Full-Ring Intracorneal Implantation in Corneas With Pellucid Marginal Degeneration
BACKGROUND Keratoconus (KCN) is a progressive, non-inflammatory ectacic disorder characterized by bilateral and asymmetrical conical protrusion of the cornea. MyoRing implantation and Collagen Crosslink (CXL) are two separate effective treatments for all stages of keratoconous. This study wants to show the effect of these treatments combination in patients with moderate and severe keratoconus. ...

PURPOSE To evaluate refractive, visual, and aberrometric changes in corneas with pellucid marginal degeneration (PMD) implanted with intracorneal ring segments (ICRS) during a 6-month follow-up. DESIGN Retrospective, consecutive case series. PARTICIPANTS We included 21 consecutive eyes of 15 patients ranging in age from 21 to 73 years old and with a diagnosis of PMD. This diagnosis was made...

متن کاملPredictability of Tunnel Depth for Intrastromal Corneal Ring Segments Implantation Between Manual and Femtosecond Laser Techniques.
PURPOSE To compare the predictability of intrastromal tunnel depth creation for intrastromal corneal ring segments (ICRS) implantation between manual dissection and femtosecond laser using a high-resolution anterior segment optical coherence tomography (AS-OCT). METHODS This multicenter study included patients with keratoconus who had Ferrara-type ICRS implantation at Hospital de Braga using ...
