【摘要】：目的：觀察波前像差引導(dǎo)的準(zhǔn)分子激光原位角膜磨鑲術(shù)(laser in situ keratomileusis, LASIK)術(shù)后客觀指標(biāo)及主觀視覺質(zhì)量問卷評估,并與常規(guī)LASIK做對比,分析波前像差引導(dǎo)的LASIK治療近視的療效。 方法：連續(xù)選取2009年7月至2010年2月在我院接受波前像差引導(dǎo)的LASIK的近視患者21例(40眼)作為波前組,以及同期接受常規(guī)LASIK的近視患者16例(31眼)作為對照組,術(shù)后隨訪1年,術(shù)前及術(shù)后隨訪時檢查視力、屈光度、高階像差,并于術(shù)后隨訪時填寫主觀視覺質(zhì)量問卷,對兩組結(jié)果分別進(jìn)行比較分析。 結(jié)果： 1.術(shù)后1月兩組裸眼視力(uncorrected visual acuity, UCVA)均≥1.0。術(shù)后1年所有患者UCVA均≥0.8,其中UCVA≥1.0者波前組97.5%,對照組96.8%,UCVA≥1.5者波前組35.0%,對照組16.1%；較術(shù)前最佳矯正視力(best corrected visual acuity, BCVA)提高者,波前組37.5%,對照組19.4%,波前組優(yōu)于對照組,但差異均無統(tǒng)計學(xué)意義(P0.05)； 2.術(shù)后兩組等效球鏡度差異無統(tǒng)計學(xué)意義(P0.05),隨時間變化兩組屈光度僅輕度回退；術(shù)后1年時波前組等效球鏡度在(+1.0D～-1.0D)和(+0.5D～-0.5D)范圍內(nèi)者所占比分別為75.0%和95.0%,與對照組(分別為77.4%和93.5%)比較差異無統(tǒng)計學(xué)意義(P0.05)； 3.術(shù)后兩組總高階像差、彗差、球差值均高于術(shù)前(P0.05),隨時間推移輕度下降。術(shù)前兩組的總高階像差、彗差、球差值差異無統(tǒng)計學(xué)意義(p0.05)：術(shù)后波前組總高階像差、彗差、球差低于對照組(P0.05)；波前組術(shù)后總高階像差、彗差、球差增加幅度小于對照組(P0.05)； 4.術(shù)后主觀視覺質(zhì)量問卷在視力評估方面,白天和傍晚視力兩組間差異無統(tǒng)計學(xué)意義(P0.05),夜晚和夜晚駕駛視力波前組優(yōu)于對照組(P0.05),隨時間延長各條件下視力評估變化不顯著(P0.05)；視覺癥狀方面,波前組眩光的出現(xiàn)少于對照組(P0.05),光暈、重影、夜晚駕駛困難各項兩組間差異無統(tǒng)計學(xué)意義(P0.05)；兩組光暈隨時間延長均明顯減輕(P0.05)。 結(jié)論：波前像差引導(dǎo)的LASIK與常規(guī)LASIK術(shù)后均獲得良好的裸眼視力；屈光度均基本穩(wěn)定,可預(yù)測性良好；總高階像差、彗差、球差均較術(shù)前增加,隨時間推移僅輕度下降；與常規(guī)LASIK相比,波前像差引導(dǎo)的LASIK可以減少術(shù)后高階像差的增幅,減少術(shù)后眩光的發(fā)生,從而改善夜間視覺質(zhì)量。
[Abstract]:Aim: to observe the objective index and subjective visual quality of wave front aberration guided excimer laser in situ keratomileusis (laser in situ keratomileusis, LASIK) and compare it with conventional LASIK to analyze the efficacy of wavefront aberration guided LASIK in the treatment of myopia. Methods: from July 2009 to February 2010, 21 myopia patients (40 eyes) with LASIK guided by wavefront aberration were selected as wave front group, and 16 myopia patients (31 eyes) who received routine LASIK were selected as control group. The visual acuity, diopter and high-order aberration were examined before and after the follow-up. The subjective visual quality questionnaire was filled out in the follow-up. The results of the two groups were compared and analyzed. Results: 1. One month after operation, the naked visual acuity (uncorrected visual acuity, UCVA) of both groups was 鈮，
