Clinical Study of Secondary Intraocular Lens Implantation

Background Secondary implantation of lens is an insertion of a lens in any eye rendered aphakic by trauma or previous surgery. Aims and objectives To study and analyse the result of secondary IOL implantation Materials and methods This is a hospital based clinical study of 12 patients with aphakia attending the ophthalmology out patient department of our Hospital. These cases were treated surgically with secondary iol implantation and then results were analysed with respect to study of indications for secondary IOL implantation, the functional outcome following secondary IOL implantation and to understand the reason for poor visual acuity following secondary IOL implantation. Result 12 patients underwent secondary IOL implantation. All were in the age group of 61 to 70.83.33 % of patients had pseudophakia as the status of the other eye and 16.66 % had aphakia in fellow eye. Monoocular aphakia with pseudophakia in fellow eye was the indication for secondary IOL implantation.41 % underwent ACIOL implantation, 41 % underwent Scleral fixative and 16 % underwent PCIOL implant in sulcus.75 % eyes had BCVA 6/12 or better and 25 % had BCVA 6/24 or better. Striate keratopathy in 25 %, uveitis in 33.33 % and Cystoid macular edema in 8.33 %. Interpretation and conclusion Majority of patients seeking IOL implantation have monocular aphakia with good vision in the fellow eye. ACIOL and PCIOL have comparable results as per post operative visual acuity is concerned. Hence secondary IOL implantation is a good surgical option for patients with aphakia seeking to overcome their aphakic disability.
