What is Refractive Surgery?
Becoming
independent from eyeglasses and contact lens are a
rather common dream among people who possess some
kind of eye disorders, such as myopia, astigmatism
and hyperopia. These disorders, called ocular refractive,
can be corrected – in most cases – by
a surgical procedure: refractive surgery.
Obtaining
freedom to practice physical activities or being able
to go out at night, driving and reading without aid
is absolutely possible to most people.
Besides
the comfort of nod depending on any accessory, refractive
surgery also makes possible the interruption of frequent
expenses with new contact lens and eyeglasses.
Why submit myself to Refractive Surgery?
The
procedure is indicated to the absolute majority of
cases with refraction errors, such as myopia, hyperopia
and presbyopia. However, to perform the surgery is
necessary for the patient detailed exams for the patient,
since those will determine what should be indicated
and what are the expected results.
It
is fundamental for a patient to wish to be free of
eyeglasses with safety, find a medical facility ready
to answer any questions the patient may have. At the
Hospital de Olhos, the evaluation performed before
surgery is done by experienced professionals at the
same day, which allows more comfort and commodity
for the patients.
How is the Refractive Surgery done?
The
Refractive Surgery techniques are known for many years,
and today are in a definite stage of improvement.
Those procedures are executed in few minutes, without
the need to intern the patient, which permits the
patient to return to his routine the following day.
The
Refractive Surgery techniques who obtain safer and
better results are: - Photorefractive keratectomy (PRK)
- A type of refractive surgery which reshapes the
cornea by destroying microscopic amounts of tissue
from the outer surface with a cool, computer-controlled
ultraviolet beam of light (an excimer laser). - Laser Assisted In-Situ Keratomileusis (LASIK)
- The Refractive Surgery procedure most
performed in 2005. It is used for a wide range of
nearsightedness. The surgeon uses an instrument called
a microkeratome to cut a flap of corneal tissue, opens
the flap like a hinged door, removes the targeted
tissue in the corneal stroma beneath it with the excimer
laser, and then replaces the flap.

TESTIMONY
Carlos Frederico Silva Habel, 39
“Depois
de muitos anos com um alto grau de miopia, e altamente
dependente dos óculos e das lentes, descobri
a liberdade proporcionada pela correção
visual a laser. Hoje os óculos são coisa
do passado. Minha vida ficou muito mais ativa, sem
a barreira da visão. Piscina, praia, esportes.
Hoje aproveito muito mais cada um desses momentos(...)"
Customized Lasik
Personalized Vision Correction or Customized Lasik is a new laser treatment based on unique visual characteristics of each eye and is the most advanced procedure currently available.
Besides near-sightedness, far-sightedness, and astigmatism our eyes have other aberrations that are not correctable with glasses or contact lenses. These aberrations can affect the quality of vision, especially at night, and can be diagnosed and measured using a Wavefront map. The wavefront analyzer measures the way light travels through your eye and compares it to the way light travels through an eye with perfect vision. This device then creates a 3-D wavefront map that is unique. The results are sent to a computer program that gives you the best treatment for your specific problem.
The actual procedure takes only minutes to perform and is painless. Patients can usually see quite well immediately after the surgery and frequently resume normal activities within a short period of time.
Personalized Vision Correction is better than the usual Lasik surgery, if needed, because is customized, may improve not only what you see but also how well you see it, and gives you the best diagnoses and results for your unique eye.
Personalized vision correction takes more corneal tissue than the usual procedure, so doctors must be very careful on recommend it, avoiding unnecessary excessive ablation that might weak the cornea.
