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]
The perception of floaters, which may be annoying or problematic to some people, is known as myodesopsia, [5] or, less commonly, as myodaeopsia, myiodeopsia, or myiodesopsia. It is not often treated, except in severe cases, where vitrectomy (surgery), laser vitreolysis, and medication may be effective.
After being used regularly for centuries, couching has been mostly abandoned in favour of more effective techniques, due to its generally poor outcomes, and is currently only routinely practised in remote areas of developing countries. [11] [12] Cataract surgery was first mentioned in the Babylonian code of Hammurabi 1750 BCE. [13]
Floaters suddenly appearing in the field of vision or a sudden increase in the number of floaters. Floaters may resemble cobwebs, specks of dust, or shapes such as ovals or circles; Flashes of light in vision ; Experiencing a "dark curtain" or shadow moving from the peripheral vision toward the central vision; Sudden blurred vision
The literature recognizes pseudoexfoliation syndrome as a risk factor in cataract surgery. A review based on 999 eyes with pseudoexfoliation reported 156 intra- or postoperative incidents. The identified predictive factors were a shallow anterior chamber, cataract grade, neutrophil-to-lymphocyte ratio, preoperative intraocular pressure, and ...
Access to cataract surgery is very variable by country and region. Even in developed countries availability may vary significantly between rural and more densely populated areas. Cataract surgery is the removal of the natural lens of the eye that has developed a cataract, an opaque or cloudy area. [1]
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.
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 ...
