Phototherapeutic keratectomy for bullous keratopathy.
AIMS This study was designed to investigate the therapeutic potential of excimer laser for recurrent painful erosions in patients not suited to treatment with penetrating keratoplasty. METHODS Phototherapeutic keratectomy (PTK) with the excimer laser was performed prospectively on a series of 13 eyes of 12 patients with recurrent corneal erosions in connection with bullous keratopathy of vari...
متن کاملInfluence of ablation parameters on refractive changes after phototherapeutic keratectomy.
PURPOSE The aim of the current study was to control the hypothetical effects of decreased laser energy delivered to the peripheral cornea during phototherapeutic keratectomy (PTK) and provide quantitative calculation of induced low and high order aberrations. METHODS We employed a model eye to simulate the refractive effect of homogeneous laser corneal irradiation, as in PTK, for different la...
متن کاملImmunohistochemical study of subepithelial haze after phototherapeutic keratectomy.
PURPOSE Subepithelial haze is a frequent complication and is often the cause of regression after photorefractive keratectomy (PRK). The lack of understanding of this undesirable complication following PRK is in part due to the limited availability of suitable tissues for pathological studies. METHODS We examined the expression of various extracellular components in the cornea of a 46-year-old...
متن کاملPhototherapeutic keratectomy for epithelial basement membrane dystrophy
PURPOSE The purpose of this study was to evaluate the long-term efficacy of phototherapeutic keratectomy (PTK) in treating epithelial basement membrane dystrophy (EBMD). METHODS Preoperative and postoperative records were reviewed for 58 eyes of 51 patients with >3 months follow-up (range 3-170 months) treated for EBMD with PTK after failure of conservative medical treatment at Byers Eye Inst...
