Abstract Objective To investigate the related influence factors of phacoemulsification (PE) combined with intraocular lens implantation (IOL) on the incidence of exudation in anterior chamber (AC). Methods The clinical data of 389 cataract patients (405 eyes) treated with PE combined with IOL implantation in Liuzhou Liutie Central Hospital from March 2015 to October 2017 were analyzed retrospectively. There were 23 cases (24 eyes) occuring exudation in AC as study group, and 366 cases (381 eyes) without exudation in AC as control group. Statistical analysis of the incidence of AC exudation after surgery were performed. Multivariate Logistic regression analysis was carried out. Results High myopia, glaucoma, preoperative intraocular pressure(IOP)＞21 mmHg(1 mmHg=0.133 kPa), preoperative vision＜1, posterior capsular rupture (PCR), in ultrasonic accumulated energy complex parameter (AECP)＞7.25(%×min), intraoperative pupil diameter＜3 mm, uveitis, lenticular nucleus classification≥Ⅳ levels, all the 9 indices had significant difference between the two groups (P ＜ 0.05), and they were risk factors of exudation in AC. Among the 9 factors, 7 factors, glaucoma, uveitis, high myopia, PCR, ultrasonic in AECP＞7.25(%×min), preoperative IOP＞21 mmHg, lenticular nucleus classification≥Ⅳ levels were independent risk factors (P ＜ 0.05). Conclusion The preoperative IOP＞21 mmHg and patients' nucleus classification of lens≥Ⅳ degree, patients with high myopia, uveitis, glaucoma, and ultrasound AECP＞7.25 (%×min) are main risk factors for AC exudation after PE combined with IOL implantation in cataract patients. Early prevention and treatment should be taken in clinical practice.
