Observation of first intraocular lens implantation about the posterior capsule rupture in small incision cataract surgeries

Objective To investigate the reasons and treatments of the posterior capsule rupture in small incision cataract surgeries.Methods Retrospectively analyzed 86 eyes of 74 diabetic cataract patients with small incision cataract surgery,in which 24 eyes were of posterior capsular rupture,vitreous loss,and with anterior vitrectomy and intraocular lens implantation.Results The probabiliy of posterior capsule rupture in this group was 27.9%,and all eyes were operated by the first posterior chamber intraocular lens implantation,including 2 cases were operated by intracapsular fixation,and 8 cases were operated by ciliary sulcus implantation,and 14 cases were operated by suspensive intraocular lens implantation.Follow-up 1 to 24 months,and after the surgery,visual acuity were improved significantly without serious complications.Conclusion Ciliary sulcus fixation and suture fixation of posterior chamber intraocular lens are valid treatments for first intraocular lens implantation about the posterior capsule rupture in small incision cataract surgeries.
