摘要

我們測試十四位（二十八眼）接受放射狀角膜切開術之病人之對比敏感度，測試時間由術後一至二十四月不等。我們所採取的手術為標準八刀切開方式。我們另外測試一群十一位（二十二眼）與開刀病人近視程度及年齡相當但未開刀之人之對比敏感度。這項研究的目的在以比較手術眼與未手術眼之對比敏感度差異，來評估放射狀角膜切開術對其所造成的影響。我們發現在手術後之前幾個月，對比敏感度有顯著降低，但在一年之後，已逐漸恢復到接近未開刀之對照組。然而，在本實驗中，炫光之有無並未對對比敏感度產生顯著的影響。

並列摘要

We tested contrast sensitivity in 14 patients (28 eyes), ranging froth 1 to 24 months after radial keratotomy. These patients underwent a standard eight-incision radial keratotomy procedure. We also tested 22 unoperated eyes in another group of 11 patients, whose spherical equivalent and age were similar to that of the operated group. The present study was to evaluate wheather radial keratotomy produces an alteration in contrast sensitivity by comparing this function in operated versus unoperated eyes. Impairment of contrast sensitivity was found in early months immediately after surgery, but the function recovered up to the level of unoperated eyes about one year after operation. However, the contrast sensitivity did not reveal significant difference under the condition the glare source existed.
