【摘要】：目的观察分析准分子激光原位角膜磨镶术(laser in situ keratomileusis, LASIK)前后近视人群主导眼分布特点及主导眼转变对术后视觉满意度的影响。方法依照随机对照表选取行LASIK术的190例近视患者(380只眼),并按双眼屈光参差度及主导眼眼别分为三组,①无屈光参差组:即组A,两眼等效球镜度差异≤1.75 D的受试者归入该组,共154例。②屈光参差组:两眼等效球镜差异1.75D,共36例。包括组B,主导眼为近视度数较高眼,共19例;组C,主导眼为近视度数较低眼,共17例。所有患者均于术前和术后一月分别检查裸眼视力、屈光度、卡洞法确定主导眼等指标,术后1mo接受远近视觉满意度问卷调查。统计结果并加以比较分析。结果 LASIK术前右眼为主导眼125例(65.8%),左眼65例(34.2%);术后92例以右眼为主导眼(48.4%),左眼98例(51.6%)。59例(31.1%)患者在术后发生主导眼转变。组B,屈光参差(1.75D)患者中主导眼为较高近视度眼,主导眼转变率(47%)高于组A、C(29%)。术前主导眼眼别与屈光参差、最佳裸眼视力眼别一致性差(p0.05),术后主导眼相对非主导眼近视屈光度低。对比手术前后主导眼发生转变和未发生转变的患者,其术后远近视觉满意度无显著差别。结论准分子激光原位角膜磨镶术作为一个刺激因素,在矫正近视屈光不正状态的同时,存在主导眼的改变,即关键期后,眼优势具有可塑性,尤其在有屈光参差且主导眼为近视度数较高眼的患者中发生率更高。但主导眼改变与否其术后视觉满意度无显著差别。术后主导眼眼别与屈光度相关,主导眼较非主导眼近视度数低。
[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 卤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.
