Treatment of traumatic corneal flap fold after LASIK

Abstract

Objective To investigate the treatment of traumatic corneal flap fold after laser in situ keratomileusis(LASIK). Methods We opened the corneal flap which had folds by topical anesthesia. Corneal bed and corneal flap bed were rinsed and proliferative epithelial tissue was remored. We expanded and paved the corneal flap folds to make it stick to the corneal bed with dear margins. Ten patients (10 eyes)with traumatic corneal flap fold were analyzed with following-up for 6 months after surgery. Results 1. UNVA In the second day after surgery ,9 patients' uncorrected visual acuites(UNVA) were not less than 0. 6 ;In the 6 months after surgery, 9 patients' UNVA were 0. 6 ～ 1.2(0. 8 ±0. 16) ,1 patient' uncorrected visual acuity was 0. 2 with macular hemorrhage. 2. Slit lamp biomicroscopic examination. There was stromal edema around the corneal flap contusion with good contraposition in 2 cases at 1 day postoperatively. 3 cases had epithelial ingrowth around the margin with slightly swollen epithelia. The corneal flaps could restore right position after the surgical treatment for epithelial ingrowth. The corneal flap folds in all cases become flattened at 6 months postoperatively. Conclusion Traumatic corneal flap fold after LASIK can be eliminated by the timely and proper treatment. There is no serious impact on vision.
