What is True About Intra Lasik?

Now that Lasik vision correction surgery has been accepted for a number of years, there are several popular options for the procedure. One of these is IntraLasik, or Intralase, or bladeless Lasik. As the name implies, there is no cutting of the eye with a blade, instead the flap in the eye is made using a laser. Since bladeless Lasik is a newer procedure, there are a number of opinions around about how well this procedure works. Let’s look at several of these and determine which of these are true or false.

First, more Lasik clients get 20/20 vision or better using IntraLasik. Any Lasik procedure cannot guarantee perfect vision for every client, though more than 90% get results to at least 20/40 vision. However, it is true that the new techniques of IntraLasik do get even better statistics for giving clients clear vision.

Some are concerned that the laser that makes the corneal flap is standard, and cannot be tailored to each individual eye like can be done by the Lasik surgeon when using a blade. This is not true. The Lasik physician has control over the use of the laser for each individual in the same way that he can control the microkeratome blade.

IntraLasik can be used for both a standard and a custom Lasik procedure. This is true. Custom Lasik procedures using Wavefront technology (another somewhat recent advance in Lasik vision correction) can easily be used with a laser making the initial flap. This custom Lasik procedure, though more costly, is of great benefit for people with unusual eye shapes or problems.

Some have heard that using the laser is less accurate than the standard Lasik procedure. This is not true, since lasers can be controlled to micron level accuracy. This gives the Lasik physician extreme control to create exactly the flap needed for this particular individual eye: the precise size, shape, and depth for successful completion of the Lasik procedure.

Another common fallacy is that IntraLase has not been around long enough for trusted Lasik physicians to have confidence in it. On the contrary, many of the most honored Lasik physicians strongly endorse IntraLase due to the track record of very good results from the Lasik procedures. In addition, the quality of the machines and the precision that they give these Lasik physicians is very impressive. Many of the top flight Lasik doctors recommend this as a procedure of choice, assuming cost is not a significant variable in the decision of which Lasik procedure to use.

Similar to the objection above, some people think that Intralase is not a sufficiently test Lasik procedure option. On the contrary, more than one million of these procedures have been performed, and the impressive track record for this Lasik procedure has been discussed above. More and more Lasik physicians are trained in this option, and we will see many more such Lasik procedures in the future.

We hope that this discussion of bladeless Lasik has given more accurate information to those considering this Lasik technique. Please discuss this option with the professionals at your local Lasik center.

What is the Initial Lasik Eye Exam Like?

The first significant step before the Lasik surgery is to have a comprehensive eye examination, in order to be sure that you are a good candidate for the Lasik procedure. A map of your eye will be created during this exam. This map is used in order for the Lasik physician to determine how to reshape your eye to give you the clearest post-operative vision possible.

This eye exam will do several things. Your eyes will be dilated in order to see if there are any irregularities within the eye itself. The thickness of the cornea will be measured, and a precise map of the cornea will be generated. The “refractive error” (or the reason why your vision isn’t currently perfect) will be accurately analyzed in order for the Lasik procedure to get the best results possible. Finally, how your eyes generate tears will be closely looked at, as good tear production is essential for the health of every eye.

Before or after these measurements, the Lasik physician will discuss your past medical history to see any previous operations or any ongoing health problems. A few chronic conditions may make the Lasik procedure not a good option for some people, and also women currently expecting should wait for some time after delivery. The physician also will discuss the expectations the Lasik client has about the operation and subsequent changes in their lifestyle.

Though most people pass through this Lasik eye exam with flying colors, be prepared for some suggestions or serious discussion. Your eye map may indicate that a newer form of Lasik procedure might be better, such as one that generates a three dimensional waveform for each eye. Tear production issues may indicate that the Lasik procedure is not the best option for you, and the Lasik physician may recommend another solution.

If all goes well and the Lasik procedure is scheduled, the physician will review the treatment plan and what the client should do to prepare for the Lasik surgery. This plan may vary slightly between patients, but in general will look something like the schedule below. Always follow the recommendations of your Lasik physician closely.
First, contact lenses should be avoided for several weeks prior to Lasik vision correction, since contacts can slightly affect the shape of your cornea. It is important to let your eyes rest in order to get the most accurate Lasik vision improvement possible. Hard contacts should be avoided for a month, soft contacts for at least two weeks.

Stop using any lotions, makeup, or anything else that could possibly get into the eye the day or two before surgery. It is important to have your eyes as rested as possible before the Lasik operation. Also, arrange for someone else to drive you home after the Lasik procedure itself.

These are the most common steps to prepare you for an easy and successful Lasik procedure. Make sure you give the doctor all information needed for your case, and follow his directions closely. The Lasik procedure will give you a new outlook in life!

What is a Wavefront Lasik Procedure Like?

Let’s walk through what a client experiences when attending a Lasik center for a Wavefront Lasik procedure. The procedure itself generally only takes between five and ten minutes for each eye in total, and both eyes are done during the same procedure. The actual time to reshape the eye with the Lasik excimer laser is usually less than 15 seconds per eye.

Any person’s vision problems are generated by small “aberrations” within the eye that prevents the light from focusing objects as they should. The Lasik equipment locates and classifies these aberrations and then processes them so that the Lasik physician will correct these and allow the light to focus properly once the eye has healed.

In a Wavefront Lasik procedure, the patient stares at one point while a light is sent into the eye, which is reflected back and read by a Lasik Wavefront sensor. The distortions in this reflected light are mapped using a small computer within the Lasik system, and then this information is used to guide the laser that treats the eye.
Once the light creates the map for the eye, the Lasik surgeon has to create a small flap to access the cornea. This is done using a laser (this type of Lasik procedure is known as IntraLasik, or bladeless Lasik) or a small blade known as a microkeratome.

This flap is then opened to allow the cornea to be reshaped by the Lasik system.The excimer laser actually reshapes the cornea, which is the crucial part of the Lasik procedure. In order to determine exactly how to reshape it, the map created earlier by the Wavefront sensor is used to direct the beam of light accurately. The Lasik physician uses these precise tools to get the clearest vision results possible.

This custom Lasik procedure can not only correct such standard problems as nearsightedness, but can also address aberrations that create light halos, glare, haze, or starburst patterns. Once the Lasik physician determines that all relevant aberrations have been eliminated, he replaces the flap in its proper position, where it adheres normally and will heal naturally.

As mentioned earlier, this entire Lasik process takes between ten and fifteen minutes per eye. A patient gets a mild sedative and eye numbing drops to make the procedure both relaxing and painless. Most people notice an improvement in vision due to Lasik almost immediately.

Once the Lasik procedure is finished, you will get some eye drop medication to lubricate and protect your eyes. This medication (and the liquid in the drops themselves) may cause some blurring, and so for this reason (and to avoid any eyestrain) you should arrange for someone else to drive you home. It is also a good idea to go to sleep as soon as possible after the Lasik operation in order to promote even faster healing.

To promote optimal healing the Lasik physician often gives a plastic shield to wear over your eyes for the first night or two. Follow closely any recommendations by the Lasik physician. Do further investigation into this great new Lasik procedure, and get a clearer focus on your future!
