UNASSIGNED: Case Series.
UNASSIGNED: Twenty-three patients who had undergone secondary IOL placement using flanged intrascleral fixation technique.
UNASSIGNED: Retrospective chart review.
UNASSIGNED: Corrected distance visual acuity (CDVA) and postoperative spherical equivalent based on manifest refraction.
UNASSIGNED: Visual acuity improved from 20/577 to 20/58. Overall, the actual refraction was 0.06 D more myopic than predicted. Holladay 2, Sanders Retzlaff Kraff/Theoretical (SRK/T) and Barrett Universal II resulted in mild myopic surprise (-0.55, -0.18 and -0.20 D). Haigis and Hill-RBF (Radial Basis Function) resulted in mild hyperopic surprise (+0.28 and +0.28 D). Hoffer Q and Holladay 1 were the most accurate (-0.02D and -0.08 D).
UNASSIGNED: Flanged intrascleral IOL fixation improved vision even in patients with other posterior segment pathologies. The effective lens positioning is likely similar to in-the-bag positioning. Hoffer Q and Holladay 1 formulas with in-the-bag calculations were the most accurate.
■案例系列。
■23例患者使用法兰巩膜内固定技术进行了二次IOL置入。
■回顾性图表回顾。
■根据明显的屈光校正了远距视敏度(CDVA)和术后等效球面。
■视力从20/577提高到20/58。总的来说,实际的屈光度比预期的近视多0.06D。Holladay2,SandersRetzlaffKraff/理论界(SRK/T)和BarrettUniversalII导致轻度近视意外(-0.55,-0.18和-0.20D)。Haigis和Hill-RBF(径向基函数)导致轻度远视意外(0.28和0.28D)。HofferQ和Holladay1是最准确的(-0.02D和-0.08D)。
■带法兰的巩膜内人工晶体固定术可改善其他后段病变患者的视力。有效的晶状体定位可能类似于袋内定位。采用袋中计算的HofferQ和Holladay1公式是最准确的。
