Objective
To determine the outcome of excimer laser phototherapeutic keratectomy (PTK) for Haab-Dimmer corneal dystrophy.
Methods
Four eyes of two patients who underwent excimer PTK for recurrent erosions and reduced vision due to Haab-Dimmer dystrophy, between October 1998 and May 2001, were reviewed. Data regarding the preoperative and postoperative best-corrected visual acuity , change in spherical equivalent, refraction, symptomatic relief, and incidence of recurrence were analysed by a retrospective chart review.
Results
During the 20-63 month long follow-up period, all eyes improved BCVA, a slight hyperopic shift was found in two cases. All patients were free of symptoms of recurrent erosions and there were no major complications.
Conclusions
Excimer PTK is a safe and effective procedure for relieving symptoms of recurrent erosions and improving visual acuity in patients with Haab-Dimmer dystrophy.
