Summary
A small Nd:YAG capsulotomy can cause monocular diplopia. Larger capsulotomy size may prevent visual disturbances after posterior capsulotomy for posterior capsular opacification.
Area of Science:
- Ophthalmology
- Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser procedures
Background:
- Posterior capsular opacification (PCO) is a common complication after cataract surgery.
- Nd:YAG laser capsulotomy is a standard procedure to treat PCO.
Observation:
- A 57-year-old male presented with horizontal monocular diplopia in his right eye.
- The patient had undergone a Nd:YAG capsulotomy three weeks prior.
- Slit-lamp examination revealed a small capsulotomy and Elschnig pearls, identified as the cause of diplopia.
Findings:
- Repeat Nd:YAG laser capsulotomy successfully resolved the monocular diplopia.
- This case highlights monocular diplopia as an unusual complication of Nd:YAG laser capsulotomy.
Implications:
- Capsulotomy size is a critical factor in preventing visual disturbances.
- Ensuring capsulotomy is larger than the scotopic pupil diameter may avoid complications like monocular diplopia.
- This emphasizes the importance of precise laser parameters in ophthalmic procedures.
