Evaluation of visual outcomes with toric intraocular lens implantation using digital marker during cataract surgery.

Objectives: To assess the visual improvement and mean residual astigmatism in patients who underwent cataract surgery with toric intraocular lens.

Methods: The retrospective, observational study was conducted at the Department of Ophthalmology, Aga Khan University Hospital, Karachi, and comprised data from January 1, 2018, to December 31, 2020, related to adult patients who had regular astigmatism of at least 0.75D and underwent cataract surgery with toric intraocular lens implantation using a digital marker.

Efficacy and safety of intravitreal injection of triamcinolone-moxifloxacin after cataract surgery in a low to middle income country - a one-year audit.

Objective: To evaluate the safety and efficacy of intravitreal injection of triamcinolone and moxifloxacin regime administered immediately following cataract surgery.

Methods: The retrospective study was conducted from January to June 2021 at a tertiary care referral centre in Karachi and comprised record of all patients who underwent dropless cataract surgery from April 2018 to June 2019. Data included slit lamp examination, dilated fundal exam, uncorrected visual acuity, best corrected visual acuity, and intraocular pressure.

YAG capsulotomy rates between two types of trifocal intraocular lenses.

Objectives: To evaluate YAG capsulotomy rates following implantation of two types of trifocal intraocular lenses (IOLs).

Methods: In this retrospective cohort study consecutive patients who underwent cataract surgery with a trifocal IOL from 1st May 2017 to 30th October 2019 at Aga Khan University Hospital, Karachi were included. Eyes which either had an AT Lisa Tri or Alcon PanOptix IOL implant were included.

Post-operative endophthalmitis after immediate sequential bilateral cataract Surgery: A retrospective study from Pakistan.

Objective: To assess the frequency of post-operative complications after immediate sequential bilateral cataract surgery.

Methods: The retrospective study was conducted at the department of surgery/section of ophthalmology, Aga Khan University Hospital, Karachi, and comprised data of patients who underwent immediate sequential bilateral cataract surgery between January 1, 2009, and December 31, 2018. A structured proforma was used to collect data.

The role of simulators in improving vitreoretinal surgery training - A systematic review.

Objective: To conduct an appraisal of current evidence regarding the effectiveness of EyeSi®-based training of vitreoretinal surgery.

Methods: The systematic review was conducted in July 2020, and comprised literature search on Cochrane Library, PubMed and Embase for articles regarding simulation training in vitreoretinal surgery. The shortlisted articles were subjected to qualitative analysis.

Choroidal neovascularization secondary to Best vitelliform macular dystrophy detected by optical coherence tomography angiography.

Best vitelliform macular dystrophy (VMD) is a hereditary condition that causes childhood-onset macular dystrophy. In rare cases, VMD is accompanied by formation of a choroidal neovascular membrane (CNVM). We report a case of CNVM secondary to Best VMD in a 10-year-old boy that was detected using optical coherence tomography angiography, a new noninvasive diagnostic modality that detects motion contrast in repeated B-scans to identify blood flow within vessels.

Topiramate induced sudden loss of vision.

The case of a 20 year old female presenting with overnight acute loss of vision is reported. The patient was recently started on topiramate (Hitop) for her recurrent migraine and developed sudden loss of vision due to acute myopia. Topiramate was discontinued and the patient's vision returned to normal.

Correlation between corneal and scleral thickness in glaucoma.

Purpose: To assess the correlation between central corneal thickness (CCT) and anterior scleral thickness (ST) in patients of primary open-angle glaucoma (POAG), normal tension glaucoma (NTG), and ocular hypertension (OHT).

Patients And Methods: Consecutive patients with OHT, POAG, NTG, and normal individuals were recruited. CCT was measured by ultrasonic pachymetry, whereas ST was measured using ultrasonic biomicroscopy at the temporal quadrant, 2 mm posterior to the scleral spur.
