AIM: To explore the risk factors of early low vision after phacoemulsification and intraocular lens implantion in the elderly patients with cataract. METHODS: A total of 278 cataract patients 310 eyes who underwent phacoemulsification and intraocular lens implantion were retrospectively studied. The susceptible preoperative risk factors to early low vision before the surgery, during the surgery process and ocular situation after the surgery were evaluated. The risk factors were analyzed by statistical multivariables analysis to investigate the factors which affect the early low vision. RESULTS: By univariate logistic regression analysis, it was indicated that nine factors were correlated with early low vision after surgery (P<0.05). By multi-variables logistic regression analysis, six factors were related to early low vision after surgery, including age(OR=1.637, 95% CI:1. 168-2. 293), preoperative corrected visual acuity (OR=1.745, 95% CI:1.169-2. 605), glaucoma (OR=3.645, 7 95% CI:1.537-8.645), ocular fundus abnormalities (OR=5.158, 95% CI:2.787-9. 546), time of phacoemulsification (OR=4.065, 95% CI:2.264-7.298) and corneal edema after surgery (OR=1.045, 95% CI:1.021-1.069). CONCLUSION: Older, preoperative low corrected visual acuity, glaucoma, ocular fundus abnormalities, longtime of phacoemulsification and corneal edema after surgery are risk factors affecting the early low vision after surgery. Ocular fundus abnormalities and long time of phacoemulsification are important risk factors.LA: Chinese
