以直徑8.5 mm的硬性隱形眼鏡作為臨床裝配的試戴鏡片,共收集127人,247眼,其第一次定期檢查之結果主訴良好者佔74.5%,其餘有症狀者25.5%,以異物感最多、流淚、視力模糊等等次之。 不良之原因中以處方不正確為最多、鏡片不良、鏡片污穢、使用不當等等次之。經過處理後,能良好使用直徑8.5 mm者佔85.5%,其餘有6眼需將直徑放大,26眼需將直徑放小,4眼需改用軟性鏡片。

The rest of 25.5% which had trouble was treated by new lens replacement, lens modification, or lens handling technique retraining, etc. After management we found that 85.5% can use size 8.5 mm H. C.
