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. This effect is temporary as the brain and eyes gradually adapt to the ...
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Visual outcome after cataract surgery was close to conformity with WHO guidelines in Buenos Aires, where more than 80% of post-surgery eyes had visual acuity of 6/18 (20/60) or better, but ranged between 60% and 79% in most of the other regions, and was less than 60% in Guatemala and Peru. [129]
After surgery, doctors will send you home with an eye cover, and you’ll return for a follow-up appointment the next day. Because of the eye patch and sedation, patients will need to arrange for ...
Changes in the eye can help predict other health concerns in the body, such as diabetes and high blood pressure. A new study has identified a set of 29 vascular health indicators on the retina ...
Visual or vision impairment (VI or VIP) is the partial or total inability of visual perception.In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

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.
Neovascularization of the eye, often associated with diabetes mellitus, is also a risk factor. People who have undergone surgery (such as for cataracts) may develop hyphema during or up to a week after the surgery. [9] Vitreous hemorrhage can be caused by proliferative diabetic retinopathy, vitreous detachment with or without retinal breaks ...
