Fortunately, modern forms of cataract surgery have a low risk of complications. Moreover, cost can be an issue, and people often need to continue wearing eyeglasses, even after the surgery. 29.

Furthermore, the general anesthesia techniques used in older studies assessing stress response do not correspond to current anesthesia techniques for cataract surgery which include use of supraglottic devices, maintenance of spontaneous breathing, opioid-sparing, minimal depth of anesthesia, and topical anesthesia as well. Other considerations include the ability of the patient to transfer themselves or the need for special lifting equipment to ensure patient and employee safety.

One study found only a significant association between low, not elevated, preoperative blood pressures and increased postoperative mortality in an elderly population of patients.2 POQI concluded that there was insufficient data that preoperative blood pressures should alter decisions to proceed with surgery or not, and there is insufficient evidence to support lowering blood pressure in the immediate preoperative period to lower perioperative risk.37 SAMBA recommends against acutely lowering blood pressures for patients anticipating cataract surgery immediately preoperatively. This damage allows fluid from other parts of the eye to rapidly enter the lens leading to swelling and then whitening, obstructing light from reaching the retina at the back of the eye.
