Laser Vision Correction 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 laser vision correction; however, in some cases, laser vision correction 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, laser vision correction will not be advised. This is why visiting an ophthalmologist that performs more than just laser vision correction 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 laser vision correction, 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 laser vision correction, 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 laser vision correction though the healing times are slightly longer.
Visiting a Qualified Ophthalmologist
Performing laser vision correction 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.

Why Your Eye Surgeon Needs to be Local

Corporate medicine has its benefits and its downfalls. In regards to the refractive surgery field, there are more downfalls to a corporate practice than there are benefits. But first, let’s take a look at what the difference is between a local ophthalmology practice and a corporate one.

Local Ophthalmology Practice

A local ophthalmology practice is one that has one or just a few locations, all found within the same state, the same geographical region. The doctors and staff are all from the area as well.

Local practices are usually owned by the doctor or surgeon, or a small group of doctors or surgeons. They are responsible for all of the decisions regarding staffing, technology, services offered, and everything else that is included with their particular practice.

Corporate-Owned Ophthalmology Practice

A corporate-owned ophthalmology practice is one that has multiple locations, usually nationwide. These practices are run through a company, which is run by a board of directors. They often only offer one or two services, usually just LASIK, and maybe PRK. They employ thousands of doctors and traditionally these doctors work at multiple locations. They travel to different locations, perform surgery and then travel to another location. Some doctors even travel to different states just to perform surgeries.

All decisions are made by a board of directors, not the staff or doctors working in each particular location.

The Difference

So what’s the difference? Why should you choose one location over the other?

Doctor Availability

Perhaps the biggest factor in why you should really know the difference between the two types of ophthalmology practices is doctor availability. In a locally owned practice, the doctor lives in or near town. S/he works at the practice full-time and performs consultations, the planning of treatment, the surgery, and the post-operative follow-up exams on each patient that comes through the door. They have a relationship with their patients, and they are most likely there for anything the patient may need.

In a corporate practice, the doctor sees patients at multiple locations. S/he will fly in, review the chart and work-up of the patient without even meeting or personally examining the patient, perform the surgery, and then fly off. This means that the surgeon that performs your particular surgery is not available for pre-surgery exams, follow-up, or even during emergency-related issues that may have resulted from your surgery. They usually have an optometrist perform these tasks. An optometrist, while a perfectly capable doctor, is not trained in the actual performance of the surgery. If a complication arises that the optometrist is not qualified to respond to, where are you going to go? Who’s going to help?

Sometimes an optometrist refers a patient for laser vision correction When this happens, the laser vision correction surgeon will perform the surgery and then refer you back to your optometrist for follow-up exams. This works well when you are referred to a local practice, so that your surgeon will still be available for any emergency issues that may arise.

So which would you prefer – a surgeon operating on your eyes, someone you’ve never met, who’s never actually seen your eyes and who won’t be around if you have an emergency? Or would you rather have someone who is local, available throughout the week, and who takes it as a personal responsibility to care for you and your eyesight?

Putting in Your Contacts with Your Feet?

We don't often write about other laser vision correction practices, but this story highlights one practice doing what it knows to help others in the community, specifically Jessica Cox of Overland Park, KS.

Jessica Cox does not have any arms and currently does everything with her feet. This includes putting in her contacts every morning!

Now, through the gift of laser vision correction, Jessica will be able to take that routine out of her life. We applaud Dr. Daniel Durrie for helping this young lady and giving her one less challenge in her life.
