【摘要】：目的 觀察分析準分子激光原位角膜磨鑲術(laser in situ keratomileusis, LASIK)前后近視人群主導眼分布特點及主導眼轉變對術后視覺滿意度的影響。 方法 依照隨機對照表選取行LASIK術的190例近視患者(380只眼),并按雙眼屈光參差度及主導眼眼別分為三組,①無屈光參差組:即組A,兩眼等效球鏡度差異≤1.75 D的受試者歸入該組,共154例。②屈光參差組:兩眼等效球鏡差異1.75D,共36例。包括組B,主導眼為近視度數(shù)較高眼,共19例;組C,主導眼為近視度數(shù)較低眼,共17例。所有患者均于術前和術后一月分別檢查裸眼視力、屈光度、卡洞法確定主導眼等指標,術后1mo接受遠近視覺滿意度問卷調(diào)查。統(tǒng)計結果并加以比較分析。 結果 LASIK術前右眼為主導眼125例(65.8%),左眼65例(34.2%);術后92例以右眼為主導眼(48.4%),左眼98例(51.6%)。59例(31.1%)患者在術后發(fā)生主導眼轉變。組B,屈光參差(1.75D)患者中主導眼為較高近視度眼,主導眼轉變率(47%)高于組A、C(29%)。術前主導眼眼別與屈光參差、最佳裸眼視力眼別一致性差(p0.05),術后主導眼相對非主導眼近視屈光度低。對比手術前后主導眼發(fā)生轉變和未發(fā)生轉變的患者,其術后遠近視覺滿意度無顯著差別。 結論 準分子激光原位角膜磨鑲術作為一個刺激因素,在矯正近視屈光不正狀態(tài)的同時,存在主導眼的改變,即關鍵期后,眼優(yōu)勢具有可塑性,尤其在有屈光參差且主導眼為近視度數(shù)較高眼的患者中發(fā)生率更高。但主導眼改變與否其術后視覺滿意度無顯著差別。術后主導眼眼別與屈光度相關,主導眼較非主導眼近視度數(shù)低。
[Abstract]:Purpose The distribution of dominant eyes in myopia before and after laser in situ keratomileusis (LASE) and the effect of leading eye change on postoperative visual satisfaction were observed and analyzed. Method According to the random control table, one hundred and eighty patients with myopia underwent LASIK operation were selected and divided into three groups according to the anisometropia degree and the dominant eye type: group A, the subjects whose equivalent spherical specular degree difference was less than 1.75D were included in this group, and the patients with anisometropia were divided into three groups according to the degree of anisometropia. A total of 154 cases of anisometropia group: two eyes equivalent spherical mirror difference 1.75 D, a total of 36 cases. There were 19 cases in group B with higher myopia and 17 cases in group C with lower degree of myopia. The visual acuity, diopter and hole-hole method were examined in all patients before and one month after operation. 1mo was investigated with visual satisfaction questionnaire. The statistical results are compared and analyzed. Result Before LASIK, the right eye was the dominant eye in 125 cases, the left eye in 65 cases was 34.2%, and the right eye was the dominant eye in 92 cases and the left eye in 98 cases (51.6 鹵59.59 cases). In group B, anisometropia 1.75 D), the dominant eye was high myopia, and the conversion rate of dominant eye was 47) higher than that in group A C29. Preoperative dominant eye and anisometropia, the best naked eye visual acuity difference (P 0.05), postoperative dominant eye relative to the non-dominant eye myopia diopter is low. There was no significant difference in the visual satisfaction between the patients with or without the change of the dominant eye before and after operation. Conclusion As a stimulating factor, excimer laser in situ keratomileusis (LASIK) can correct myopia ametropia, and at the same time, there are leading eye changes, that is, after the critical period, the ocular dominance has plasticity. Especially in patients with anisometropia and higher myopia in dominant eyes, the incidence was higher. But there was no significant difference in visual satisfaction after operation. The myopia degree of dominant eye was lower than that of non-dominant eye.
