Laser synechialysis to prevent membrane recurrence on silicone intraocular lenses
1Section of Ophthalmology, Dartmouth-Hitchcock Medical Center, Lebanon, NH 03756-0001, USA.
Purpose:
To determine whether laser posterior synechialysis will prevent recurrence of pigmented membranes that can form on the anterior surface of silicone intraocular lenses.
Methods:
Three patients (four eyes) had posterior synechiae and silicone intraocular lens surface membranes that required long-term corticosteroid treatment. Posterior synechiae were lysed by an Nd:YAG laser (1 to 2 mJ per burst; 148 to 485 applications; total energy, 296 to 896 mJ).
Results:
All four eyes remained free of recurrence from 12 to 14 months.
Conclusions:
Silicone intraocular lens surface membranes emanated from posterior synechiae. The Nd:YAG laser synechialysis prevented recurrence and allowed discontinuation of corticosteroids.
