Abstract:AIM: To analyze influencing factors of the curative effect of phacoemulsification(PHACO)combined with intraocular lens implantation in the treatment of high myopia with cataract.
METHODS: The clinical data of 80 cases patients(91 affected eyes)with cataract and high myopia who underwent phacoemulsification and intraocular lens implantation in the hospital from February 2016 to March 2019 were analyzed retrospectively. According to the best corrected visual acuity(BCVA)at 3mo after operation, the patients were divided into low vision group(BCVA<0.3)and normal group(BCVA≥0.3). The preoperative clinical data of the two groups were compared, and the factors affecting visual recovery were analyzed.
RESULTS: All patients completed surgery successfully, and there were statistically significant differences in BCVA before and after surgery(P<0.001). No serious complications such as corneal decompensation, secondary glaucoma and intraocular lens displacement were found. There were significant differences in age, myopia time, axial length, preoperative intraocular pressure, corneal astigmatism, anterior capsular opening area, central anterior chamber depth, grade of lens nucleus and incidence rates of diabetic retinopathy, posterior scleral staphyloma, macular degeneration and postoperative macular edema between the low vision group and the normal group(P<0.05). Multivariate Logistic regression analysis showed that axial length >30 mm, preoperative intraocular pressure ≥21mmHg, corneal astigmatism ≥1.30D, grade Ⅲ-Ⅳ lens nucleus, preoperative diabetic retinopathy and macular degeneration were the independent risk factors for postoperative visual recovery in patients with high myopia and cataract(P<0.05).
CONCLUSION: PHACO combined with intraocular lens implantation is markedly effective in the treatment of high myopia with cataract. However, the curative effect is affected by axial length, preoperative intraocular pressure, corneal astigmatism, grade of lens nucleus, preoperative diabetic retinopathy and macular degeneration, which deserves attention.
