Secondary intraocular lens implantation after glaucoma drainage device surgery in childhood glaucoma associated to congenital cataract surgery : a case series

Abstract

Objective: To report the results of secondary Intraocular Lens (IOL) implantation in aphakic children with secondary glaucoma who had previously undergone Ahmed valve implantation via pars plana for glaucoma control. Methods: Three children with bilateral congenital cataract who underwent lensectomy with anterior vitrectomy without IOL developed secondary glaucoma in only one eye of each patient. In order to control glaucoma, patients underwent posterior via pars plana vitrectomy with Ahmed drainage device implantation placed in the superior temporal quadrant. Results: All patients achieved intraocular pressure control, with or without topical medication after glaucoma device surgery. After a minimum of six months of follow-up they underwent secondary IOL implantation in the scleral sulcus, using the remaining capsular bag as support. All children improved their quality of life after IOL implantation and maintained glaucoma stability. Conclusion: This case series demonstrates the possibility of secondary IOL implantation in aphakic children previously treated with Ahmed implant device with the device placed via pars plana, maintaining glaucoma control with the best optical correction for aphakia.
