Corneal higher order aberrations by Sirius topography and their relation to different refractive errors.

Purpose: To compare the root mean square (RMS) of anterior corneal higher-order aberrations (HOAs) in ametropic and emmetropic eyes.

Methods: This retrospective observational study was conducted at the Department of Ophthalmology, Tishreen University Hospital, Latakia, Syria. Study eyes were divided into four groups based on refractive error: mild-to-moderate myopia, hypermetropia, myopic astigmatism, and emmetropic eyes as controls.

Clinical Outcomes of Accelerated Corneal Cross-Linking for Pediatric Keratoconus.

Aim: To assess the efficacy and safety of accelerated corneal cross-linking in the treatment of pediatric keratoconus.

Method: In this retrospective case series, 29 eyes of 20 pediatric patients with keratoconus underwent accelerated corneal cross-linking. Treatment was delivered at 10 mW/cm for 9 minutes with a total dose of 5.
