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]
Laser peripheral iridotomy may be done either before or following cataract surgery. [87] Swelling of the macula, the central part of the retina, results in macular oedema and can occur a few days or weeks after surgery. Most such cases can be successfully treated.
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.
Even after treatment, it can take months for the body to clear all of the blood from the vitreous. [2] In cases of vitreous hemorrhage due to detached retina, long-standing vitreous hemorrhage with a duration of more than 2–3 months, or cases associated with rubeosis iridis or glaucoma , a vitrectomy may be necessary to remove the standing ...
[1] [2] [8] [9] After surgery, the person is often positioned in a prone position to reduce the risk of hemorrhages by preventing blood from reaching the macula. [27] The band typically remains in place permanently unless complications occur. [8] During the procedure, subretinal fluid may also be drained, though it is sometimes left to reabsorb ...
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 ...
