Abstract
-
The clinical evaluation of the "O3/O4" series of Bausch and Lomb company for extended wear were performed in 138 eyes of 69 patients. In 128 eyes(92.1%) of them the corrected visual acuity over 0.8 was obtained and wearing periods of contact lenses were ranged from 1 day to 3 weeks (mean: 9.2 days). 117 eyes were satified with the contact lenses having no remarkable complications. There were no significant changes in corneal curvature between the examinations before and after contact lens wearing. From the above results, it can be suggested that the O3/O4 extended wear soft contact lenses are clinically available with excellent improvement of visual acuity.
