Abstract:
UNASSIGNED: To analyze visual outcomes and accuracy of intraocular lens (IOL) calculation formulas in predicting postoperative outcomes in patients undergoing flanged intrascleral IOL fixation.
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.
摘要:
分析人工晶状体(IOL)计算公式在预测接受法兰巩膜内人工晶状体固定术的患者术后结果中的视觉结果和准确性。
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。
