The absence of the lens of the eye is known as Aphakia. The lens is transparent and it is situated behind the iris which is the colored part of the eye. Aphakia may be caused due to surgical removal, a perforating wound or ulcer or congenital reasons. It affects far sightedness (hyperopia) along with complications of detachment of the vitreous or retina and glaucoma.
HOW IS APHAKIA DIAGNOSED?
A specialist from the Ophthalmology department can diagnose this condition with the help of a detailed eye examination in a properly illuminated room. Also, with a focused light, the specialist can take a look at the eye to see whether or not the lens is present and functioning properly. A physical examination based on the symptoms can also be carried out. The specialist can check for iridodonesis, or hypermetropic fundus.
HOW IS APHAKIA TREATED?
The treatment of Aphakia is done by correction of the eye by wearing glasses, contact lenses or by implant of an artificial lens. Treatment of babies with Aphakia may involve the use of special contact lenses as they are safe for baby to sleep in and they can be used for a longer duration.
DID YOU KNOW?
People with aphakia have relatively small pupils and their pupils dilate to a lesser degree.
