Cataract Surgery in the Small Adult Eye: A Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Modern cataract surgery continues to advance, yet intraocular lens (IOL) based surgery in the small adult eye remains challenging. Thorough preoperative assessment and surgical preparation optimise postoperative outcomes in these cases. Advances in IOL power calculation, including artificial intelligence‐driven formulas, improve accuracy ...

Deciphering the performance of different surface models for corneal topography

Ophthalmic and Physiological Optics, EarlyView.
Abstract Purpose To study the performance of different corneal surface models to be used for ray tracing. Models based on geometric surfaces and polynomial fits were compared and the differences discussed. Methods For this simulation study, five characteristic generic surface configurations were generated: (A) perfect biconic, (B) decentred biconic ...

Aetiology of keratoconus. [PDF]

British Journal of Ophthalmology, 1976
Keratoconus has a common association with atopic conditions. Most keratoconus patients rub their eyes excessively. Eye-rubbing is considered the dominant aetiological factor in two-thirds of patients with keratoconus who progress to contact lens wear. A classification of keratoconus based on the dominant aetiological factors is proposed. No significant

Costello Syndrome and Ophthalmologic Issues: Unveiling the Unseen

American Journal of Medical Genetics Part A, Volume 197, Issue 7, July 2025.
ABSTRACT Costello syndrome (CS) is an ultra‐rare condition belonging to the RASopathies, a group of disorders characterized by aberrant RAS/MAPK pathway signaling, which is involved in ocular development and in some eye pathologies. However, only a few studies assessing the ophthalmic features of individuals with CS are available.
