Epidemiology
Autopsy studies indicate that 6-25% of the U. S. population have small pituitary tumors. Forty percent of these pituitary tumors produce prolactin, but most are not considered clinically significant. Clinically significant pituitary tumors affect the health of approximately 14 out of 100,000 people. In non-selective surgical series, this tumor accounts for approximately 25-30% of all pituitary adenomas. Some growth hormone (GH)–producing tumors also co-secrete prolactin. Microprolactinomas are much more common than macroprolactinomas. See also

Deep anterior chamber: Since lens is absent, anterior chamber will be deep. Iridodonesis: Iridodonesis is the vibration or agitated motion of the iris with eye movement. Purkinje test shows only two images; the reflection from anterior and posterior corneal surfaces. Iridectomy mark may be seen in surgical aphakia. Astigmatism: With-the-rule astigmatism due to corneal wound healing may occur in surgical aphakia, mainly after ICCE or ECCE. Complications
Main complications of surgical aphakia include:

Spectacle intolerance: Due to image magnification (up to 30%), optical aberration, prismatic effect and roving ring scotoma, spectacles are not well tolerated by aphakic patients. Due to high anisometropia, spectacle correction in uniocular aphakia may cause diplopia. Glaucoma: Secondary angle closure glaucoma may occur due to vitreous prolapse. Retinal detachment
Aphakic bullous keratopathy

Treatment
Aphakia can be corrected by wearing glasses, contact lenses, artificial lens implantation, or refractive corneal surgeries. Eye with artificial lenses are described as "pseudophakic". Etymology
Gr. a- alfa priv + phakos, lens, anything shaped like a lens
