PURPOSE: Povidone-iodine (PI) is widely used to reduce the preoperative conjunctival bacterial load. This study aimed to evaluate the employment of PI 10% in an attempt to sterilize the ocular surface prior to cataract surgery, and to show that PI could be left in contact for 3 minutes. The viability of this exposure time in clinical practice, associated adverse events, and visual outcomes were documented. METHODS: In this prospective cohort study, phacoemulsification cataract surgery was performed in 604 patients by a single surgeon...

PURPOSE: Ubiquitin is involved in cell proliferation and differentiation, and the objective of this study is to investigate the potential of dominant negative Ubiquitin (Ub) with a lysine to tryptophan mutation at the 6 position (K6W) through an adenoviral expression vector in the prevention of posterior capsule opacification (PCO) in a rabbit PCO model. METHODS: Recombinant dominant negative K6W-Ub adenovirus (RAd-K6W-Ub) with green fluorescent protein (RAd-K6W-Ub/GFP) and RAd-GFP viruses (control) were generated with QBI-HEK 293A cells...

We report a case of bilateral cataract surgery performed in a 21-year-old western lowland gorilla. Phacoemulsification with intraocular lens insertion was performed using standard human surgical equipment. Visual function significantly improved. She subsequently mated and gave birth. Ultimately, cataract surgery enabled the birth of a baby gorilla.

Soosan Jacob, Smita Narasimhan, Amar Agarwal, Cosimo Mazzotta, Miguel Rechichi, Athiya Agarwal
We describe a technique to prevent late intraocular lens (IOL) subluxation and dislocation that can be associated with progressive zonulopathy. Supracapsular glued IOL fixation is done to retain an intact anterior hyaloid face and avoid vitreous disturbance while providing stable long-term IOL fixation. Phacoemulsification is followed by glued IOL implantation above intact anterior and posterior capsules. Sclerotomies are created ab interno in a supracapsular plane under diametrically opposite lamellar scleral flaps without entering the vitreous cavity...

PURPOSE OF REVIEW: Descemet membrane endothelial keratoplasty (DMEK) has become a first-line treatment in corneal endothelial diseases because of its exceptional clinical outcomes and low complication rates. Because of its improved refractive predictability, DMEK is now also considered for managing cases with endothelial decompensation following previous refractive procedures, or in combination with those. This article reviews the clinical outcomes in these cases and discusses the possibility of refractive interventions following DMEK...
