Abstract
Radial keratotomy utilizing the American technique was performed on ten rabbit eyes. After 3 months, operated eyes were fitted with extended wear soft contact lenses for 2 weeks and as control group, the normal ten rabbit eyes were also fitted with the same contact lenses. Corneal thickness using ultrasonic pachymeter was measured and corneal neovascularization along the incision lines was observed and the numbers of involved incision lines was recorded. The results were as follows; 1) The mean central corneal thickness of normal rabbits before and after 2 weeks of soft contact lenses wear was 0.377mm, 0.391mm respectively. 2) The mean central corneal thickness of preoperative, postop. 3 months and 2 weeks after contact lens wear was 0.380mm, 0.382mm, 0.397mm respectively. 3) The thickness of control group and experimental group showed no statistically significant difference. 4) In control group there was no corneal neovascularization after contact lens wear. While in experimental group six eyes(60%) developed the corneal neovascularization and the average length of corneal neovascularization was 2.32mm(maximum 4.7mm) (Table 3, Fig. 1,2,3).
