Factors Affecting Early Postoperative Visual Acuity in Cataract Patients with High Myopia

Abstract

Purpose: To analyze the short-term results of cataract surgery in patients with high myopia and determine the risk factors responsible for early postoperative visual outcome. Methods: A total of 93 patients (115 eyes) with high myopia who underwent phacoemulsification and intraocular lens (IOL) implantation were enrolled in this retrospective study. Complete ophthalmologic examinations were performed preoperatively and postoperatively. According to the best-corrected visual acuity (BCVA) at one week after surgery, all patients were divided into Group A (postoperative BCVA ≥ 20/40) and Group B (postoperative BCVA < 20/40) for comparison and to identify the related factors of early postoperative vision. The difference between the two groups was analyzed with independent t-text. Logistic regression was utilized to analyze age, axial length (AL), maculopathy and other related factors for early postoperative BCVA. Results: Among the 115 eyes, group A were 66 eyes and group B were 49 eyes. In multivariate regression analysis, maculopathy (OR: 5.586, 95% CI: 1.704-18.311), posterior staphyloma (OR: 3.698, 95% CI: 1.002-13.652) and preoperative visual acuity (VA) (OR: 4.835, 95% CI: 1.96211.915) were associated with early postoperative BCVA in cataract with high myopia (all p < 0.05), while not associated with age, AL and other factors (all p > 0.05). Conclusion: Most of the eyes with high myopia achieved satisfactory improvement in postoperative BCVA. In the short-term study, the lower the preoperative VA, pre-existing maculopathy or posterior staphyloma are risk factors for early postoperative BCVA recovery in cataract patients with high myopia.
