Aphakia is the absence of the lens of the eye, due to surgical removal, such as in cataract surgery, a perforating wound or ulcer, or congenital anomaly. It causes a loss of ability to maintain focus ( accommodation ), high degree of farsightedness ( hyperopia ), [ 1 ] and a deep anterior chamber .
Aphakic patients do not have a crystalline lens. The crystalline lens is often removed because of opacities called cataracts. The absence of this lens left the patient highly hyperopic (farsighted) in that eye. For some patients the removal was only performed on one eye, resulting in the anisometropia / aniseikonia.
Bullous keratopathy, also known as pseudophakic bullous keratopathy (PBK), is a pathological condition in which small vesicles, or bullae, are formed in the cornea due to endothelial dysfunction.
Aphakic and pseudophakic glaucoma: Aphakic glaucoma is a common side-effect of cataract surgery which causes an increase in IOP. [ 2 ] Corticosteroid -induced glaucoma: Corticosteroids is a risk factor for the development of secondary glaucoma, as there had been increased IOP observed as a drug side-effect.
This is a partial list of human eye diseases and disorders. The World Health Organization (WHO) publishes a classification of known diseases and injuries, the International Statistical Classification of Diseases and Related Health Problems, or ICD-10. This list uses that classification.
A phakic IOL. An intraocular lens (IOL) is a lens implanted in the eye usually as part of a treatment for cataracts or for correcting other vision problems such as near-sightedness (myopia) and far-sightedness (hyperopia); a form of refractive surgery.
Epikeratophakia [1] (also known as epikeratoplasty and onlay lamellar keratoplasty [2]) is a refractive surgical procedure in which a lamella of a donor cornea is transplanted onto the anterior surface of the patient's cornea.
It can be recognized by trembling of the iris (iridodonesis) or lens (phacodonesis) and the presence of an aphakic crescent (an area of the pupil where the lens is absent). [4] Other signs of lens subluxation include mild conjunctival redness, vitreous humour degeneration, prolapse of the vitreous into the anterior chamber, and an increase or ...
