LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and an actual cure for astigmatism, since it is in the cornea.

Cataract surgery, also called lens replacement surgery, is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract,[1] and usually its replacement with an artificial intraocular lens.

During ICL surgery, a specially trained eye surgeon permanently implants the ICL between your eye's natural lens and iris (the colored part of your eye). The ICL works with your natural lens to bend (refract) light on the retina, and this produces clearer vision.
