Annular keratotomy for the treatment of painful bullous keratopathy
1Cornea Service, Eye Institute, Medical College of Wisconsin, USA.
Purpose:
To determine whether annular keratotomy can relieve pain associated with bullous keratopathy.
Methods:
Three patients with painful bullous keratopathy and poor visual potential underwent partial-thickness (0.30 to 0.42 mm) trephination of the cornea under local anesthesia.
Results:
All patients reported an absence of pain and foreign body sensation during an average follow-up interval of six months. The surgical procedure was uncomplicated; however, two eyes developed increased central corneal stromal edema.
Conclusions:
Annular keratotomy appears to be a relatively safe and simple surgical procedure that may be useful in managing pain in eyes with painful cornea edema and poor visual potential.
