AIM:To investigate the clinical effect and influencing factors of phacoemulsification in cataract patients with high myopia.

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.
