Abstract
AIM: To observe the curative effect of bandage contact lens in neurogenic keratitis. METHODS:Twenty cases of neurogenic keratitis were studied at the Department of Ophthalmology, the first Affiliated Hospital of China Medical University, between October 2012 and June 2013. These included 13 males and 7 females, aged from 35 to 88y. Patients were voluntarily divided into an experimental group (lens wearing group, n=10) and control group (drug therapy, n=10). In experimental group patients wore silicone hydrogel bandage soft contact lens. Both groups used the following eyedrops: 0.5% levofloxacin TID; 0.5% Sodium carboxymethyl cellulose QID; fibroblast growth factor BID; ganciclovir BID [cases complicated with herpes simplex virus (HSV)]; compound tropicamide BID (cases concurrent hypopyon). The healing time of corneal ulcer and complication rates were observed in the two groups. RESULTS: The healing time of corneal ulcer in the experimental group was 10.80±4.44d versus 46.70±13.88d in the control group (P<0.05). No complications occurred in the experimental group, except for the lens falling off twice in one case, the patient recovered eight days after rewearing the lens. While in the control group, all cases vascularized, 2 cases were complicated with descemetocele that recovered with amniotic membrane transplantation and 1 case was complicated with corneal perforation that recovered by autologous conjunctival flap covering. CONCLUSION:Bandage contact lens is a safe and effective method of treating neurogenic keratitis and significantly shortened the healing time of corneal ulcer.
