Abstract Details


Nanophthalmos presents an array of challenges even to seasoned cataract surgeons.Extreme axial hyperopia, high dioptric IOL requirements, shallow anterior chamber and severe positive pressure may complicate lens implantation. We demonstrate a 71 year old patient with bilateral nanophthalmos who had uneventful cataract extraction in the right eye with primary implantation of 2 intraocular lenses (IOLs) of 2 different materials


Aravind Eye Hospital, Coimbatore


We report a case of primary piggyback intraocular lens implantation in the right eye of a 71 year old male with bilateral nanophthalmos. Patient had an axial length of 16.56mm, lens thickness of 5.66mm and a calculated IOL power of 50.50D. Patient underwent a combined clear corneal phacoemulsification and superior sclerocorneal tunnel approach to implant a foldable acrylic and a rigid PMMA intraocular lens into the capsular bag. Calculated IOL power being higher than the available highest power for a single intraocular lens by 10D a piggyback implantation was done.


Patient preoperatively had an uncorrected vision of 2/60 (1.4 LogMAR) improving to 6/60 (1 LogMAR) with sphere of 흀� and cylinder of � in his right eye. Immediate post operative period patient had an uncorrected vision of 5/60 (1.1 LogMAR) and a pinhole vision of 6/60 (1 LogMAR).


Primary piggyback intraocular lens implantation gives better visual acuity in very high IOL power patients especially in a scenario where a custom intraocular lens is unavailable. Piggyback surgery gives the patient better uncorrected visual acuity than implantation of single IOL of maximum available power.
