Once the laser eye surgery is completed successfully, the changes made over the cornea become completely stable and permanent. The new vision will be quickly adapted by the eyes. This improved vision continues for very long period and after you get older, this vision may get influenced because of the aging process.
Eyesight After Laser Eye Surgery
Technically, yes, it is possible that the eye sight may become worsen, either after shorter period of time or longer period of time, post the surgery. It is purely because of the aging process of the human body, not at all because of the laser eye surgery. In case the laser eye surgery is not successful, improper vision may result, but is immediate, rather than after a couple of months or years. Though smaller vision problems occur, immediately after the surgery, these discomforts are quite temporary and never last long, unless in cases of intense complications or infections. So, it is worth noting by you that the worsening of the eye sight is not at all because of the laser surgery, but because of the aging process.
Aging Process and Vision Problems
Aging process is continuous and it starts right after the birth. However, the degradation of the function of each of the body parts start usually after 40s. Eventually, hard parts become softer and soft parts become harder with aging. The same happens with the eyes and the changes in the eye and eyesight and this condition is called Presbyopia, which starts at 40s and continue for the rest of the life.
Eyesight Assurance After Laser Eye Surgery
No eye doctor or no laser medical centre assures you of removing the need for the glasses for life long, not because of the unsuccessful predicted outcomes, but because of the natural changes of the eye which may need eye glasses in the future, even after getting older.
Most of the laser medical centres give assurance that the laser eye surgery can be successful and the outcomes can reduce or remove dependency over the eye glasses or contact lens. They assure for better eye vision, because of the trust they have on the advanced laser technology. In case the outcomes are not at the optimum level, they can easily make further corrections through enhancement procedure.
So, technically, there are pure chances that the patient can get rid of hassle-some eye glasses or contact lens after the laser eye surgery or may need them after a period of time, after you grow older, as the eyesight may get worse with your age.
