The ICL is designed to be a permanent correction for nearsightedness. However, a benefit of the ICL lens is that it can be removed if the need ever arises or if your vision changes, additional correction may be performed through laser vision correction (candidacy required).
Since being approved in 2005 by the FDA, over 800,000 successful ICL procedures have been performed. The soft and flexible lens is made from a bio-material called collamer which will not be rejected by the body as a foreign object or cause any reactions.
Additional benefits include a reduced risk of dry eyes when compared to LASIK, because corneal nerves are not disturbed during the procedure. The ICL also provides UV protection to the inner eye!
However, there are always risks with any surgery. Risks, although low, include infection, increased intraocular pressure, earlier onset of cataracts, among others. Your surgeon will discuss all risks with you during your exam.
One of the most significant differences in the vision correction procedures is that the ICL implant is an option for those who may not be a candidate for LASIK due to thin corneas or a nearsighted prescription that is out of range for LASIK to correct. On the other hand, LASIK is approved to correct more visual irregularities including farsightedness and nearsightedness with or without astigmatism.
In addition, while the ICL procedure is more invasive than LASIK, unlike LASIK it is reversible and has a lower risk of dry eye related to the procedure.
