Abstract

Purpose: To evaluate the efficacy and safety of a newly developed diffractive multifocal intraocular lens (IOL) with +2.5 diopter near add power (SN6AD2, Alcon), whose theoretical distance for near focus is 50 cm.

Methods: This study included 128 eyes of 64 patients (23 men and 41 women, average age: 66.7 ± 7.2 years) following cataract removal at Tokyo Dental College Suidobashi Hospital and Hayashi Eye Hospital. Visual acuities (VAs) at distance, 1 m, 50 cm and 40 cm, and questionnaires were evaluated until 1 year postoperatively.

Results: At 1 year postoperatively, mean bilateral logMAR VAs were uncorrected -0.09 (5 m), 0.01 (1 m), 0.07 (50 cm), 0.18 (40 cm), distance corrected 0.01 (1 m), 0.08 (50 cm), 0.19 (40 cm), best corrected -0.17 (5 m), 0.00 (50 cm). From the patient's questionnaires, light or moderate glare was noticed in 17.5%, 4.8%, light or moderate halo was notice in 19.0%, 4.8% of the total patients.

Conclusion: This IOL provides good distance to intermediate VAs and better near VA compared to monofocal IOL.

[有色非球面多焦人工晶状体+2.5屈光度近加力SN6AD2 (SV25T0)的临床结果]。

目的:评价新研制的近焦理论距离为50 cm的+2.5屈光度衍射多焦人工晶状体(SN6AD2, Alcon)的疗效和安全性。方法:在东京齿科大学水桥医院和林桥眼科医院行白内障摘除手术的患者64例，128眼，男23例，女41例，平均年龄66.7±7.2岁。随访至术后1年，分别进行距离、1 m、50 cm、40 cm的视力(VAs)及问卷调查。结果:术后1年，平均双侧logMAR VAs未矫正为-0.09 (5 m)、0.01 (1 m)、0.07 (50 cm)、0.18 (40 cm)，距离矫正为0.01 (1 m)、0.08 (50 cm)、0.19 (40 cm)，最佳矫正为-0.17 (5 m)、0.00 (50 cm)。从患者的问卷中，发现轻度或中度眩光的占17.5%，4.8%;轻度或中度晕光的占19.0%，4.8%。结论:与单焦点人工晶状体相比，该人工晶状体距中间人工晶状体较远，距近人工晶状体较好。
