Differences Between IOL and ICL
IOL and ICL surgery are used to treat a variety of vision conditions, but they are different in what they treat and who is a candidate.
The main difference is that an ICL, or implantable contact lens, is an artificial collamer lens implanted behind a patient’s iris and in front of the natural lens, while an IOL, or intraocular lens, replaces the natural lens.
ICL is similar to LASIK in that it is a vision correction surgery to improve refractive errors such as nearsightedness and astigmatism. For some patients who cannot have LASIK due to thin corneas or high prescriptions, ICL is seen as a LASIK alternative.
IOLs, on the other hand, are used primarily in cataract surgery. Cataract surgery and Refractive Lens Exchange (both types of IOL procedures) are often better for patients over the age of 40 who do not qualify for LASIK, PRK, or ICL surgery.
