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.

A randomised controlled trial on cross‐linking protocols for the treatment of progressive keratoconus using isoosmolar and hypoosmolar riboflavin with the addition of sterile water in thin corneae

Acta Ophthalmologica, Volume 104, Issue 1, Page e63-e74, February 2026.
Abstract Purpose To present the outcomes of a randomised clinical trial for the treatment of progressive keratoconus using different kinds of riboflavin and the addition of sterile water in thin corneae. Methods A randomised study using epithelium‐off corneal cross‐linking (CXL) with continuous UVA irradiance 9 mW/cm2 for 10 min (total fluence 5.4 J ...

Evaluation of the Effect of Topical Vitamin A Eye Ointment on Pain Reduction and Accelerated Healing of Corneal Defect After Photorefractive Keratectomy: A Prospective Randomized Controlled Study

Health Science Reports, Volume 8, Issue 12, December 2025.
ABSTRACT Background and Aims Photorefractive keratectomy (PRK) is commonly used for refractive errors but is associated with postoperative pain and delayed epithelial healing. Vitamin A has been shown to support epithelial regeneration and corneal wound healing.

Corneal densitometry changes in keratoconus patients after intrastromal corneal ring segments implantation

Journal of the Egyptian Ophthalmological Society
Background Keratoconus (KC) is an ectatic corneal disorder characterized by progressive corneal thinning with myopic astigmatism. Intrastromal corneal ring segments (ICRS) have been broadly selected as a surgical intervention for KC correction to delay ...

Effects of customized corneal cross‐linking on higher‐order aberrations in progressive keratoconus and low‐grade myopia

Acta Ophthalmologica, Volume 103, Issue 8, Page 966-973, December 2025.
Abstract Objective To evaluate the effects of customized corneal collagen cross‐linking (CXL) on higher‐order aberrations (HOAs) in keratoconus (KC): vertical coma (VC), horizontal coma (HC), spherical aberration (SA), trefoil (TF) and astigmatism, compared with the same effects in healthy eyes undergoing CXL for low‐grade myopia.
