Most complications of cataract surgery do not result in long-term visual impairment, but some severe complications can lead to irreversible blindness. [92] A survey of adverse results affecting Medicare patients recorded between 2004 and 2006 showed an average rate of 0.5% for one or more severe post-operative complications, with the rate ...
Unlike traditional cataract surgery, which relies on manual incisions and ultrasonic tools, laser cataract surgery uses high-tech laser systems to perform many steps of the procedure, says Dello ...
Complications after cataract surgery are relatively uncommon. Posterior vitreous detachment (PVD) may occur but does not directly threaten vision. [23] Some people develop a posterior capsular opacification (PCO), also called an after-cataract. This may compromise visual acuity, and can usually be safely and painlessly corrected using a laser.
Pupil dilation typically begins within 15 minutes and may last for 3–8 hours. [6] [7] After the pupil has been dilated, an ophthalmoscope can be used to examine the fundus. This allows for 15x magnification of the optic disc, also known as the optic nerve head, and retina to better evaluate for any ophthalmic pathology. [9]
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 ...
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]

Macular edema sometimes occurs for a few days or weeks (sometimes even much longer) after cataract surgery, but most such cases can be successfully treated with NSAID or cortisone eye drops. Prophylactic use of Nonsteroidal anti-inflammatory drugs has been reported to reduce the risk of macular edema to some extent. [10]
