Posterior capsular opacification, also known as after-cataract, is a condition in which months or years after successful cataract surgery, vision deteriorates or problems with glare and light scattering recur, usually due to thickening of the back or posterior capsule surrounding the implanted lens, so-called 'posterior lens capsule opacification'.
Posterior capsular rupture, a tear in the posterior membrane of the natural lens capsule, is the most common complication during cataract surgery, with its rate ranging from 0.5% to 5.2%. [2] In most cases the situation can be salvaged, though it may be necessary to modify the original plans for the placement, refractive strength, and type of ...
Posterior capsular rupture, a tear in the posterior capsule of the natural lens, is the most-common complication during cataract surgery. [8] Posterior capsule rupture can cause lens fragments to be retained, corneal oedema, and cystoid macular oedema; it is also associated with increased risk of endophthalmitis and retinal detachment.
Phacoemulsification is a cataract surgery method in which the internal lens of the eye which has developed a cataract is emulsified with the tip of an ultrasonic handpiece and aspirated from the eye. Aspirated fluids are replaced with irrigation of balanced salt solution to maintain the volume of the anterior chamber during the procedure.
Intraocular lens. 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 short sightedness and long sightedness; a form of refractive surgery. If the natural lens is left in the eye, the IOL is known as phakic, otherwise it is a pseudophakic lens (or ...
Cataract surgery was first mentioned in the Babylonian code of Hammurabi 1750 BCE. [12] The earliest known depiction of cataract surgery is on a statue from the Fifth Dynasty of Egypt (2467–2457 BCE ). [12] According to Francisco J Ascaso et al, a "relief painting from tomb number TT 217 in a worker settlement in Deir el-Medina " shows "the ...
A posterior vitreous detachment ( PVD) is a condition of the eye in which the vitreous membrane separates from the retina. [ 1] It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata ). The condition is common for older adults; over 75% ...
13.19. MeSH. D002387. [ edit on Wikidata] Capsulotomy (BrE /kæpsjuː'lɒtəmi/, AmE /kæpsuː'lɑːtəmi/) [1] is a type of eye surgery in which an incision is made into the capsule of the crystalline lens of the eye. In modern cataract operations, the lens capsule is usually not removed. The most common forms of cataract surgery remove nearly ...
