Aphakia
Aphakia
Aphakia (pronounced: /əˈfeɪkiə/) is a medical condition characterized by the absence of the lens of the eye, due to surgical removal, a congenital anomaly, or a traumatic event. It can occur in one or both eyes.
Etymology
The term "Aphakia" is derived from the Greek words "a" meaning "without" and "phakos" meaning "lens".
Symptoms
People with aphakia often experience blurred vision, glare, and have a decreased ability to focus on close objects (a condition known as presbyopia). They may also have an increased sensitivity to light, known as photophobia.
Treatment
Treatment for aphakia typically involves the use of corrective lenses, either in the form of glasses or contact lenses. In some cases, intraocular lens (IOL) implantation may be performed during or after the removal of the natural lens.
