What do early stage cataracts look like?

How much diabetes is normal for cataract surgery?
Joint British Diabetes Societies Guidelines20 and American Diabetic Association38 recommend that blood glucose concentrations should be maintained between 140–180 mg dL?1 (7.8–10.0 mmol L?1) during the perioperative period.
