Permanent vision loss is not an expected result of most nasal flap or reconstructive nasal surgeries, but no operation around the nose is completely risk-free. Very rare serious complications can involve bleeding around the eye, vascular compromise, infection, or an anesthesia-related event; these are uncommon, but they are the reason a careful preoperative assessment matters. At age 72, diabetes and overall cardiovascular and eye health should be reviewed before surgery. Ask the reconstructive surgeon exactly what type of flap and anesthesia are planned, how often they perform the procedure, and what precautions are used. A recent eye examination can document your baseline vision and address whether the need for readers is simply age-related near-vision change (presbyopia), which is common and not usually caused by nasal surgery. Good glucose control and a complete medication review are also important. If surgery has already occurred and there is sudden or worsening loss of vision, double vision, severe eye pain or swelling, a new visual field defect, marked headache, or new flashes/floaters, treat that as an emergency and contact the surgeon and an emergency eye service immediately.
