目的分析3.2mm透明角膜切口白内障超声乳化吸除及折叠式人工晶状体植入术后患者的屈光状态及其变化规律。方法老年性白内障患者68例(118只眼)行3.2mm透明角膜切口白内障超声乳化吸除及折叠式人工晶状体植入术后第1、2、3、4周、第3个月行视力及验光检查,记录患者的视力、球镜、柱镜和散光轴,分别对结果行多因素方差分析。结果术后第1、2、3、4周、第3个月的裸眼及矫正视力,球镜、柱镜度数及其散光轴的变化差异均无统计学意义(P>0.05)。结论3.2mm透明角膜切口白内障超声乳化吸除及折叠式人工晶状体植入术后1周屈光状态基本趋于稳定。
Objective To analyze the refractive status and its variation of 3.2mm clear corneal incision phacoemulsification and foldable intraocular lens implantation. Methods A total of 68 patients (118 eyes) with senile cataract underwent 3.2mm clear corneal incision phacoemulsification and foldable intraocular lens implantation at 1, 2, 3, and 4 weeks after operation. Visual acuity and optometry Check, record the patient’s vision, spherical, cylinder and axis of astigmatism, respectively, the results of multiple-factor analysis of variance. Results There was no significant difference in visual acuity, spherical degree, lemmanometer and astigmatism axis between the 1st, 2nd, 3rd, 4th week and 3rd month postoperatively (P> 0.05). Conclusion 3.2mm clear corneal incision phacoemulsification and foldable intraocular lens implantation 1 week after the refraction basically stabilized.
