醫(yī)學課件：球性硬鏡的驗配方法和驗配原理

1、Fitting RGP lenses，school of optometry ophthalmology，Wenzhou medical college，fitting flow，baseline data，refractionre、corneal diameter k-reading rx、RGP lens : selection、brand or series、remember 3360 each series has their own fitting phittingHVID，中，12.0毫米=9.5直徑，HVID，大，兩步基本圓弧選擇，角膜散光為0.00 D 1.25 D 8.5直徑

2、0.25陡，K 9.0直徑為 K 9.5直徑0.25平于K。考慮到角膜散光1.50 D 2.50 D 8.5直徑0.75 K 9.0直徑0.50 K 9.5直徑0.25陡，K，2.50 D角膜散光-特殊環(huán)面設計，3階透鏡度數(shù)符合SAM FAP。Steep Add Minus陡加負鏡像Flat Add Plus平坦加正鏡像，示例，step # 2 k 讀數(shù)=43.00 180/44.75 90平坦 k=43.00角膜散光=1.75 D 第三階段平坦“K”=43.00基本弧=43.50佩戴者處方=-3.00 -1.75 X 180透鏡角度第二階段“K”讀數(shù)=42.25 180/43.00 90平坦

3、“K”=42.25角膜散光也就是說，鏡片與角膜最平坦的子午線接觸最多。42.00，46.00，RGP RGP鏡頭設計原則，熒光評估的內(nèi)容，位置活動圖(瞳孔位置)，靜態(tài)評估中速環(huán)境適應周圍環(huán)境，Lens Position，Vertical centered superior inferior the lens falls p seudo-lid attachment 3360 lens stays up even when lid is pulled away 3360 flat lens or wtr cornea need upper lid to cover top portities，L
