Currently available foldable or injectable IOL biomaterials include hydrophilic acrylics, hydrophobic acrylics and silicones. The selection criteria for an IOL biomaterial depend upon: • The effect on the blood aqueous barrier • The cellular reaction on the anterior surface of the lens • The effect of the IOL biomaterial on the lens capsule in terms of lenticular epithelial cell (LEC) proliferation and metaplasia leading to anterior and posterior capsular opacification. Rayacryl®, being a hydrophilic acrylic, consistently outperforms all other biomaterials in terms of the above criteria.
