摘要：目的观察蓝光滤过型人工晶体植入术后视功能和视觉质量。方法随机选取老年性白内障患者，施行超声乳化术，实验组植入蓝光滤过型折叠人工晶体Acrysof Nature(SN60AT)，对照组植入一片式折叠人工晶体(SA60AT)，观察视力、眼压、角膜内皮细胞计数及并发症。结果两组在视力、眼压、角膜内皮、并发症等方面无显著性差异，但实验组患者术后无色觉改变、无蓝视症及眩光畏光。结论蓝光滤过型人工晶体能有效滤过蓝光，提高白内障患者术后视觉质量。

Abstract：Objective To observe the visual function and vision quality after blue-light filtering intraocular lens (Acrysof Nature) implantation. Methods The patients with age-related cataract treated with altrasonic phacoemulsification were randomly divided into two groups. The patients from treatment group were implanted with Acrysof Nature(SN60AT), while the patients from control group were implanted with single-piece intraccular lens (Acrysof). The visual acuity, IOP, corneal endothelial cell count and complication were observed. Results There were no significant differences in the aspects of visual acuity, IOP, corneal endothelial cell count and complication between treatment group and control group. But fewer people complained about color perception change, blue vision and glare in treatment group. Conclusion The blue-light filtering intraocular lens (Acrysof nature) can filter blue light effectively and improve the vision quality of patients with age-related cataract after intraocular lens implantation.

随着白内障超声乳化的广泛开展和技术的不断提高，术后植入折叠人工晶体(intraocular lens，IOL)使得白内障手术效果日臻完美，但是术后少数患者出现畏光、眩光、蓝视现象仍是影响视觉质量全面提高的常见因素。
Acrysof Nature是一种蓝色滤光型折叠人工晶体，能有效滤过蓝光，能减轻术后畏光、蓝视等症状，并对视网膜起到了保护作用，我们自2005年6月始应用此种人工晶体，并进行临床观察，现将结果报告如下。
1材料和方法
1.1一般资料
选取2005.6~2006.6在我院就诊的老年性白内障患者168例189眼，除外伤性白内障、并发性白内障等，随机分为两组，实验组 96例113眼，植入Acrysof Nature(SN60AT)人工晶体，对照组72例76眼，植入普通型Acrysof (SA60AT)人工晶体，术前进行眼AB超、角膜曲率、眼压、角膜内皮镜检查，并散瞳进行核分级(Emery分级标准)、眼底检查 ......
