Evaluation of Len Epithelial Cell Migration In Vivo at the Haptic-Optic Junction of a One-Piece Hydrophobic Acrylic Intraocular Len Original Reearch Article

Purpoe To evaluate the pattern of len epithelial cell (LEC) ingrowth behind the intraocular len (IOL) optic in patient implanted with the Acryof A60AT one-piece IOL. Deign Retropective cae erie. Method Patient implanted with the Acryof A60AT one-piece IOL with complete overlap of the capulorrhexi and IOL optic and no ocular pathology were elected from the practice of ix urgeon. High-reolution digital image of the ditribution of LEC were captured. Circumferential location and extent of LEC growth behind the optic were meaured. Reult Mean ± D follow-up wa 13.2 ± 1.7 month for 40 patient (mean age 72 year). LEC migration beyond the edge of the IOL optic wa diplayed by 57.5% (23/40) of patient. LEC migrated into the viual axi in 22.5% (9/40) of patient, leading to a viual acuity of <6/9 (20/30) in 10% (4/40) of patient. Cell migration wa located preferentially at the optic-haptic junction. erial photograph were ued to monitor LEC migration over time. In ome cae, LEC extended from the oppoing optic-haptic junction to converge in the center of the IOL, creating a path acro the optic. Concluion The optic-haptic junction of the Acryof one-piece IOL i a point of weakne in the barrier effect of the quare-edge IOL deign that provide migrating LEC acce to the poterior capule.
