Keratoconus is the most common corneal ectatic disorder. It is characterized by progressive
corneal thinning with resultant irregular astigmatism and myopia. Its prevalence has been …

Background Keratoconus is an ectatic, progressive corneal disorder characterized by
alterations in the morphology of the corneal tissue that leads to limitation of visual function of …

Corneal allogenic intrastromal ring segments (CAIRS) refer to the intracorneal placement of
fresh, unprocessed, processed, preserved, or packaged allogenic rings/segments of any …

PURPOSE: To analyze the clinical outcomes obtained with asymmetric intracorneal corneal
ring segments (ICRS) of variable thickness and width in patients with keratoconus …

Purpose To evaluate the local geometric effects of a unilateral intrastromal ring segment with
a combined variation of ring thickness and base width in a finite element simulation, and to …

Purpose To describe the anatomical and functional results of the implantation of asymmetric
thickness intracorneal ring segments (AS-ICRS) in eyes with keratoconus and …

Purpose: To evaluate clinical outcomes in patients with asymmetric duck phenotype
keratoconus implanted with asymmetric progressive thickness intrastromal corneal ring …

Purpose: The aim of this study is to describe visual outcomes and epithelial remodeling
following the implantation of asymmetric intracorneal ring segments (ICRSs) of variable …

PURPOSE: To assess the outcomes of implanting a new 300° arc-length intrastromal
corneal ring segment (ICRS) in moderate to advanced central hyperprolate keratoconus …

Purpose: To evaluate and compare visual and refractive outcomes after implantation of the
intracorneal continuous ring 360° arc (ICCR) versus the intracorneal ring segment 340° arc …
