Recent advances in the design and incorporation of 2D materials, specifically transition metal carbides, paves the way for controlled, adjustable focus restoration following cataract surgery. Henniker plasma systems are utilised to clean and activate the surface of intraocular lens materials (IOLs) in order to produce a well-adhered, uniform coating on the lens.

2D Titanium Carbide (Ti3C2Tx) in Accommodating Intraocular Lens Design

Abstract

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 Ti3C2Tx (MXene) as a transparent, conductive electrode to allow changes in optical power. Ti3C2Tx 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 Ti3C2Tx 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 Ti3C2Tx within an accommodative IOL design through demonstration of reversible, controlled, adjustable focus.
