Lasik Eye Treatment:

Welcome to Laser Eye Treatment

by Mathew in Laser Eye Treatment

Thank you for visiting the Laser Eye Treatment Guide. Our intention is to provide you with a comprehensive guide to the different types of laser eye treatment techniques currently available. There are many aspects involved when choosing which procedure is the right one for you. We plan to provide you with the information to help you decide for yourself, which is the best eye treatment center.

Laser eye treatment is most commonly associated with vision correction procedures to correct nearsightedness (myopia), farsightedness (hyperopia), astigmatism and the need for reading glasses (presbyopia). It is also used to treat diabetic retinopathy and detached retinas.

The three main laser vision treatment procedures available are Lasik, Lasek and PRK. They are all slightly different techniques and while none of them require an overnight hospital stay, their recovery times and the discomfort felt do vary.

Lasik (Laser in Situ Keratomileusis)

Lasik is the most popular type of laser eye surgery. A laser eye surgeon (ophthalmic surgeon) reshapes the cornea using a special laser known as an excimer laser. Lasik has the shortest recovery time compared to Lasek and PRK.

Lasek (Laser Epithelial Keratomileusis)

Lasek is a slightly different procedure to Lasik, in that a flap is cut from the protective tissue over the eye and not in the cornea beneath. Though Lasek has a slightly longer recovery time than Lasik, it can be used on patients with with unusually thin or flat corneas.

PRK (Photorefractive Keratectomy)

PRK was the first corrective vision procedure to use excimer lasers. With PRK an outer layer of cells from the surface of the cornea are removed, instead of a corneal flap. This lengthens the recovery time and discomfort felt after the procedure.

Suitability for Laser Eye Treatment

Not everyone will be suitable for laser eye treatment, which is why anyone wanting to undergo laser treatment to correct their vision will be given a thorough examination before any eye surgery will be performed. One alternative is implantable contact lenses. These are, as the name suggests, contact lenses that are permanently implanted into the cornea. The recovery time from this procedure may be longer than that of laser eye surgery, but unlike standard contact lenses do not require any maintenance.

Is Laser Eye Treatment Permanent?

by Mathew in Laser Eye Treatment

Laser eye treatment is permanent, but its effects are not. That one simple sentence sums up the hope and the frustration inherent in vision improvement surgeries. You go to the doctor to have your vision fixed, enjoy the benefits for a time, and then wake up one day noticing that the world has gone a bit fuzzy around the edges. What is going on?

Changes Over Time

For 9 out of 10 people, the problem has nothing to do with the laser eye treatment you paid for when you were in your 20’s or 30’s. The issue is with your eye. As the eye ages, it becomes less flexible, and this changes its abilities to refract light and give a clear picture of the world.

Laser eye treatments can address refractive imperfections caused by the shape of your eye. By reshaping the cornea, the clarity of your vision can be improved. The effects of this reshaping are permanent. A topographical map of your eye will show you the differences, and you will need to modify your ophthalmological screenings for glaucoma and cataracts as a result of your treatment.

However, the refractive analysis that your ophthalmologist did at the time of your surgery was designed to give you the best vision possible for the current state of your eyes for your age. As your eyes age, your refractive analysis may become less applicable to your vision. You will notice this as a gradual blurring, especially of distant objects, as distance vision goes first.

Preserving Your Vision

What can be done? At the moment, there is little that can be done to reverse the effects of aging of vision. LASIK surgery is very limited in its potential for touch ups, although PRK/LASEK offers more opportunity for follow-up work. However, like any cosmetic surgery, there reaches a point beyond which things are simply not going to get any better looking.

Glasses and contact solutions are good compensating options. Depending on the way your cornea healed after your surgery, you may not be able to wear just any brand of contact. Some contacts require certain curvatures to provide a good fit to your eye. Have a thorough discussion with your doctor about the best options for the health of your eye—laser eye treatments coupled with contacts can limit oxygen flow to your cornea, and you will want to ensure you continue to get enough oxygen to your eye to maximize your remaining vision.

Additionally, discuss with your eye doctor any supplements you may want to take to feed your eye as you age to keep your vision strong. There are a number of products on the market, but not all are effective. However, your doctor should be able to recommend a budget-friendly product that will help you get the best vision from your eyes as you continue to age.

Laser Eye Treatment Technologies

by Mathew in Laser Eye Treatment

There are actually many different technologies used for laser eye treatment, with new ones constantly being developed. There are essentially two steps to the procedure. First, the surgeon gains access to the cornea, which is the part of the eye that bends the light entering it, producing our vision.

Here are a few ways that the surgeon accomplishes this:

  • During LASIK eye surgery , the surgeon uses a tiny handheld blade to cut a flap in the surface of the eye.
  • IntraLase LASIK lasers use a computer-guided beam of light to create the access flap. It is more precise than the blade technique, so it heals better than traditional LASIK flaps.

  • LASEK eye surgery involves the lifting of the outer layer of your eye with a fine blade. Then, alcohol is used to loosen the tissue so that the laser can access the underlying cornea.
  • PRK eye surgery “vaporizes” the outer surface of the eye using a special laser. This method takes a little longer to heal than other laser eye treatment methods.

Once the surgeon can access the cornea, it is precisely reshaped to change your vision. Usually, this employs a computer-guided laser beam. Current technologies include:

  • Excimer lasers . These have been used since the early 1990’s. This type of laser uses light to vaporize a small amount of tissue from the center of the cornea. This is a cool beam of ultraviolet light, unlike other surgical lasers that burn tissue using heat, or produce a shock wave to separate the tissue. By vaporizing the tissue one layer at a time, the Excimer laser is very accurate for changing the shape of the cornea.
  • Wavefront Custom LASIK is an even more personalized form of vision correction, using Wavefront-guided lasers. This technique uses special lasers to measure eye irregularities on a 3D map, which then guides the computer in reshaping your cornea. This is much more accurate than traditional laser eye treatment.

There are new methods being developed every year, making laser eye treatment more accurate than ever before. The decision of one procedure over the other should involve careful consideration and discussions with your doctor to figure out which method would work best for your eye condition and personal preference. The technologies vary in the specific eye conditions they are able to treat, as well as the recovery time. A good surgeon will explain all of the options to you and help you choose the best one for your situation.

LASIK Laser Eye Treatment

by Mathew in Laser Eye Treatment

Laser eye treatment can be a great procedure if you hate the annoyance of glasses or contacts. There are new procedures for laser vision treatment being developed every day. One of the most popular is LASIK eye treatment. This outpatient procedure offers a quick recovery time, almost instantaneous vision improvement, and a very low risk of complications. The ability to create perfect or near-perfect vision is an exciting new possibility from LASIK.

LASIK vision treatment is an incredible development, increasing the success rate of laser eye surgeries. Laser eye treatments become more and more successful each year; LASIK surgery is one of the newest methods that is helping to increase the success rate. Here’s how LASIK works:

Like most methods of laser eye treatment, LASIK is most often used to correct nearsightedness, farsightedness, and astigmatism. However, it can also be used to correct several other vision issues, including, macular degeneration, and presbyopia, which is blurred vision when focusing close-up.

What makes LASIK unlike other forms of laser vision treatment is the way that the surgeon gains access to your cornea. LASIK stands for Laser Assisted In Situ Keratomileusis, which is the process of creating a flap in the corner of the eyeball. Once your eye has been numbed with anesthetic drops, the surgeon will create this flap. Then, the underlying cornea is reshaped using a computer-guided laser beam. This precise reshaping of the cornea is what changes your vision.

After the surgery, the flap is simply repositioned, where it will stay without stitches. Unlike other forms of laser treatment for eyes, this method comes with little discomfort, and a fast recovery time, as your eye will be completely healed within just a few days. As with most methods of laser eye treatment, you should plan for a few days off from work and other obligations to recover from your surgery.

LASIK eye treatment has recently received substantial attention, and for good reason. The results can be quite impressive, immediately improving your vision and allowing you to go without glasses or contacts. LASIK is painless, and the procedure takes just a few minutes. Laser treatment for eyes is getting better each and every year, and LASIK is a very exciting new development in the world of eye surgery. Consult your eye doctor if you are considering LASIK, or any other kind of laser eye treatment.

The Different Laser Treatments For Eyes

by Mathew in Laser Eye Treatment

Many people assume that LASIK and laser eye treatment mean the same thing. In fact, LASIK is just one technique for laser eye treatment. There are new methods being developed every year, making laser eye treatment even more accurate. The one you choose should be based on your specific eye condition, as well as personal preference. These surgery options are very sophisticated, so you should understand your eye correction prescription before choosing one. Here are a few of the most commonly used methods:

  • LASIK - This is the most commonly used procedure for people who are nearsighted, farsighted, or have astigmatism. A small incision is made in the corner of the eye, creating a flap. Then, a computer-guided laser beam is used on the cornea underneath the flap. This precise reshaping of the cornea is what changes the patient’s vision. At the end of the surgery, the flap is simply repositioned over the eye. Healing time is just a few days.
  • LASEK - LASEK involves the lifting of the outer layer of your eye with a fine blade. Then, alcohol is used to loosen the tissue. Finally, the laser is used underneath it, on the cornea, just as it is used in LASIK. This option offers a very fast recovery time, usually within a day or two.
  • Zyoptix - A very new procedure, this technique can be used for many eye conditions. The laser works more quickly, allowing the surgeon to be more accurate when reshaping your cornea. This can produce better vision results.
  • PRK - Photorefractive keratectomy is one of the oldest procedures, and it is not as commonly used today. With PRK, the outer surface of the eye is removed using a laser. This procedure works best on people with mild or moderate eye conditions. On the downside, the recovery time is more gradual than with newer method, and it can take several months for your eyes to fully heal.

There are several other options as well, which are used to correct specific eye issues. All of these methods involve the reshaping of the cornea to change the vision. They differ in how the cornea is accessed by the surgeon, as well as how the cornea is reshaped. Discuss all of the possible options with your laser eye surgeon before deciding on a method for your laser eye treatment. A good surgeon will explain all of the options to you and help you choose the best one for your situation.

How Does Laser Eye Treatment Work?

by Mathew in Laser Eye Treatment

Laser eye treatment offers many benefits to patients and is wildly popular as an elective surgery.  Yet for all its popularity, the surgery is not always well understood.  As you should never agree to a procedure that you don’t fully understand, this article will review the basic mechanics of laser treatment for eyes.

The key thing to keep in mind is that there are two factors that impact your vision.  The first factor is the shape of your eye.  The second factor is your age.  Laser eye treatments address the first of these two factors.  No cure has yet been found for the second, but doctors are working on it!

How does it work?

Laser surgery focuses on improving vision by reshaping the eye.  The reshaping is accomplished by targeting a specific portion of the eye, as reshaping the whole eye would be too complex.  The cornea of the eye is the element that is reshaped by surgery.

According to the University of Wisconsin Medical Center, the cornea is responsible for 65% of the eye’s refractive power.  In layman’s terms, that means the cornea handles the bulk of the light bending that is needed to give you a clear picture of the world.  Even small changes in the shape and texture of the cornea can have a major impact on your focus and vision.

What Happens During the Procedure?

During a laser eye treatment, trained doctors use a specially designed blade to cut a small flap to access the cornea.  They lift this flap and then use a specially designed laser to work on the cornea of your eye to create a new shape that will give you better vision.  Then they replace the flap, smooth it into place over the reshaped area, and set it to heal.

The whole process will be mapped out before any cutting takes place using a measured picture of your eye.  It is an incredibly precise topographic map, like a 3-D model of a landscape, only better.  Doctors measure changes that need to be made not in inches or millimeters but in micrometers!  The tiny, tiny levels of change needed to improve your focus are dependent on the shape, age and health of your eye, and also why occasionally some treatments need to be touched up later.  Everyone heals differently and sometimes quarters and halves of micrometers will make the difference.

The tiny measurements are also why the lasers used in the surgery are constantly remapping the position of your eye.  The most commonly used surgical laser for eye treatments, the Excimer laser, remaps your eye position up to 4,000 times per second during surgery.  The speed of the laser and the small operating area means that the total surgery time may be less than 30 minutes.

What Takes Place After Surgery?

After your laser eye treatment, you will be given antibiotics and anti-inflammatory drops for your eyes.  Some patients even wear special medicated contact lenses for a few weeks after the surgery.  Most people heal completely within just a few weeks and go on to enjoy a lifetime of good vision as a result of their choice to have laser eye treatments.
