The procedure is performed once in a lifetime. The key to achieving the best result is a thorough qualification process and the stability of the vision defect. During the preliminary qualifying examination, the ophthalmic surgeon selects the optimal correction for the patient. Just before the procedure, the data obtained during the examination, such as corneal thickness and shape, as well as the severity of the refractive error, are entered into the laser. This means that the specific correction is applied permanently to the eye.
In every person, around the age of 40-45, presbyopia starts to develop. It manifests itself through difficulty seeing objects up close—making it harder to read a newspaper or text on a phone or computer. This is a natural, progressive physiological process and has no relation to laser vision correction. Additionally, laser vision correction does not prevent the need for reading glasses associated with age.
The outcome of the procedure will vary for each patient, even if they share the same vision defect or correction method applied. Factors such as the individual’s unique characteristics and adherence to the ophthalmic surgeon’s recommendations also play a role. The durability of the result later in life is influenced by factors such as chronic diseases, lifestyle, long-term use of medications, or pregnancy. The same applies if eye diseases, typically age-related, such as macular degeneration, glaucoma, or cataracts, are diagnosed. These are factors that affect vision deterioration, regardless of whether the patient has undergone the laser vision correction procedure or not.
