The Visian ICL is also known as the implantable collamer lens. It is in other words an implantable contact lens, and a type of refractive procedure to help correct myopia or shortsightedness. The Visian ICL is typically selected for patients in whom LASIK is not possible or contraindicated. With the advent of the Visian ICL, candidates with very high refractive errors or very thin corneas can successfully get rid of constant wear glasses.
The Visian ICL is made of Collamer®, a highly biocompatible advanced lens material which contains a small amount of purified collagen. Collamer does not cause a reaction inside the eye and contains an ultraviolet blocker that provides protection to the eye. Collamer is a material proprietary to STAAR Surgical Company.
Good candidates for the Visian ICL include patients who:
- Are between the ages of 21 and 45.
- Are nearsighted, including those with mild, moderate, and severe myopia (as low as -3D to as high as -20D prescription) with or without astigmatism.
- Have dry eyes, severe myopia, or a thin cornea (non-LASIK candidate).
- Have mild to moderate stable keratoconus
- Have sufficient anterior chamber depth and acceptable endothelial cell density (this will be determined by your ophthalmologist after a comprehensive eye scans).
- Have not had a change in their eyeglass prescription of more than 0.5D in a year.
- Have otherwise healthy eyes
- Are not currently pregnant or nursing.
- Do not suffer from uncontrolled hormonal or immunological disorders.
The Visian ICL is surgically inserted by a CERTIFIED surgeon through a small micro-incision and placed just behind the iris in front of the eye’s natural lens. The Visian ICL is designed to stay in position after surgery with no extra post-operative care.
No, most patients state that they are very comfortable throughout the procedure. You will undergo treatment while under a light topical anesthetic drops or local anesthetic. Your ophthalmologist may choose to administer a light sedative as well.
The implantation procedure for the Visian ICL involves a procedure similar to that of cataract surgery. The main difference is that, unlike cataract surgery, the Visian ICL procedure does not require the removal of the eye’s crystalline lens. And unlike the LASIK or PRK refractive procedures, the Visian ICL procedure does not involve the removal of corneal tissue. The Visian ICL procedure is a short 15 minute SURGICAL procedure that involves several important steps.
Within 24 hours of undergoing the Visian ICL surgery, you will have a follow-up visit with the ophthalmologist. The surgeon will monitor the vision and intraocular pressure and will discuss your progress. Patients need to follow physician instructions, especially regarding the needed use of antibiotics and anti-inflammatory medications during the week following the procedure. Following surgery, you may use prescription eye drops or oral medication. The day after surgery, you will return to your surgeon for a follow-up visit. You will also have follow-up visits one week, one month and preferably 3 and 6 months following the procedure
Patients should contact their eye surgeon immediately if they experience severe eye pain or a sudden decrease in vision. Improved vision may be evident the same day as the Visian ICL procedure, and you can expect a quick visual recovery.
Although the Visian ICL is intended to remain in place permanently, your surgeon can and may have to remove the implant if necessary.
No. The Visian ICL is positioned behind the iris (the colored part of the eye), where it is invisible to both you and observers. Only your surgeon will be able to tell that vision correction surgery has taken place.
