The general treatment for cataracts in 70 year olds includes medication and surgery, but the exact treatment is largely based on the patient’s needs. Geriatric cataract is a clouding of the lens in middle-aged and elderly patients, the prevalence of which increases significantly with age. The development of this disease is related to a variety of factors including environment, nutrition, metabolism and genetics. Early symptoms of cataract are usually not obvious, only mild blurring of vision. When the clouding of the lens worsens and the patient’s vision decreases significantly, the patient can be treated with medication or surgery. Medication is suitable for patients with mild symptoms who have not yet met the criteria for surgery, such as amiodarone peptide eye drops, which can control the progression of the disease, but cannot reverse the clouding of the lens. Surgery is the mainstay of cataract treatment, aiming to remove the already clouded lens and implant an artificial lens to improve the patient’s vision. Current cataract surgical treatment is mature and effective, with short operation time, small incision and quick recovery. It is recommended that cataract patients should consult a doctor in time to assess their condition and follow the doctor’s instructions to choose the appropriate treatment.
