For individuals aged 45 and above who experience challenges in both near and far vision, necessitating the use of glasses, the most optimal choice is refractive lens exchange combined with trifocal lens implantation, provided their eyes are suitable. These implanted lenses offer the capability to achieve clear vision at varying distances—near, intermediate, and far—without reliance on glasses, and they remain in place within your eye throughout your lifetime. The process typically lasts around 12 minutes for each eye and is conducted under local anesthesia, ensuring a painless experience. Following the operation, the only discomfort experienced is a slight stinging during the initial few hours, with no further pain.
