Abstract: Objective To compare the incidence of posterior capsule opacification (PCO) after surgery in the patients with different types of cataract. Design Retrospective case series. Participants 2069 eyes that accepted phacoemulsification and intraocular lens implantation by the same ophthalmologist from 2007 to 2008 in the First Hospital of Shijiazhuang. In which, 1574 eyes with simply senile cataract, 305 eyes with diabetic cataract, 165 eyes with cataract combined with high myopia, and 25 eyes with uveitis complicated cataract. Method The incidences of PCO in the patients with various types of cataract were recorded through observing visual acuity, split lamp and ocular fundus for 2 years after operation. The PCO was classified according to Hayashi's method. Main Outcome Measures The incidence of PCO in patients with various types of cataract. Results In simply senile cataract group, diabetic cataract group, uveitis combined cataract group and high myopia combined cataract group, the incidence of PCO was 8.13% (128 eyes), 12.79% (39 eyes), 16.00% (4 eyes) and 21.82% (36 eyes), respectively (χ2=35.377, P=0.000). The incidence of 1 level PCO among 4 groups was similar, 60 eyes/3.81% in simply senile cataract group, 6 eyes/1.97% in diabetic cataract group, 1 eye/4.00% in uveitis combined cataract group, and 5 eyes/3.03% in high myopia combined cataract group. The incidence of 2 level PCO in diabetic cataract group was higher (20 eyes/6.56%) and the incidence of 3 level PCO in high myopia combined cataract group was higher (24 eyes/14.55%) than in the other groups. Conclusion The incidence of PCO postopteratively in simply senile cataract group was significantly lower than other groups, but in high myopia combined cataract group was higher and the PCO was denser.
