Sutureless and Intrascleral-fixed Intraocular Lens Implantation for Patients with Capsular Coloboma

Objective:To investigate the surgery of secondary posterior chamber intraocular lens implantation in special cases of capsule coloboma.Method:Nineteen eyes of 19 patients with capsule coloboma underwent secondary posterior chamber intraocular lens implantation which were fixed in the intra sclera and sutureless,the folded three-pieces of intraocular lens were injected into the posterior chamber through the incision on the clear cornea,the loops passed out though the scleral flap 2 mm after the limbus and went into the pre-made scleral tunnel incision.Postoperative followup included intraocular pressure,best-corrected visual acuity,IOL stability,and other postoperative complications for over 6 months.Result:Nineteen eyes of 19 patients were involved in the study,visual acuity after surgery was better than 0.6 in 13 eyes,between 0.2 and 0.6 in 6 eyes,all patients experienced obvious vision improvement with normal intraocular pressure,the IOLs were centered without tilt or decentration,no severe complications such as endophthalmitis,low intraocular pressure,coneal decompensatory were observed during the follow-up.Conclusion:Sutureless intrascleral posterior chamber intraocular lens implantation is a reliable and effective therapy for eyes without posterior capsular support.
