摘要 目的观察非球面人工晶状体(IOL)和球面IOL植入术后在视力相同的情况下其对比敏感度的差异。方法收集行超声乳化联合IOL植入术的年龄相关性白内障患者49例(60眼),其中植入非球面IOL Tecnis ZA9003者24例30眼,植入球面IOLSensar AR40e者25例30眼,所有病例术后裸眼LogMAR视力均>0.1。术后3个月时采用CSV-1000对比敏感度测试仪分别测量明视、暗视和眩光状态下的对比敏感度,用F.A.C.T对比敏感度表测量近距离对比敏感度。结果在明视和暗视状态下的对比敏感度,非球面IOL组均高于球面IOL组,两组在空间频率6、12、18周/度时的差异均有统计学意义(P<0.05);暗视眩光状态下的对比敏感度,非球面IOL组高于球面IOL组,两组在各空间频率的差异均有统计学意义(P<0.05)。F.A.C.T对比敏感度测试卡测得的对比敏感度,非球面IOL组高于球面IOL组,两组在各空间频率的差异均有统计学意义(P<0.05)。结论在传统的视力表检查视力正常和相同的情况下,非球面IOL植入术后较球面IOL植入术后患眼具有较好的对比敏感度,提示非球面IOL可以提高功能视力。 Objective Contrast sensitivity is well known as an index of functional vision. The goal of this study was to assess and compare the functional vision in patients with aspheric and spherical intraocular lens implantation. Methods A retrospective study on consecutive cases with age-related cataract underwent phacoemulsification and aspheric intraoeular lens Teenis ZA9003 or spherical intraocular lens Sensar AR40e implantation was carried out. The 49 patients (60 eyes) following operation without intraoperative or postoperative complications were enrolled in this study. Standardized ocular examination and contrast sensitivity under the different conditions and spatial frequencies were performed on the eyes with naked LogMAR visual acuity over 0. 1 at 3 months after operation. The clinical data from 30 eyes (24 cases) with aspheric intraocular lens Tecnis ZA9003 and 30 eyes (25 cases) with spherical intraocular lens Sensar AR40e was analyzed and compared. Results No significant difference was found in the age, gender and postoperative LogMAR vision between two groups(P〉0.05 ). The photopic and scotopic contrast sensitivities at the spatial frequency of 6,8,12 cp/d were significantly improved in the eyes with aspheric intraocular lens Tecnis ZA9003 in comparison with the eyes with spherical intraoeular lens Sensar AR40e implantation (P 〈0.05). Glare and FACT contrast sensitivity was obviously better in the eyes with aspherie intraocular lens Teenis ZAg003 at various spatial frequencies( 3,6,12,18 cp/d) than eyes with spherical intraocular lens Sensar AR40e implantation( P 〈 0. 05 ). Conclusion Aspheric intraocular lens Tecnis can improve the functional vision of pseudophakia in comparison with conventional spherical intraocular lens.
