【摘要】:目的探討Acrysof IQ Restor Toric人工晶狀體植入術(shù)前后患眼散光、像差及調(diào)制傳遞函數(shù)(modulation transfer function,MTF)值變化,評價(jià)此種晶狀體對術(shù)眼視覺質(zhì)量的影響。方法觀察在我院行白內(nèi)障超聲乳化摘出聯(lián)合IQ Restor Toric IOL植入的白內(nèi)障合并角膜散光≥1.0 D的患者8例(10眼),分別于術(shù)前、術(shù)后1個(gè)月、3個(gè)月測量裸眼遠(yuǎn)中近視力、最佳矯正遠(yuǎn)近視力、等效球鏡、殘余散光及IOL軸位、總低階像差和高階像差、MTF值并問卷調(diào)查視覺滿意度等。結(jié)果術(shù)后3個(gè)月,裸眼遠(yuǎn)視力為0.85±0.30,最佳矯正遠(yuǎn)視力為0.92±0.27,裸眼近視力為0.73±0.22,最佳矯正近視力為0.76±0.20,裸眼中視力為0.62±0.18;等效球鏡度數(shù)≤±0.5 D者9眼(90%)。術(shù)后3個(gè)月全眼總散光由術(shù)前的(1.50±0.41)D降至(0.28±0.43)D(t=6.124,P=0.000),與術(shù)前預(yù)計(jì)殘留散光(0.13±0.09)D相比差異無統(tǒng)計(jì)學(xué)意義(P0.05)。術(shù)后3個(gè)月,IOL軸位偏離(3.20±1.55)°。所有瞳孔直徑下,總像差、低階像差、高階像差、球差與術(shù)前相比均有顯著下降(均為P0.05),術(shù)后3 mm瞳孔直徑下的總像差、低階像差和高階像差(P=0.034、0.044、0.005)以及5 mm瞳孔直徑下的總像差、低階像差、散光像差(P=0.048、0.033、0.046)隨時(shí)間推移仍有顯著降低,余像差隨時(shí)間變化雖有下降,但差異均無統(tǒng)計(jì)學(xué)意義(均為P0.05)。不同瞳孔直徑下,MTF值在各個(gè)空間頻率下與術(shù)前相比均有顯著提高(均為P0.05)。結(jié)論 Acrysof IQ Restor Toric多焦點(diǎn)散光型人工晶狀體能為白內(nèi)障患者提供良好的全程視力和有效的散光矯正,減少了全眼高階像差和球差,從而提高了患者的術(shù)后視覺質(zhì)量。
