Aphakia
This article is licensed under the GNU Free Documentation License. It uses material from the Wikipedia article "Aphakia" .
Aphakia is the absence of the lens of the eye , due to surgical removal, a perforating wound or ulcer , or congenital anomaly. It causes a loss of accommodation , hyperopia , and a deep anterior chamber. Complications include detachment of the vitreous or retina , and glaucoma .
Aphakic people are reported to be able to see ultraviolet wavelengths that are normally excluded by the lens.[1] This may have had an effect on the colors perceived by artist Claude Monet , who had cataract surgery in 1923.
Treatment
Aphakia could be corrected by wearing glasses , contact lenses or by implant of an artificial lens (pseudophakia ).
