目得：评价植入蓝光过滤人工透镜（IOL）和紫外线（UV）过滤IOL后视觉质量的潜在差异。单位：鲁尔大学眼科，波鸿，德国。设计：前瞻性随机队列研究。方法：年龄相关性白内障患者接受了双侧标准化小切口Kelman超声乳化白内障手术，并植入了蓝光-在一只眼睛中植入过滤IOL（Oculaid PC 440 Y橙子系列），在另一只眼睛中植入紫外线过滤IOL（Oculaid PC 430 Elite系列）。结果测量包括暗适应和明适应矫正远视力（CDVA）和明适应裸眼远视力（UDVA），辨色能力和有无眩光的对比敏感度。使用问卷调查评估患者满意度。术后随访时间分别为1、3、6个月。结果：22例患者（44只眼）完成了研究。两个IOL组之间的UDVA、CDVA或对比敏感度（有或无眩光）无统计学显著差异。除沿沿着红绿轴外，与紫外线滤光IOL相比，蓝光滤光IOL的眼睛的辨色能力显著降低（P= 0.118）。没有主观差异的颜色或光perception被发现。结论：两种IOL类型提供了类似的术后视觉功能，除了色觉，这是一个明确的IOL的眼睛稍好。尽管差异无临床显著性，但在植入橙子蓝色滤光IOL之前，可能会提供有关色觉潜在障碍的信息。
PURPOSE: To evaluate potential differences in the quality of vision after implantation of a blue light-filtering intraocular lens (IOL) and an ultraviolet (UV) light-filtering IOL.SETTING: Department of Ophthalmology, Ruhr-University, Bochum, Germany.DESIGN: Prospective randomized cohort study.METHODS: Patients with age-related cataract had bilateral standardized small-incision Kelman phacoemulsification-based cataract surgery with implantation of a blue light-filtering IOL (Oculaid PC 440Y Orange Series) in 1 eye and a UV light-filtering IOL (Oculaid PC 430 Elite Series) in the other eye. Outcome measures included scotopic and photopic corrected distance visual acuity (CDVA) and photopic uncorrected distance visual acuity (UDVA), color discrimination, and contrast sensitivity with and without glare. A questionnaire was used to assess patient satisfaction. Postoperative follow-up visits were scheduled at 1, 3, and 6 months.RESULTS: Twenty-two patients (44 eyes) completed the study. There were no statistically significant differences in UDVA, CDVA, or contrast sensitivity with or without glare between the 2 IOL groups. Color discrimination was significantly decreased in eyes with blue light-filtering IOLs compared with UV light-filtering IOLs, except along the red-green axis (P=.118). No subjective differences in color or light perception were found.CONCLUSIONS: Both IOL types provided similar postoperative visual function except color perception, which was slightly better in eyes with a clear IOL. Although differences were not clinically significant, information about potential disturbances in color vision might be provided before implanting an orange blue light-filtering IOL.
