While intraocular lenses (IOL) are used to restore visual acuity in cataract patients, they are limited in their development as no clinically available lens can effectively mimic the accommodative function of the eye's natural lens. The optoelectronic properties of 2D transition metal carbides and/or nitrides (MXenes), including high electronic conductivity, optical transparency, flexibility, biocompatibility, and hydrophilicity, suggest potential use within an accommodating IOL. This study investigates the use of Ti 3 C 2 T x (MXene) as a transparent, conductive electrode to allow changes in optical power. Ti 3 C 2 T x is synthesized and spin-coated on hydrophobic acrylate IOLs, achieving a sheet resistance ranging from 0.2-1.0 kΩ sq −1 with 50-80% transmittance in the visible region. Human lens epithelial and monocytic cells show no cytotoxic nor inflammatory response to the coated lenses. An adjustable focus test cell is fabricated using a liquid crystal (LC) layer sandwiched between Ti 3 C 2 T x coatings on a solid support. Molecular reorientation of the LC layer, through an applied electric field, results in changes in optical power as objects viewed through the test cell appeared in and out of focus. This study is the first step toward the use of Ti 3 C 2 T x within an accommodative IOL design through demonstration of reversible, controlled, adjustable focus.
