目的：比较佩戴 AcrySof 天然人工晶状体 (IOL)（爱尔康实验室公司）的眼睛和佩戴 AcrySof IOL 的另一只眼睛之间的最佳远视力、色觉和对比敏感度，并将 IOL 组的结果与正常、年龄相仿的透明晶状体眼患者的结果进行比较。 地点：印度古瓦哈蒂的 Sri Sankaradeva Nethralaya。 方法：该前瞻性随机平行组单中心患者蒙蔽检查员掩蔽研究包括 13 名患有双眼年龄相关性白内障的健康患者的 26 只眼睛。所有患者均进行双眼白内障超声乳化手术；我的眼睛接受了 AcrySof 自然 IOL (SN60AT)，另一只眼睛接受了 AcrySof (SA60AT) IOL。 18个月末进行最终术后检查。除了其他发现之外，还记录了视力、色觉和对比敏感度。检查一组正常、年龄相近、佩戴透明晶状体的有晶状体眼个体的对比敏感度。对所得记录进行统计分析。 结果：与术前状态相比，AcrySof 和 AcrySof Natural IOL 组在视力和色觉方面有统计学上显着的改善，并且这种情况一直保持到术后 18 个月的最后一次随访。 2 个 IOL 组之间的结果没有统计学上的显着差异。从术前到术后，AcrySof 和 AcrySof Natural IOL 组的对比敏感度均显着改善（均 P
PURPOSE: To compare best distance visual acuity, color perception, and contrast sensitivity between eyes with an AcrySof Natural intraocular lens (IOL) (Alcon Laboratories Inc.) and fellow eye with an AcrySof IOL and to compare results in the IOL groups to those in normal, similarly aged patients with clear phakic eyes.SETTING: Sri Sankaradeva Nethralaya, Guwahati, India.METHODS: This prospective randomized parallel group single-center patient-masked examiner-masked study comprised 26 eyes of 13 healthy patients with bilateral age-related cataract. All patients had cataract surgery by phacoemulsification in both eyes; I eye received an AcrySof Natural IOL (SN60AT) and the fellow eye, an AcrySof (SA60AT) IOL. Final postoperative examination was performed at the end of 18 months. In addition to other findings, visual acuity, color perception, and contrast sensitivity were recorded. A group of normal, similarly aged phakic individuals with clear lenses was examined for contrast sensitivity. The records thus obtained were analyzed statistically.RESULTS: The AcrySof and AcrySof Natural IOL groups had a statistically significant improvement in visual acuity and color perception in comparison to preoperative status, and this was maintained until the last postoperative follow-up at 18 months. There was no statistically significant difference in the findings between the 2 IOL groups. The AcrySof and the AcrySof Natural IOL groups showed significant improvement in contrast sensitivity from the preoperative to the postoperative period (both P
