Background: Iris root is the thinnest and weakest portion of iris stroma. It can detach easily due to blunt trauma or accidental engagement during intraocular surgery resulting in glare, photophobia monocular diplopia. Multiple techniques described for iridodialysis repair such as hang back technique, stroke dock technique sewing machine are technically challenging. Purpose: To describe an simplified approach using 9-0 prolene suture. Synopsis: We demonstrate animation better understanding....

A 55-year-old male presented to us with defective vision in the left eye (LE) for 6 months, associated a history of blunt trauma. On examination, best corrected visual acuity (BCVA) 1/60 and cataract nuclear sclerosis grade 2 along anterior lens capsule (ALC) fibrosis was noted [Fig. 1a]. The patient advised femtosecond laser-assisted surgery (FLACS) (Alcon-LenSx Lasers Inc).Figure 1: (a) Slit lamp photograph using diffuse illumination eye. Nuclear traumatic thick were noted. (b)...

Purpose: To evaluate higher order aberrations (HOA) in different types of posterior capsule opacification (PCO) and analyze its changes following Nd:YAG laser capsulotomy (LPC). Settings: Tertiary care ophthalmic hospital. Design: Prospective, comparative, observational study. Methods: One hundred ninety-three pseudophakic eyes with PCO were evaluated over 3 months. was classified into pearly, fibrous, mixed types. Their uncorrected visual acuity (UCVA), corrected distance (CDVA),...

Purpose: The purpose of this study was to evaluate trainee performance across six modules a virtual reality (VR) simulator. Methods: A retrospective observational conducted on 10 manual small-incision cataract surgery (MSICS) trainees who practiced an MSICS VR simulator for one month. They were assessed in major steps which included scleral groove, tunnel dissection, keratome entry, capsulorhexis, nucleus delivery, and intraocular lens (IOL) insertion under trainer’s supervision. information...

Aim: The aim is to study the correlation of macular thickness and sensitivity in type 2 diabetes mellitus patients. Materials Methods: A cross-sectional comparative was done on 77 eyes with diabetic retinopathy. Patients were divided into three groups as follows: Group 1 – Diabetic retinopathy without maculopathy, maculopathy clinically significant edema (CSME), 3 CSME. Microperimetry used assess sensitivity, optical coherence tomography (OCT) measure retinal thickness. Comparison between...

Background: Cataract surgeries are challenging in colobomatous eyes as they associated with features such microphthalmia, microcornea, zonular deficit, etc. These factors predispose to capsulorhexis extension, posterior capsular rent, dialysis and result unfavourable visual outcomes. The most critical step of cataract surgery cases is the chances extension high area. In presence pre-existing dehiscence, nucleus management becomes more advanced cataracts. Purpose: To illustrate efficient...
