Laser eye surgery involves permanent changes to the cornea, the clear dome-shaped surface of the eye, and is particularly suitable for myopia, hyperopia 1, and astigmatism. While laser eye surgery is designed to last a lifetime, age-related vision changes may lead to the need for further enhancement to accommodate age-related changes.
Lens implant surgery, usually reserved for older patients, is permanent following lens replacement (RLE) procedures, however, implantable contact lenses (ICLs) may be removed and replaced with a new ICL if required.
