双眼植入非球面人工晶状体和传统球面人工晶状体的临床比较

Clinical comparison of bilateral implantation of aspheric intraocular lens and spherical intraocular lens

目的观察植入非球面人工晶状体和传统球面人工晶状体的临床效果。方法选取我院收治的55例老年性白内障患者,按处理方法不同分为两组,观察组25例患者植入非球面人工晶状体;对照组30例患者植入传统球面人工晶状体。结果观察组手术1周后患眼视力明显高于手术前,对照组手术1个月后明显高于手术前,观察组术后患眼视力恢复情况明显好于对照组(P<0.05);手术后1个月和3个月,观察组患者的四阶球差和高阶像差都低于对照组,差异具有统计学意义(P<0.05),且两组患者最佳矫正视力下的远、近立体视觉比较,差异具有统计学意义(P<0.05)。结论非球面人工晶状体植入治疗白内障能够显著地减少球面像差,提高对比敏感度,改善手术后的视觉质量,值得临床推广应用。

Objective To observe the clinical effect of implantation of aspheric intraocular lens and spherical intraocu- lar lens. Methods A total of 55 patients with senile cataract patients in our hospital, which were divided into two groups, the observation group of 25 cases patients with implantation of aspheric intraocular lens while the control group of 30 patients with traditional spherical intraocular lens implantation. Results The observation group after opera- tion a week eyesight was significantly higher than that of control group before operation, after operation in January was significantly higher than that before operation, postoperative visual acuity recovery in observation group was signifi- cantly better than the control group （P 〈 0.05）, operation after one month and three months, patients in the observation group of four order spherical aberration and high higher-order aberrations were lower than those of the control group, the difference was statistically significant （P 〈 0.05）, the two groups of patients with the best corrected visual acuity of far stereo vision, in comparison, the difference was statistically significant （P 〈 0.05）. Conclusion Aspheric intraocular lens implan- tation for cataract can significantly reduce the spherical aberration, improve contrast sensitivity after operation, improve the visual quality, worthy of clinical application.
