If cataracts already affect walking, get an ophthalmology workup for surgery; if both eyes are affected, do not delay the second eye too long

In women aged 70+, having first-eye cataract surgery sooner cut falls over the next year by about 34%; fewer people fractured bones. The number who fell at least once did not drop. Second-eye surgery showed no clear fall difference. Operated patients had about 16% lower hip fracture over one year.

Cost

Accompany the elder to ophthalmology once; the doctor decides whether to operate. One eye per surgery; many hospitals do day surgery and discharge the same day. If both eyes have cataracts, operate in two separate procedures. Out-of-pocket cost depends on intraocular lens (IOL) choice and local basic medical insurance (医保) reimbursement—ask before surgery.

Benefit

Randomized trial of 306 women aged 70+ with cataracts. Half had first-eye surgery within about 4 weeks; half waited 12 months per usual care. Over one year, early surgery cut fall counts by about 34%. Rate ratio 0.66, 95% CI 0.45 to 0.96. At least one fall: surgery group 49%, wait group 45%—no reduction. Two or more falls: surgery 18%, wait 25%. Fractures: surgery group 4 (3%), wait group 12 (8%). Cochrane included this trial: first-eye surgery in women reduced fall counts; second-eye surgery did not. Second-eye randomized trial, 239 women aged 70+: surgery group fall rate 32% lower but difference may be chance (rate ratio 0.68, 95% CI 0.39 to 1.19). U.S. Medicare 5% sample: 1,113,640 cataract patients aged 65+ (2002–2009), observational only. Surgery associated with about 16% lower one-year hip fracture odds (OR 0.84, 95% CI 0.81 to 0.87). Absolute difference 0.20 percentage points—about 2 fewer cases per 1,000 people.

Notes

Controversy: pooled across two randomized trials, the number who fell at least once did not fall significantly (OR 0.81, 95% CI 0.55 to 1.17). Western Australia all-population hospital records: in the year after first-eye surgery, fall-injury admissions rose 27%; between the two surgeries such admissions were 2.14× the pre-surgery rate. Before–after designs cannot separate surgery from aging. Another Australian cohort found fall counts dropped most after second-eye surgery—so if both eyes have cataracts, do not delay the second eye too long. Between the two surgeries, be extra careful walking and on stairs. Cochrane also included a vision-intervention trial where fall counts rose about 57%. Surgery fixes clarity; fewer falls still need Section 1 entry 13 (balance and leg strength). Whether bones survive a fall: Section 1 entry 39 (bone density testing) and entry 40 (treat osteoporosis if found). National eye health planning states cataract restoration surgery is widely available at county level—not only big-city hospitals. Main beneficiaries: your parents and grandparents.
