【摘要】：目的觀察LASIK術(shù)后遠(yuǎn)期的角膜高階像差變化及對(duì)日常生活中視覺功能的影響。方法對(duì)67例(134眼)接受非球面切削程序引導(dǎo)的LASIK的患者隨訪4 a。收集術(shù)前及術(shù)后6個(gè)月、4 a患者的視力、角膜地形圖、球差和彗差資料,并由同一名醫(yī)師完成患者術(shù)后視覺功能的評(píng)價(jià)。結(jié)果術(shù)后4 a隨訪中無一例患者最佳矯正視力較術(shù)前視力下降;術(shù)后6個(gè)月和4 a的有效性指數(shù)、安全性指數(shù)分別達(dá)1.08±0.16、1.11±0.17和1.12±0.16、1.13±0.14。不管是術(shù)后6個(gè)月還是4 a的角膜球差和彗差均較術(shù)前顯著增加,但術(shù)后兩個(gè)時(shí)間點(diǎn)間角膜像差的差異均無統(tǒng)計(jì)學(xué)意義(均為P0.05)。大部分患者對(duì)日常生活中的各項(xiàng)視覺功能感到滿意或很滿意(94.3%、92.4%)。術(shù)后4 a隨訪中有7.4%患者訴夜間開車?yán)щy。進(jìn)一步分析視覺功能評(píng)分與角膜像差的關(guān)系,發(fā)現(xiàn)夜間開車?yán)щy與角膜球差呈負(fù)相關(guān)(術(shù)后6個(gè)月:r=-0.66,P=0.040;術(shù)后4 a:r=-0.69,P=0.039),而且并沒有隨時(shí)間延長(zhǎng)而顯著改善。結(jié)論近視患者LASIK術(shù)后有遠(yuǎn)期穩(wěn)定的角膜像差和日常生活中的視覺功能感受。
[Abstract]:Objective to observe the changes of corneal higher-order aberrations and their effects on visual function in daily life after LASIK. Methods 67 cases (134eyes) of LASIK undergoing aspheric ablation procedure were followed up for 4 years. Six patients were collected before and after operation. Visual acuity of patients with 4 years. Corneal topography, spherical aberration and coma data, and the evaluation of postoperative visual function was performed by the same physician. Results none of the patients had the best corrected visual acuity (BCVA) as compared with the preoperative visual acuity after 4 years follow-up. The efficacy index and safety index of 6 months and 4 years after operation were 1.08 鹵0.16 鹵1.11 鹵0.17 and 1.12 鹵0.16 鹵1.13 鹵0.14 respectively. However, there was no significant difference in corneal aberration between the two time points after operation (P 0.05). Most of the patients were satisfied or satisfied with the visual functions in their daily life. 7.4% patients complained of driving at night during the follow-up 4 years after operation. Difficulties. Further analysis of the relationship between visual function score and corneal aberration, It was found that there was a negative correlation between nocturnal drivage difficulty and corneal spherical aberration (6 months after operation: 1: r-0.66, P0. 040; 4 a: r-0. 69, P0. 039, and not significantly improved with time. Conclusion myopia patients have long-term stable corneal aberration and visual function perception in daily life after LASIK. [WT5 "HZ] [WT5" BZ] [WT5 "BZ] [WT5" BZ] [WT5BZ]
