Purpose: To evaluate higher order aberrations (HOA) in different types of posterior capsule opacification (PCO) and analyze its changes following Nd:YAG laser posterior capsulotomy (LPC).
Settings: Tertiary care ophthalmic hospital.
Design: Prospective, comparative, observational study.
Purpose: To assess the learning curve of MSICS in three different groups of trainees with varying prior MSICS experience. To evaluate the effectiveness of ICO OSCAR for objective assessment of surgical skill transfer.
Methods: Ninety-five MSICS trainees were divided into three groups as 1st year resident, fellow and external trainee.
Purpose: To determine the incidence, risk factors and clinical outcomes in patients with nucleus drop (ND) following phacoemulsification surgery at a tertiary care ophthalmic institute.
Methods: Medical records of patients with ND during phacoemulsification between January'2019 and December'2022 were reviewed retrospectively. Incidence of ND was calculated overall, and according to surgical expertise levels and surgical steps.
Purpose: To compare the slit-lamp method and wavefront aberrometry method based on outcomes of toric realignment surgeries.
Settings: Tertiary care ophthalmic hospital.
Design: Retrospective study.
Article Synopsis
- This study evaluated the outcomes of manual small incision cataract surgery (MSICS) on 286 patients who had cataracts complicated by corneal opacity at a tertiary care eye hospital.
- It found that nebular corneal opacity was the most common type, often resulting from trauma or infection, and the intra-operative complication rate was 4.89%.
- The surgery significantly improved patients' vision, with median logMAR vision enhancing from 1.08 pre-operatively to 0.3 post-operatively, indicating that MSICS is an effective alternative for these cases.
Purpose: The purpose of this study was to evaluate trainee performance across six modules of a virtual reality (VR) simulator.
Methods: A retrospective observational study was conducted on 10 manual small-incision cataract surgery (MSICS) trainees who practiced cataract surgery on an MSICS VR simulator for one month. They were assessed in six major steps which included scleral groove, tunnel dissection, keratome entry, capsulorhexis, nucleus delivery, and intraocular lens (IOL) insertion under a trainer's supervision.
Purpose: To report the outcomes of cataract surgery in patients with Human Immunodeficiency Virus (HIV) infection. Setting Tertiary care ophthalmic hospital DESIGN: Retrospective study METHODS: This study included all eyes of patients with known HIV infection undergoing cataract surgery with a minimum follow-up of 6 months between January 2017 and December 2020. Patients who underwent combined surgeries and pediatric patients were excluded from analysis.

Methods: All consecutive patients with PPC who underwent phacoemulsification during the study period from 2016 to 2019 were included and sub-grouped based on the morphological characteristics according to Daljit Singh's classification. Intraoperative complications such as posterior capsular rupture (PCR), vitreous loss, nucleus drop, and Postoperative best-corrected visual acuity (BCVA) at day 1 and day 30 were documented.
Purpose: To evaluate a system that objectively assesses the risk of cataract surgery complications performed with phacoemulsification and manual small incision cataract surgery (MSICS) techniques.
Methods: The study was a retrospective comparative interventional case series. Electronic medical records of consecutive eyes that underwent cataract surgery from January 2019 to December 2019 were evaluated.
Article Synopsis
- The study aimed to compare the safety and effectiveness of the Active Sentry handpiece versus the Ozil handpiece for cataract surgery using the Centurion phacoemulsification system in a South Indian eye center.
- A total of 204 patients with uncomplicated cataracts were randomly assigned to undergo surgery with either handpiece, evaluating factors like patient pain, surgeon comfort, energy use, and postoperative outcomes.
- Results showed no significant differences in patient pain, visual acuity, or corneal edema between the two groups, but surgeons preferred the Ozil handpiece for certain tasks; however, the Active Sentry operated at lower intraocular pressure levels, indicating it was equally safe and effective.
Purpose: The aim of this study was to compare the predictability and accuracy of the American Society of Cataract and Refractive Surgery (ASCRS) online calculator with the Haigis-L formula for intraocular lens (IOL) power calculation in post myopic laser-assisted in-situ keratomileuses (LASIK) eyes undergoing cataract surgery and also to analyze the postoperative refractive outcome among the ASCRS average, maximum and minimum values.
Methods: A retrospective study was conducted on post myopic LASIK eyes which underwent cataract surgery between June 2017 and December 2019. IOL power was calculated using both Haigis-L & ASCRS methods.
Purpose: To report clinical outcomes of retropupillary iris-suture-fixated rigid intraocular lens (IFIOL) SETTING: Tertiary care ophthalmic hospital DESIGN: Retrospective study METHODS: This study included all eyes undergoing IFIOL with a minimum follow-up of 6 months between April 2017 and January 2019. Patients with preexisting anterior or posterior segment pathologies causing defective vision, uveitis or history of previous intraocular surgeries with exception of cataract surgery were excluded from the study. Data were retrieved from electronic medical records, and we documented demographics, history, position of cataractous lens or IOL, primary/secondary surgery and its complications.
