To compare visual acuity after bilateral implantation of 2 models of multifocal aspheric intraocular lenses (IOLs).
Fernández-Vega Ophthalmological Institute, Oviedo, and University of Valencia, Valencia, Spain.
Prospective study of patients who had bilateral implantation of an AcrySof ReSTOR SN6AD3 IOL (Group 1) or an Acri.LISA 366D IOL (Group 2). Six months postoperatively, binocular uncorrected and best corrected distance visual acuity, uncorrected-distance and best distance-corrected near visual acuity, best corrected intermediate visual acuity, and the defocus curve were measured in both IOL groups.
Group 1 comprised 36 eyes (18 patients) and Group 2, 40 eyes (20 patients). The mean binocular values in Group 1 and Group 2, respectively, were as follows: best corrected distance acuity, -0.05 +/- 0.09 logMAR and -0.08 +/- 0.08 logMAR (both approximately 20/20); best distance-corrected near acuity, -0.01 +/- 0.16 logMAR and -0.05 +/- 0.07 logMAR; best corrected intermediate acuity at 80 cm, 0.20 +/- 0.18 logMAR (approximately 20/32) and 0.16 +/- 0.13 logMAR (approximately 20/25) and at 60 cm, 0.16 +/- 0.16 logMAR (approximately 20/25) and 0.18 +/- 0.13 logMAR (approximately 20/25). There were no statistically significant between-group differences in visual acuity at any distance (P>.3). Defocus curves were similar between groups (2.00 to -5.00 diopters) (P>.26).
The 2 multifocal aspheric IOL models gave similar and good high-contrast visual acuity at distance and near. Intermediate visual acuity, also comparable between IOL models, was better than published results of a spherical IOL model.
比较两种多焦点非球面人工晶状体(IOL)双侧植入后的视力。
西班牙奥维耶多的费尔南德斯 - 维加眼科研究所和巴伦西亚大学。
对双侧植入AcrySof ReSTOR SN6AD3 IOL(第1组)或Acri.LISA 366D IOL(第2组)的患者进行前瞻性研究。术后6个月,测量两组IOL患者的双眼未矫正和最佳矫正远视力、未矫正远视力和最佳远矫正近视力、最佳矫正中视力以及散焦曲线。
第1组包括36只眼(18例患者),第2组包括40只眼(20例患者)。第1组和第2组的平均双眼值分别如下:最佳矫正远视力,-0.05±0.09 logMAR和-0.08±0.08 logMAR(均约为20/20);最佳远矫正近视力,-0.01±0.16 logMAR和-0.05±0.07 logMAR;80 cm处最佳矫正中视力,0.20±0.18 logMAR(约为20/32)和0.16±0.13 logMAR(约为20/25),60 cm处为0.16±0.16 logMAR(约为20/25)和0.18±0.13 logMAR(约为20/25)。在任何距离的视力上,两组之间均无统计学显著差异(P>.3)。两组之间的散焦曲线相似(2.00至-5.00屈光度)(P>.26)。
这两种多焦点非球面IOL模型在远视力和近视力方面提供了相似且良好的高对比度视力。IOL模型之间的中视力也相当,优于已发表的球面IOL模型的结果。
