Laser for presbyopia is not reliable. Presbyopia, also called old vision, is a normal physiological state. With age, the lens gradually hardens and becomes less elastic, and a series of symptoms may appear, such as difficulty in seeing near, the need for stronger illumination when reading, the inability to see near objects for long periods of time, blurred vision, and so on. Presbyopia can be corrected in three ways, such as wearing framed glasses, corneal contact lenses, and refractive surgery. Generally it is not recommended to treat presbyopia through laser, because presbyopia is of the lens and the regulation ability decreases, which leads to the fact that the purpose of treating presbyopia cannot be achieved through laser surgery, so laser treatment of presbyopia is not reliable. Presbyopia is a normal physiological phenomenon, patients may have symptoms of blurred vision, if necessary, go to the hospital ophthalmology, can be corrected by wearing glasses or surgery and other ways.
