Patients with cataracts undergo corrective surgery to restore visual acuity however the replacement intraocular lens (IOLs) does not provide true accommodative function and patients require spectacles for near vision. MXene is a 2D nanomaterial with transparent and conductive properties that lend itself to application in optoelectronic devices. Nevertheless, the effect of MXene on posterior capsular opacification (PCO), the most common complication of cataract surgery, is unknown. My PhD will focus on the impact of MXene on lens epithelial cells' proliferation, migration and differentiation and the key pathways that lead to PCO.
