【摘要】：目的：觀察準(zhǔn)分子激光原位角膜磨鑲術(shù)（laser in situ keratomileusis, LASIK）矯治成人近視性屈參差術(shù)前及術(shù)后融合范圍和立體視變化，從視覺功能的角度上去評(píng)價(jià)LASIK手術(shù)的療效，為L(zhǎng)ASIK術(shù)后視覺質(zhì)量預(yù)測(cè)提供一定臨床依據(jù)。 方法：選取的對(duì)象是2013-1/2013-4期間在我院進(jìn)行LASIK手術(shù)治療的近視成人患者60例（120眼），按雙眼等效球鏡差≥2.0D分為屈光參差組與非屈光參差組各30例（60眼），隨診6個(gè)月，分別于術(shù)前，術(shù)后10天,術(shù)后1個(gè)月,術(shù)后3個(gè)月,術(shù)后6個(gè)月檢查視力、融合范圍、遠(yuǎn)和近立體視，比較兩組差異。 結(jié)果：60例患者經(jīng)LASIK術(shù)后裸眼視力均達(dá)到0.8以上，屈光參差組的雙眼屈光參差程度明顯減小。 立體視：非屈光參差組術(shù)后1個(gè)月較術(shù)前顯著改善（χ2=10.976，P=0.027），，其后漸趨平穩(wěn)；屈光參差組遠(yuǎn)、近立體視均有較明顯改善，近立體視術(shù)后1個(gè)月較術(shù)前比較有統(tǒng)計(jì)學(xué)意義（χ2=8.298，P=0.016），遠(yuǎn)立體視術(shù)后1個(gè)月較術(shù)前差異有統(tǒng)計(jì)學(xué)意義（χ2=7.084，P=0.029）。 融合范圍：隨時(shí)間推移先減低后升高（P=0.003），兩組術(shù)后3個(gè)月比較術(shù)前改善明顯（P0.05），另外，術(shù)后3個(gè)月時(shí)屈光參差組比較非屈光參差組差異有統(tǒng)計(jì)學(xué)意義（t=2.201,P=0.032）。 結(jié)論：由各種原因?qū)е碌慕晫⒅率闺p眼視覺功能有著不同程度的損害，如立體視覺和融合范圍。LASIK手術(shù)后雙眼恢復(fù)正視，立體視覺和融合范圍逐漸恢復(fù)正常范圍。對(duì)于屈光參差組，LASIK術(shù)消除雙眼視像不等，使得原本模糊的視網(wǎng)膜成像變得清晰，促進(jìn)雙眼單視功能的恢復(fù)，從而立體視覺和融合范圍得到改善。
[Abstract]:Objective: to observe the range of fusion and stereopsis before and after laser in situ keratomileusis (LASIK) for correction of myopia anisometropia in adults, and to evaluate the effect of LASIK operation from the angle of visual function. To provide a certain clinical basis for the prediction of visual quality after LASIK. Methods: sixty adult myopic patients who underwent LASIK operation in our hospital during 2013-1 / 2013-4 were divided into anisometropia group (n = 30) and non-anisometropia group (n = 30). Visual acuity, fusion range, distant and proximal stereopsis were examined 10 days, 1 month, 3 months and 6 months after operation. Results the naked visual acuity of 60 patients with LASIK was better than 0. 8, and the degree of anisometropia was decreased in the anisometropia group. Stereopsis: in the anisometropia group, there was a significant improvement at 1 month after operation (蠂 ~ 2 / 10.976 / P 0.027) and then became more stable, while in the anisometropia group, there was a significant improvement in the distance and near stereopsis, there was a significant improvement in the anisometropia group (P < 0.05). One month after operation, there was a significant difference between the two groups (蠂 ~ (2) 8.298P ~ (0.016) and one month after distant stereopsis (蠂 ~ (2) 7.084) (蠂 ~ (2) 7.084 (P ~ (0.029). The range of fusion: decrease first and then increase P0. 003 with the passage of time. The improvement of P0. 05 was significant in the two groups 3 months after operation. In addition, there was a significant difference between the anisometropia group and the non anisometropia group at 3 months after operation. Conclusion: myopia caused by various causes will result in different degrees of damage to binocular visual function, such as stereoscopic vision and fusion range. For anisometropia group, LASIK eliminates the disparity of binocular vision, makes the original blurred retinal imaging clear, promotes the recovery of binocular monocular function, and improves the range of stereo vision and fusion.
