目的:分析白内障超声乳化吸出并散光矫正型多焦点人工晶状体(IOL)植入术对白内障患者角膜散光及视觉质量的影响。
方法:将2016-12/2018-02因白内障于我院进行眼科手术治疗的95例95眼患者作为研究对象。对所有对象进行随机分组对比研究,两组均行白内障超声乳化吸出术治疗,对照组联合散光矫正型单焦点人工晶状体植入术治疗; 观察组联合散光矫正型多焦点人工晶状体植入术治疗。对比两组角膜散光、视觉质量及视力改善程度的差异。
结果:随访3mo,两组治疗后非矫正远视力、最佳矫正远视力、非矫正近视力及最佳矫正近视力均显著改善,观察组改善程度显著高于对照组(P<0.05); 治疗后两组角膜散光情况显著改善(P<0.05),组间改善程度无显著差异(P>0.05); 治疗后两组视觉对比敏感度均显著升高(P<0.05),观察组18c/d空间频率下视觉对比度显著低于对照组(P<0.01)。术后1d,观察组患者仅2眼出现角膜内皮水肿,对照组患者仅1眼出现角膜内皮水肿,观察组与对照组并发症发生率无显著差异(P>0.05)。
结论:超声乳化吸出并散光矫正型多焦点IOL植入术治疗白内障,可有效矫正视力,降低角膜散光,提高其视觉对比度,整个手术治疗过程安全性较高,术后并发症少。

[Abstract]
AIM:To analyze the effect of phacoemulsification and astigmatism corrected multifocal intraocular lens(IOL)implantation on corneal astigmatism and visual quality in cataract patients.
METHODS:Ninety-five patients who underwent ophthalmic surgery in our hospital for cataract disease between December 2016 and February 2018 were studied. All subjects were randomized and compared. Both groups were treated with phacoemulsification. The control group was treated with astigmatism-corrected monofocal intraocular lens implantation. The observation group was combined with astigmatism-corrected multifocal intraocular lens implantation. The differences in corneal astigmatism, visual quality, and vision improvement were compared between the two groups.
RESULTS: Uncorrected distance vision, best corrected distance vision, uncorrected near vision and best corrected near vision were significantly improved in the two groups after treatment at 3mo after operation. The degree of improvement in the observation group was significantly higher than that in the control group(P<0.05). The corneal astigmatism of the two groups was significantly improved after treatment(P<0.05). There was no significant difference between the two groups(P>0.05). After the treatment,the visual contrast sensitivity was significantly increased(P<0.05). The visual contrast at the 18 cpd spatial frequency in the observation group was significantly lower than that in the control group(P<0.01).One day after surgery, only two eyes in the observation group showed corneal endothelial edema, and only one eye in the control group showed corneal endothelial edema. There was no significant difference in the incidence of complications between the observation group and the control group(P>0.05).
CONCLUSION: The treatment of cataract patients with phacoemulsification and astigmatism-corrected multifocal IOL implantation can effectively correct vision, reduce corneal astigmatism, and improve visual contrast. The entire surgical procedure is safe and has fewer postoperative complications.
