An 84-year-old monocular woman was referred to our institution for the management of corneal decompensation in her only eye, the right eye. The patient had secondary implantation of an anterior chamber iris-claw intraocular lens (IOL) for IOL dislocation in the setting of pseudoexfoliation syndrome 2 years before presentation. Descemet-stripping automated endothelial keratoplasty (DSAEK) combined with retropupillary repositioning of the iris-claw IOL using a flipping technique was performed for the treatment of corneal edema. No intraoperative or postoperative complications occurred. Six months postoperatively, the corneal graft was attached and clear and the retropupillary iris-claw IOL was well positioned. The uncorrected distance visual acuity and corrected distance visual acuity improved from counting fingers preoperatively to 20/200 and 20/63, respectively, after surgery. Combined DSAEK and retropupillary refixation of a prepupillary iris-claw IOL using the flipping technique was a safe technique in this patient with corneal decompensation.

Introduction The Sri Lankan economic crisis that began in 2019 led to the suspension of cataract services in many districts. Although humanitarian missions were quick to supply materials, there was a lack of scientific evidence to predict the required intraocular lens power for patients with cataracts. This study aimed to assess the average lens power among patients from Trincomalee district, Sri Lanka, based on sex and age groups.

In cataract surgery, post-surgical stability of the intraocular lens plays a major role. This study aims to explore how the size and decentration of the capsulorhexis affect intraocular lens decentration and tilt by using numerical methods. Finite element models included zonules, ciliary body, capsular bag, and an IOL with two open-loop haptics were built.

Purpose: This study compares the functional outcomes of correction using two different types of aberrational extended depth-of-focus (EDOF) intraocular lenses (IOLs).
Material And Methods: The study was conducted in two standardized groups (20 patients, 20 eyes in each group). Patients in group 1 were implanted EDOF IOL I, in group 2 - EDOF IOL II.

Preparation for cataract surgery in patients with keratoconus (KC) is associated with particular challenges: calculating the optical power of the intraocular lens (IOL), selecting the appropriate IOL model, and considering additional interventions aimed at stabilizing KC and reducing irregular astigmatism. This article presents a fundamentally new approach to combined treatment of KC with cataract, consisting of two stages: first, performing bandage therapeutic-optical keratoplasty (BTOK), followed by cataract phacoemulsification as the second stage.

Purepose: The intraoperative femtosecond laser time, Cumulative Dissipated Energy (CDE), Effective Phacoemulsification time (EPT), and intraoperative fluid perfusion volume were compared under different model fragmentation modes using Catalys femtosecond laser system.
Methods: This was a single-center, prospective, randomized controlled study. A total of 120 eyes who underwent femtosecond laser-assisted cataract phacoemulsification combined with intraocular lens implantation in Xiamen Eye Center affiliated to Xiamen University from September 2022 to March 2023 were randomly divided into 4 groups to undergo pre-nucleus splitting in different ways: Group 1: six-split, Group 2: eight-split, Group 3: six-split + gridded softening, and Group 4: eight-split + gridded softening.
