白内障摘除联合非球面散光矫正型多焦点人工晶状体植入术的疗效

目的：研究白内障患者行白内障摘除联合非球面散光矫正型多焦点人工晶状体( IOL)植入术的临床疗效。
　　方法：临床纳入我院2014-02/2015-03期间收治的白内障患者86例86眼,按入院顺序分为两组,各43例。其中43例患者采用白内障摘除联合非球面散光矫正型单焦点IOL植入术治疗作为对照组,另43例患者采用白内障摘除联合非球面散光矫正型多焦点IOL植入术治疗作为观察组。术后随访患者1a,观察两组患者视力情况、散光情况以及不同空间频率下对比敏感度情况。
　　结果：术前两组患者视力情况无统计学差异(P>0.05)；术后观察组患者UCNVA明显优于对照组,差异有统计学意义(P<0.05),其余指标无统计学差异(P>0.05)。手术前后两组患者散光情况均无统计学差异(P>0.05)。术前两组患者对比敏感度无统计学差异(P>0.05)；术后对照组在18、24 c/d空间频率上对比敏感度优于观察组,差异有统计学意义(P<0.05),其余无统计学差异(P>0.05)。
　　结论：散光矫正多焦点人工晶状体对角膜散光的患者术后有较好效果,裸眼近视力效果更佳,其余视力较稳定,视觉质量良好。

Clinical observation of cataract extraction combined with intraocular lens implantation in the treatment of multifocal intraocular lens

AIM: To study the clinical effect of implantation of multifocal intraocular lens(IOL)combined with cataract extraction and IOL in cataract patients.

METHODS:A total of 86 cases(86 eyes)of cataract patients admitted to our hospital from Feb. 2014 to Mar. 2015 were divided into two groups according to the order of admission, each of 43 cases. The 43 patients with cataract extraction combined with non spherical astigmatism correction type monofocal IOL implantation for the treatment as the control group, the other 43 patients with cataract extraction combined with aspheric toric multifocal IOL implantation were treated as the observation group. After 1y of follow-up, the visual acuity, astigmatism and the contrast sensitivity of the two groups were observed.

RESULTS:There was no difference in visual acuity between two groups(P>0.05). Postoperative observation group of uncorrected near visual acuity(UCNVA)was significantly better than the control group(P<0.05), and the other indexes were not different(P>0.05). There was no difference in astigmatism between the two groups before and after operation(P>0.05). There was no difference in contrast sensitivity between two groups(P>0.05). The contrast sensitivity of the control group was better than that of the observation group(P<0.05), and the rest had no difference(P>0.05).

CONCLUSION:Astigmatism correction multifocal intraocular lens on corneal astigmatism after surgery has a good effect, the naked eye near visual effect is better, the rest of the visual acuity is stable, good visual quality, worthy of clinical application and promotion.
