Interface fluid syndrome in routine cataract surgery 10 years after laser in situ keratomileusis.

Purpose: Interface fluid syndrome is an unusual complication after laser in situ keratomileusis (LASIK). We present a case of interface fluid syndrome after cataract surgery in a patient who had previous LASIK surgery.

Methods: A 62-year-old man underwent routine cataract surgery on the left eye 10 years after LASIK on both eyes. The day after surgery, the intraocular pressure (IOP) was 21 mm Hg and a pocket of fluid was present in the interface LASIK wound. The patient was treated with 0.50% timolol eye drops twice daily.

Results: The problem resolved within 1.5 months. Two months later, the patient underwent routine cataract surgery of the right eye. The next day, the IOP was 11 mm Hg and LASIK interface fluid was present. The patient was treated with 0.5% timolol eye drops twice daily. Two months after the surgery, the problem had completely resolved.

Conclusions: Ocular hypertension and traumatic endothelial cell damage could have been the causes of the syndrome. Although the IOP was not very high, previous LASIK could have led us to underestimate the IOP.
