Intrastromal corneal ring segment implantation for ectasia after refractive surgery.
PURPOSE To evaluate the clinical outcomes of intrastromal corneal ring segment (ICRS) implantation to correct ectasia in eyes with prior refractive surgery. METHODS Forty-one eyes of 25 patients (13 men, 12 women; mean age, 28.66 years) with ectasia after refractive surgery [photorefractive keratectomy (PRK) or laser in situ keratomileusis (LASIK)] were included in a nonrandomized, retrospect...

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...

PURPOSE To assess the outcomes of intrastromal corneal ring (ISCR) implantation for the treatment of corneal ectasia. METHODS Thirty-five consecutive patients with secondary corneal ectasia treated with keraring intrastromal corneal ring segment implantation aided by intralaser femtosecond technique (K-ICRS-FS) were evaluated. Visual acuity (logMAR), refraction and astigmatism vector analysis...
متن کاملReasons for intrastromal corneal ring segment explantation.
Reasons for intrastromal corneal ring segment explantation In their recent article, Ferrer et al. report that 57 of 250 implanted intrastromal corneal ring segments (ICRS) had to be explantedda rate of 22.8%. The main cause of this very high explantation rate was extrusion (48.3%). There are 2 major causes of ICRS extrusion: (1) superficial implantation of a segment and (2) a segment that is pl...
متن کاملSimultaneous intratunnel cross-linking with intrastromal corneal ring segment implantation versus simultaneous epithelium-off cross-linking with intrastromal corneal ring segment implantation for keratoconus management
Purpose The purpose of this study is to compare the efficacy of intratunnel cross-linking combined with intrastromal corneal ring segment (ICRS) implantation versus combined epithelium-off (epi-off) cross-linking and ICRS implantation for the management of keratoconus. Methods Our study included 20 eyes of 12 patients with moderate-to-severe keratoconus. Group A included 10 eyes that underwen...
