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!

Good Post Op Lasik Care

Good Post-Op Lasik Care

One of the most marvelous advancements using modern technology is the Lasik vision correction procedure, where in the space of fifteen minutes many people can reduce or eliminate their reliance on glasses or contact lenses. There is very little preparation for the surgery on the Lasik patient’s side, and the Lasik procedure itself takes less than twenty minutes.

With current technology and an excellent Lasik physician, there is a very high success rate for nearly all Lasik surgeries. Though not all patients get or keep exactly 20/20 vision, there is a vast improvement in the Lasik client’s vision and dependence on corrective eyewear. The two most important factors under the patient’s control is the choice of the physician and good post-operative care.

After visiting a few physicians or clinics that perform Lasik procedures, the client should have a very good idea of how they will be treated as a patient of that doctor. It is important to find a Lasik physician whose staff is responsive to questions and worries, and who are willing to see a post-operative Lasik client who is having a problem with their care.

This is one of the more common complaints of those folks that undergo a Lasik procedure: insufficient information about post-operative Lasik side effects, or a staff that simply says “Lots of people experience that, no problem,” when the patient actually should be seen by a member of the staff. A visit where the prospective Lasik patient talks with both the physician and one or two members of the staff will get an idea of how well a patient is welcomed once the Lasik procedure is completed.

During this initial investigative visit, the client should ask the Lasik staff for a list of common, temporary side effects that can be experienced after a Lasik procedure. The staff member should describe any cases where the patient should make a point of contacting the Lasik center, rather than just enduring the side effect. Cases of pain, intense itching, or seriously blurred vision may indicate an infection or other serious problem, and should be seen promptly. It is truly very rare that any of these complications exist after a Lasik procedure, but make sure that the center is willing to see the patient if they think something is more than mildly wrong.

One of the more common side effects after a Lasik operation is some form of dry eye, which often occurs during the nighttime while asleep. Not only is this uncomfortable, but if the eyelid sticks even slightly to the eye itself, it may dislodge the surgical flap done in the Lasik procedure, and delay healing of the eye. If this occurs, the Lasik center has several different viscosities, or thicknesses, of eye drops to alleviate this problem. The staff should be promptly notified so this problem can be addressed immediately.

A good, responsive staff surrounding an excellent Lasik physician is the most important component in how to select a doctor. Interviewing the physician and staff about all aspects of the Lasik procedure, both the procedure itself and post-operative care, is the best way to make an excellent choice.
