Comparative study of 3 intracorneal implant types to manage central keratoconus

摘要

Purpose: To compare the visual acuity, refraction, corneal topography, and corneal asphericity of intrastromal corneal implantation of Keratacx 160-degree 2 symmetrical ring segment, the Keratacx 320-degree near-total ring, and the Myoring continuous intracorneal ring (ICR) in central keratoconus.
