【摘要】：一、不同屈光度數(shù)近視飛秒LASIK術(shù)后早期視覺(jué)質(zhì)量的評(píng)估目的:分析不同度數(shù)近視飛秒LASIK手術(shù)前后視覺(jué)質(zhì)量。方法:選擇接受飛秒LASIK手術(shù)近視患者118人分為超高度近視、高度近視、中度近視及低度近視組。分別于術(shù)前、術(shù)后1d、lw、1m、3m、6m檢查UCVA、BCVA、SE、波前像差、OQAS視覺(jué)質(zhì)量參數(shù),并對(duì)數(shù)據(jù)進(jìn)行分析。結(jié)果:1.四組術(shù)后視力及屈光改變均是安全和有效的。2.四組散射指數(shù)OSI在術(shù)后早期均增高,近視度數(shù)越高OSI升高越明顯。3.術(shù)后6m中低度近視組MTF_(cutoff)、OV100%、OV20%較術(shù)前升高(P0.05),SR與術(shù)前比差異無(wú)統(tǒng)計(jì)學(xué)意義。高度近視組MTF_(cutoff)較術(shù)前增高(P0.05),SR、OV100%、OV20%、OV9%無(wú)明顯差異(P0.05),超高度近視組除MTF不變外,其他參數(shù)均較術(shù)前降低(P0.05)。4.術(shù)后6m OSI、MTF_(cutoff)、SR、OV100%、OV20%、OV9%與SE及切削深度相關(guān)(P0.05)。5.四組術(shù)后HOAs、球差、和彗差均較術(shù)前增加(P0.05),術(shù)后6m HOAs、球差在高度和超高度近視組較中低度近視組高(P0.05),彗差、三葉草像差在各組差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。6.術(shù)后6m HOAs、球差與術(shù)后視力、OSI、MTF及SR相關(guān),彗差與術(shù)前SE及術(shù)前散光度數(shù)相關(guān)。結(jié)論:1.飛秒LASIK矯正近視是安全有效的。2.術(shù)后6月視覺(jué)質(zhì)量參數(shù)中低度近視好于高度及超高度近視。散射指數(shù)OSI能較早反應(yīng)屈光手術(shù)后視覺(jué)質(zhì)量改變。3.OQAS參數(shù)與波前像差在評(píng)估屈光手術(shù)后視覺(jué)質(zhì)量時(shí)存在相關(guān)性。二、ICL植入術(shù)和飛秒LASIK矯治高度及超高度近視視覺(jué)質(zhì)量分析目的:評(píng)估高度及超高度近視ICL植入術(shù)和飛秒LASIK手術(shù)前后的視覺(jué)質(zhì)量。方法:選擇行ICL植入術(shù)的高度近視14人(14眼)及超高度近視20人(20眼),行飛秒LASIK術(shù)的高度近視15人(15眼)及超高度近視人19人(19眼)于術(shù)前,術(shù)后1w、1m、3m、6m檢查UCVA、BCVA、SE、波前像差、OQAS視覺(jué)質(zhì)量參數(shù),并對(duì)所得數(shù)據(jù)進(jìn)行分析。結(jié)果:1.術(shù)后6m四組UCVA、BCVA均較術(shù)前明顯提高,ICL組術(shù)后BCVA均好過(guò)飛秒LASIK組(P0.05)。四組術(shù)后等效球鏡度數(shù)明顯降低(P0.05)。2.ICL植入兩組術(shù)后6m MTF_(cutoff)、SR、OV100%、OV20%、OV9%較術(shù)前提高(P0.05),OSI無(wú)明顯改變(P0.05),LASIK組術(shù)后OSI均較術(shù)前增高(P0.05),高度近視術(shù)后MTF_(cutoff)較術(shù)前增高(P0.05),SR、OV100%、OV20%、OV9%無(wú)變化。超高度近視除MTF_(cutoff)外其他參數(shù)較術(shù)前降低(P0.05)。3.高度近視術(shù)后6m ICL組MTF_(cutoff)與LASIK組差異不具有統(tǒng)計(jì)學(xué)意義(P0.05),其他OQAS參數(shù)較LASIK組好(P0.05)。超高度近視ICL組術(shù)后OQAS參數(shù)均較LASIK組好(P0.05)。4.ICL兩組術(shù)后MTF_(cutoff)、SR、OV9%差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。高度近視組OSI較超高度近視組低,OV100%、OV20%較高(P0.05)。LASIK術(shù)后6m高度近視組OQAS參數(shù)均較超高度近視組好(P0.05)。5.高度、超高度近視ICL術(shù)后HOAs、球差、彗差與術(shù)前比較差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。而LASIK組較術(shù)前提高,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。兩組三葉草像差差異無(wú)統(tǒng)計(jì)學(xué)意義。6.ICL組術(shù)后6m HOAs、球差均較飛秒LASIK低(P0.05)。7.高度近視及超高度近視ICL術(shù)后波前像差結(jié)果差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。而LASIK術(shù)后總高階像差、球差、彗差間差異有統(tǒng)計(jì)學(xué)意義(P0.05)。三葉草像差差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論1.四組術(shù)后均有良好的屈光效果和視覺(jué)質(zhì)量。2.高度及超高度近視ICL植入術(shù)后6月客觀視覺(jué)質(zhì)量檢查結(jié)果均優(yōu)于飛秒LASIK。3.高度近視及超高度近視在ICL植入術(shù)后視覺(jué)質(zhì)量?jī)HOSI、OV100%及OV20%有差異,飛秒LASIK術(shù)后6月高度近視組波前像差參數(shù)除三葉草像差外其他各參數(shù)均優(yōu)于超高度近視組(P0.05)。三、傳統(tǒng)ICL及帶孔型ICL矯正高度近視視覺(jué)質(zhì)量的研究目的:對(duì)帶孔型及傳統(tǒng)型ICL手術(shù)的視覺(jué)質(zhì)量進(jìn)行對(duì)比研究。方法:選擇高度近視行傳統(tǒng)型ICL植入術(shù)的患者11人(21眼)及行帶孔型ICL植入術(shù)的12人(20眼),于手術(shù)前、術(shù)后6m檢查UCVA、BCVA、SE、波前像差、OQAS視覺(jué)質(zhì)量參數(shù),并對(duì)所得數(shù)據(jù)進(jìn)行分析。結(jié)果:1.兩組術(shù)后UCVA和BCVA均較術(shù)前增高(P0.05),而術(shù)后UCVA及BCVA兩組間比較差異無(wú)統(tǒng)計(jì)學(xué)意義(P0.05)。2.兩組術(shù)后6m SE、散光度數(shù)較術(shù)前降低(P0.05),術(shù)后6m兩組散光度數(shù)飛秒LASIK較ICL植入組少(P0.05)。3.兩組術(shù)后6m視覺(jué)質(zhì)量均較術(shù)前提高(P0.05)。術(shù)后6m二者比較OQAS視覺(jué)質(zhì)量參數(shù)差異不具有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論:1.兩組矯正高度近視是安全有效的。2.兩組術(shù)后6月OQAS視覺(jué)質(zhì)量評(píng)估均較術(shù)前增高,術(shù)后6月兩者間視覺(jué)質(zhì)量差異無(wú)統(tǒng)計(jì)學(xué)意義。
[Abstract]:A, early assessment of visual quality to different degrees of refraction myopia after LASIK femtosecond: analysis of different degrees of myopia before and after femtosecond LASIK visual quality. Methods: 118 patients with myopia underwent femtosecond LASIK surgery were divided into high myopia, high myopia, moderate myopia and low myopia group respectively. Preoperative, postoperative 1D. LW, 1M, 3M, 6m, BCVA, SE, UCVA, wavefront aberration, OQAS visual quality parameters, and analyze the data. Results: 1. of four groups of postoperative visual acuity and refractive changes are safe and effective in four groups of.2. scattering index OSI in the early postoperative period were increased, the higher the degree of myopia OSI the more obvious after.3. 6m in low myopia group MTF_ (cutoff), OV100%, OV20% higher than that before operation (P0.05), and SR before surgery was not statistically significant. High myopia group (cutoff MTF_) higher than preoperative (P0.05), SR, OV100%, OV20%, OV9% showed no significant difference (P0.05) super high, nearly 瑙嗙粍闄TF涓嶅彉澶，
