三焦点人工晶体植入术后一年随访

360度直角方边设计,提供后囊面PCO保护。

摘要

目的
评估三焦点植入术后一年,视力、屈光结果、对比敏感度及像差的跟踪结果。
环境
高端诊所,捷克。
设计
具有前瞻性。
方式
此研究所选用均为白内障术后植入蔡司三焦点患者。在术后12个月的随访中进行了包括远、中(66-80cm)、近距离(33-40cm)视力测试、对比敏感度、像差及离焦曲线的检查。
结果
60名患者120只术眼术后1个月显示所有患者远中近视力均有显著提升。在术后1-12个月中的观察表明最佳矫正及未矫正远视力、近视力、中视力均有些微但显著且令人满意的提升。离焦曲线研究中,各距离视力对应的散焦1D-2D之间未发现明显不同。在6个月后观察球差明显减少,内部高阶像差在术后6-12个月有轻微增加。后发障12个月后评分为0.32G,120只眼有4只需要YAG激光治疗。
结论

术后一年随访结果提示,蔡司三焦点人工晶体能提供长期稳定的全程视力,并带来良好的视觉质量。

Abstract

PURPOSE
To evaluate the visual, refractive, contrast-sensitivity, and aberrometric outcomes during a 1-year follow-up for an implantation of a trifocal intraocular lens.
SETTING
Premium Clinic,Teplice, Czech Republic.
DESIGN
Prospective case series.
METHOD
This study included eyes of patients having cataract surgery with implantation of the trifocal IOL model AT LISA tri 839MP. Distance, intermediate (66 and 80 cm), and near (33 and 40 cm) vision, contrast sensitivity, and aberrometric outcomes, and the defocus curve were evaluated during a 12-month follow-up. The level of posterior capsule opacification (PCO) was also evaluated.
RESULTS
In 120 eyes (60 patients), at 1 month postoperatively, an improvement was observed in all visual parameters (P%.03) except corrected near and intermediate visual acuities (PR.05 for both). From 1 month to 12 months postoperatively, small but statistically significant changes were observed in uncorrected and corrected distance and near visual acuities (P%.03 for all 4 acuities) and in uncorrected intermediate visual acuity (PZ .01). In the defocus curve, no significant differences were found between visual acuities corresponding to defocus levels of _1.0 and _2.0 diopters (P Z .22). The level of ocular spherical aberration decreased statistically significantly at 6 months (P < .001). Ocular and internal higher-order aberrations increased minimally but significantly from 6 to 12 months postoperatively (P < .001). The mean 12-month PCO score was 0.32 G 0.44 (SD). Four eyes (3.3%) required neodymium: YAG capsulotomy.
CONCLUSION
The trifocal IOL provided complete and stable visual restoration after cataract surgery during a 12-month follow-up, with good levels of visual quality.
