Factors Of Posterior Capsule Opacification After Congenital Cataract Surgery

Objective:To analysis the relevant factors of posterior capsular opacification a fter congenital cataract surgery. Methods:In the clinical trial of52patients with c ongenital cataract (87eyes), age ranging from3months to12years old with an a verage age of4.7years old, were retrospectively analyzed. Of them, phacoemulsific ation (Phaco) with posterior continuous curvilinear capsulorhexis (PCCC) were perf ormed in22patients (30eyes). PCCC with an anterior vitrectomy (AV) in30pati ents (57eyes). And primary intraocular lens (IOL) implantation in19patients (27e yes), aphakia15cases (27eyes), and secondary IOL implantation in18patients (33eyes). Patients were followed-up for6months to observe the change of posterior capsule. Results:during a followed-up of6months, PCO occurred in18eyes (20.69%), including PCCC in11(36.67%) eyes, PCCC+AV in7(12.28%) eyes, statistic al analysis,χ-=7.123,P<0.05, there were significant difference between the two groups; including primary IOL implantation in5(18.52%) eyes, aphakia in5(18.52%) eyes, and secondary IOL implantation in8(24.24%) eyes, statistical analysis, χ2=0.409, P>0.05, there were no significant difference among the three groups; i ncluding the age under2year in13(36.11%) eyes, over2years old in5(9.80%) e yes,χ2=8.901, P<0.05, there were difference between the two groups. Conclusion PCO is related with surgical approach and age at surgery. Compared with Phaco+PCCC, there were a lower incidence of PCO in Phaco+PCCC+AV. And, the young er at surgery, the higher incidence of PCO.
