Phakic IOLs (intraocular lenses) are an alternative to LASIK and PRK eye surgery for correcting moderate to severe myopia (nearsightedness), and in some cases produce better and more predictable vision outcomes than laser refractive surgery.
Phakic IOLs are clear implantable lenses that are surgically placed either between the cornea and the iris (the colored portion of your eye) or just behind the iris, without removing your natural lens. Phakic lenses enable light to focus properly on the retina for clearer vision without corrective eyewear.
Implantable lenses function like contact lenses to correct nearsightedness. The difference is that phakic IOLs work from within your eye instead of sitting on the surface of your eye.

Also, phakic IOLs offer a permanent correction of myopia, unless the lens is surgically removed.Unlike contact lenses, you can't feel a phakic intraocular lens in your eye (much like you don't feel a dental filling for a cavity) and, apart from regular eye exams, phakic IOLs typically do not require any maintenance.
Phakic IOLs vs. LASIK Eye Surgery
LASIK currently is the most popular type of refractive surgery in the United States. It is safe and effective, and technology advances such as custom LASIKand bladeless LASIK have made visual outcomes even better.
But not everyone is a good candidate for LASIK surgery. Potential reasons for not being a good LASIK candidate include: having too much nearsightedness, farsightedness or astigmatism; having an unusually thin or irregularly shaped cornea; and having eye conditions such as keratoconus or dry eye syndrome.People with moderate to severe nearsightedness may be better suited for phakic IOLs than LASIK surgery.
For many people who are outside the treatment range of LASIK, phakic intraocular lenses can produce excellent results. implantable lenses typically are somewhat higher than the cost of LASIK. If your surgeon recommends a phakic IOL over LASIK, it may be prudent to not let cost cloud your decision to follow your surgeon's advice.After a thorough eye exam and health evaluation, your eye surgeon will advise on the best type of surgery for you.
