To compare the outcomes of a toric phakic intraocular lens (PIOL) and a spherical PIOL combined with astigmatic keratotomy (AK) for the correction of high myopic astigmatism. This study enrolled patients with high myopic astigmatism, including 30 eyes (2
(0.317 ± 0.215 vs 0.338 ± 0.148 μm,P = 0.043; and 0.281 ± 0.207 vs 0.314 ± 0.153 μm,P < 0.001). The incidence of eyes with negative total corneal primary spherical aberration increased as axial length increased in the high myopia group, and the...
The lens system provided a 1:1 magnification, producing a 8 × 12 mm field of view. For the single stage experiments, one HPVX-2 camera was used to record every third X-ray bunch, giving an inter-frame time of 0.528 μs and frame-rate of 1.89 Mfps. This three-bunch minimum ...
Correction of Astigmatism requires the addition of some kind of cylindrical power to a standard correction. The added cylinder will have both a magnitude and an axis. This alone greatly multiplies the number of correction prescriptions offered. Spectacle lens correction has been most successful at ...
