Abstract
Nt change. Mean spherical equivalent refraction before laser treatment, estimated from the prescription of spectacles, was 0.30 diopters (D). Mean subjective refraction after laser treatment was 0.24 D. The difference was not significant. Mean capsulotomy opening diameter increased from 3.44 mm ± 0.61 mm (±SD) immediately after the laser treatment to 3.67 mm ± 0.61 mm one month later. The increase was statistically significant. Intraocular lens position and spherical equivalent refraction did not change after the YAG laser capsulotomy, despite a significant increase in area of the capsulotomy opening. cReprint requests to Peter Thornval, M.D., Department of Ophthalmology, Aalborg Sygehus Syd, 9000 Aalborg, Denmark.
