To evaluate distance, intermediate, and near visual performance in patients who had multifocal apodized diffractive intraocular lens (IOL) implantation.
Fernández-Vega Ophthalmological Institute, Oviedo, Spain.
The best corrected distance visual acuity, best distance-corrected near visual acuity, intermediate visual acuity, distance contrast sensitivity under photopic and mesopic conditions, and patient satisfaction were measured in 325 patients and 335 patients who had bilateral implantation of the model SA60D3 IOL (AcrySof ReSTOR, Alcon) and model SN60D3 IOL (AcrySof Natural ReSTOR), respectively.
At the 6-month postoperative visit, binocular best corrected distance acuity with the ReSTOR IOL and the Natural ReSTOR IOL was 0.034 logMAR+/-0.004 (SD) and 0.019+/-0.020 logMAR, respectively (approximately 20/20). Binocular best distance-corrected near acuity was 0.011+/-0.012 logMAR and 0.035+/-0.013 logMAR, respectively (approximately 20/20). Intermediate visual acuity with both IOL models worsened significantly as a function of the distance of the test (P<.01). Photopic contrast sensitivity was within the standard normal range with both IOLs. Under mesopic conditions, contrast sensitivity with both IOLs was comparable to that with monofocal IOLs and lower, particularly at higher spatial frequencies, than under photopic conditions. No statistically significant differences in visual acuity or photopic and mesopic contrast sensitivity were found between the 2 IOL models (P>.1). A patient satisfaction questionnaire showed that both IOLs performed well and were comparable in satisfaction regarding distance, intermediate, and near activities under different lighting conditions.
The AcrySof ReSTOR IOL and AcrySof Natural ReSTOR IOL provided good visual performance at distance and near under photopic and mesopic conditions. Intermediate vision with both models was reduced compared with distance and near vision.
评估植入多焦点变迹衍射人工晶状体（IOL）患者的远、中、近视力表现。
西班牙奥维耶多的费尔南德斯 - 维加眼科研究所。
分别对325例双侧植入SA60D3型IOL（爱尔康公司的AcrySof ReSTOR）和335例双侧植入SN60D3型IOL（AcrySof Natural ReSTOR）的患者测量最佳矫正远视力、最佳远矫正近视力、中视力、明视和微光条件下的远对比敏感度以及患者满意度。
术后6个月随访时，使用ReSTOR IOL和Natural ReSTOR IOL的双眼最佳矫正远视力分别为0.034 logMAR±0.004（标准差）和0.019±0.020 logMAR（约20/20）。双眼最佳远矫正近视力分别为0.011±0.012 logMAR和0.035±0.013 logMAR（约20/20）。两种IOL模型的中视力均随测试距离增加而显著下降（P<0.01）。两种IOL的明视对比敏感度均在标准正常范围内。在微光条件下，两种IOL的对比敏感度与单焦点IOL相当，但低于明视条件下，尤其是在较高空间频率时。两种IOL模型在视力、明视和微光对比敏感度方面无统计学显著差异（P>0.1）。患者满意度调查问卷显示，两种IOL表现良好，在不同光照条件下的远、中、近活动满意度相当。
AcrySof ReSTOR IOL和AcrySof Natural ReSTOR IOL在明视和微光条件下提供了良好的远、近视力表现。与远、近视力相比，两种模型的中视力均有所下降。
