Abstract Details

Purpose:

Study of the biomechanical and optical properties of several IOLs

Setting:

Center for Education and Research on Macromolecules, University of Ličge (Ličge, Belgium)

Methods:

Eleven benchmark foldable IOLs, IPURE, PODEYE, Acrysof SN60WF, EnVista, Sensar AR40e, Tecnis ZCB00, Isert Model 251, AF-1 YA-60BB, Fine Vision, Acri.Tec 366D and Ioflex, were tested by standard analytical methods for biomechanical, rheological and optical investigations under identical conditions

Results:

With one exception, IOLs equilibrated in aqueous medium, demonstrated lower glass transition temperature, higher deformability, lower injection forces and complete recovery of their initial optical properties after injection. Typical hydrophobic acrylic dry-packaged lenses required higher injection forces with high residual deformation and lost part of their initial optical quality after injection. Hydrophobic acrylic C-loop, double C-loop and closed quadripode haptics applied optimal compression forces to the capsular bag with negligible optic axial displacement and tilt, compared to plate and PMMA haptics

Conclusions:

The combination of the C-loop haptic and the bioadhesive glistening-free GF hydrophobic acrylic material (IPURE lens), allows for the fabrication of biomechanically stable IOLs. The same material used in association with double C-loop haptic (PODEYE lens) design facilitates the per-operative manipulation and placement of the IOL in smaller size capsular bag without impairing the other biomechanical properties of a single-C-loop design.
