Recurrent rates and risk factors associated with recurrent painful bullous keratopathy after primary phototherapeutic keratectomy.

Objective: To assess the recurrent rate, mean survival time, and risk factors associated with recurrent painful bullous keratopathy (BK) after primary treatment with phototherapeutic keratectomy.

Methods: Medical records from 72 patients (72 eyes) who had phototherapeutic keratectomy for painful BK were evaluated. Data for sex, age, duration of BK, associated ocular and systemic diseases (hypertension, diabetes mellitus, ischemic heart disease, asthma, dyslipidemia, and rheumatoid arthritis), frequency and degree of pain (grade 1-3), visual acuity, corneal thickness, intraocular pressure, and laser setting were extracted and analyzed.
