【摘要】：目的通过分析计算不同晶体消除球面相差的差值,研究白内障患者行白内障超声乳化联合多焦点非球面人工晶状体的临床疗效。方法临床纳入2016年01月至2016年05月间收治的老年性白内障患者180例(180只眼),按入院顺序分为3组,各60例。其中植入Re STOR-SN60D3晶体者60例设为多焦非球面组(SN60D3组),植入SN60AT晶体者60例设为单焦球面组(SN60AT组),植入SN60WF晶体者60例设为单焦非球面组(SN60WF组)。术后3个月观察术眼的屈光状态、焦点深度、调制解调函数值MTF,测量高阶像差,并问卷调查视觉质量。结果术前3组患者视力情况无明显差异(P0.05),术后SN60D3组的UCNVA明显优于SN60AT组和SN60WF组(P0.05);在3 mm瞳孔直径下,术后SN60D3组与SN60WF组的球差Z(4,0)均小于SN60AT组(P0.05),术后SN60D3组与SN60WF组仅在5cpd空间频率下MTF(HOA)值优于SN60AT组(P0.05);术后SN60D3组患者在近视力、对矫正视力的依赖、活动是否受限等方面得分均高于其他两组(P0.05),在视觉清晰度方面及白天视力波动情况好于单焦球面组(P0.05)。结论多焦点非球面人工晶状体全眼总的球差及高阶像差更小,裸眼近视力效果更佳,其余视力稳定,可为白内障患者术后提供良好的视觉质量。
[Abstract]:Objective through the analysis and calculation of different crystal difference to eliminate spherical aberration, study of cataract phacoemulsification with multifocal non spherical intraocular lens. The clinical curative effect in 180 patients with senile cataract from 2016 01 to 2016 05 months from clinical cases (180 eyes), were randomly divided into 3 groups, each 60 the implantation of Re crystal STOR-SN60D3 cases. 60 cases for multifocal aspheric group (SN60D3 group), the implantation of SN60AT crystal in 60 cases for the single focal sphere group (SN60AT group), the implantation of SN60WF crystal in 60 cases for the single focal aspheric group (SN60WF group). Observed the refractive state of the eye. 3 months after the depth of focus, modulation and demodulation function value MTF, high order aberration and visual quality measurement, questionnaire survey. Results there were no significant differences between the 3 groups of patients with preoperative visual acuity (P0.05), SN60D3 after operation of group UCNVA was significantly better than that of SN60AT group and SN60WF group (P0.05); in 3 mm The pupil diameter, spherical aberration Z SN60D3 group and SN60WF group after surgery (4,0) were less than group SN60AT (P0.05), SN60D3 group and SN60WF group only MTF in 5cpd spatial frequency after operation (HOA) is better than SN60AT group (P0.05); group SN60D3 patients in the near vision, dependent on vision correction whether the activity is limited and so on, scores were higher than the other two groups (P0.05), in the visual clarity and vision during the day volatility is better than single focal sphere group (P0.05). Conclusion multifocal aspheric intraocular lens total ocular spherical aberration and high-order aberration is smaller, uncorrected near visual acuity better, the visual acuity stable can provide good visual quality of cataract patients after surgery.
