ABSTRACT
Purpose
Presenting the course of visually disabling corneal infiltration post uneventful collagen cross-linking (CXL) in a 23 years old male with bilateral keratoconus.
Methods
A 23 years old male with bilateral keratoconus underwent cross-linking of left eye with indigenous 0.1% riboflavin dye and 370 nm ultraviolet A irradiation. This patient had an uneventful successful cross-linking performed in right eye 6 months prior with good recovery of vision to LogMAR (6/9 Snellen).
Results
Patient developed diminution of vision, along with redness of eye, photophobia and watering on 3rd day after uneventful cross-linkage. Examination revealed very poor vision; diffuse corneal clouding with multiple superficial stromal infiltrates and incomplete corneal epithelization. A provisional diagnosis of infective keratitis was made, in situ bandage contact lens (BCL) removed and subjected to culture. Intensive fortified topical antibiotics were initiated and steroids withheld. After complete corneal re-epithelization on 6th day, the infiltrations did not decrease in either intensity or number. Response to antibiotics being inadequate, an immune etiology was suspected and full strength topical steroids reinstituted which resulted in slow resolution of infiltration over a 10 weeks period. Last follow-up at 9 months post-CXL, revealed a diffuse stromal haze with unaided visual acuity of LogMAR 0.8 6/36 and best-corrected visual acuity (BCVA) of 0.3 (6/12) with use of a rigid gas permeable lens.
Conclusion
Sterile infiltration post-CXL requiring intense topical steroids is a rare complication of CXL and needs to be differentiated from infective keratitis.
