Retrospective Case Series on The Enduring Rotational Stability of The AcrySof IQ Toric Intraocular Lens in Cataract Patients Suffering from Myopia

Objective: To analyze the enduring rotational steadiness of AcrySof IQ Toric intraocular lens (IOL) in cataract patients suffering from myopia in a long-term study. Methods: A retrospective study was conducted on a case series involving 78 patients. A total of 120 eyes with an axial length (AL) ranging from 24–30 mm and corneal astigmatism ≥ 1.50 D underwent implantation of AcrySof IQ Toric IOL guided by the version navigation system. The eyes were divided into two groups based on AL. Group A included 60 eyes with high myopia (AL ≥ 26 mm), while Group B consisted of eyes with low to moderate myopia (24 mm ≤ AL < 26 mm). Data on the preoperative AL were collected. Measurements were taken for residual astigmatism, the best corrected visual acuity (BCDVA), corneal astigmatism, and IOL rotation occurring between 24- and 48-months post-surgery. The percentage of eyes with an IOL rotation of under 5° and 10° was analyzed. Results: The mean length of follow-up times was recorded as 34.27 ± 4.98, and the average rotation was 2.73 ± 1.29°. Group A exhibited a slightly higher average rotation of 2.87 ± 1.31°, compared to the rotation of 2.59 ± 1.27° observed in Group B. At both the 24–36 month and 26–48 month post-operation marks, the degree of IOL rotation did not show a statistically significant difference between the two groups, with none of the patients experiencing a rotation exceeding 10° (P > 0.05). The percentage of rotation degrees under 5° was recorded as 98.22%. After the procedure, the BCDVA was 0.13 ± 0.03 LogMAR. There was a substantial increase in the χ2 value after the operation as compared to the pre-operative χ2 value (χ2 = 76.79). The standard deviation of preoperative corneal astigmatism was statistically significant (P < 0.05) at 2.17 ± 1.08 D. Following the surgical procedure, the remaining astigmatism was measured at 0.41 ± 0.26 D. The data showed a notable gap in statistical significance (t = 4.281, P < 0.05). Conclusion: The AcrySof Toric IOL was a reliable solution for managing corneal astigmatism in cataract patients with myopia, demonstrating excellent long-term rotational stability.

Corneal Astigmatism in Cataract.

To measure preoperative corneal astigmatism in cataract patients. Descriptive study. Place and Duration of the Study: Mughal Eye Hospital, Lahore, from 2018 to 2022. The amount of preoperative corneal astigmatism was noted in cataract patients. Inclusion criteria included cataract patients above 16 years of age. Exclusion criteria included any preexisting corneal pathology (including corneal scar, corneal oedema, pterygium, etc.) and any previous ocular surgery, e.g. trabeculectomy, pterygium excision. SPSS version 25 was used for recording the data. Descriptive statistics were determined for demographic data and keratometry variables. Range of corneal astigmatism was zero to 5.75 dioptre with a mean of 1.05 dioptre (D) and standard deviation of 0.83. Corneal astigmatism of one or less than one diopter was recorded in 468 eyes (66.7%). Corneal astigmatism of 1.1 to 2 D was noted in 166 eyes (23.6%). Forty-nine eyes (7%) had corneal astigmatism of 2.1 to 3.0 D. Corneal astigmatism of 3.1 to 4.0 D, 4.1 to 5.0 D and 5.1 to 6 D was encountered in 11 (1.6%), 5 (0.7%) and 3 (0.4%) eyes respectively. A marked proportion of patients undergoing cataract operation have corneal astigmatism, so the phacoemulsification surgeon should consider difference of keratometry findings preoperatively.

Effect of femtosecond laser-assisted arcuate keratotomy versus toric intraocular lens implantation on correction of astigmatism in cataract surgery: a systematic review and meta-analysis.

To compare the efficacy of femtosecond laser-assisted arcuate keratotomy (FSAK) combined with non-toric intraocular lens (IOL) implantation versus Toric IOL (TIOL) implantation in correcting corneal astigmatism in cataract patients. Relevant literature was searched in databases including PubMed, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and SinoMed. Data from the included studies were extracted. A meta-analysis was conducted to compare the correction performance of FSAK combined with non-toric IOL implantation and TIOL implantation using postoperative refractive astigmatism, correction index, and uncorrected distance visual acuity (UDVA) outcomes. Publication bias assessment and sensitivity analysis were also performed. Five comparative studies were ultimately included in the meta-analysis. The TIOL group had smaller postoperative refractive astigmatism and a greater correction index compared to the FSAK group. The mean differences in postoperative refractive astigmatism and correction index between the two groups were - 0.19D (95% CI = 0.12 to 0.26, P < 0.01, I2 = 7%) and - 0.09 (95% CI = - 0.18 to 0.00, P = 0.04, I2 = 0%), respectively. We found no statistically significant difference in UDVA between the two groups (95% CI = - 0.01 to 0.11, P = 0.09, I2 = 70%). FSAK combined with non-toric IOL implantation was found to be less effective than TIOL implantation in correcting preoperative corneal astigmatism in cataract patients. The difference in the effectiveness of astigmatism correction between the two surgical methods seems to diminish, as the degree of preoperative corneal astigmatism decreases.

Simultaneous Presbyopia and Astigmatism Correction with a Novel Trifocal Toric Intraocular Lens-A One-Year Follow-Up.

The current investigation evaluates the efficiency of the trifocal toric Liberty 677MTY intraocular lens (IOL) in correcting preoperative corneal astigmatism in cataract patients demanding spectacle independence. The retrospective evaluation included 28 eyes of 15 patients with preoperative corneal astigmatism of at least 1.0 Dioptre (D). All patients were followed up for one year postoperatively. Residual refractive errors and visual acuities at multiple distances were measured. Binocular visual acuity and contrast sensitivity defocus curves were plotted. Visual functions and patient satisfaction were assessed. The efficiency of astigmatism correction was determined using the vector analysis method. The mean spherical equivalent refraction (SEQ) improved from 2.72 ± 1.62 D to 0.10 ± 0.48 D. The cylindric refraction decreased from 1.18 ± 0.45 D to 0.16 ± 0.31 D. Vector analysis proved efficient astigmatism correction with a centroid of 0.10 ± 0.34 D at 161°. Ninety-two percent of eyes resulted within 0.5 D from the target refraction. Visual acuities were 0.1 logMAR or better from +1.0 to −3.5 D defocus values. Visual tasks could be performed without major difficulties. Our patients were highly satisfied. Refractive and visual outcomes with the investigated presbyopia-correcting toric IOL are predictable and the lens provides excellent trifocal vision.

Comparison of optical low coherence interferometry and Scheimpflug imaging combined with partial coherence interferometry biometers in cataract eyes.

PURPOSE:The purpose of the study was to evaluate the agreement between measurements by optical low-coherence interferometry (OLCI, Aladdin) and those by Scheimpflug imaging combined with partial coherence interferometry (Scheimpflug-PCI, Pentacam AXL) in cataract patients.METHODS:This was a retrospective comparative study conducted in the United Arab Emirates. Axial length (AL), corneal power (keratometry, K), anterior chamber depth (ACD), and corneal astigmatism in patients with cataracts were measured with both devices. Difference and correlation were evaluated with paired t-test (p) and Pearson's correlation coefficient®, respectively.RESULTS:A total of 164 eyes of 95 patients were analyzed (164 eyes for K, 155 for ACD, and 112 for AL). The mean AL taken by OLCI was longer than that by Scheimpflug-PCI (23.25 mm vs. 23.23 mm, P ≤ 0.0001), showing an excellent correlation between the two (r = 0.9990). ACD measured by OLCI was 0.08 mm shallower than that by Scheimpflug-PCI (P = 0.0003, r = 0.7386). Corneal power measured by OLCI was lower than that by Scheimpflug-PCI (differences in mean K, flat K, and steep K were 0.05 diopters (D), 0.08 D, and 0.02 D, respectively), showing very strong correlations between the two devices (r = 0.9614, 0.9445, and 0.9535, respectively). Only flat K values measured with the two devices were significantly different (P = 0.0428). There were no statistically significant differences in the magnitude of astigmatism or J45 vector between the two devices (P = 0.1441 and P = 0.4147, respectively). However, J0 vector values were significantly different (P = 0.0087).CONCLUSION:Although OCLI and Scheimpflug-PCI showed strong correlations for measurements of AL, K, ACD, and corneal astigmatism in cataract patients, there were small but statistically significant differences in AL, ACD, flat K, and J0 vector. Thus, these two devices are not interchangeable for calculating intraocular lens power.

Astigmat Kornea Pada Penderita Katarak

Corneal astigmatism in cataract patients can cause poor visions after cataract surgery. Patients could have optimum visions without glasses by toric IOL implants during cataract surgery. This study aimed to find the distribution of corneal astigmatism in cataract patients based on age, gender, race, type of astigmatism, and astigmatism level. This study was a descriptive prospective study with cross sectional design with 550 eyes from 556 patients. The samples were collected from eligible patient’s keratometric data in RSUD Arifin Achmad Provinsi Riau, RS Mata Pekanbaru Eye Center, and RS Bina Kasih Pekanbaru. The results of the study showed 60.9% of cataract patients had corneal astigmatism and 61.7% of patients with astigmatic (37.2% of cataract patients) were moderate, severe, and extreme astigmatic that required correction with toric IOL. Most of the ages were 60-69 years old (42.2%). The characteristic of the patients was dominated by men (51.6%). The most common race is Malay Mongoloid (97.6%). The most type of astigmatism is astigmatism with the rule (ATR) (42.9%).

Distribution and internal correlations of corneal astigmatism in cataract patients

The aim of the study is to explore the distribution patterns and internal correlations of the morphological parameters of the cornea in patients with age-related cataract. The Pentacam HR was used to measure anterior corneal astigmatism (ACA), posterior corneal astigmatism (PCA), total corneal astigmatism (TCA) and keratometric corneal astigmatism (KCA). With age, the proportion of with-the-rule (WTR) ACA decreased from 65.31% to 23.63%, while the against-the-rule (ATR) ACA increased from 26.53% to 56.20%. PCA exceeded 0.50 D in 9.14% of eyes, while 76.35% of them were ATR. The magnitude of ACA was positively correlated with PCA in the whole sample, with a more significant correlation in WTR eyes (sr = 0.349, P < 0.001). The vector summation effect of PCA to ACA changed from compensation to augmentation with aging. In 57.53% of WTR eyes, KCA was overestimated by an average of 0.21 ± 0.17 D, while it was underestimated by 0.38 ± 0.27 D in 87.62% of ATR eyes. In conclusion, among age-related cataract patients, ACA and TCA gradually shifted from WTR to ATR with aging, while most PCA remained as ATR. Ignoring the age-related changes and real PCA might cause overestimation of WTR astigmatism and underestimation of ATR astigmatism.

Efficacy comparison between toric intraocular lens and aspheric intraocular lens plus steep-axis incision in cataract patients with low corneal astigmatism.

The present study aimed to evaluate and compare the efficacy of toric intraocular lens (IOL) implantation and aspheric IOL implantation with steep-axis incision for correcting mild to moderate corneal astigmatism in cataract patients. A prospective, single-center, open label, randomized, two-arm study was designed. Cataract patients with corneal astigmatism of 1.0-2.0D were enrolled and divided into test and control groups. The test group had the AcrySof® IQ Toric IOL implanted and the control group had the AcrySof® IQ IOL implanted with a steep-axis corneal incision. All patients underwent examinations of uncorrected distance visual acuity (UCDVA), corrected distance visual acuity (CDVA), subjective refraction, and corneal astigmatism before surgery and at the 1-day, 1-month, and 3-month follow-ups. Vector astigmatism analysis was evaluated using the Alpins method. We enrolled 26 eyes of 20 patients in the study, with 13 eyes in each group. The test group had better vision than the control group at the 3-month follow-up and had more cases with a UCDVA of 20/20 (10/13 vs. 4/13). The surgically induced astigmatism (SIA) vector of the test group was higher than that of the control group (1.22±0.64 vs. 0.84±0.45). The correction index of the test group was closer to 1 compared to that of the control group (0.7 vs. 0.46). Approximately 85% of patients in the test group had an angle of error within -15° to 15°. However, only 23% of patients in the control group were within that range. Though steep-axis corneal incision was cost-saving and easy-to perform, its astigmatismcorrecting efficacy was not as good as the Toric IOL implantation for cataract patients with low to moderate corneal astigmatism.

Toric Intraocular Lens Implantation in the Correction of Moderate-To-High Corneal Astigmatism in Cataract Patients: Clinical Efficacy and Safety.

Methods A total of 57 cataract patients (57 eyes) with regular corneal astigmatism (≥2.57 D) were enrolled in this retrospective cohort study. Phacoemulsification with toric IOL implantation was performed for all patients. The uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) were recorded before and one year after surgery, and statistical analysis of preoperative corneal astigmatism, postoperative residual astigmatism, aberrations, IOL rotation, and related factors was performed to evaluate the efficacy, safety, and stability of toric IOLs in correcting moderate-to-high corneal astigmatism. Results One year after surgery, visual acuity was significantly improved compared with that before surgery (preoperative log MAR 0.87 ± 0.34 vs. postoperative log MAR 0.31 ± 0.26, p < 0.001), and the self-reported spectacle independence rate was 68.42%. The total residual astigmatism was 1.18 ± 0.85 D, which was significantly less than the preoperative value (3.41 ± 0.99 D) (p < 0.001). The degree of toric IOL rotation was 4.93 ± 3.02°, and 54.39% of patients had a lens rotation of less than 5°. The IOLs of 5.26% (3 eyes) of patients rotated more than 10°, and these patients received glasses instead of undergoing IOL repositioning. Conclusions Toric IOL implantation provided optimal vision outcomes and low spectacle dependence during a one-year follow-up period. The results from our study show that toric IOL implantation is a safe and effective option for cataract patients with moderate-to-high corneal astigmatism.

Comparison of Surgically Induced Corneal Astigmatism in Cataract Patients after Phacoemulsification Versus Manual Small-Incision Cataract Surgery

The advances in cataract surgery are aimed at finding a surgical method capable of providing accurate andpredictable results in terms of outcome. Surgically Induced Astigmatism (SIA) is one of the causes of the poorquality of vision post-operatively because of the blurring of images. SIA in turn, depends on the type, lengthand the position of the incision.so this study to compare the mean keratometeric reading preoperative andone month postoperative in phacoemulsification versus manual small-incision cataract surgery and to findwhich produce less surgically induced astigmatism. This was a prospective, observational, cohort study onpatient with cataract carried out from April 2018 to September 2018. This study conducted on (206) patientsattending to ophthalmic department in Najaf. The cases were divided into two groups. Each group had 103patients. One group had undergone phacoemulsification and the other group had undergone superior scleraltunnel incision and follow up after one month to find which procedure less surgically induced astigmatism.Preoperative and postoperative keratometeric was performed after one month. According to this study meankeratometeric reading in the Phaco group preoperative k1= 43. 80, k 2= 44.69 and postoperative k1 =43.71and K2 =44.62.While Mean keratometeric reading in the SSTI group preoperative k1=44.00, K2 =45.02 and postoperative k1 =43.91 and K2= 45.41.Mean astigmatism at one month postoperative in patient undergoing Phaco was 1.3 ±0.9 and undergoingSSTI was 1.3± 0.7, there was no statistical difference in astigmatism at one month postoperative (P=0.5).This study reveals that superior approach in PHACO and MSICS produced similar astigmatic outcome,there is no significant difference in the mean surgically induced astigmatism in both types of surgery

Toric intraocular lens for correction of high corneal astigmatism in cataract patients

AIM: To evaluate the efficacy of Bi-Flex toric intraocular lens (T-IOL; Medicontur, Medical Engineering, Ltd., Inc.) implantation to correct preexisting astigmatism in patients having cataract surgery. METHODS: This retrospective consecutive study included 22 eyes of 16 patients with more than 2.50 diopters (D) of corneal preexisting astigmatism having cataract. Preoperative and postoperative uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), objective and subjective refraction and keratometric and topographic cylinder were measured. Postoperative the toric IOL axis was evaluated using vector analysis. RESULTS: Postoperatively, subjective refractive cylinder was reduced significant (P&lt;0.05) from 4.05±1.53 D to 1.35±0.86 D. The component J0 reduced in magnitude from -0.81±2.02 D to -0.12±0.62 D (P&lt;0.05). Both, UCVA and BCVA improved significantly at 1mo after surgery (P&lt;0.05 in both cases). After the surgery, the UCVA and BCVA were 0.24±0.19 and 0.06±0.08, respectively. The mean toric IOL axis rotation was 2.95±5.25 degree, with rotation less than 10 degrees in 86.36% of eyes. No differences in mean keratometric values obtained before and after surgery were found (P&gt;0.05 for J0 and J45). CONCLUSION: Implantation of the Bi-Flex toric IOL is a safe and effective method to correct the preexisting regular astigmatism (greater than 2.50D).

Ocular Biometry and Corneal Astigmatism in Patients Undergoing Cataract Surgery in Bheri Zone of Nepal

Introduction: Accurate measurement of ocular axial length, keratometry and anterior chamber depth before cataract surgery is crucial for calculating the power of intraocular lens (IOL) to be implanted. Corneal astigmatism is one of the major thefts to have best postoperative unaided visual acuity. Thus, knowing it preoperatively and taking appropriate intervention during surgery provides best postoperative visual outcome. But there are no studies on corneal astigmatism and biometric parameters in the population of Bheri Zone.&#x0D; MATERIAL AND METHOD: The medical records of the patients who had ndergone cataract surgery between January 2017 and November 2017 at Nepalgunj medical college were retrospectively reviewed and analyzed. Patient's demographic parameter, keratometric value, anterior chamber depth, lens thickness and axial length data were collected and analyzed.&#x0D; RESULTS: This study evaluated the data in 65 eyes of 65 patients who had undergone cataract surgery. The mean age of patients was 59.3 ± 15.71 years. The mean corneal astigmatism was 1.37 D ±1.4D (range 0.00-6.75D). Corneal astigmatism was higher than 1.00 D in 32.3% of cases. The mean average keratometry was 44.54±1.83D. The magnitude of corneal astigmatism was positively correlated with age (p&lt;0. 001) and there was a tendency for corneal astigmatism to increase with age above 50 years. Against-the-rule regular astigmatism was the most common type (46.2%) of astigmatism observed in this study.&#x0D; CONCLUSION: The present report showed the pattern of corneal astigmatism before cataract surgery in the patients at Nepalgunj Medical College Teaching Hospital. One third of cataract patients had corneal astigmatism of more than 1.0D. This finding provide the important normative reference and help ophthalmologists to plan and manage the cost-effective correction of preexisting corneal astigmatism in cataract patients to achieve the best visual outcome.

Management of pre-existing regular astigmatism in phacoemulsification

Objectives The objective of this study was to compare the effect of single clear corneal incision (CCI) on the steep axis with opposite clear corneal incisions (OCCIs) on pre-existing regular corneal astigmatism in cataract patients having phacoemulsification. Background Correction of pre-existing regular astigmatism in phacoemulsification. Patients and methods This randomized prospective clinical study included 30 eyes of 30 cataract patients with corneal regular astigmatism greater than 1 D. The patients were randomly divided into two groups, each group involving 15 eyes. Paired 3 mm CCI were made on the steep axis in Group A and single in Group B. Preoperative evaluation included uncorrected visual acuity, refraction, best-corrected visual acuity, applanation tonometry, fundus examination, biometry, keratometry, and corneal topography. The vertical axis was marked before peribulbar anesthesia was given and routine phacoemulsification was performed through a 3-mm CCI on the steep axis. An additional opposite 3-mm self-sealing CCI was made opposite to the first one in Group A. Patients were examined 2, 4, and 8 weeks postoperatively. Visual acuity, refraction, keratometry, and corneal topography were used to evaluate the improvement. Results The mean preoperative and postoperative topographic corneal astigmatism was 1.95 D ± 0.83 (SD), 0.59 D ± 0.47 (SD) and 1.93 D ± 0.51 (SD), 1.53 D ± 0.62 (SD), respectively, in Groups A and B. There was a significant difference between the mean values of astigmatism in the two groups postoperatively. The mean surgically induced astigmatism, measured by a vector-corrected method, was 1.2 ± 80.11 D and 1.09 ± 0.13 D in Group A and Group B, respectively ( P = 0.00). The mean values of best-corrected visual acuity were 0.11 ± 0.13 in Group A and 0.22 ± 0.15 in Group B postoperatively ( P Conclusion OCCIs on the steep axis were more effective than single CCI in the correction of mild to moderate pre-existing corneal astigmatism.

Toric Intraocular Lenses in Cataract Surgery

Cylindrical deficits in patients with corneal astigmatism of 0.50 diopter (D) to 1.00D may influence visual acuity. Increasing age and cataract surgery are correlated with greater prevalence and extent of corneal astigmatism. Conventionally, spectacles and contact lenses have been used to improve or correct corneal astigmatism. However, increasing demand for freedom from spectacles for distance vision and high prevalence of pre-existing corneal astigmatism in cataract patients have forced cataract surgery for the correction of aphakia and pre-existing corneal astigmatism to become common practice. However, implantation of toric intraocular contact lenses (IOLs) into the eye during cataract surgery may be a more predictable, powerful, and stable way of correcting pre-operative corneal astigmatism and may provide an adjunct or alternative to spectacles or relaxing incisions. Early toric IOLs were associated with post-operative rotational stability, lens misalignment, and safety concerns. The use of the new AcrySof® IQ Toric IOL for the correction of aphakia and pre-existing corneal astigmatism has largely mitigated these concerns. In addition, the AcrySof® IQ Toric IOL may also replace other treatment options for correcting pre-existing corneal astigmatism in patients undergoing cataract surgery.

Long-Term Efficacy and Rotational Stability of AcrySof Toric Intraocular Lens Implantation in Cataract Surgery

PurposeTo evaluate the long-term efficacy and rotational stability of the AcrySof toric intraocular lens (IOL) in correcting preoperative astigmatism in cataract patients.MethodsThis prospective observational study included 30 eyes from 24 consecutive patients who underwent implantation of an AcrySof toric IOL with micro-coaxial cataract surgery between May 2008 and September 2008. Outcomes of visual acuity, refractive and keratometric astigmatism, and IOL rotation after 1 day, 1 month, 3 months, and long-term (mean, 13.3±5.0 months) follow-up were evaluated.ResultsAt final follow-up, 73.3% of eyes showed an uncorrected visual acuity of 20/25 or better. The postoperative keratometric value was not different from the preoperative value; mean refractive astigmatism was reduced to -0.28±0.38 diopter (D) from -1.28±0.48 D. The mean rotation of the toric IOL was 3.45±3.39 degrees at final follow-up. One eye (3.3%) exhibited IOL rotation of 10.3 degrees, the remaining eyes (96.7%) had IOL rotation of less than 10 degrees.ConclusionsEarly postoperative and long-term follow-up showed that implantation of the AcrySof toric IOL is an effective, safe, and predictable method for managing corneal astigmatism in cataract patients.

Astigmatism management in cataract surgery with the AcrySof toric intraocular lens

To present clinical data from a single-center prospective clinical trial of the AcrySof toric intraocular lens (IOL). Academic Hospital Maastricht, Maastricht, The Netherlands. Fifty-three eyes (43 patients) had implantation of an AcrySof toric IOL. Three toric models were evaluated in cylinder powers of 1.50 diopters (D) (SN60T3; T3 group, n = 16), 2.25 D (SN60T4; T4 group, n = 14), and 3.00 D (SN60T5; T5 group, n = 23) at the IOL plane. The T5 group was subdivided into eyes that could be fully corrected (T5a, n = 13) and eyes that could be partially corrected (T5b, n = 10). Four months postoperatively, the mean uncorrected visual acuity (UCVA) was 0.77 +/- 0.23 in the T3 group, 0.93 +/- 0.23 in the T4 group, 0.82 +/- 0.15 in the T5a group, and 0.47 +/- 0.13 in the T5b group. More than 90% of the combined eyes in the T3, T4, and T5a groups achieved a UCVA of 20/40 or better, and almost 80% achieved a UCVA of 20/25 or better. Residual refractive astigmatism of less than 0.75 D was achieved in 74% of eyes and of less than 1.00 D in 91%. The mean IOL misalignment was 2.5 +/- 2.1 degrees in the T3 group, 3.5 +/- 2.3 degrees in the T4 group, and 4.1 +/- 3.5 degrees in the T5 group. Implantation of the AcrySof toric IOL proved to be an effective, safe, and predictable method of managing corneal astigmatism in cataract patients.
