Related factors influencing the curative effect for cataract patients with high myopia

Abstract

AIM:To analyze the influencing factors of the curative effect of cataract extraction in cataract patients with high myopia. METHODS: A total of 86 patients(118 eyes)with high myopia and undergoing cataract extraction were enrolled in the retrospective study. All patients completed follow-up in 6mo after surgery and the clinical data were complete. The best corrected visual acuity(BCVA)was recorded in 6mo after surgery. With 0.3 as the dividing line, the patients were divided into the low visual acuity group(the visual acuity RESULTS: Among all patients, there were 34 eyes(29%)with low visual acuity and 84 eyes(71%)with normal visual acuity. The axial length, corneal astigmatism, proportion of with macular lesions, proportion of with posterior sclerotic staphyloma, the hardness of the lens nucleus and degree of fundus lesions showed statistically significant differences between the low visual acuity group and the normal visual acuity group(POR:1.567, 95%CI: 1.129-2.224), macular lesions(OR:8.054, 95%CI:1.741-37.541), the hardness of the lens nucleus(OR:3.642, 95%CI:2.512-18.787)and the degree of fundus lesions(OR:7.964, 95%CI:1.254-28.415)were associated with the curative effect in patients with cataract and high myopia(PCONCLUSION:The axial length, macular lesions, hardness of the lens nucleus and degree of fundus lesions are the independent risk factors for visual acuity recovery in cataract patients with high myopia after surgery. To improve the visual recovery after surgery, the risk factors must be controlled actively and attention should be paid to fine surgery.
