目的：探讨超声乳化手术在白内障合并高度近视患者中的临床效果及疗效影响因素。

方法：回顾性分析2016-01/2019-01在我院住院的白内障合并高度近视患者90例109眼，所有患者均拟行白内障超声乳化联合人工晶状体植入术治疗，术后对患者进行6mo随访，根据最佳矫正视力评价手术疗效并进行分组：视力低下组(最佳矫正视力<0.3)和视力正常组(最佳矫正视力≥0.3)。建立Logistic回归分析模型，分析影响术后疗效的因素。

结果：视力低下组22例27眼，视力正常组68例82眼。随访期间，发生晶状体后囊膜混浊6眼，均为轻度混浊，激光治疗后改善，未见其他并发症的发生。单因素分析发现，眼轴长度、角膜散光度、Emery分级、眼底病变分级是影响手术疗效的影响因素(P<0.05)。Logistic回归分析结果显示，眼轴长度(OR=2.121)、角膜散光度(OR=1.698)、Emery分级(OR=1.901)和眼底病变分级(OR=1.964)是影响术后疗效的独立因素(P<0.05)。

结论：眼轴长度、角膜散光度、Emery分级和眼底病变分级是影响白内障超声乳化手术治疗白内障合并高度近视疗效的独立因素，但是影响患者预后因素较多，应根据影响因素制定有效的措施进行干预，提高患者手术预后。

METHODS:A retrospective analysis of 109 eyes of 90 patients with cataract combined with high myopia was performed on January 2016. According to the best corrected visual acuity, the curative effect was evaluated and divided into two groups: low vision group(best corrected visual acuity <0.3)and normal vision group(best corrected visual acuity ≥0.3). A Logistic regression analysis model was established to analyze the factors affecting the postoperative efficacy.

RESULTS:There were 22 cases(27 eyes)in the low vision group and 68 cases(82 eyes)in the normal vision group. During the follow-up period, 6 eyes of the posterior lens capsule became cloudy, all of which were mildly cloudy and improved after laser treatment. No complications such as secondary glaucoma, corneal decompensation, retinal detachment, and intraocular lens displacement were observed. Univariate analysis found that the axial length, corneal astigmatism, Emery classification, fundus lesion classification were the influential factors affecting the efficacy of the operation(P<0.05). Logistic regression analysis results showed that the axial length(OR=2.121), corneal astigmatism(OR=1.698), Emery classification(OR=1.901), and fundus lesion classification(OR=1.964)were independent factors affecting the postoperative efficacy(P<0.05).

CONCLUSION: Axial length, corneal astigmatism, Emery classification, and fundus lesion classification can affect cataract phacoemulsification surgery for cataract combined with high myopia, but patients have more influential factors for prognosis, and effective measures should be formulated according to influencing factors Intervention to improve the prognosis of patients.
