Summary
A new complication of laser in situ keratomileusis (LASIK) involves interface fluid accumulation and corneal edema, causing decreased visual acuity. Discontinuing corticosteroids and using glaucoma medication resolved the issue, highlighting the need for early recognition.
Area of Science:
- Ophthalmology
- Refractive Surgery
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery procedure.
- Complications, though rare, can occur and impact visual outcomes.
Observation:
- A patient developed decreased visual acuity and corneal edema post-LASIK.
- Slit-lamp examination revealed significant fluid accumulation in the corneal interface.
- Initial intraocular pressure readings were deceptively low due to fluid compressibility.
Findings:
- Interface fluid accumulation and corneal edema represent a novel complication of LASIK.
- Discontinuation of topical corticosteroids and initiation of antiglaucoma medication led to resolution.
- Corneal clearing and improved visual acuity were observed after treatment.
Implications:
- Early identification of interface fluid is crucial for managing this LASIK complication.
- Falsely low intraocular pressure readings can be an indicator of interface fluid.
- A revised management strategy involving corticosteroid cessation and glaucoma medication is effective.
