摘要
目的评估依照晶状体混浊程度不同采用不同的检查项目来预测术后视力的准确性、有效性和实用性。方法对348例358眼不同类型白内障患者在手术前按依照LOCSII晶状体混浊分类标准进行分级且分A、B两组,分别做相关检查项目。A组散瞳前置镜眼底检查、视网膜计潜视力(PVA)检查,A超测量眼轴长度;B组闪光视网膜电图(F-ERG),闪光视诱发电位(F-VEP),眼科A超眼轴长度的测量得出术后预测视力,并将其与术后4周最佳矫正视力(BCVA)对照并做统计分析。结果 348例358眼白内障患者术前检查预测术后视力和术后4周最佳矫正视力(BCVA)基本符合,且A、B两组间差异无统计学意义,术前检查项目与术后BCVA之间均存在正线性相关。结论白内障分组术前检查能准确、有效、快速地预测白内障手术后视力。
Objective To investigate the value of preoperative examination of lens opacity degree in prediction of postop-erative visual acuity. Methods Total 358 eyes （348 cases ） with different types of cataract were enrol ed,according to LOCS Ⅱthe lens opacities were classified and the cases were divided into two groups： in group A, indirect fundal ophthalmoscopy, retinometer, eyebal axial length measurement were performed; in group B, F-ERG, F-VEP, eyebal axial length measurement were performed. According to the above results, postoperative visual acuity was predicted, which was compared with the best corrected visual acuity （BCVA） on 4 weeks after operation. Results The predicted postoperative visual acuity in 358 eyes was consistent with 4w postoperative BCVA, and there was no significant difference between group A and group B. The preoperative examination items were linearly correlated with the postoperative BCVA. Conclusion The preoperative examination can accu-rately predict postoperative visual acuity in cataract patients.
