A recent study showed that cataract surgery helps prevent hip fractures. It looked at a sample of Medicare patients with cataracts who did or did not have cataract surgery. Those who had cataract surgery had a 16% less change of subsequent hip fractures than those who did not have the surgery, though the absolute difference between the groups was small, because hip fractures were not that common in either group.
The design of this study was not optimal. It would have been better to randomly assign patients to get cataract surgery or not, to eliminate possible biases, but such a study is not practical.
We treat osteoporosis with medications such as Fosamax (alendronate) and vitamin D, but that just decreases the risk of a fracture. It’s still important to prevent the fall. There are various things that can help, including physical therapy to improve gait (walking), good lighting, good shoes, lack of loose rugs, canes, and more. Add to the list cataract surgery for those affected. Not only will such patients improve their vision, but they may save themselves from a hip fracture that at best will lay them up for a while, and at worst kill them from complications of pneumonia or a deep venous thrombosis (DVT or blood clot) and pulmonary embolism (blood clot to the lungs).
