Premium Intraocular Lens Selection in Patients With Glaucoma: A Clinical Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Glaucoma frequently coexists with cataract, but glaucomatous functional loss, ocular‐surface disease, anatomical abnormalities, and treatment‐related refractive variability may reduce tolerance of premium intraocular lenses. This narrative review critically appraises evidence relevant to lens selection in glaucoma. Central visual‐field status,

Hit the Ground Running: Early Eyesi Performance Characterises Learning Trajectories in Cataract Surgical Simulation

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background While cataract surgical simulation is known to improve trainee performance, the mechanisms underpinning individual variation in learning trajectories remain poorly understood. This study aimed to investigate the associations between early performance on the Eyesi surgical simulator and subsequent learning efficiency, proficiency and

Phakic Pattern Pseudoexfoliation Material Accumulation on Intraocular Lens Surface

, 2014
Pseudophakic pseudoexfoliation is the accumulation of pseudoexfoliation material on the intraocular lens. Most of the cases have showed scattered flecks of pseudoexfoliation material on the surface of the intraocular lens.

The effectiveness of early lens extraction with intraocular lens implantation for the treatment of primary angle-closure glaucoma (EAGLE) : study protocol for a randomized controlled trial [PDF]

, 2011
Glaucoma is the leading cause of irreversible blindness. Although primary open-angle glaucoma is more common, primary angle-closure glaucoma (PACG) is more likely to result in irreversible blindness.

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

Veterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.
