白内障术后主导眼转换对视觉质量的影响

Effect of the exchanges of predominant eye on vision quality in patients after cataract surgery

目的分析白内障术后主导眼转换对视觉质量的影响。方法对该院2015年6月至2016年6月行晶状体超声乳化IOL植入术的258例(516眼),利用卡洞法判断主导眼,进行前瞻性研究。于术前及术后3个月测试患者主导眼视力变化及对比敏感度并询问患者手术满意度。结果术后3个月,有69例主导眼发生转换,转换率为26.74%;主导眼和非主导眼近视屈光度均较术前显著降低(P<0.05);在3cpd、6cpd、12cpd及18cpd空间频率,主导眼转换与未转换两组对比敏感度比较,差异无统计学意义(P>0.05);两组患者的术后满意度比较,差异无统计学意义(P>0.05)。结论白内障术后主导眼转换对视觉质量无明显影响。

Objective To analyze the effect of the exchanges of predominant eye on quality of vision in patients after cataract surgery. Methods A prospective study. The data of 516 eyes of 258 cases from Jun. 2015 to Jun.2016 were analyzed. All cases received phacoemulsification and intraocular lens implantation. The main predominant eye were determined with carving method. The visual acuity, contrast sensitivity and degree of satisfaction were observed before and 3 months after operation. Results At 3 months after operation, the predominant eye was exchanged in 69 cases(26.74%). The diopter of predominant eye and non-dominant eye were significantly decreased (P<0.05). The difference of contrast sensitivity of dominate eye in 3cpd, 6cpd, 12cpd and 18cpd were not statistically significant between exchanged eyes and unexchanged eyes (P>0.05). There was no significant difference in degree of satisfaction between the two groups (P>0.05). Conclusion There is no significant effect of the exchanges of predominate eye on vision quality after cataract surgery.
