparable between groups.

Predictors of Successful Laser Capsulotomy for Significant Posterior Capsule Opacification after Phacoemulsification.

Purpose:This study aimed to determine the reasons behind the failure of laser capsulotomy (LC) performed for significant posterior capsular opacification (PCO).Methods:Eighty-eight eyes of 88 patients referred for LC at a tertiary care center were retrospectively analyzed. The data recorded included the cause of cataract, visual acuity, duration of PCO, location of PCO, intraocular lens (IOL) position, IOL type, and lens capsule status. These data were later analyzed for determining the requirement of high pulse energy during LC and the success rate of primary LC.Results:The mean age of the participants was 55.77 ± 18.60 years with 58 (65.9%) male patients. The mean duration between cataract and LC surgeries was 45.58 ± 37.33 months. Senile (n=58), uveitic (n=12), post-pars plana vitrectomy (PPV) (n=12), and traumatic (n=6) cataracts were the common causes. Late-presenting PCO, trauma, uveitis, sulcus placement of IOLs, irregular capsulorhexis shape, and polymethyl methacrylate (PMMA) IOLs were significantly associated with unsuccessful LC and/or higher pulse energy settings during LC.Conclusion:Significant PCO is often associated with cataract caused by uveitis or trauma, and after PPV. PCO associated with trauma, sulcus placement of IOLs, and PMMA IOLs may need multiple LCs.

Residual Astigmatism Threshold and Patient Satisfaction with Bifocal, Trifocal and Extended Range of Vision Intraocular Lenses (IOLs)

Purpose: To compare the impact of induced astigmatism with four different types of multifocal intraocular lenses (MIOLs). Method: Prospective, comparative, interventional, mono-centered study, including 80 eyes of patients with implantation of four different MIOLs: AcrySof ReSTOR +2.5 D (20 eyes), AcrySof ReSTOR +3.0 D (20 eyes), AcrySof Panoptix (20 eyes) (Alcon Laboratories, Inc., Fort Worth, TX, USA), and Tecnis Symfony ZRX00 (Abbott Medical Optics, Santa Ana, USA) (20 eyes). Patients were followed up for 3 months after surgery. Major parameters were uncorrected (UDVA) and corrected (CDVA) distance visual acuity, subjective refraction and patient satisfaction. Results: Differences between IOLs with regard to the impact of the cylinder sign and axis on visual acuity and patient satisfaction were not significant. With mild added negative cylinder, AcrySof ReSTOR +2.5 D and Tecnis Symfony IOLs maintained the baseline visual acuity, while it was mildly reduced with AcrySof ReSTOR +3.0 D and Panoptix IOLs. With moderate induced cylinder, the Tecnis Symfony IOL maintained good visual acuity and patient associated satisfaction. Panoptix IOL was the IOL most affected by the induced astigmatism with regard to dissatisfaction and visual acuity. The highest tolerance to the astigmatic distortion and blurriness induced with a -1.50 D cylinder was obtained with the Tecnis Symfony IOL. Tecnis Symfony IOL showed less dissatisfaction and less reduction of visual acuity than the other MIOLs. Conclusion: Simulated residual cylinders after the implantation of the Tecnis Symfony IOL up to 1.0 D have a very mild and not clinically relevant impact on visual acuity or patient satisfaction. The ERV IOL showed a better tolerance to unexpected postoperative residual errors than diffractive bifocal and trifocal IOLs.

The Complexities of Negative Dysphotopsia.

The appearance of a dark shadow in the temporal periphery, otherwise known as negative dysphotopsia, continues to be a problem for some patients after routine uncomplicated cataract surgery. Etiologies include type and design of intraocular lens (IOL), anatomical features and dimensions of the eye, pupil size, angle kappa, relationship of the optic to the anterior capsule, and the position of the optic/haptic junction of the IOL. Although the primary etiology remains controversial, it is clear that the cause is multifactorial. All of the factors should be considered when attempting to prevent or treat this phenomenon.

Comparison between clinical outcomes of two different designs of toric multifocal intraocular lenses

To compare the clinical outcomes of plate haptic and open-loop haptic toric multifocal intraocular lenses (IOLs). In this retrospective, comparative clinical trial, two different designs of multifocal toric IOL were implanted in 49 eyes of 38 cases with corneal astigmatism ≥ 0.75 Diopter (D). The cases that underwent AcrySof IQ restore multifocal toric IOL (Alcon, open-loop-haptic) implantation were assigned to Group1 (n=19) and the cases that underwent Acriva Reviol multifocal toric IOL (VSY, plate-haptic) implantation were assigned to Group 2 (n=30). After surgery, the groups were compared in terms of degree of IOL rotation, residual spherical refraction and astigmatism and uncorrected near and distance visual acuity. With regard to the results of postoperative 1st month, 3rd month, 6th month and 1st year, no difference was determined in terms of uncorrected distance visual acuity, spherical equivalent (SE), degree of astigmatism (CYL), degree of rotation, and uncorrected near visual acuity (p>0.05). Significant increase was determined in all postoperative follow-up periods in terms of the distance and near visual acuity as compared to preoperative values (p0.05). Clinical outcomes of plate haptic Acriva Reviol multifocal toric IOL and open-loop haptic Acrysof IQ multifocal toric IOL are similar. Both types of IOL effectively reduce astigmatism and provide satisfactory uncorrected distance and near visual acuities.

Comparison of Anterior Capsule Stability Following Implantation of Three Single Piece Acrylic Intraocular Lenses with Different Haptic Design.

PurposeTo compare the anterior capsule contraction and intraocular lens (IOL) decentration among three types of IOL to determine the influence of haptic design on anterior capsule stability.MethodsOne hundred fifty patients were enrolled in this prospective, randomized study and 260 eyes underwent implantation of one of the following IOLs: modified L-haptic IOL (n = 74), modified C-haptic IOL (n = 97), or a plate-haptic IOL (n = 89). The area of the anterior capsule opening, IOL decentration, and capsule overlap were measured using retroillumination photospot 1 day and 2 months after cataract surgery.ResultsThe area of capsule opening at postoperative day 1 was significantly different between the three IOLs (p < 0.01). All IOLs showed reduction of the anterior capsule opening from 1 day to 2 months after surgery, and greater reduction was shown in the modified C-haptic IOL (p < 0.001). At postoperative month 2, IOL decentration was significantly different between the IOLs and showed a positive correlation with the mean area reduction during month 2.ConclusionsThe degree of anterior capsule contraction and IOL decentration in modified L-haptic IOLs were less than those in modified C-haptic IOLs and comparable to those in plate-haptic IOLs.

A computer system for the collection and analysis of information for cataract

Automation system for ophthalmologist proposed. The system allows to collect anamnesis(pre-history) using a questionnaire. Its use contributes to the early detection of cataracts. This system will allow the doctor to choose the possible types of intraocular lenses for phacoemulsification. Results of system work are shown.

Residual astigmatism after toric intraocular lens implantation: Analysis of data from an online toric intraocular lens back-calculator

To evaluate some possible causes for residual astigmatism after toric intraocular lens (IOL) implantation based on an analysis of data from an online toric IOL back-calculator. Retrospective data review. An online toric back-calculator was designed to allow users to input preoperative toric planning information along with postoperative IOL orientation and refractive results. These were then used to determine the optimum orientation of the IOL to reduce refractive astigmatism. The collected aggregate data were extracted from this calculator to investigate the associated reasons for residual astigmatic refractive error with toric IOLs. The study analyzed 12 812 records with a mean postoperative refractive astigmatism of 1.89 diopters (D). Refractive astigmatism was significantly higher with higher IOL cylinder power (P<.01) but was not different by IOL manufacturer. Ninety percent of IOLs were not at the ideal orientation, despite 30% being at the preoperative calculated orientation. Misalignment showed a directional bias for some IOLs but not for others. The mean calculated percentage reduction in residual cylinder after reorientation was 50%±31% (SD), with the magnitude of residual astigmatism after IOL reorientation expected to be 0.50 D or less in 37% of eyes (4835/12 812). Expected outcomes were significantly different by IOL type. Analysis of data from the online toric back-calculator provided insights into the nature of residual astigmatism after toric IOL implantation. The reasons for residual astigmatism in this data set varied by IOL type. Proprietary or commercial disclosures are listed after the references.

Neodymium:YAG capsulotomy rates associated with femtosecond laser–assisted versus manual cataract surgery

To compare the neodymium:YAG posterior capsulotomy rates after cataract surgery performed using a femtosecond laser system versus manual techniques. Pacific Hills Surgery Center, Laguna Hills, and La Veta Surgery Center, Orange, California, USA. Retrospective case study. After surgeries were completed between August 2011 and August 2014. A corrected distance visual acuity (CDVA) of 20/25 or better 1 to 3months after surgery was identified in a chart review and analyzed. Intraocular lens (IOL) type and power were recorded. Capsulotomies were recorded with the date of the procedure and the precapsulotomy CDVA. Capsulotomy rates related to manual capsulorhexis and capsulorhexis with a femtosecond laser system were compared, with consideration of IOL design and material. There was no statistically significant difference in posterior capsule opacification grade between surgery groups (P=.13). Capsulotomy rates were significantly lower in the femtosecond laser-assisted cataract surgery group than in the manual group (P=.04). The time between surgery and capsulotomy was statistically significantly lower in the femtosecond laser-assisted cataract surgery group (P<.01), which appeared to be a function of the higher ratio of multifocal IOLs in that group. There was a lower overall capsulotomy rate with hydrophobic acrylic IOL material than with hydrophilic IOL material. Neodymium:YAG capsulotomy rates were lower with femtosecond laser-assisted cataract surgery than with manual cataract surgery. The differences were more apparent in IOL material and design groups in which overall capsulotomy rates were lower.

Ocular residual astigmatism (ORA) in pre-cataract eyes prior to and after refractive lens exchange.

The purpose of this study was to analyze ocular residual astigmatism (ORA) before and after implantation of two different optical types of non-toric multifocal intraocular lenses (MIOL) in pre-cataract patients. This retrospective cohort study analyzed 72 eyes from 72 consecutive patients after MIOL surgery . To investigate magnitude and axis of astigmatic changes, the concepts of true corneal astigmatism and Alpins vector method were applied. There were no statistically significant between-group differences prior to surgery. The mean refractive surgically induced astigmatism (RSIA) (P=0.063) and the topographic SIA (TSIA) (P=0.828) did not differ significantly between the lenses, and the summated vector mean for ORA was reduced in terms of magnitude by approximately 0.30 Diopter. ORA in pseudophakic eyes mainly results from the posterior corneal surface and less from IOL tilting, postoperative posterior capsule shrinkage, or secondary cataract.

Intraocular lens exchange surgery at a tertiary referral center: Indications, complications, and visual outcomes

To identify indications for and visual outcomes of intraocular lens (IOL) exchange to understand recent changes in this surgery. Academic tertiary referral center. Retrospective case series. Cases were identified by searching the institution's electronic medical records from January 2010 to September 2015 for patients treated by 1 staff physician with the American Medical Association's Current Procedural Terminology code for IOL exchange. These cases were reviewed to determine the surgical indication, type of IOL removed, type of IOL implanted, time between surgeries, surgical complications, and visual outcomes. The study comprised medical records of 109 eyes. The mean time between the primary cataract surgery and IOL exchange was 1657days. Dislocation of an in-the-bag posterior chamber IOL (27.5%), intolerance of a multifocal IOL (18.3%), and uveitis-glaucoma-hyphema syndrome (11.9%) were the most frequent indications for IOL exchange. The final IOL position after exchange was most frequently in the capsular bag (43.1%), anterior chamber (25.7%), or sulcus(22%). The final visual acuity at 1month was 20/40 or better in 78.9% of cases. Of those not achieving this level of acuity, pathology not related to exchange surgery was identified in 48% of cases. The most frequent complications after IOL exchange surgery were posterior capsule opacification (13.8%), cystoid macular edema (10.1%), and high astigmatism (>1.5 diopters) (8.3%). The most frequent indication for IOL exchange surgery was dislocated IOLs; the second most frequent indication was patient dissatisfaction after multifocal IOL implantation. The increased ability to place an intracapsular IOL with few intraoperative complications and largely treatable postoperative complications enhances the effectiveness of IOL exchange surgery and patient satisfaction.

Special Intraocular Lenses in Refractive Lens Surgery

Many different models and types of special intraocular lenses (IOL) are now available for refractive lens surgery. In particular, toric and multifocal IOL need specific conditions to achieve satisfactory results. For multifocal IOL, many models with different optical principles are available. For optimal individual patient-centred care, it is necessary to consider several different options. With special refractive lenses, the principle objective for the patients is to become less dependent on glasses. Different IOL are evaluated on the basis of published studies and our own experience and data. IOL filtering blue light should not be classified as special IOL, but should be used as standards. Aspherical IOL are only beneficial in special situations. Toric IOL give reliable and good results, as long as certain specific requirements are considered. Multifocal IOL are still an optical compromise, although they are the only IOL that can reliably make the patient independent of glasses. To achieve satisfying results, the optimal IOL model should be selected individually. Many refractive needs can now be adequately satisfied by special IOL. The surgeon should provide ideal perioperative conditions, and he should be aware of the different IOL principles if he is to give the patient optimal advice. This can help to avoid upsetting both patients and ophthalmologists.

Standard manual capsulorhexis / Ultrasound phacoemulsification compared to femtosecond laser-assisted capsulorhexis and lens fragmentation in clear cornea small incision cataract surgery.

BackgroundFemtosecond-laser assisted clear cornea cataract surgery may hold promise in safer and more effective procedures. We decided to perform a comparative study to standard manual incision phacoemulsification surgery.MethodsThis is a single-center, single-intervention, and prospective comparative data evaluation of 133 consecutive cases subjected to cataract surgery. Group-A (Phaco), manual capsulorhexis & ultrasound phacoemulsification (n = 66); Group-B femtosecond-laser assisted capsulorhexis and lens fragmentation (n = 67), employing the LenSx laser (Alcon Surgical, Ft. Worth, TX). All cases were evaluated for refraction, visual acuity, keratometry, tomography, pachymetry, endothelial cell counts, intraocular pressure, and type of intraocular lens (IOL) implanted. The groups were matched for age, gender, pre-operative vision metrics, and cataract grade, and were followed up to 1 year.ResultsIn group-A post-operative uncorrected distance visual acuity (UDVA) was 20/20 or better in 61.5 % and 20/25 or better in 78.5 % of the eyes. The femtosecond laser group-B had improved outcomes (p = 0.075 and p = 0.042, respectively): post-operative UDVA was 20/20 or better in 62.7 % of the eyes and 20/25 or better in 85.1 %.Linear regression scatterplots of achieved versus attempted spherical equivalent had excellent regression coefficients (r2 = 0.983 in group-A and 0.979 in group-B). There were 75.2 % cases in group-A and 80.6 % in group-B (p = 0.8732) within ±0.50 D of targeted refractive equivalent. Slight trend of under-correction was noted in group-A. Average residual manifest cylinder in the toric subgroup-A was -0.50 D (95 % Limit-of-Agreement (LoA) = -0.78 D), and in toric subgroup-B -0.45 D (LoA = -0.45 D).ConclusionsMean spherical equivalent refraction and visual acuity are comparable with laser cataract surgery compared with manual capsulorhexis & ultrasound phacoemulsification. Improved astigmatism correction may be among the benefits of femtosecond laser–assisted cataract surgery. Transient corneal edema may be a first day transient disadvantage in femtosecond laser–assisted cataract surgery.

Outcomes of cataract operations in extreme high axial myopia.

To analyse the outcomes of phacoemulsification in extreme axial myopia Consecutive cases of phacoemulsification in eyes with axial length ≥ 30.0mm from January 1, 2010 to Dec 31, 2013 in a tertiary referral eye hospital were retrospectively reviewed. A single intraocular lens (IOL) type was used for all cases. Main outcome measures included perioperative complications and refractive outcome. Two hundred and twenty-one eyes were identified. Intraoperatively, two eyes (0.9%) had unstable capsular bag and three (1.4%) had posterior capsular rupture. At a mean follow-up duration was 27.4 ± 14.6months, three eyes (1.5% of 198 eyes with no history of retinal detachment or macular hole) developed retinal detachment. There was an overall hyperopic shift with a mean biometry error of 0.45 ± 1.21 D in all eyes. The mean absolute biometry prediction error was 0.98 ± 0.83 D in all eyes, 1.11 ± 0.86 D and 0.85 ± 0.82 D in eyes receiving negative- and positive-power IOL, respectively (p = 0.042). A total of 61.2% of eyes had refractive outcome within ± 1.0 D of target spherical equivalent. Regression analysis showed low IOL power as an independent predictor for greater postoperative absolute biometry error (p = 0.014). We showed no increase in perioperative complications in eyes with extreme high axial myopia. In eyes with long axial length, implantation of IOL with lower power was associated with more hyperopic shift, which was more pronounced with negative-power IOL.

The surgery correction of presbyopia: the modern possibilities

The article presents review of actual publications' data concerning surgical correction of presbyopia. The data is presented related to social significance of presbyopia alongside with other disorders of refraction. The techniques applying monovision include thermokeratoplasty and such its modification as laser and radio-frequency thermokeratoplasty. All of them have number of deficiencies. The exdmer-laser ablation of cornea in the form of Laser-Assisted in Situ Keratomileusis (LASIK) or Photorefractive keratectomy (PRK) are considered as kerato-refractional techniques of correction of presbyopia. The femtosecond laser intrastromal correction of presbyopia (INTRACOR) is also labeled as kerato-refractional technique of correction of presbyopia and it is based on making intrastromal concentric rings in the central optical zone of cornea. The deficiency of INTRACOR is a relatively high cost of procedure due to application of femtosecond laser. The implantation of inlays (artificial devices) into cornea permits correcting presbyopia with less financial expenses. However, there are number of contraindications for implementing. The Tornton and Schachar operations are referred to the group of sclerotic operations of correcting presbyopia. However, nowadays these interventions are practically out of application. The implantation of intraocular lenses, including accommodating, multi-focal and monofocal by the principle of monovision ones, can be considered as the most adequate mode of correction of presbyopia. The advantages and disadvantages of implantation of various types of intraocular lenses are considered in detail.
