【摘要】：目的對比AL-scan和A超測量眼球生物參數(shù)及人工晶狀體度數(shù)的差異,評價AL-scan的臨床應用價值。方法臨床病例檢測方法對照研究。應用AL-scan和A超對擬行白內障手術的患者75例(110只眼)進行眼軸長度(axial length,AL)、前房深度(anterior chamber depth,ACD)及角膜平均曲率(keratometry,K)的測量,根據(jù)AL分為三組,A組:22 mm≤AL24.5 mm 46例(66只眼),B組:24.5 mm≤AL26 mm 14例(21只眼),C組:AL≥26mm 15例(23只眼),應用SRK-T公式計算人工晶狀體(IOL)度數(shù),術后隨訪3月,計算平均絕對誤差(The mean absolute error,MAE)。結果A超與AL-scan測量AL、ACD在A組及C組中差異有統(tǒng)計學意義(P0.05),在B組無統(tǒng)計學意義(P0.05);測量K值在三組中無統(tǒng)計學意義(P0.05)。AL-scan在三組中測算MAE分別為(0.32±0.22)、(0.48±0.55)、(0.56±0.46)D,A超分別為(0.34±0.23)、(0.15±0.09)、(0.50±0.38)D,二者之間差異無統(tǒng)計學意義(P0.05),測量值之間均具有良好相關性。結論在三組中AL-scan測量所得AL、ACD值均比A超測量值大,在測量IOL度數(shù)方面與A超無差別,可應用于術前IOL的測算。
