目的 观察二点分辨力对预测白内障术后视力的作用。方法 对67例(69眼)白内障患者术前查二点分辨力,术后第5天查视力并进行对比。结果 术前二点分辨力越小,术后视力越好;术前二点分辨力越大,术后视力越差。结论 二点分辨力能比较有效地预测白内障术后视力。
Objective To observe the effect of two-point discrimination on predicting visual acuity after cataract surgery. Methods Sixty-seven patients (69 eyes) with cataract were examined with two-point resolving power and visual acuity was compared on the fifth day after operation. Results The smaller the preoperative resolution of the second point, the better postoperative visual acuity; the larger the preoperative resolution of the second point, the worse the postoperative visual acuity. Conclusion Two-point discrimination can be more effective in predicting the visual acuity after cataract surgery.
