Phakic Intraocular Lens (PIOL)
Intraocular contact lens (IOL) is a type of lens that is implanted inside the eye. Replacing the existing crystalline lens because it has been clouded by cataract or a form of surgery used to change the optical power of the eye.
What is Phakic Intraocular Lens?
Phakic intraocular lens (PIOL) or Phakic lenses are thin lenses made of plastic and silicone that is implanted inside the eye to correct extreme nearsightedness or farsightedness without removing the eye&'s natural lens. It can either be spheric or toric. Toric PIOL&'s has to be inserted in a specific angle to avoid astigmatism to get worse. The lenses become an internal contact lens rather than contact lenses on the surface of the eye. Phakic intraocular lens is recommended for patients whose visual correction is outside the range that can be safely treated by Lasik surgery (laser refraction surgery).
This type of contact lens implant is ideal for patients who are young and for those who are in their 30&'s to 40&'s. Phakic intraocular lens is recommended for people having myopia (shortness of sight), since their eyes are still elastic and can still accommodate. These implants are placed in either two locations in the eye:
What does Phakic Intraocular Lens treat?
Phakic intraocular lenses are used to correct refractive errors, problems in the eye&'s focusing power. Ideally, Phakic intraocular lenses causes light entering the eye to focus on the retina (light-sensitive membrane in the back of the eye), thus, providing clear distance vision without needing to wear eyeglasses or contact lenses. Unlike customary contact lenses, one cannot feel the Phakic intraocular lens in your eye/s. Also, no maintenance is required for this kind.
How Phakic Intraocular Lens is done
Before the surgery, numbing eye drops are placed in the eye. An instrument is ascribed to hold the eyelids and then an incision is made in the eye then placed just in front or behind the iris.
Can they be removed?
Phakic intraocular lenses are permanent. While the lenses can be removed by surgery, the return to you previous level of condition or vision of the eye can not be guaranteed.

What are the risks of Phakic Intraocular Lens?
Having Phakic intraocular lens involves surgery, so there are risks involved. That is why it is very important to fully understand the restrictions and potential risks of having Phakic intraocular lens implant surgery.
