Corneal endothelial cell loss and intraocular pressure following phacoemulsification using a new viscous-cohesive ophthalmic viscosurgical device.

Purpose: To compare results of two ophthalmic viscosurgical devices (OVDs)-Viscoat (a dispersive OVD, Alcon) and FR-Pro (a viscous-cohesive OVD, Rayner), in phacoemulsification surgery.

Methods: A prospective randomized controlled study. Patients undergoing phacoemulsification were randomly assigned to receive one of the two OVDs.

Central retinal vein occlusion in a young healthy COVID-19 patient: A case report.

Purpose: We detail a unique case of a healthy 33-year-old suspected COVID-19 patient who presented with unilateral Central Retinal Vein Occlusion, possibly as a complication of COVID-19.

Observations: A 33-year-old healthy male was referred to the emergency department due to blurred vision in his left eye for the past month, accompanied by flashes of light without any accompanying neurological symptoms. The patient reported a three-week period of fatigue, dry cough, and shortness of breath ended about 2 weeks prior to the ocular symptoms.

The accuracy of the double-K adjustment for third-generation intraocular lens calculation formulas in previous keratorefractive surgery eyes.

Purpose: To evaluate the effect of the double-K (DK) modification on third-generation formulas.

Methods: Thirty-eight previously myopic and 24 previously hyperopic eyes that underwent phacoemulsification with intraocular lens (IOL) insertion after Laser in situ keratomileusis (LASIK) were evaluated. Pre-LASIK refraction and keratometry, post-LASIK topography, axial length (AL), IOL type and power, and 1-month postphacoemulsification refraction were recorded spherical equivalent after phacoemulsification (SE(postphaco)).

Staphylolysin is an effective therapeutic agent for Staphylococcus aureus experimental keratitis.

Background: Therapy of S. aureus keratitis is increasingly challenging due to emerging resistant strains. Staphylolysin (LasA protease) is a staphylolytic endopeptidase secreted by Pseudomonas aeruginosa.
