LASIK vs. PRK

lasik or prk

If you have been told you are not a good candidate for LASIK because your corneas are too thin, you may not have to abandon your dream of 20/20 vision.

PRK (photorefractive keratectomy) is a type of laser surgery in Charleston that can produce similar vision results to LASIK vision correction, and it can be performed on some patients with thin corneas.

The difference between LASIK and PRK is in the first step of the refractive surgery procedure.
  • LASIK: A hinged corneal flap is created to allow access to the underlying corneal tissue for laser treatment
  • PRK: the cornea’s outer layer (epithelial) is gently removed to allow access to the underlying corneal tissue for laser treatment
The laser refractive treatment is the same for both LASIK and PRK: the cornea is slightly reshaped to correct the refractive error and allow light to focus on the retina for clear vision. Each laser treatment can be completely customized to your unique eye.

After the laser procedure, the corneal flap is repositioned during LASIK; after PRK, the epithelial cells need time to regenerate over the eye. Recovery and final vision results for PRK will take longer and the healing process may be slightly more uncomfortable. However, there is no risk of corneal flap complications with PRK.

Take the first step in the LASIK process: take the free online LASIK Self-Evaluation on charlestoncornea.com.

Prepare Your Eyes for a Special Event



Weddings…reunions…barbecues…vacations…

Special events abound during the spring and summer months. Many people take measures to look their very best for special events – they go to the hairdresser, buy new clothing, maybe even lose weight. If you have a special event coming up, and don’t want to have to hassle with glasses or contacts, you may choose to add LASIK to your To Do list.

The good news is that most people can be back to their normal activities – and seeing with more clarity – the day after their LASIK procedure. It is advised that you not wait until the last minute to schedule your appointment. Some people simply aren’t good candidates for LASIK because of their overall eye health, the fact that their corneas are too thin or other health reasons.  It’s important to schedule a LASIK evaluation well in advance of your special event just in case a different type of vision correction procedure like PRK is warranted. Some LASIK alternative procedures require more recovery time even though they can provide similar vision outcomes overall.

LASIK is an investment in you. The procedure has helped millions of Americans have the visual freedom to live a lens-free life. Find out if LASIK can give you the same freedom.

Get your eyesight in tip-top shape for your next special event. Contact Charleston Cornea and Refractive Surgery to schedule a free LASIK Consultation at 843-856-5275 or charlestoncornea.com.

LASIK and Astigmatism

Astigmatism is a common refractive error, which means that the eye does not focus light properly on the retina (the back of the eye). This condition causes light to focus on areas in front of and/or behind the retina, making vision blurry or distorted at all distances.

Astigmatism occurs when you have an irregularly-shaped cornea. LASIK vision correction can often correct the “football” shaped cornea of astigmatism into more of a “basketball” shape, thereby allowing light to properly focus on the retina and provide clear vision.

LASIK is not the best option for all patients with astigmatism. For example, if your corneas are too thin to support the procedure or if you have a medical condition that may interfere with healing, an alternative to LASIK (such as PRK) might be more appropriate.

Advances in LASIK technology have made this popular procedure a viable option for more patients than ever before. To find out if you might be a good candidate for LASIK, contact Charleston Cornea & Refractive Surgery in Charleston to schedule your free LASIK Consultation at 843-856-5275 or charlestoncornea.com

Common Consultation Questions – Part 3


For the past couple of weeks, we have addressed some of the most common questions asked by different patients about LASIK. Here are a few more.

How old do you have to be to have your vision corrected, either by LASIK or another laser vision correction procedure?

The rule of thumb on this question is 18. Your eyes are like any other organ in your body. They grow and develop as you age. The most important thing is for your eyesight to be stable prior to having LASIK. If a LASIK surgeon corrects your cornea and your vision hasn’t stabilized, they run the risk of under- or over-correction. You wouldn’t be happy with your results and most experienced LASIK surgeons won’t take that chance.

Isn’t it just safer to wear my glasses/contact lenses?
 
The truth to this question may come as a surprise. While contacts or glasses may be a viable option for many patients, the longer you wear them, the more likely you are to experience complications.

Complications of glasses or contacts include contracting bacterial infections, dry eyes from long exposure, or even trauma caused from an accident. Some patients may wear contacts or glasses for decades and never experience an issue. However, keep your contacts in your eyes for too long (or sleep in them) and you can instantly understand the issues these devices can cause.

This isn’t to say that LASIK isn’t without its risks as well. You can experience dry eye after LASIK. While the majority of patients overcome this side-effect quickly, some patients may need prescription eye drops to solve it.

The true question is not one of safety, but rather what you are willing to do to see clearly. LASIK can provide clear eyesight for many years to come, without the continual expense of lenses, solutions, etc.

We’d love the opportunity to discuss the possibility of life without lenses with you. Please feel free to call our office at 843.856.5275 with anymore questions, check out our website, or schedule a Free LASIK Consultation.

Common Consultation Questions – Part 2


Last week we addressed some of the most common questions asked by different patients about LASIK. Here are a few more.

Can I have LASIK while I am pregnant?

The answer to this question is no. When you are pregnant, your body goes through many changes. One of these changes can be your eyesight. These changes can throw off our exam results. We pride ourselves on superior results for our patients; therefore, we will not perform laser vision correction on any woman who is pregnant. After birth, we may ask a patient to wait from six months to a year for their vision to stabilize again before correcting their vision.

There are people, even famous people, speaking out against having LASIK because they had a not-so-great experience. Why?

There is always something important to be learned from others’ mistakes. This is one. LASIK is not for everyone. Even so, some surgeons will perform LASIK on anyone who wishes to have the procedure. This is a BAD IDEA.

If you perform LASIK on patients who are not optimal candidates, their sight may be negatively affected with the outcome. At Charleston Cornea and Refractive Surgery, we won’t take this risk. We will first ensure you are a candidate. If you are not, we will explain why and also let you know if there is anything we can do (i.e. another procedure) to help you see clearly.

This practice of performing LASIK on everyone who walks in the door is more common in a corporate-owned LASIK office. Corporate offices are more concerned with their income, thus they’ll opt to do as many LASIK procedures as possible, even at risk to the patient's results.

We will continue this discussion next week. If you are seeking answers immediately, please feel free to call our office at 843.856.5275, check out our website, or schedule a Free LASIK Consultation.

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.

First, let’s look at the benefits of a laser vision correction procedure, like LASIK or PRK:

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. 

“I’d worn corrective lenses of some type for 48 years and words fail me to describe how good it was to wake up the first morning and see the clock!” 
– Tommy Rutledge

“After nearly fifteen years of not being able to see without lenses, I decided to have LASIK surgery. It has changed my life. I see clearer than I ever did with glasses or contacts. If I had to make the choice again, I would without a doubt choose to have LASIK by Dr. O’Day at Charleston Cornea and Refractive Surgery.”
- Tina Campbell

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.

LASIK versus 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.
