Implantable Collamer Lens
LASIK Eye Surgery today is a safe and effective method of correcting nearsightedness, farsightedness and astigmatism for the vast majority of patients seeking Laser Vision Correction of their refractive eye conditions. In fact, LASIK surgery is by far the most common procedure to help those wishing to eliminate their dependence on eyeglasses and contact lenses. However, for some patients who are extremely nearsighted or myopic, those that have thin corneas or those that have other conditions that might predispose them to complications with LASIK, another alternative might be to find out if they are good candidates for Implantable Lenses to correct their vision. One such lens is the Verisyse Phakic Intraocular Lens and another is the VisianT Implantable Collamer Lens (ICL).
The Implantable Collamer Lens is designed for :
. the correction of myopia ranging from -3 to -15 diopters (D) with less than or equal to 2.5D of astigmatism at the spectacle plane,
. the reduction of myopia ranging from -15D to -20D anterior with less than or equal to 2.5D astigmatism at the spectacle plane,
. adults 21-45 years of age with an anterior chamber depth (ACD) of 3.00 mm or greater, and a stable refractive history within 0.5D for 1 year before implantation.
We at Bansal eye hospital is an authorized center for ICL. Through ICL we have achieved spectacle freedom in many of our patients who were unfit for laser vision correction.
Common Questions About the Implantable Collamer Lens : –
. Who is a candidate for the ICL?
The best candidates for the Visian ICL are between the ages of 21 and 45, with moderate to severe myopia. It is best if the patient has not had any previous eye surgery and does not have any previous history of eye disease such as glaucoma, iritis or diabetic eye disease.
. What are the advantages of the ICL?
The Visian ICL is capable of correcting a wide range of nearsightedness without the need to remove corneal tissue. When properly implanted, the ICL provides predictable results and quality of vision due to its position inside the eye, as well as its optical characteristics. The lens is made of a biocompatible lens material called Collamer which is well tolerated by the eye.
. What if my vision changes?
If there are major changes in your vision, the Visian ICL can easily be removed and replaced, or another procedure can be done at any time. With the ICL, one can still wear glasses or contact lenses if necessary and may even be able to have LASIK or another refractive procedure to fully correct their vision. The ICL does not prevent or help presbyopia, or the need for reading glasses due to age.
. Does the ICL dry out or get dirty like a contact lens?
No. ICL is designed to remain in place within the eye without maintenance. An yearly examination by your eye surgeon is recommended to make sure that everything is unchanged and well tolerated.
. Can the ICL be seen by the naked eye?
No. Because the ICL is placed behind the iris, neither you, nor an observer will be able to see the lens in place. The visual appearance of the ICL is unnoticeable, and there is no way for anyone other than a trained professional to see that the ICL is in place.
. What is involved in the ICL procedure?
The ICL implant surgery is performed on an outpatient basis, which means that you can have the implant surgery and go home the same. As with any surgery someone will have to drive you to and from surgery. Either numbing drops and/or a local injection will be administered so that there is very little discomfort and normally no pain associated with the implant procedure. Some drops or perhaps oral medication may be prescribed and a visit is usually scheduled the day after surgery.
. How long can the ICL stay in the eye?
The ICL is intended to remain in place without maintenance. If it becomes necessary, for any reason, it can be easily removed by a trained eye surgeon.
. Can the ICL be felt once it is in place?
The ICL is not usually noticed by the patient once it is implanted. It does not attach to any tissues within the eye and does not move after it implanted.
