ferrara intrastromal corneal ring segments in keratoconus
purpose: to evaluate the efficacy and safety of ferrara intra-stromal corneal ring (fiscr) segments for keratoconus. methods: the study was performed on 57 eyes of 44 patients with keratoconus and clear cornea who were contact lens intolerant. subjects underwent complete ophthalmic examination before surgery. objective and subjective refraction achieving the best visual acuity was used to deter...
متن کاملKeraRing intrastromal corneal ring segments for correction of keratoconus.
PURPOSE Intrastromal corneal ring segments (ICRSs) are small arc-like implants that are being used increasingly as a minimally invasive treatment for patients with keratoconus. This study assessed the effectiveness of KeraRing implants, a type of ICRS, to treat keratoconus. METHODS Retrospective case series descriptive study of 43 patients (55 eyes) with keratoconus who underwent KeraRing imp...
متن کامل[Asymmetric intrastromal corneal ring for the treatment of keratoconus].
PURPOSE To analyze corneal curvature and visual acuity after asymmetric intrastromal corneal rings implantation, not following the nomogram proposed by the manufacturer. METHODS Seven eyes of seven keratoconus patients which had asymmetric corneal rings implanted in their corneal stroma were studied. RESULTS A flattening of the average corneal keratometry was noted in all patients, as well ...
متن کاملIntrastromal corneal ring segment implantation for the treatment of keratoconus.
PURPOSE To evaluate the safety and efficacy of intrastromal corneal ring segment implantation using both mechanical and femtosecond-assisted tunnel creation for the treatment of patients with keratoconus. METHODS A retrospective noncomparative interventional study including 96 eyes of 75 patients with keratoconus. All patients had contact lens intolerance and clear central corneas. Corneal tu...
متن کاملCorneal Asphericity Changes after Implantation of Intrastromal Corneal Ring Segments in Keratoconus
Keratoconus is a progressive corneal thinning of unknown cause in which the cornea assumes a conical shape, with progressive irregular astigmatism and deterioration of visual acuity. The normal anterior corneal surface is prolate, and it could be described as conic (flattening of the radius of curvature from the apex toward the periphery)1. In keratoconus corneas, the steepening of the central ...
