A laser vision correction surgery reshapes the surface of the very thin corneal layer and does not affect the intraocular lens, which is responsible for reading vision. Presbyopia develops naturally in everyone over 40-45 as a result of the loss of the lens elasticity. Laser remodelling of the corneal surface allows to correct short-sightedness, astigmatism and far-sightedness, i.e. refractive errors developed during the adolescence period, when the visual system was still not fully formed. Presbyopia is not a refractive error but a natural physiological process resulting from ageing, like wrinkles and grey hair. This process gradually progresses, which means you will need stronger and stronger reading glasses.
