ABSTRACT
This project was aimed to develop a simple, convenient and reliable computer image processing software for the measurement of lens dimensions, including the radius of curvature of anterior lens surface (RCALS), the radius of curvature of posterior lens surface (RCPLS) and the lens volume (LV). On the basis of lens images captured by B ultrasound, our computer software was designed to calculate the three parameters of lens in accordance to geometry principle. This software comprises Program I and Program II, and they both possess different calculation methods. Then they were used in a group of normal volunteers who were recruited via randomization and the outcomes were compared. The results showed that the two programs were developed successfully, and the outcomes of RCALS, RCPLS and LV calculated by the two programs were similar. The standard deviation of Program II is smaller than that of Program I. The computer software for calculating RCALS, RCPLS and LV was characterized by scientific design and easy-to-use. In respect of calculating repetition, Program II was better than Program I, and it possesses prosperous prospect in terms of clinical research and application.
