Abstract
-
The clinical life-time and the causes for the change of soft contact lens(SCL) were analyzed according to the sex, age and kinds of SCL. The clinical life-time(time interval of changing of the SCL) was 6.9 months on the average. In the clinical life-time and the causes for the change of SCL, there were no sexual difference and also no difference between plus and minus lenses(p>0.05). However, there were significant differences in them according to the age and kinds of SCL(p<0.05).In groups below 10 years old and over 60 years old, and in the extended SCL, loss rates were relatively high. This was thought to be related to shortening theclinical life-time of SCL.
