·AIM:To compare the effect of ciliary sulcus sutured intraocular lens surgery and anterior chamber intraocular lens implantation for posterior capsule rupture of cataract.·METHODS:The retrospective analysis involved the ciliary sulcus sutured intraocular lens surgery,anterior chamber intraocular lens implantation for cataract posterior capsule rupture of 45 cases of 45 eyes.The efficacy of surgery was compared with the two groups.·RESULTS:Ciliary sulcus sutured intraocular lens surgery group and the anterior chamber intraocular lens implantation group can effectively cure capsular rupture after cataract treatment.But the latter had two cases of postoperative iridocyclitis and the elevation of intraocular pressure after six months and visual acuity improvement of the rest.The former had all visual acuity improved,and no obvious complications.·CONCLUSION:Ciliary sulcus sutured intraocular lens surgery and anterior chamber intraocular lens implan-tation in cataract surgery can be effective in the treatment of posterior capsule rupture and improve eyesight,but the former is closer to physical location with fewer postoperative complications.·
