ICL, or Implantable Collamer Lens, is a procedure for those who seek a permanent solution to myopia (nearsightedness) but are not candidates for LASIK or PRK. It involves placing a biocompatible lens between the iris and the natural lens, allowing light to focus correctly on the retina and enhancing vision. ICL is reversible, provides UV protection, and is an ideal option for patients with thin corneas or high levels of myopia.
