摘　　要：目的探讨老年性白内障摘除术患者的视力情况及其相关影响因素。方法该研究中所有分析对象为方便选取2015年6月—2018年6月期间于该院进行临床治疗的96例老年性白内障摘除术后患者,并按照年龄阶段、术前角膜散光度情况、人工晶状体计算公式选择以及患者术后有无形成后发性白内障等不同统计内容对患者的术后视力水平进行分析,从而探究老年性白内障摘除术患者的视力情况及其相关影响因素。结果 96例患者术前视力为1.38±0.24,手术治疗1个月后,其平均视力为(0.58±0.14),(t=3.79,P<0.05)。与55~59岁年龄阶段患者相比,其他阶段患者视力水平改善程度较小,且随着患者年龄的提升,其术后视力改善越小(P<0.05)。与角膜中度散光患者相比,轻度散光或不散光患者,其术前、术后视力水平明显较高(P<0.05)。采用SRK-T公式与Holladay公式进行人工晶状体计算的患者,其术后视力水平相近(P>0.05);而采用Haigis-L公式的患者,其视力水平则明显优于采用其余两种公式的患者(P<0.05)。与术后形成后发性白内障患者相比,未形成后发性白内障的患者,其视力水平明显较高(P<0.05)。结论影响老年性白内障摘除术患者的视力情况的因素包括患者年龄、术前角膜散光度情况、人工晶状体计算公式选择以及患者术后有无形成后发性白内障等。Objective To investigate the visual acuity of patients with senile cataract extraction and its related influencing factors. Methods All the subjects in this study were 96 patients with senile cataract extraction who underwent clinical treatment in our hospital from June 2015 to June 2018. They were convenient calculated according to age, preoperative corneal astigmatism, and intraocular lens. The choice of formula and the presence or absence of postoperative cataract formation in patients with postoperative visual acuity were analyzed to explore the visual acuity of patients with senile cataract extraction and its related influencing factors. Results The preoperative visual acuity of the 96 patients was (1.38±0.24). After 1 month of operation, the average visual acuity was (0.58±0.14),(t=3.79, P<0.05). Compared with patients aged 55-59 years, the improvement of visual acuity in other stages was less, and the improvement of postoperative visual acuity was smaller as the patient's age increased(P<0.05). Compared with patients with corneal moderate astigmatism, the visual acuity of preoperative and postoperative patients was significantly higher in patients with mild astigmatism or non-astigmatism(P<0.05). In patients with intraocular lens calculations using the SRK-T formula and the Holladay formula, the postoperative visual acuity levels were similar(P>0.05). However, patients with the Haigis-L formula had significantly better visual acuity than those using the other two formulas(P<0.05). Compared with postoperative cataract patients, visual acuity was significantly higher in patients who did not develop posterior cataract(P<0.05). Conclusion The factors affecting the visual acuity of patients with senile cataract extraction include age, preoperative corneal astigmatism, choice of intraocular lens calculation formula and postoperative cataract formation.
