Both cis and trans isomers of FCSF were generated by irradiation of Ar matrix isolated F(2)CS at 16 K with an ArF excimer laser (lambda = 193 nm).

PURPOSE To evaluate long-term follow-up results of excimer laser phototherapeutic keratectomy (PTK) in a Japanese population. METHODS Twenty-six patients (31 eyes) with corneal opacity were treated with excimer laser PTK. Preoperative diagnoses included 16 eyes with band keratopathy, 10 with granular dystrophy, and 5 with corneal scar. Mean postoperative follow-up was 27 months. RESULTS Cor...

BACKGROUND The purpose of this paper is to report the results of using combined treatment of customized excimer laser-assisted photorefractive keratectomy (PRK) and prophylactic corneal collagen crosslinking (CXL) for residual refractive error in a group of patients who had previously undergone lamellar keratoplasty for keratoconus. METHODS The study included 14 eyes from 14 patients who had ...
