Phakic implants or Intraocular lenses (IOLs) are clear implantable lenses implanted inside the eye to enhance its refractive power. They are surgically placed in either the anterior chamber (between cornea and iris) or the posterior chamber (between iris and crystalline lens) It is a very effective, safe and reliable procedure for suitable candidates.
Phakic IOLs is utilised in patients between eighteen and fifty wherever the patient who have a higher visual impairment than that which can be corrected with laser surgery and for those who are unsuitable for laser surgery.
These lenses function like contact lenses, the difference is that they work from within your eye instead of sitting on the surface of your eye


Conditions associated 


Myopia is a common refractive condition commonly referred to as near or short sightedness. People with Myopia can see near objects clearly but distant objects are blurry. Myopia occurs when the cornea and lens focus the light in front of the retina instead of exactly on it, usually because the eye is a little larger than it should be.  


Hypermetropia is a common refractive condition of the eye in which vision is better for distant objects than for near objects. It can be called far-sightedness or hypermetropia. 

It results from the eyeball being smaller than average, causing images to be focused behind the retina. In hypermetropia, the light is focused too far back in the eye, behind the retina, which causes things to look blurred close-up.
