Phototherapeutic Keratectomy Outcomes in Superficial Corneal Opacities
PURPOSE COMPARE THE EFFECTIVENESS OF PHOTOTHERAPEUTIC KERATECTOMY (PTK) IN TREATMENT CORNEAL DYSTROPHIES VERSUS SUPERFICIAL CORNEAL SCARS: visual outcomes, recurrence rate and safety profile. METHODS PTK was performed in 51 eyes of 51 patients. Data regarding the indications for PTK, ablation depth, symptomatic relief, pre-and postoperative best spectacle-corrected visual acuity (BSCVA), sphe...
متن کاملPentacam-based phototherapeutic keratectomy outcome in superficial corneal opacities
PURPOSE This study aimed to evaluate the effectiveness of phototherapeutic keratectomy (PTK) as an alternative treatment to keratoplasty using the Pentacam to assess depth of dense opacities. METHODOLOGY PTK was performed in eleven eyes of ten patients with superficial corneal opacities after assessment by Scheimpflug images of the Pentacam for central corneal thickness (CCT) and opacity leve...
متن کاملTen-year results of phototherapeutic keratectomy on recurrent corneal erosions.
PURPOSE To determine the ten-year visual results and outcomes of excimer laser phototherapeutic keratectomy (PTK) for recurrent corneal erosions. METHODS Twenty-six eyes of 23 patients with recurrent corneal erosions were treated by PTK from 1996 to 2000 at the Goiania Eye Institute, Brazil. All eyes had failed to respond to conventional therapy. Data regarding preoperative and postoperative ...
متن کاملPhototherapeutic keratectomy re-treatment for recurrent corneal erosion syndrome.
AIMS Phototherapeutic keratectomy with an excimer laser is commonly used to treat recurrent corneal erosion syndrome. The aim of this study was to determine the success of a repeat phototherapeutic keratectomy for patients with persistent macroerosions following initial treatment with phototherapeutic keratectomy. METHODS Eight patients who failed primary phototherapeutic keratectomy for recu...
متن کاملCorneal hysteresis changes in diabetic eyes.
In their recent article, Goldich et al. found that corneal hysteresis (CH), corneal resistance factor (CRF), and central corneal thickness were significantly higher in diabetic eyes than in healthy eyes and CH was claimed to be related to the corneal stiffness. However, we found significantly lower CH values in diabetic eyes than in eyes of healthy subjects. We believe that the statements that ...
