衍射型非球面多焦点IOL在维吾尔族白内障超乳术中的应用

目的：研究衍射型非球面多焦点人工晶状体在维吾尔族白内障超声乳化联合术中的应用效果及安全性,为新疆喀什地区白内障患者的临床治疗提供指导意义。
　　方法：选取2012-04/2013-03期间施行白内障超声乳化联合术的维吾尔族患者228例280眼,随机分为多焦点组(106例146眼)和单焦点组(122例134眼)。术后随访3lo,测量患者的眼压、裸眼远视力、裸眼近视力、最佳矫正远视力以及最佳矫正近视力,通过调查问卷的形式对患者的脱镜率、视觉质量以及对人工晶状体的满意度进行比较。
　　结果：多焦点组裸眼近视力明显优于单焦点组,差异有统计学意义(P<0.05)。两组裸眼远视力、最佳矫正远视力、最佳矫正近视力差异无统计学意义( P>0.05)。多焦点组在暗光条件下空间频率3c/d的对比敏感度低于单焦点组,差异有统计学意义(P<0.05),其余差异均无统计学意义(P>0.05)。多焦点组脱镜率明显高于单焦点组,两组差异有统计学意义(P<0.05)。两组患者术后满意度之间的差异无统计学意义(P>0.05) 。
　　结论：衍射型非球面多焦点IOL联合白内障超声乳化可为患者提供较好的全程视力,尤其在近视力方面表现良好,患者具有较高的脱镜率,术后不良症状较少,恢复快,患者满意度高。

Application of diffractive aspheric multifocal intraocular lens in the Uighur in phacoemulsification

AIM:To research the efficacy and safety of diffractive aspheric multifocal intraocular lens(MIOL)in the Uighur in phacoemulsification to provide guidance for the clinical treatment of cataracts patients in Xinjiang region.

METHODS:Two hundred and twenty-eight Uygur patients(280 eyes)received phacoemulsification from April 2012 to March 2013 were randomly divided into multifocal group(106 cases with 146 eyes)and monofocal group(122 cases with 134 eyes). Patients were followed up for 3mo. The intraocular pressure(IOP), uncorrected distance visual acuity, uncorrected near vision, best-corrected distance visual acuity and best corrected near vision were measured. The delensed rate, visual quality, and satisfaction for lenses in the form of questionnaires were compared.

RESULTS:Multifocal group was better on the uncorrected near vision than monofocal group(P<0.05).The differences on uncorrected distance visual acuity, best corrected distance visual acuity, best corrected near vision between the two groups showed no significant difference(P>0.05). The contrast sensitivity of multifocal group under scotopia at spatial frequency 3c/d was lower than that of monofocal group(P<0.05), those at other spatial frequency had no difference(P>0.05). Delensed rate of multifocal group was higher than that of monofocal group(P<0.05). The satisfaction for lenses had no difference between the two groups(P>0.05).

CONCLUSION:MIOL with phacoemulsification can provide patient good full range vision, especially on good near vision. The patients with MIOL implanted have a higher delensed rate, less postoperative adverse symptoms, quicker recovery and satisfaction.
