Lasik Surgery - What Exactly Is It?

There are a number of methods used to surgically correct eyesight nowadays but the most popular choice is Lasik (Laser-Assisted In Situ Keratomileusis). However before the use of modern technology such as laser beams and computers, the original technique was Radial Keratotomy (RK). This involved an Ophthalmic surgeon with a steady hand and a sharp scalpel to make a series of radial cuts in the cornea (the front 'window' of the eye), which when healed, would flatten and therefore reshape the cornea.

With the advent of the laser, a more modern method became the norm, called Photorefractive Keratectomy (PRK).

This would theoretically correct short sightedness. The problems occurred mainly due to the fact that the depth of the incisions could cause weakening and progressive flattening of the cornea, after the procedure. This could lead to a number of defects such as progressively blurring vision and starburst patterns around lights.

 

This technique was certainly more successful than RK but did have its own complications. Side effects such as halos round lights and reduced contrast vision were experienced by almost everyone, along with some corneal 'hazing'. Although serious complications were rare there was always the risk of infection due to the lack of epithelium protection during the healing phase.

 

Then in 1990 LASIK surgery was developed by a Dr.Lucio Buratto of Italy and Dr. Ioannis Pallikaris of Greece, and it quickly became popular because of fewer complications and was certainly more accurate. The procedure involves cutting a corneal 'flap' with a special high precision blade called a microkeratome. This flap was then folded back with the front surface epithelium still intact. The cornea can then be reshaped with the laser and the flap is laid back down. The epithelial cells that were cut with the microkeratome quickly heal and therefore the outer surface is a nice continuous layer that securely holds the flap in place permanently. Although quite uncommon, some complications such as dry eyes, debris under the flap, ghosting or poor vision to name a few, do occur from time to time.

 

Another technique that is also used nowadays is LASEK or Laser-Assisted Sub-Epithelial Keratectomy (as opposed to LASIK). It can be used if the cornea is too thin to undergo lasik surgery where the microkeratome cuts deeper than the epithelium. In LASEK, the epithelium is peeled off as a layer to allow laser ablation underneath. During the procedure the epithelial layer is preserved with a special chemical solution and then replaced afterwards, so as to allow natural healing. There is generally more pain and slower visual recovery with this technique.

 

PRK and LASEK allow the epithelial layer to heal entirely and therefore don't run the risks of a dislocated corneal flap which can occur due to trauma, even after many years with LASIK. However, the latter is still the most commonly used procedure. There is still a lot of fear amongst many about the long term effects of laser surgery, but it has been around for quite a while now in its different forms. It seems that more and more people are opting for this surgery, due to a number of reasons whether they be for convenience or cosmetic. With the information technology of the internet, increased knowledge on the subject is much more widespread, so barring any major negative eventualities this trend will almost certainly continue.

Is Lasik Eye Surgery For You? Or Are You Too Sqeemish!

 

For those of you that don't know Lasik stands for Laser-Assisted in Situ Keratomileusis. In Lasik the surgeon cuts a small flap in the cornea and uses a laser to reshape the inner area of the cornea. Problems with the cornea can be related to many vision troubles such as; Hyperopia or farsightedness and Myopia or nearsightedness). Also problems like Astigmatism can also be caused. The good news is that eye surgery and lasik in particular resolve many of these eye defects.

 

However, whatever may be your procedure of choice, attaining excellent results is largely dependent on the expertise of your eye surgeon.

 

The sheer number of different of surgical procedures for correcting vison problems can leave you uncertain of the best one for you. lasik is by far the most preferred corrective eye surgery, and hence it is imperative that you choose an eye surgeon with a great deal of experience.

 

If you are thinking of going in for lasik eye surgery then this is what you can expect. Before getting lasik you will be examined by a qualified eye doctor or ophthalmologist. During this examination standard eye tests and computer images of the cornea will be taken to build up a picture of the eye and ascertain what corrections need should made. In addition your overall health is also considered when deciding if you will be a good lasik patient. Any conditions, such as dry eye syndrome, may affect your ability to get this type of eye surgery, but in these cases other treatment may be available.

 

You will be able to go home on the same day as you eye surgery and should have recovered within just a few days. Minor irritations may take up to a month to disappear. The vast majority of people who undertake this surgery will be able to see much more clearly straight after surgery and this improves still further over the next few days.

 

Some people may experience some side effects like light sensitivity or night time vision problems. In even more rare cases other difficulties like infections can also occur, but most often, if you follow your doctors orders these things can be avoided or cured quickly with eye drops of medication. Other side effects are more long term. These can occur for 6 months or longer. These are: dry eyes, blurred vision, difficulty seeing at night, light sensitivity, glares, and vision fluctuations. If you cannot handle any of this, then this eye surgery is not for you. Attaining excellent results is largely dependent on the expertise of your eye surgeon. Lasik is by far the most preferred corrective eye surgery for many, and so it is imperative that you choose an eye surgeon with a great deal of experience and who is using the best medical equipment available.

 

This type eye surgery has been big news over resent years as the changes to peoples vision and quality of life can be astounding. People who could not see without glasses are getting almost 20./20 vision and word of mouth about these 'miracles' spreads fast.. With many people flocking to have the procedure done it has become one of the most popular eye surgeries. However, before committing to the surgery you should look into what lasik is and what it can do for vision in general and your sight in particular. Before committing yourself ask to speak to people who have had the operation with the organisation you are thinking of using yourself. Ask about the good and bad points of both the operation and the company itself.

 

As lasik is a fairly new medical procedure the long term risks are not known and it is not possible currently to cure the need for reading glasses as this is problem is more connected with the weakening of the eye muscles over time rather then the corner. As a potential candidate for lasik you must discuss all your concerns and expectations with your surgeon before the procedure is carried out to ensure you completely understand the process and outcome possibilities for you as an individual.

 

Finally, many people can't even think about anyone touching their eyes, never mind someone pointing a laser into them. If you are reading this article and are feeling a bit squeamish then perhaps lasik is not for you!

Is Lasik Eye Surgery For You

We're a nation that's getting sick and tired of always cleaning our glasses and dealing with contact lens solutions and problems. Many of us tire of looking for where we set our glasses or the drudgery of trying to see if they aren't with us all the time. With Lasik eye surgery, those of us with less than perfect vision now have an affordable option to correct our vision. Since the 1980's, Lasik eye surgery has successfully been used to correct many of the known maladies that keep us from enjoying clear eyesight without the need for glasses or contacts.

LASIK stands for Laser-Assisted In Situ Keratomileusis and is a procedure that reshapes the cornea.

The process that is used for this sounds a bit dangerous, but is being performed with huge success rates all over the world. The way Lasik eye surgery works is relatively simple, fast and with minimal pain. And fortunately, the price of lasik eye surgery is becoming more affordable. When first approved, the cost of a typical Lasik surgical procedure was thousands of dollars per eye. This was also with equipment not nearly as precise or technologically advanced as we have in the 21st. century. The equipment is much more precise and the cost has come down. When you consider the cost of those glasses and contacts Lasik truely can save you money in the long run.

 

The cost continues to come down due to many factors. Don't let the lower price fool you however. Today's results are better and can correct many more refractive eyesight issues that when first approved. This is due to better equipment, more education for the doctor and the wealth of experience now available. Many more doctors are also offering Lasik surgery directly through their own office or at established eye surgery centers or institutes.

 

Today, the cost of obtaining a qualified Lasik procedure continues to drop. In many of the larger metropolitian areas, the cost has reached as low as 500 dollars per eye. While this procedure does not seem to be very complicated and certainly does not take a lot of time, it is not a perfected science. The reason for this is each eye is shaped differently and the amount of slope on the cornea affects the level of vision problems. The ophthalmologist must gauge how much cornea needs to be removed/ reshaped in order to correct the patient's vision to 20/20. This is difficult because there is no way to know how the cornea will react to the laser and how close to perfect vision the patient will have. Then, the ophthalmologist uses a specialized laser that sends pulses to the stroma that reshape the cornea. Then, the flap is replaced and the procedure is completed.

 

As a result, lasik eye surgery works very well for patients who want to improve their vision. However, it is not guaranteed to return your vision to 20/20. It may, however, be successful, may improve it drastically but not perfectly and the eye might not react the way the ophthalmologist imagines and leave the patient with less than perfect sight. When this happens it can still necessitate the use of glasses or contacts. Fortunately, lasik surgery is successful and patients are pleased

 

the majority of the time. Many patients have been able to go from the thick pop bottle eyeglass lenses to the nice thin comfortable lenses because of the success of the surgery. The goal isn't always perfect vision but improved vision. Most people however, are able to have 20/20 vision after having Lasik Eye Surgery.

 

Take the time to think about the risks and benefits to Lasik Eye Surgery and research this procedure before deciding to have it done. Make sure you find a reputable Lasik surgeon that has performed many procedures. Your eyes are one of your greatest assets.
