摘? 要:探討國產干涉條紋視力計對預測白內障術后視力的準確性及其影響因素。方法:收集105例(105眼)白內障患者,年齡為69.89±10.04歲(30~92歲),術前分別用德國Heine視網膜視力計和國產干涉條紋視力計檢測患者的術后預測視力,與術后1月最佳矯正視力比較,進行統計學分析。國產干涉條紋視力計和德國Heine視網膜視力計測量的預測視力分別為0.13±0.04和0.17±0.11,術后1月的最佳矯正視力為0.07±0.03,三者之間兩兩比較,有顯著性差異(P<0.05),國產干涉條紋視力計與術后最佳矯正視力之間的差異較小。國產干涉條紋視力計預測視力符合率為66.67%(兩者之間相差≤2行)。晶狀體重度混濁和合并眼部疾病如青光眼、黃斑前膜、糖尿病性眼底病變等是其影響因素。國產干涉條紋視力計能有效預測白內障術后視力,但在重度白內障和合并眼底其他疾病的患者應結合相關臨床檢查做綜合性評估。
關鍵詞:干涉條紋視力;白內障術后;最佳矯正視力;視網膜視力

Abstract:? To evaluate the accuracy of domestic interferometer on predicting postoperative visual acuity of cataract patients and its influencing factors. 105 patients (105 eyes) with cataract, aged 69.89 ± 10.04 years (range, 30-92 years), were examined by domestic interferometer and Heine retinometer, and compared with the best corrected visual acuity (BCVA) one month after surgery. Results: The predicted visual acuities were 0.13±0.04 and 0.17±0.11, respectively, and the best corrected visual acuities were 0.07±0.03 one month after operation. There was significant difference among the three groups (P < 0.05). The coincidence rate of domestic interferometer was 66.67% (the difference of tested visual acuity between them was less than 2 lines). Severe lens opacity and associated eye diseases such as glaucoma, macular pucker and diabetic retinopathy are the influencing factors. The domestic interferometer can effectively predict the postoperative visual acuity of cataract patients, but the patients with severe cataract or complicated with other ocular fundus diseases should be evaluated comprehensively in combination with related clinical examinations.
Key Words:? interferance visual acuity; postoperative of cataract; best corrected visual acuity; potential retinal visual acuity

白內障是全世界最主要的致盲性眼病,其患病率和發病率都處于較高的水平[1]。流行病學研究顯示,白內障是我國雙眼視力低下和盲的主要原因,占39%~64.6%[2-5]。隨著科技水平的提升,人工晶狀體的設計和功能日趨完善,白內障手術不再僅僅是復明手術,屈光性白內障手術的概念已深入人心。患者對術后的期望和要求也逐漸提高。因此術前詳細的眼部檢查以及預估術后視力的準確性顯得尤為重要。……
