Summary
A rare case of bilateral disciform keratopathy occurred after laser in situ keratomileusis (LASIK). This complication, potentially caused by microkeratome blade reuse, highlights the importance of using new blades for LASIK surgery.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery procedure.
- Complications, though rare, can occur following LASIK.
Observation:
- A 28-year-old male presented with bilateral, painless vision loss five days post-LASIK for hyperopia.
- Examination revealed bilateral disc-shaped corneal lesions.
- The patient underwent simultaneous bilateral LASIK using a Chiron Technolas 217 excimer laser with a Hansatome microkeratome, which had previously used blades installed.
Findings:
- The corneal lesions were diagnosed as disciform keratopathy.
- Intense topical steroid therapy led to the resolution of the lesions within three weeks.
Implications:
- The reuse of microkeratome blades is a potential cause of post-LASIK disciform keratopathy.
- Using a new microkeratome blade for each eye and meticulous cleaning are crucial preventive measures.
- This case underscores the importance of surgical technique and instrument sterilization in preventing LASIK complications.
