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 (), [1] and a deep anterior chamber.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4]
0.6% risk of retinal detachment, 0.6% risk of cataract (other studies have shown a risk of 0.5–1.0%), and; 0.4% risk of corneal swelling. Other risks include: [citation needed] 0.03–0.05% eye infection risk, which in worst case can lead to blindness. (This risk exists in all eye surgery procedures and is not unique to IOLs.) glaucoma ...
Intraocular lenses that are implanted into eyes after the eye's natural lens has been removed during cataract surgery are known as pseudophakic. Phakic intraocular lenses are indicated for patients with high refractive errors when the usual laser options for surgical correction ( LASIK and PRK ) are contraindicated.
Irvine–Gass syndrome, pseudophakic cystoid macular edema or postcataract CME is one of the most common causes of visual loss after cataract surgery. [ 1 ] [ 2 ] The syndrome is named in honor of S. Rodman Irvine [ 3 ] [ 4 ] and J. Donald M. Gass .
Particular risk factors are younger age, male sex, longer axial length, and complications during surgery. In the highest risk group of patients, the incidence of pseudophakic retinal detachment may be as high as 20%. [64] The risk of endophthalmitis occurring after surgery is less than one in 1000. [65]
In 10%-15% of the cases these will appear in a classic smokestack shape. [citation needed] Differential diagnosis should be immediately performed to rule out retinal detachment, which is a medical emergency. A clinical record should be taken to keep a timeline of the detachment.
Retinal detachment: NOS; without retinal break Excludes: central serous chorioretinopathy (H35.7) (H33.3) Retinal breaks without detachment Horseshoe tear of retina, without detachment; Round hole of retina, without detachment; Operculum; Retinal break NOS Excludes: chorioretinal scars after surgery for detachment (H59.8) peripheral retinal ...
