Summary
LASIK flap amputation can improve corrected vision for flap complications like opacities or astigmatism when other treatments fail. However, uncorrected vision and astigmatism may worsen, requiring careful patient discussion.
Area of Science:
- Ophthalmology
- Refractive Surgery
- Corneal Surgery
Background:
- Atypical LASIK flap complications can be challenging to manage.
- Conservative treatments are often ineffective for persistent flap issues.
Observation:
- A case series reviewed seven eyes of six patients undergoing LASIK flap amputation.
- Indications included flap/interface opacity, irregular astigmatism, and chronic pain.
- All patients had previously failed conservative management.
Findings:
- LASIK flap amputation led to symptomatic improvement and better corrected visual acuity in all patients.
- However, uncorrected distance visual acuity worsened in two patients.
- Manifest refraction and irregular astigmatism also worsened in some patients post-procedure.
Implications:
- Flap amputation is a viable option for specific refractory LASIK flap complications.
- Informed consent must address potential worsening of uncorrected acuity and irregular astigmatism.
- This procedure offers a therapeutic alternative when other measures are exhausted.
