Purpose: To compare the parameters of capsulorrhexis and intraocular lens decentration after femtosecond laser capsulotomy and manual continuous curvilinear capsulorrhexis in high myopic patients with cataracts.Methods: This is a prospective consecutive non-randomized comparative cohort study. Selected patients with axial length > 26.0 mm were divided into femtosecond laser capsulotomy (FS) group and manual continuous curvilinear capsulorrhexis (CCC) group. Five experienced phacoemulsification surgeons conducted all surgeries. Intraoperative complications and post-operative anterior segment photography were recorded. Intraocular lens decentration, area of capsulorrhexis, circularity, and capsule overlap were measured at 1 week, 1 month, and 2 years after surgery. Between group differences of parameters were determined with independent-sample t-test or the Mann–Whitney U-test, analysis of variance test, Pearson chi-square test, and Spearman rank correlation test.Results: The study included 142 eyes (108 patients), 68 eyes in the FS group, and 74 eyes in the CCC group. At 1 week, 1 month, and 2 years after surgery, the area of capsulorrhexis in the CCC group was significantly larger than in the FS group (P < 0.05), while no significant difference was noted in circularity values. The complete overlap ratio in the FS group was significantly higher than that in the CCC group (P < 0.05) at each measured timepoint. Significant correlations were noted between the anterior chamber depth and the area of capsulorrhexis in the CCC group (R = 0.25, P = 0.04), but did not correlate in the FS group (P > 0.05). In patients with an anterior chamber depth >3 mm, the capsule-intraocular lens (IOL) overlap of the CCC group was less than that of the FS group at all measured timepoints after surgery (P < 0.05). Meanwhile, the IOL decentration in the CCC group was significantly greater than that of the FS group in those patients at 2 years after surgery (P < 0.05).Conclusion: In high myopic patients with cataracts, with anterior chamber depth more than 3 mm, femtosecond laser capsulotomy can achieve better capsulorrhexis sizing and centering. Due to more precise capsulotomy and a better capsule-IOL overlap in the FS group, femtosecond laser capsulotomy resulted in better long-term centration of the IOL.

Purpose:  To document the complications of Manual suture-less cataract surgery in eyes with pseudo-exfoliation. Study Design:  Interventional case series. Place and Duration of Study:  Naseer memorial hospital, Dadyal, Azad Jammu Kashmir, from 4 July 2017 to 3 July 2019. Methods:  One hundred and fifty patients with pseudo-exfoliation (PEX) and cataract were selected by convenient sampling. Patients with systemic diseases, history of trauma, intraocular pressure ≥15 mm Hg on Applanation tonometry and any other associated ocular disease for example retinal detachment or retinal disease, previous history of glaucoma or narrow/closed angle on Gonioscopy were excluded from the study. Dark brown cataracts were also excluded. Pseudo-exfoliation was diagnosed on slit lamp on the basis of presence of dandruff like material on the pupil and the anterior lens capsule. The patients underwent manual suture less cataract surgery under local anesthesia Intraoperative and post-operative complications were noted. first day postoperatively. The collected data and analyzed using statistical package for social sciences (SPSS) version 21 for analysis. Results:  The study group consisted of 64% males and 36% females with mean age of 65 ± 15.32 years. The most common difficulty encountered was poor pupil dilatation in 37.3% cases followed by Zonular dehiscence in 7.3%. On the first post-operative day, the most common complication was intraocular lens decentration in 2.6% of the cases. Conclusion:  Pupils of patients with pseudo-exfoliation dilate poorly and makes surgery difficult. With good pupillary dilatation, careful capsulorhexis and minimal stress on the zonules, MSCS can be safely performed in eyes with cataract and PEX. Key Words:  Pseudo-exfoliation, Cataract, Pupil.

Purpose: The aim of this article is to describe a novel surgical technique for sutureless scleral fixation of an intraocular lens using the newly developed FIL SSF Carlevale IOL (Soleko, Italy). Methods: Four eyes of four patients with poor capsular support were recruited to our study, three resulting from intraocular lens subluxation and one case resulting from traumatic cataract. A novel sutureless sclera-fixated intraocular lens was implanted into the posterior chamber of each eye with sclerocorneal plugs fixating the lens to the wall of the eye. Results: Mean age of patients was 52 ± 16 years, ranging from 35 to 70 years. Mean follow-up was 6.50 ± 1.29 months (range: 5–7 months). Mean preoperative best-corrected visual acuity was 0.50 ± 0.33 logMAR (range: 1–0.3 logMAR). Postoperative best-corrected visual acuity improved to 0.08 ± 0.08 logMAR (range: 0.2–0 logMAR). There was no significant change in the mean intraocular pressure and there were no postoperative complications, such as iatrogenic distortion or breakage of the intraocular lens haptic, intraocular lens decentration, endophthalmitis, or retinal detachment. Discussion: To the best of our knowledge, this is the first report of outcomes using the novel sutureless sclera-fixated FIL SSF Carlevale IOL. This new surgical technique offers a simplified and effective approach for sutureless scleral intraocular lens fixation with good refractive outcomes.
