目的探讨滤蓝光人工晶体在老年性白内障治疗中的作用。方法51例老年性白内障患者行超声乳化白内障吸出术,26例(26只眼)白内障患者植入滤蓝光人工晶体(试验组),25例(26只眼)植入普通折叠式人工晶体(对照组)。观察患者术后视力、对比敏感视力、中心30度视敏度、周边60度视敏度及手术并发症,随访时间3个月。结果术后3个月视力≥0.5试验组92.3%,对照组84.6%,差异无显著意义(P>0.05);对比敏感视力40%对比值时,试验组为0.20±0.05,对照组0.20±0.06,差异无显著意义(P>0.05);30度视敏度试验组为(25.79±1.98)DB,对照组为(25.72±1.96)DB,周边60度视敏度试验组(17.78±2.07)DB,对照组(17.32±2.18)DB,差异无显著意义(P>0.05)。对照组中有一例术中后囊破裂。结论滤蓝光人工晶体植入术治疗老年性白内障是安全、有效的,其近期临床效果类同普通折叠式人工晶体,但是,从远期疗效看,滤蓝光人工晶体可能为患者提供更好的视网膜保护作用。
Objective To investigate the role of blue photorefractive lens in the treatment of senile cataract. Methods 51 cases of senile cataract patients underwent phacoemulsification cataract extraction, 26 cases (26 eyes) of cataract patients were implanted with filter blue intraocular lens (experimental group) and 25 cases (26 eyes) were implanted with ordinary foldable intraocular lens group). Visual acuity, contrast sensitivity, center visual acuity of 30 degrees, peripheral visual acuity of 60 degrees and surgical complications were observed. The follow-up time was 3 months. Results The visual acuity ≥ 0.5 at 3 months after operation was 92.3% in the test group and 84.6% in the control group, with no significant difference (P> 0.05). When the contrast sensitivity was 40%, the test group was 0.20 ± 0.05 while the control group was 0.20 ± 0.06 (25.79 ± 1.98) DB in the 30-degree visual acuity test group, (25.72 ± 1.96) DB in the control group and 17.78 ± 2.07 DB in the 60-degree peripheral visual acuity test group (P> 0.05) , While the control group (17.32 ± 2.18) DB, the difference was not significant (P> 0.05). In the control group, there was a case of posterior capsule rupture. Conclusions Filter blue intraocular lens implantation for the treatment of senile cataract is safe and effective, and its clinical effect is similar to that of ordinary foldable intraocular lens in the near future. However, in terms of long-term therapeutic effect, blue photorefractive lens may provide a better retina for patients Protective effects.
