The Benefits of Laser Eye Surgery
Those suffering from myopia, hypermetropia and astigmatism can
benefit greatly from LASIK or the PKR laser eye surgery. LASIK can
benefit the patient by removing the need for corrective lenses for
seeing far off objects. The same is true of those who struggle with
seeing close by objects.
Those with hypermetropia presbyopes are good candidates for refractive
laser surgery because in addition to an improvement in the distant
vision, they have a partial recovery of the near vision and can often
read a menu card, or see the hole in a needle without correction.
LASIK and PKR are aimed at improving the uncorrected vision, i.e. vision
without corrective lenses for most patients undergoing the process. More
than 90% of patients with low or moderate myopia reach 8 / 10, vision
regarded as sufficient for driving without contact lenses or eyeglasses.
Many patients can expect a 10/10 vision or better, however, there is no
guarantee that perfect vision will be achieved. In addition, in cases of
pronounced myopia or hyperopia (respectively above-8D and +4 D),
expectations should be more moderate. Those most satisfied with the
results of a laser correction are those who have understood and measured
the potential risks and possible complications of surgery and have
realistic expectations about their postoperative vision.
The effects of refractive surgery are permanent and does not
dissipate with time. It is important to remember that certain eye
features of a person can always change with time. Also, many surgeons
recommend proceeding with the intervention after the eye has acquired a
stable form. Thus, surgery is not recommended for children because their
eyes change a lot with growth and that their vision should then be
adjusted again a few years later.
If the process is made after age 18, the chances of correction being
stable and long term are higher. However, even the eyes of a patient
over 18 years can still change. Accordingly, the surgeon will evaluate
the changes that have occurred in deciding whether to wait for their
slowdown. The patient must also note that if the results are usually
stable, they can be modified by other processes to be made later if
needed.
The scar phenomena are exacerbated in some patients and can cause a
"regression" of the effect of surgery in the weeks following the
surgery. If the patient's vision changes after refractive surgery, the
process can possibly be resumed. The recovery may be a viable solution
to the changes that may occur later, but other treatment options exist.
The patient should consult their ophthalmologist to determine the
appropriate option. The realization of a recovery operation is generally
free in the year following the initial intervention. |
