| Abstract;Purpose: To evaluate the chromatic aberration of the eyes with a poly(methylmethacrylate)(PM-MA) intraocular lens or a soft acrylic intraocular lens(AcrySof), by comparing them with normal eyes. Subjects and methods: The longitudinal chromatic aberration(LCA) of the eye was measured by a modified chromoretinoscopy of Bobier & Sivak, for 48 eyes with a PMMA intraocular lens, 49 eyes with an AcrySof, and 27 eyes with a normal lens. In addition, these LCAs were calculated theoretically by the paraxial ray-tracing technique with a personal computer. Results: The average values of the LCA between the wavelengths of 500nm and 640nm were 0.75.+-.0.18D(mean.+-.standard deviation) in PMMA eyes, 1.20.+-.0.22D in AcrySof eyes, and 0.82.+-.0.16D in normal eyes. The calculated LCA was 0.64D in the PMMA eye, 0.98D in the AcrySof eye, and 0.74D in the normal eye(Gullstrand's thematic eye). Conclusion: The PMMA eyes had chromatic aberrations almost equal to those of the normal eyes, whereas the AcrySof eyes have significantly larger aberrations. Therefore, we conclude that quality of the retinal image is reduced in eyes with an AcrySof lens. (author abst.) |
