Should diabetics get cataract surgery?
Cataract surgery is a common and safe procedure, but can be associated with vision-threatening complications in the diabetic population, such as diabetic macular edema, postoperative macular edema, diabetic retinopathy progression, and posterior capsular opacification.
Does cataract surgery make diabetic retinopathy worse?
When is it too late for cataract surgery?
Although it’s never too late to have a cataract removed, it is better to have cataracts removed while they are immature, as this reduces the length of surgery and the recovery time.
