If you dislike wearing glasses and you are not a suitable candidate for laser eye surgery, then implantable contact lenses (ICL’s) may offer the permanent vision correction that you require.
Implantable contact lenses basically work in exactly the same way as standard/external contact lenses do. ICL’s alter the shape of the cornea in order to correct refractive errors such as near and far-sightedness, and astigmatism. However, unlike non-permanent contact lenses, ICL’s are surgically placed inside the eye rather than over the top of it.
Implantable contact lenses are also sometimes known as phakic intraocular lenses (IOL’s). The reason for this is because the two share a number of characteristics. IOL’s are seen in cataract surgery where they take the place of the affected natural lens after it has been removed. However, when used as implantable contact lenses they work in conjunction with the natural lens of the eye in order to correct your vision.
The procedure requires your surgeon to make a tiny incision in to the cornea to allow access to the natural lens underneath. The ICL is then inserted through the incision and placed either in front of or behind the iris which is the colored part of your eye, and in front of the natural lens. The incision into the cornea is able to heal naturally without stitches, and the entire process is extremely quick.
Your surgeon will give you anesthetic, usually in the form of eye drops, ahead of the procedure and as such you should experience very little, if any, discomfort.
