摘要
目的通过国产干涉条纹视力计与Heine干涉条纹视力计在预测白内障患者术后视力中的应用对比,探讨国产干涉条纹视力计预测白内障患者术后视力的准确性、实用性、可行性。方法将71例(92眼)白内障患者平均分成2组,术后的视功能情况分别用国产干涉条纹视力计与Heine干涉条纹视力计2种方法进行预测,结果与患眼术后最佳矫正视力进行相关性分析对比。结果国产干涉条纹视力计预测的准确率为81.0%(预测视力与术后视力相差2行以内者认为准确),平均预测视力(4.695)与平均术后最佳矫正视力(4.771)比相差不到1行。Heine干涉条纹视力计预测的准确率为43·9%,平均预测视力(4.481)与平均术后最佳矫正视力(4.771)比相差约3行。结论比起Heine干涉条纹视力计,国产干涉条纹视力计检查更能合理的反映视觉功能,对白内障术后视力具有较好的预测性。
Objective To assess the veracity, practicability, feasibility of domestic interferometer through comparing it with the Heine interferometer. seventy-one cataract patients （ninety-two eyes） were divided into two groups. The potential visual acuities （PVA） were assessed by domestic interferometer and Heine interferometer. The results were compared with their best corrected visual acuity（BCVA）.Results The accuracy of the domestic interferometer in predicting visual acuity posttreatment was 81.0% （ difference between PVR and BCVA in two lines were regarded as accuracy）, The predicted visual acuity（4. 695） of the domestic interferorneter was inaccurate by an average of less than one line lower comparing with BCVA （ 4. 771 ）. The accuracy of the Heine interferometer in predicting visual acuity posttreatmeut was 43.9% . The predicted visual acuity（4. 481）was inaccurate by an average of almost 3 lines lower comparing with BCVA （4.771）. Conclusion Domestic interferometer can predict visual acuity more reasonably than Heine interferometer. It is a useful instruction to predict visual acuity after cataract surgery.
