The initial treatment of cataracts is mainly conservative and based on medication, but the treatment effect is not exact. Cataracts are a progressive, painless loss of vision due to clouding of the lens that affects retinal imaging. Initial cataract patients can follow the doctor’s instructions to use eye drops to ease the progression of cataracts, such as beryllocaine eye drops, bendazac lysine eye drops and so on. At the same time, patients can also assist with medications for nutrition, such as vitamin E and vitamin C. With the development of cataract, patients should take cataract surgery, such as ultrasonic emulsification cataract with IOL implantation, so as to improve vision. Cataract patients are advised to visit hospitals in time to assess their condition and under the guidance of doctors.
