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.
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 surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [4] [10] Cataracts usually develop slowly and can affect one or both eyes. [4]
Intraoperative floppy iris syndrome (IFIS) is a complication that may occur during cataract extraction in certain patients. This syndrome is characterized by a flaccid iris which billows in response to ordinary intraocular fluid currents, a propensity for this floppy iris to prolapse towards the area of cataract extraction during surgery, and progressive intraoperative pupil constriction ...
Modern cataract surgery is one of the safest and most effective surgical procedures, says Dello Russo, with a 98% success rate. “Many people report that they wish they hadn’t waited so long to ...
Before surgery (natural crystalline lens, left). After surgery (implanted PCIOL, right). An anterior chamber IOL (ACIOL) Posterior chamber IOL (PCIOL). This is by far the most common type of implanted lens after cataract surgery, as this is the natural and optimum position for a lens. [citation needed] Anterior chamber IOL (ACIOL). A less ...
The primary causes include post-cataract surgery, certain medications, and, less commonly, neurological or ophthalmological conditions. Post-cataract surgery is a common cause, as replacing the natural lens with a synthetic one increases exposure to blue light, leading to temporary blue-tinted vision. This effect usually resolves as the eye adapts.
Iridodialyses are usually caused by blunt trauma to the eye, [2] but may also be caused by penetrating eye injuries. [7] An iridodialysis may be an iatrogenic complication of any intraocular surgery [10] [11] [12] and at one time they were created intentionally as part of intracapsular cataract extraction. [13]
