LASIK vs PRK
Refractive errors occur when the cornea of your eye, or the front part of your eye, is misshaped. These refractive errors produce nearsightedness, farsightedness, or astigmatism. Laser vision correction is the procedure through which a laser is used to reshape the cornea of the eye, in order to achieve better vision.
While the actual correction of the cornea is completed with a laser, the steps leading up to this correction, and subsequently the healing after, will differ depending on the specific procedure the surgeon chooses for the patients’ eyes. The two main procedures most commonly used are LASIK (Laser-Assisted Sin-Situ-Keratomileusis) or PRK (Photorefractive Keratectomy).
LASIK and PRK
Most people have heard of LASIK; however, in some cases, LASIK isn’t the best procedure for them. This can be due to a multitude of reasons, but most often if their cornea is too thin, LASIK will not be advised. This is why visiting an ophthalmologist that performs more than just LASIK is so important. Other procedures, such as PRK, can be recommended and performed to achieve the same, and sometimes even better, results.
The main difference between LASIK and PRK comes during the first step of the process – creating the corneal flap. During LASIK, the surgeon creates flap within the first few layers of the outer surface of the cornea, so that the laser can reach the area that needs to be corrected. This can be done with a microkeratome (a mechanical oscillating blade), or during bladeless LASIK, it can be done with a second laser that separates the outer layer of the cornea. After the primary laser is applied to correct the refractive error, this flap is folded back into place where it bonds readily.
PRK, which is usually performed on patients with thin corneas, removes the surface layer of cells on the cornea. This is why it is often referred to as a surface treatment. After treatment, the body will regenerate new cells to replace the cells removed through a relatively quick healing process. The results of PRK are equal to that of LASIK though the healing times are slightly longer.
Visiting a Qualified Ophthalmologist
Performing LASIK on a patient that is better suited for a procedure like PRK will increase the likelihood of potential risks, such as poor night vision or less than optimal results. To decrease these risks, visit a board-certified ophthalmologist who is skilled at multiple vision correction procedures. This will ensure you the best possible chances to achieve the vision results you are seeking. Visit us at www.eyeclinic2020.com for more information.

Fears and Misconceptions of LASIK – Is the Price Worth it in the Long Run?
We have personally seen many different types of people come
through our Free LASIK Consultation. Some people question technology, some
concern themselves with safety, and many are concerned that the cost of the
procedure may not outweigh the benefits. Since our website deals largely with
the issues of technology and safety, let’s address the issue of cost versus
benefits.
It is possible for a patient to achieve 20/20 eyesight, or even
better, with laser vision correction. You could live your life waking up and
seeing immediately instead of searching for your glasses. You can experience
the spontaneity of life, such as jumping in a swimming pool, playing in the
rain, or going out on a windy day, without the fear of how any of these actions
may affect your contacts and your ability to see. You can take a nap, free from
the worry of taking your contacts out of your eyes first. You don’t have to
rush to the store every time you are out of contact lens solution or order more
glasses when yours accidentally break. You will be able to see life, naturally.
Is all that worth the cost of LASIK?
Our patients think so.
"As someone who has worn glasses/contacts for over 12
years, I can honestly say that the LASIK procedure completely changed my life!
Waking up in the morning and being able to see the clock without having to
squint or put on my glasses was incredible to me. If you are thinking about
having LASIK, I totally recommend it, it is so worth it! The staff at the Eye
Clinic of Austin are so great and they really make you feel at ease."
- Lauren S.
However, some people have heard that people who have had LASIK
eventually return to wearing glasses. How can this be if they have already had
their vision corrected?
Let’s clear up one fact – LASIK or laser vision correction will
NOT give you excellent vision for your whole
lifetime.
Wait – what?
It’s true. Your eyes are living organs and there are certain,
inevitable conditions that occur due to aging. One of these conditions is known
as Presbyopia. Presbyopia is when the natural lenses in your eyes begin to
harden. When you are young, your lenses are flexible so they can adjust to
seeing near and far. As you age, these lenses harden. When they lose their
flexibility, bifocals or reading glasses are used to help your eyes adjust.
Another inevitable is cataracts. Everyone will develop cataracts
as they age. The affect that a cataract has on your vision depends largely upon
the degree to which they form. Some people will never notice the affect while
others may go blind.
The age at which you develop cataracts and/or presbyopia is not
predetermined. For some, the symptoms of presbyopia can begin appearing as
early as 40. For others, they may not have any side effects until 50 or older.
For cataracts, most don’t appear until your early 60s or even into your 70s.
So back to the question – is the cost of LASIK worth it in the
long run?
Let’s say you are nearsighted and you purchase disposable contact
lenses every month. Then you have to purchase cleaning solution each month. If
you lose a contact, tear it, it falls out, etc., then you have to replace your
monthly supply faster than anticipated. You also have to get a pair of glasses
for the times you don’t have contacts or if you have an eye infection or you’ve
worn your contacts for too long. These glasses can easily be lost or broken, so
it’s not just a one-time expense.
This is a cost you have to pay, every month, consistently for 20
or more years. You are stuck with plastic on your eyes and the constraints they
present just so you don’t have to compromise the ability to see.
Or you can have laser vision correction and have your procedure
paid off in two years or less. You'll gain the extra money in your budget and
excellent eyesight to view life as it is. You’ll also gain the spontaneity that
life has to offer because you can see clearly, naturally.
