Replacement of the lens as treatment for cataract can cause pseudophakic macular edema ('pseudophakia' means 'replacement lens'), also known as Irvine–Gass syndrome. The surgery involved sometimes irritates the retina (and other parts of the eye) causing the capillaries in the retina to dilate and leak fluid into the retina.
Epiretinal membrane or macular pucker is a disease of the eye in response to changes in the vitreous humor or more rarely, diabetes.Sometimes, as a result of immune system response to protect the retina, cells converge in the macular area as the vitreous ages and pulls away in posterior vitreous detachment (PVD).
After cataract surgery, patients with diabetes mellitus are generally acknowledged to have an increased risk of macular edema. [12] A prior history of retinal vein occlusion was the only significant preoperative risk factor in a large retrospective series of 1659 consecutive cataract surgeries. [13]
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'.
Cataract in human eye . Post-Cataract Surgery: After cataract surgery, the natural lens, which filters blue light, is replaced with a synthetic lens that allows more blue light to pass through. This sudden increase in blue light reaching the retina causes the brain to perceive a blue tint in vision.
Sheep eye lens capsule with ligaments attached. The capsule is lifting off the lens showing cell fiber ends beneath. Microscope image of lens capsule in relation to lens cell types. The lens capsule is a component of the globe of the eye. [1] It is a clear elastic basement membrane similar in
Bruch's membrane thickens with age, slowing the transport of metabolites. This may lead to the formation of drusen in age-related macular degeneration. [4] There is also a buildup of deposits (Basal Linear Deposits or BLinD and Basal Lamellar Deposits BLamD) on and within the membrane, primarily consisting of phospholipids.
Complications after cataract surgery are relatively uncommon. Posterior vitreous detachment (PVD) does not directly threaten vision, but may increase the risk of future vitreoretinal conditions. It may be more problematic in younger eyes because many people older than 60 have already gone through PVD.
