Abstract Cataract is the leading cause of blindness worldwide, and advanced cataract procedures such as femtosecond laser-assisted cataract surgery are widely available. Corneal refractive surgery is one of the most common procedures for the correction of refractive errors. The aim of this report is to determine if FLACS after CRS is more effective and safe than conventional PCs. Participants from a previous CRS history were not included in this study, whether FLACS or conventional PCS were used. A total of 102 patients with age-related cataract disease were enrolled. In FLACS, the reduction of refractive astigmatism was higher. FLACS was found to be safe in patients with a previous history of CRS in terms of vision and refractive outcomes, as well as free of adverse effects. FLACS' competitive edge in postoperative ORA may be greater than conventional PCs, with the reduction of refractive astigmatism and ORA.

Methods: This retrospective review looked at the postoperative results of patients undergoing fluorescenction with toric intraocular lens implantation in FS-AK and patients undergoing standard phacoemulsification with toric intraocular lens implantation. Results: The FL-AK group contained 41 eyes with preoperative keratometric astigmatism of u22121. 64 diopters u00b1 0. 42, and the toric IOL group contained 53 eyes with preoperative keratometric astigmatism of u22122. 29 D u00b1 0. 91 D. Both FLACS with FS-AK and standard phacoemulsification with toric IOL implantation are safe and efficient tools for astigmatism correction at the time of cataract surgery. At a 6-month follow-up, Standard phacoemulsification with toric IOL implantation achieves a better visual result than combined FLACS and FS-AK.

This review sought to compare the clinical effects of the introduction of several multifocal intraocular lenses and the prediction of two intraocular lens power calculation formulas for eyes that underwent previous corneal refractive surgery. The Barrett True-K formulation had a narrower range of PEs and lower MedAE than Shammas-PL, which was for all groups. When compared to those with greater predictive accuracy, eyes of lower predictive accuracy revealed poor uncorrected distance visual acuity as a result of myopic refractive error and target refraction. In patients undergoing mIOL implantation with prior corneal refractive surgery, a targeting emmetropia using the Barrett True-K is recommended.

Abstract Backgrounduff1aTo determine the effects of anterior capsular opening size on deviation from predicted refraction and the optimal position of the intraocular lens in cataract surgery. Conclusions: The capsulorrhexis' shape influences postoperative refractive results and the optimal position of the intraocular lens in cataract surgery, as well as the consistent position of the intraocular lens in cataract surgery, and the use of the intraocular lens in cataract surgery, as well as cataract surgery's optimal position, and the optimal location of the intraocular lens, and plate haptic intraocular lenses have improved refractive stability, more consistent than C-loop haptic intraocular lenses.

Background information:uff1aAbout a Detailed study was done on the effect of anterior capsular opening size on deviation from predicted refraction and the correct position of an intraocular lens in cataract surgery. The deviation from predicted refraction and all of the capsulorrhexis parameters in the 509 million IOL group was not correlative at 1 week, however, in the Tecnis IOL group, although the change from predicted refraction and all of the capsulorrhexis parameters were not correlative, and the capsulorrhexis parameters were not correlative, but there are no other capsulorrhexis parameters was not corre capsulorrhexis refraction and all of the capsulorrhexis parameters were not correfraction parameters were not correfraction parameters were not correfract capsulorrhexis section proxi tecno s predictorrhexis capsulorrhexis calcus rhexis determination graftrhexis proxi chon mo adherence to coli rhexis aedophylogistic t calculologized aedo granultin the pharmacand tel.

Purpose: To determine the refractive results of combined cataract surgery and vitrectomy, as well as cataract surgery alone. Methods: This retrospective chart review found two groups 103 eyes 101 patients who underwent cataract surgery with posterior chamber intraocular lens PCIOL placement by a single cataract surgeon and vitrectomy by a single vitreoretinal surgeon in the same surgical setting as the same surgeon in 109 eyes 84 patients. There was no difference between the two groups in SIA refractive results P = 0. 509. The use of intraoperative gas for retina tamponade did not have a major effect on postoperative refractive outcomes. Detailed analysis and Conclusion: Combination cataract surgery and vitrectomy results provide excellent refractive results equal to cataract surgery alone, allowing each procedure to be carried out by separate anterior and posterior segment surgeons.
