高度轴性近视眼白内障患者术后视力的预测

Forecast of Visual Acuity in Cataract Patients with Highly Axial Myopia

目的分析高度轴性近视眼白内障患者影响术后视力的相关因素。方法选择眼轴长度≥26mm的高度轴性近视眼白内障患者41例(58眼)为研究对象。测量眼轴长度、术前视力、潜视力(PVA),检查眼底视网膜病变程度。行超声乳化吸除和人工晶体植入术后,测最佳矫正视力(BCVA)。结果所有患者术后视力都有不同程度的提高。经χ2检验,眼轴长度、PVA对术后BCVA的影响有统计学意义(P<0.01)。多元回归分析的结果显示,眼底视网膜病变越重,术后BCVA越差(P<0.01)。结论眼轴长度、PVA、眼底视网膜病变程度是影响术后视力的主要因素。

Objective To analyze the influential factors of visual acuity after surgery in cataract patients with highly axial myopia. Methods Fifty-eight eyes of 41 patients with highly axial myopic cataract whose length of ocular axes not shorter than 26 mm were selected. The length of ocular axes, visual acuity before surgery, potential visual acuity (PVA), degree of ocular fundus retinopathy and best corrected visual acuity (BCVA) after surgery were examined. Results The visual acuity after surgery was improved in all patients. According to χ 2 test and multiple regression analysis, the length of ocular axes, PVA and degree of ocular fundus retinopathy had significant influence on BCVA after surgery (P<0.01). Conclusion The length of ocular axes, PVA, and degree of ocular fundus retinopathy are the key influencing factors of visual acuity after surgery.
