AIM: To investigate the incidence and related factors on effusion of anterior chamber(AC)after phacoemulsification(PE)combined with intraocular lens(IOL)implantation.

METHODS: Totally 359 cases of cataract(375 eyes)underwent PE combined with IOL implantation were collected in our hospital. The incidence of AC exudation after operation and related factors were analyzed by single factor and multiple logistic regression analysis.

RESULTS: The group was included in 359 cases(375 eyes). The incidence of postoperative AC exudation in the study group was 5.9%(22/375). The preoperative intraocular pressure(IOP), visual acuity before and after surgery, nuclear grades, posterior capsular rupture(PCR)rate and ultrasonic accumulated energy complex parameter(AECP)of the study group showed statistically significant difference compared with the control group(all P<0.05). The results of univariate factor analysis showed that high myopia, glaucoma, uveitis, preoperative visual acuity <1, the incidence of intraoperative PCR, preoperative IOP>21mmHg, intraoperative pupil diameter <3mm, ultrasonic AECP >7.25(%×min), the lens nucleus grade ≥ IV were risk factors of AC exudation after PE combined with IOL implantation in patients with cataract(all P<0.05). The multivariate logistic regression analysis showed that high myopia, glaucoma, uveitis, the lens nucleus grade ≥ IV, the incidence of intraoperative PCR, preoperative IOP >21mmHg, ultrasound AECP >7.25 were independent risk factors of AC exudation after PE combined with IOL implantation in patients with cataract(all P<0.05).

CONCLUSION: High myopia, glaucoma, uveitis, the lens nucleus grade ≥ IV, the incidence of intraoperative PCR, preoperative IOP>21mmHg, ultrasonic AECP>7.25 are independent risk factors of AC exudation after PE combined with IOL implantation in patients with cataract, with such risk factors in patients with cataract should be paid closely attention and timely diagnosis and treatment in clinic.
