醫(yī)學(xué)課件：球性硬鏡的驗(yàn)配方法和驗(yàn)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?？紤]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(shè)計，3階透鏡度數(shù)符合SAM FAP。Steep Add Minus陡加負(fù)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(shè)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(yīng)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

4、ens Movement: On blink，Vertical movement pattern Lens pushed down by lid down To or just past limb us Lens begins To move up under closed llls the Lens rotates such that the temporal edge moves down and the nasal edge moves up，dynamic stability Lens behavior between blinks normal lenens 熒光素染色，Wratten黃
