The efficacy of surgery for removal of intraocular lens which prolapsed into vitreous

Objective To evaluate the surgical efficacy of surgery for removal of posterior chamber intraocular lens which prolapsed into the vitreous. Methods From Oct. 2012 to Oct. 2017, the data of 16 eyes of 16 patients with intraocular lens prolapsed into vitreous were analyzed restropectively. The cause was ocular contusion in 11 eyes, after cataract surgery without history of trauma in 5 eyes. The best corrected visual acuity before operation was CF-0.1. Vitrectomy was performed via the standard pars plana closed incision. The perfluorocarbon liquid of 0.5-3.5 ml was injected during operation, and intraocular lens was removed through the tunnel of the corneal limbus. All cases received IOL suture fixation in the ciliary sulcus.The postoperative visual acuity, intraocular pressure, intraocular lens position and complications were observed. Results The intraocular lens were successfully removed in 16 eyes. Thirteen eyes received the posterior chamber intraocular lens with ciliary sulcus suture fixation in one stage, and the visual acuity was improved. The best corrected visual acuity was 0.1-0.5. Postoperatively hypotony occurred in 1 eye, hypertension occurred in 3 eyes, and the intraocular pressure returned to normal after drug treatment. No complication such as intraocular lens decentration or dislocation, suture knot exposure or vitreous hemorrhage occurred. Conclusion Vitrectomy combined with intraocular lens removal and ciliary sulcus stature fixation for the treatment of the intraocular lens prolapsed into the vitreous can obviously improve visual acuity and prevent complications.
