Higher order aberrations in normal, dilated, intraocular lens, and laser in situ keratomileusis corneas.

摘要: PURPOSE: To compare repeated measures of Zernike polynomial higher-order aberrations in 29 normal, 13 dilated 11 intraocular lens (IOL), laser situ keratomileusis (LASIK), and one refractive keratectomy (RK)/IOL subject. METHODS: At least three Shack-Hartmann images were obtained from each subject, higher order (uncorrectable by spectacles) representation was determined. For confidence intervals for coefficient determined as a function pupil size. Significant (P<.05) coefficients averaged within groups, group means compared to normal subjects. RESULTS: No differences seen between the groups at P=.05. The patients with prior LASIK IOL surgery showed statistically significant elevation 4th spherical aberration total wavefront variance sizes greater than 5 mm, normals. CONCLUSION: Both elevate variance, increasing magnitude effect size, although pupillary dilation alone did not produce different changes, These findings demonstrate that implantation can more net LASIK, new opportunity optimize surgical results.
