Abstract
Purpose
This study evaluated the safety and efficacy of Bowman’s membrane electrocautery in blind painful eyes with bullous keratopathy not amenable to corneal transplantation.
Methods
Eleven eyes of 11 subjects with painful bullous keratopathy and poor visual potential who underwent electrocautery of Bowman’s membrane at a tertiary referral ophthalmology clinic were reviewed retrospectively. Subject demographics and preoperative and postoperative data were collected, including description of pain, slit lamp biomicroscopy, best corrected visual acuity, topical medication use, and complications. Efficacy of the procedure on pain reduction, bullae resolution, and topical medication use were assessed at post-operative visits. Safety was also evaluated based on any complications.
Results
Bowman’s membrane electrocautery effectively resolved bullae in all eyes examined up to 6 months postoperatively; however, 2 eyes had recurrence by 1 year. Mean age at the time of surgery was 69.8 years and mean duration of follow-up was 15.4 months. Pain reduction was achieved in all eyes at 1 month, but 1 subject had pain recurrence by 6 months and another by 1 year. The median number of drops per day decreased from 6 preoperatively to 1.7 at 6 months. Two subjects who had underlying advanced ophthalmic disease had a mild reduction in vision.
Conclusion
Bowman’s membrane electrocautery is a safe and minimally invasive procedure for the management of painful bullous keratopathy in eyes with low vision potential and not amenable to corneal transplantation. Duration of effect appears to last at least 6 months and up to 3 years post-procedure.
