Abstract

Purpose To compare amniotic membrane transplantation (AMT) and anterior stromal puncture (ASP) in the management of pain in patients with symptomatic bullous keratopathy (BK).

Methods In this prospective comparative study, 40 eyes of 40 patients with symptomatic BK (chronic intermittent pain) were randomised and divided into two groups (AMT and ASP) according to the technique used to treat symptomatic BK. The patients were examined on days 1, 14, 30, 90 and 180 postoperatively. Patients with BK under the age of 18 with raised eye pressure, concurrent ocular surface infection and those without any pain were excluded.

Results At follow-up at 90 and 180 days the presence of a regular epithelial surface was higher in the AMT group (60% and 50%, respectively) than in the ASP group (16.7% and 6. 3%, p=0.006 and p=0.008, respectively). At 180 days follow-up there was no statistical difference between the two groups in the severity (p=0.391) or duration (p=0.715) of pain.

Conclusions AMT is similar to ASP in the relief of pain in symptomatic BK. However, ASP is a simple outpatient procedure and should cost less than AMT.
