Purpose: To evaluate the clinical outcomes and quality of life following implantation of PanOptix toric intraocular lens (IOL) and to compare the outcomes following femtosecond laser assisted cataract surgery (FLACS) and standard cataract surgery (SCS). Methods: This comparative retrospective study included 79 eyes of 55 patients underwent cataract or refractive lens exchange surgery between April 2017 and January 2020 in Bayindir Hospital and Kaskaloglu Eye Hospital. Corneal (CA) and refractive astigmatism (RA), uncorrected visual acuities for distant, intermediate, and near (UDVA, UIVA, and UNVA), low contrast distance visual acuity, rotational stability, defocus curves, photopic and mesopic contrast sensitivity (CS), visual function-14 (VF-14) test, presence of dysphotopsia, and need for spectacles were evaluated at postoperative third month. Outcomes were compared between FLACS and SCS group. Results: The mean UDVA, UIVA, and UNVA were 0.05 ± 0.07, 0.08 ± 0.08, and 0.06 ± 0.07 logMAR, respectively. All patients achieved ⩾0.3 logMAR uncorrected visual acuity for all distances. UDVA was found significantly better in FLACS group ( p = 0.03). All eyes had ⩽1 D of subjective postoperative RA. Defocus curve had two peaks at 0 and −1.50 D. Spectacle independence was achieved in 88.7% of patients. Photopic and mesopic CS was within normal range in all patients. The mean VF-14 score was 98 ± 2. The mean IOL axis rotation was 2.1° ± 2.3°. Only one patient reported seeing disturbing halos. Conclusions: This trifocal toric IOL effectively reduced refractive astigmatism and provided excellent visual outcomes with high spectacle independence, patients’ satisfaction, and good rotational stability. FLACS might have an impact on optimal postoperative results.

PurposeTo evaluate the postoperative outcomes after implantation of a hydrophilic toric intraocular lens (tIOL) with a transitional conic toric surface in patients with astigmatism undergoing refractive lens exchange (RLE) or cataract surgery.MethodsIn this monocentric study, clinical outcomes following implantation of the hydrophilic Precizon toric IOL model 565 (Ophtec) were analysed. For intraoperative axis alignment, the Verion Image Guided System was used. Intended versus achieved refraction, IOL position, visual acuity outcomes and power vector analyses were evaluated 3 months postoperatively.ResultsForty-three eyes of 28 patients (40 eyes cataract, 3 eyes RLE) received a Precizon toric IOL with a cylindrical power between 1.0 and 7.5 D. Target refraction was emmetropia except for four eyes that had a myopic target. The median postoperative IOL rotation at slit lamp was 3° with a range from 0° to 16°. Uncorrected distance visual acuity (UDVA) increased from median 0.5 logMAR preoperatively to median 0.06 logMAR at 3 months postoperatively. Corrected distance visual acuity increased from 0.20 to −0.02 logMAR. Median preoperative subjective cylinder was 1.5 D and 3 months postoperatively 0.25 D.ConclusionPreoperative diagnostics, IOL selection and correct intraoperative positioning of tIOLs are essential for good outcomes and postoperative spectacle independence following cataract or RLE surgery. Visual acuities and rotational stability of the Precizon toric IOL showed very good outcomes and the subjective postoperative astigmatism could be reduced significantly.

Abstract Objectives To compare the efficacy of astigmatic correction between simultaneous femtosecond laser-assisted intrastromal arcuate keratotomy (AK) combined with femtosecond laser-assisted cataract surgery (FLACS) and toric intraocular lens (IOL) implantation during cataract surgery in moderate astigmatism. Design: Retrospective observational study, tertiary care medical center Methods We retrospectively reviewed medical records of patients who underwent astigmatic correction via femtosecond laser-assisted intrastromal AK (AK group; 27 eyes of 27 patients) with FLACS or toric IOL implantation (toric IOL group; 21 eyes of 21 patients). All patients had senile cataracts with corneal astigmatism ranging from + 1.00 to + 2.00 diopters (D) before cataract surgery. We measured visual acuity, intraocular pressure, automated keratometry, manifest refraction and topography preoperatively and at 1-day, 1-month, 3-month, and 6-month postoperatively. Results Refractive astigmatism was significantly decreased in both groups. The mean preoperative and 6-month postoperative refractive astigmatism were 1.85 ± 1.07 and 0.99 ± 0.51 D, respectively, in the AK group (P = 0.028), and 1.84 ± 0.81 and 0.68 ± 0.21 D, respectively, in the toric IOL group (P < 0.001). There was no significant difference in refractive astigmatism between the two groups at 6-month postoperatively (0.99 ± 0.51 vs 0.68 ± 0.21 D, P = 0.057). At 6-month postoperatively, parameters for vector analysis of refractive astigmatism showed no statistical difference between the two groups. Corneal astigmatism was significantly decreased in the AK group. There was significant difference in corneal astigmatism from topography and automated keratometer between the two groups at 6-month postoperatively (0.94 ± 0.40 vs 1.53 ± 0.46 D, P = 0.018 for topography and 0.98 ± 0.69 vs 1.37 ± 0.41 D, P = 0.032 for automated keratometer). Conclusions Femtosecond laser-assisted intrastromal AK in FLACS could be an effective procedure for reducing astigmatism as well as toric IOL implantation in cataract surgery.

Purpose: The long-term clinical outcomes of cataract surgery in patients with retinitis pigmentosa (RP) were evaluated. Methods: A retrospective analysis of medical records was performed for patients who were diagnosed with RP and underwent cataract surgery. Preoperative best-corrected visual acuity (BCVA) was compared with BCVA at 1 month postoperatively and at the final visit. The proportion of patients with cystoid macular edema development or aggravation after surgery was evaluated, as was the proportion of patients with intraocular lens subluxation/dislocation. For patients who underwent optical coherence tomography, factors associated with a BCVA of 0.5 or better at 1 month were analyzed. Results: In total, 133 eyes were included and the mean follow-up period was 58.7 months. The mean logarithm of minimal angle of resolution BCVA was 0.69 ± 0.65 at diagnosis. The BCVA was significantly improved to 0.51 ± 0.47 at 1 month postoperatively (p < 0.001). However, the BCVA at the final visit (0.70 ± 0.81) was similar to the baseline value (p = 1.000). Cystoid macular edema development or aggravation was noted in 8 eyes (6.0%) and intraocular lens subluxation/dislocation was noted in 4 eyes (3.0%). A subgroup analysis involving 108 eyes revealed that preoperative BCVA (p < 0.001) and ellipsoid zone status (p = 0.001) were associated with postoperative visual acuity. Conclusions: Short-term outcomes of cataract surgery in patients with RP were comparatively good. However, long-term visual deterioration was noted with disease progression. Preoperative BCVA and ellipsoid zone status are useful markers for predicting short-term visual outcomes.

AbstractThis study tried to compare the clinical outcomes of femtosecond laser-assisted astigmatic keratotomy (FSAK) and toric intraocular lens (IOL) implantation for astigmatism correction and identify factors affecting the efficacy of FSAK and toric IOL implantation in astigmatism correction. This retrospective case series comprised patients with corneal astigmatism ranging between 0.5 D and 4.5 D. Patients underwent FSAK or toric IOL implantation for cataract treatment and correction of astigmatism at the Samsung Medical Center, a tertiary surgical center, between April 2016 and December 2018. All patients underwent examination before and at three months after the surgery for comparative evaluation of refractive astigmatism, corneal high order aberrations and irregularity index. The astigmatism correction was analyzed by the Alpins method. Subgroup analysis of preoperative factors was based on the extent of target-induced astigmatism (TIA), the degree of astigmatism, and astigmatism classification based on topography. Thirty-one eyes underwent toric IOL implantation and 35 eyes underwent FSAK. The refractive astigmatism was significantly decreased in both toric IOL (P = 0.000) and FSAK group (P = 0.003). The correction index (CI) of refractive astigmatism was 0.84 ± 0.39 in the toric IOL and 0.71 ± 0.60 in the FSAK group. There was no difference between the two groups (P = 0.337). The CI of the FSAK group was significantly lower than in the toric IOL group when TIA was more than 1.5 D (P = 0.006), when correcting against-the-rule (P = 0.017), and limbus-to-limbus astigmatism (P = 0.008). In conclusion, toric IOL implantation is an effective and safe procedure for correcting preoperative astigmatism in cataract surgery in the short-term observation.

Abstract Background To evaluate the safety and efficacy of a new toric intraocular lens (IOL) with anchor-wing haptics. Methods The new toric IOL with anchor-wing haptics (NS60YT, NIDEK Co., Ltd.) was implanted in eligible patients with age-related cataracts with preoperative corneal astigmatism of 1.0 D or greater at a university hospital and two private hospitals in Japan. The following IOL cylinder powers were evaluated: 1.50 D (NS60YT3), 2.25 D (NS60YT4), 3.00 D (NS60YT5) and 4.50 D (NS60YT7). All patients were assessed out to 12 months postoperatively. The primary endpoint was visual acuity (VA) with spherical addition at 6 months postoperatively, and the primary analysis calculated the proportion of eyes with VA with spherical addition of 0.1 logMAR or better. The magnitude of rotation was compared to the intended axis of IOL implantation at each postoperative examination. Adverse events were evaluated for the safety analysis. Results This study enrolled 64 eyes of 53 patients. At 6 months postoperatively, for all IOL powers, VA with spherical addition of 0.1 logMAR or better was achieved in 90% [95% confidence interval (CI): 80–96] of eyes. The mean IOL rotation was 5.3 ± 4.3° at 12 months postoperatively. The mean magnitude of rotation ranged from 1.9° to 2.5° between each postoperative examination from 1 day to 12 months. There were no vision-threatening intraoperative or postoperative complications for the duration of the study. Conclusions The NS60YT IOL remained stable after implantation and was efficacious for treating 1.00 D or greater astigmatism in patients with senile cataracts. Trial registration This study was registered at ClinicalTrials.gov (NCT03242486) on August 8, 2017 - Retrospectively registered.

Abstract Background To compare the efficacies in astigmatic correction of simultaneous femtosecond laser-assisted cataract surgery (FLACS) with intrastromal arcuate keratotomy (ISAK) versus toric intraocular lens (IOL) implantation with conventional phacoemulsification in moderate astigmatism. Methods A retrospective chart review was conducted for patients who had undergone cataract surgery by one surgeon. We identified patients with preoperative corneal astigmatism from + 0.75 to + 2.00 diopters (D) who had undergone astigmatic correction with FLACS with ISAK or toric IOL implantation with conventional phacoemulsification. We measured the visual acuity, intraocular pressure, automated keratometer, manifest refraction, and topography preoperatively and 1-day, 1-month, 3-month, and 6-month postoperatively. The vector analysis of refractive astigmatism was performed. Results Of a total of 48 eyes of 48 patients, 27 eyes of 27 patients had FLACS with ISAK (AK group), and 21 eyes of 21 patients had conventional cataract surgery with toric IOL implantation (toric IOL group). Refractive astigmatism was significantly decreased in both groups. The mean preoperative and 6-month postoperative refractive astigmatism were 1.85 ± 1.07 and 0.99 ± 0.51 D, respectively, in the AK group (P = 0.028), and 1.84 ± 0.81 and 0.68 ± 0.21 D, respectively, in the toric IOL group (P < 0.001). There was no significant difference in refractive astigmatism between the two groups at 6-month postoperatively (0.99 ± 0.51 vs 0.68 ± 0.21 D, P = 0.057). At 6-month postoperatively, parameters for vector analysis of refractive astigmatism showed no statistical difference between the two groups. Corneal astigmatism was significantly decreased in the AK group. Corneal astigmatism from topography and the automated keratometer were significantly lower in the AK group 6-month postoperatively compared to toric IOL group (0.94 ± 0.40 vs. 1.53 ± 0.46 D, P = 0.018 for topography; and 0.98 ± 0.69 vs. 1.37 ± 0.41 D, P = 0.032 for the automated keratometer). Conclusions FLACS with ISAK could be an effective procedure for reducing astigmatism as well as toric IOL implantation in cataract surgery.

Background: Advancements in cataract surgery have necessitated the availability of intraocular lens preloaded delivery systems that can safely, effectively and predictably deliver IOLs in the eye. Preloaded delivery systems simplify and reduce procedural variability during surgery preparation. Objective: The objective of this study was to evaluate clinical acceptability, delivery characteristics and clinical outcomes in patients implanted with new generation hydrophobic acrylic Intraocular Lens with Preloaded delivery system. Methods: This was a single centre retrospective study. Total 41 patients were enrolled in the study to get at least 38 patients for evaluation. All patients were assessed on day1 and 1, 3 and 6 months after surgery. Results: EYECRYL-SERT showed ‘excellent’ ease of insertion and handling in all 41(100%) patients. Corrected Distance Visual Acuity (CDVA) improved from 0.74±0.58 logMAR during screening to 0.03±0.04 logMAR 6 months after surgery. The Corrected Intermediate Visual Acuity (CIVA) and Corrected Near Visual Acuity (CNVA) were 0.10±0.04 and 0.01±0.02 logMAR post 6 months surgery, respectively. The refractive spherical equivalence was -1.94±2.51 D during screening, which improved significantly (p=0.0018) to -0.21±0.47 D post 6 months surgery. The low and high contrast sensitivity was 0.06±0.06 and -0.05±0.06 logMAR after 6 months surgery, respectively. The endothelial cell loss was 5.67%, 7.22% and 9.75% at 1, 3, and 6 months after surgery, respectively, as compared to screening. None of the subjects reported any adverse event during the study period. Conclusion: The IOL delivery system (EYECRYL_SERT) provided desired delivery characteristics during cataract surgery and was effective in improving clinical outcomes in cataract patients.
