Abstract:
To determine the effects of contact lens-solution(Uni-cleaner, Uni-soak, Uni-rince on the ocular tissue following instillation for 21 consecutive days, the experimental irritation study was conducted on the rabbit eyes. Nine rabbits(18 eyes) were divided into three groups and each solution was instilled into the eyes four tims a day for 21 consecutive days. Ocular reactions including conjunctival injection, chemosis, sodium fluorescein stain, and erosion were observed and recorded. The reactions were noted using as a guide the scales for scoring from grade I to grade IV according to the severity through the slit lamp examination, and also measured was the corneal thickness change using the ultrasonic pachometer. The results were as follows; 1. No ocular abnormalitis were observed during the slit lamp examination through the test period except one minute after instillation of the solution. 2. The changes of the corneal thickness were not significant statistically(p>0.1). 3. Scanning electronic microscopy showed that epithelial cells formed a polygonal mosaic on surface of the cornea and microvilli and microplicae were present in adjacent cells.
