Implantable Contact Lenses
What is an Implantable Contact Lens? The implantable contact lens is also known as a phakic IOL. The word “phakos” is Greek for lens of the eye. “IOL” is an abbreviation which stands for “intraocular lens.” An IOL is a lens that is placed inside the eye. The term “phakic IOL” means an artificial lens that is placed permanently inside a the eye to correct nearsightedness and astigmatism without removing the natural lens. The implantable contact lens is made of a proprietary material called Collamer. It consists of collagen and a similar material contact lenses are made out of. The material has built in UV protection and is biocompatible with the eye for long term vision correction. Choosing the EVO ICL for Vision Correction EVO ICLs are designed for nearsighted and nearsighted plus astigmatism for patients who desire reduced dependence or (possibly) elimination of glasses or contact lenses. Patients elect to have the EVO ICL because it does not cause dry eye syndrome and it is an additive technology so no corneal tissue,( the clear front part of your eye), is removed to correct vision. Patients also like the peace of mind that it is removable, so their eye is still their eye. In some cases patients may not be candidates for LASIK due to the anatomy of the eye, but they may be great candidates for the EVO ICL. Who Would Be a Good Candidate for This Procedure? Patients who are nearsighted, with or without astigmatism, and/or those patients who have corneas which are abnormal with respect to being too thin, too flat, or irregularly shaped, would likely be good candidates for the EVO ICL. Also patients considering PRK, but do not want the longer recovery time, might be great candidates for the EVO ICL. The only way to know if you are a candidate for the EVO ICL is to come in for a consultation with your surgeon. We will do a complete analysis of your eyes to determine which vision correction procedure is best for you and your vision goals. What Are the Alternatives to the EVO ICL? The alternatives to correct high amounts of nearsightedness and astigmatism include: Glasses, which are the time tested, tried-and-true method with the highest degree of safety. Contact lenses are also safer than any form of surgery, although there is a small risk of developing a sight-threatening infection and contact lens-related dry eye. Corneal surgery such as LASIK, PRK, LASEK and EPI-LASIK. However, in patients with high degrees of nearsightedness and astigmatism in combination with a thin or flat cornea, it may be impossible to safely achieve full correction of the nearsightedness and/or the astigmatism with corneal surgery. Additionally, the quality of vision with respect to visual acuity as well as contrast acuity may not be as good in the higher degrees of nearsightedness with LASIK, PRK, LASEK or EPI-LASIK as it is with the EVO ICL procedure. What Can I Expect During the EVO ICL Procedure? The procedure for the EVO ICL is performed in our Federally certified ambulatory surgery center in Hayward. This ensures that the highest quality surgery is performed in the safest and most controlled setting using our dedicated surgical team. The surgery itself is quick. Typically, the patient is back in the room for half an hour, but the procedure itself take between 5 to 10 minutes. It is virtually painless and the patient is awake, but relaxed. After using numbing the eye with drops, a small opening is made where the white meets the colored portion of the eye. Additional tiny openings are made to secure the lens safely into position. The lens is then placed through the opening and positioned in the eye. The patient is then observed post-operatively at the center to ensure that the lens is in proper position and that the pressure in the eye is not elevated. Most patients experience an immediate improvement in vision that will continue to improve over the next 24 to 48 hours. What Can I Expect? The data submitted to the FDA for the STAAR EVO ICL lens was based on the results of a multi-center U.S. clinical trial which included 629 eyes followed for up to 6 months. The data showed patients experienced a significant improvement in distance vision. On average patients had a -7.62 refraction and by one month most did not have any remaining refraction and it was stable out to 6 months. In a global survey, 99.4% of patients said they would have the EVO ICL again. With over 2,000,000 implanted worldwide the technology is both safe and effective. What If My Best Possible Vision Before Surgery Is Not 20/20? The FDA studies showed that a small percentage of patients actually enjoyed better vision without glasses than they had with glasses before the procedure. However, one must understand that for most patients the best one can expect is vision without glasses to be the same as the vision with glasses before the procedure.
