Abstract
Objective To explore the risk factors and prognosis of posterior capsule rupture in phacoemulsification of cataract. Methods A total of 2,409 cases (2,576 eyes) scheduled for cataract phacoemulsification in our hospital between January 2014 and October 2015 were included in the retrospective study. Among the patients 24 cases (26 eyes) of posterior capsular rupture patients were seleted as the observation group, and 120 patients (135 eyes) were selected from the remaining patients as control group, with a ratio of 1 to 5. If the selected patients had posterior capsule rupture, they were removed and other patients were selected. Clinical data such as age, gender, preoperative intraocular pressure (IOP), cataract type and grade, preoperative and postoperative vision, a history of glaucoma and concomitant diseases were compared between the two groups. The risk factors and prognosis of posterior capsular rupture were analyzed. Results The incidence of posterior capsular rupture in the male was higher than that in the female ( < 0.05). Preoperative visual acuity less than 20/200 was one of the risk factors of posterior capsular rupture ( < 0.05). The incidence of posterior capsular rupture was significantly increased in the patients of degree IV and above nuclear cataract, the difference was statistically significant ( < 0.05). In the observation group the average visual acuity was (2.3 ± 0.8) LogMAR before treatment and (1.1 ± 0.6) LogMAR after treatment, the difference was statistically significant ( < 0.05). In the control group, the average visual acuity was (1.7 ± 0.4)LogMAR before treatment and (0.8 ± 0.5) LogMAR after treatment, the difference was statistically significant ( <0.05). Age, preoperative IOP, glaucoma history or concomitant diseases had no obvious correlation with posterior capsule rupture ( >0.05). Conclusions Gender, preoperative visual acuity and cataract grading are associated with posterior capsular rupture in contact phacoemulsification. Analysis of these factors should be emphasized in the process of clinical diagnosis and treatment to avoid the rupture of posterior capsule after surgery and promote the recovery of visual acuity.关键词
