March 30, 2023 updated by: Prof. Mohammed Iqbal, Sohag University

Analysis of the Outcomes of Three Different Cross-linking Protocols for Treatment of Pediatric Keratoconus

comparison between standard cross-linking protocol and accelerated and transepithelial cross-linking

Study Overview

Detailed Description

comparison between standard cross-linking protocol and accelerated and transepithelial cross-linking for treatment of documented pediatric keratoconus progression. The study patients are divided into 3 groups. Group A patient treated with standard cross-linking. Group B patients treated with accelerated cross-linking. Group C patients treated with transepithelial cross-linking.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: Standard CXL
Patients treated according to Dresden Protocol with epithelium-off CXL.
Epithelium-off CXL performed by removal of corneal epithelium, instillation of riboflavin onto the cornea followed by UVA corneal irradiation for 30 minutes.
Experimental: Accelerated CXL
Patients treated according to accelerated Protocol with epithelium-off CXL.
Epithelium-off CXL performed by removal of corneal epithelium, instillation of riboflavin onto the cornea followed by UVA corneal irradiation for 5 minutes.
Experimental: Transepithelial CXL
Patients treated according to transepithelial Protocol with epithelium-on CXL.
Epithelium-on CXL performed by instillation of riboflavin onto the cornea followed by UVA corneal irradiation for 5 minutes.
