PURPOSE: To report the long-term outcomes after phototherapeutic keratectomy (PTK) for the treatment of bullous keratopathy.
METHODS: This is a retrospective medical record review of all patients with symptomatic bullous keratopathy who underwent PTK between June 2005 and March 2019 at the Royal Victorian Eye and Ear Hospital who were followed up for at least 12 months after the procedure. Medical records were used to extract demographic data, etiology of bullous keratopathy, complication rates, and subsequent procedures after PTK. The main outcomes recorded were pain and recurrence of bullae, which were assessed according to three time periods: 0 to 3 months, 4 to 12 months, and greater than 12 months after PTK.
RESULTS: During the study period, 64 eyes of 64 patients underwent PTK for bullous keratopathy. The mean follow-up duration was 51 months (range 12-140). The most common indication was pseudophakic bullous keratopathy (44% of cases). Pain had resolved in 88% of eyes within 0 to 3 months, 77% of eyes between 3 and 12 months (P = 0.031, compared with 0-3 months), and 70% of eyes with greater than 12-month follow-up (P = 0.131, compared with 3-12 months). Bullae recurred in 17% of eyes within 0 to 3 months, 22% of eyes between 3 and 12 months (P < 0.001 compared with 0-3 months), and 33% of eyes after the 12-month follow-up (P < 0.001 compared with 3-12 months). Eighty-six percent of patients undergoing PTK had no postoperative complications, and 73% of cases did not require subsequent procedures.
CONCLUSIONS: PTK is effective in providing long-term symptom relief from bullous keratopathy in most of the treated patients.
