Endothelial Cell Loss, Cumulative Dissipated Energy, and Surgically Induced Astigmatism in Sutureless Scleral Tunnel Phaco-Assisted Cataract Extraction in Advanced Cataracts.

Purpose: To evaluate sutureless scleral tunnel phaco-assisted cataract extraction in regards to the cumulative dissipated energy (CDE) used, the resulting endothelial cell loss (ECL), and the surgically induced astigmatism (SIA) in advanced cataracts.

Methods: A prospective interventional uncontrolled case series was performed. Patients with advanced cataracts according to the Lens Opacities Classification System III (LOCS III) had sutureless scleral tunnel phaco-assisted cataract extraction.

Trocar-assisted flanged transconjunctival intrascleral sutureless intraocular lens fixation.

Purpose: To study the safety and efficacy of 25-gauge trocar-assisted flanged intrascleral sutureless IOL fixation in patients with insufficient posterior capsular support.

Methods: Five aphakic eyes with capsular insufficiency were included in this prospective interventional case series study, at Dar El Oyoun Hospital, Cairo, Egypt. Twenty five-gauge trocar-assisted flanged intrascleral sutureless technique was used for IOL fixation, in which retinal microforceps were used to capture and externalize both haptics through a scleral tunnel.

Short-term effect of weight loss after bariatric surgery on IOP, RNFL thickness, and the optic nerve head blood flow measured by OCTA.

Purpose: To study the influence of weight reduction after bariatric surgery on the intraocular pressure (IOP), retinal nerve fiber layer (RNFL) thickness, and blood flow of optic nerve head by optical coherence tomography angiography (OCTA).

Methods: This prospective observational cohort study included 60 obese patients. Body mass index (BMI), IOP, RNFL, and ganglion cell complex (GCC) thickness, rim area, and radial peripapillary capillary (RPC) vessel density were assessed before and 3 months after bariatric surgery.

Comparison between different tonometers following intrastromal corneal ring segments implantation.

Purpose: To compare different intraocular pressure (IOP) readings in corneas with intrastromal corneal ring segments (ICRS) taken by three different tonometers; Goldmann applanation tonometry (GAT), air puff tonometer, and ocular response analyzer (ORA) corneal-compensated IOP (ORA-IOPcc) and determine the relation of these measurements to different corneal parameters taken by Pentacam.

Methods: An observational cross-sectional analytic study included patients who underwent ICRS keraring implantation at 3 months. In each eye, the two rings were placed using the femtosecond laser assisted technique 5.

Seven-day storage of pneumatically dissected Descemet's endothelial grafts with and without Dua's layer.

Purpose: To evaluate the efficacy of big-bubble (BB) technique in separating Dua's layer together with the Descemet's membrane endothelial (DE) graft and the effect of 7-day storage of the prepared tissues on the endothelial cells.

Method: This is an experimental study in which 21 human corneo-scleral tissues unsuitable for transplantation were used. Grafts were mounted on artificial chamber; epithelial side-up with BB technique was used to detach the DE graft.

Effect of lens status on intraocular pressure in siliconized eyes.

Purpose: To evaluate the effect of lens status on intraocular pressure (IOP) in siliconized eyes and also on the emulsification of silicone oil.

Patients And Methods: A total of 31 eyes of 31 patients with retinal detachment were operated on with pars plana vitrectomy and silicone oil injection: 16 phakic (Group A) and 15 pseudophakic (Group B). During the 6-month follow-up period, IOP was measured: 1 day postoperative, then at 1 week, 1 month, 2 months, 3 months, and 6 months postoperative.

Torsional ultrasound mode versus combined torsional and conventional ultrasound mode phacoemulsification for eyes with hard cataract.

Purpose: To compare torsional versus combined torsional and conventional ultrasound modes in hard cataract surgery regarding ultrasound energy and time and effect on corneal endothelium.

Settings: Kasr El Aini hospital, Cairo University, and International Eye Hospital, Cairo, Egypt.

Methodology: Ninety-eight eyes of 63 patients were enrolled in this prospective comparative randomized masked clinical study.

Low-level versus high-level placement of gold plates in the upper eyelid in patients with facial palsy.

Background: Lagophthalmos is a condition that results from facial paralysis causing functional as well as esthetic problems. This condition can be treated by a range of techniques, including tarsorrhaphy, facial slings, and canthopexies. Gold plates provide a solution for temporary or permanent lagophthalmos resulting from facial paralysis.
