Lasik_Eye_Surgery_ _Would_you_have_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. 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.

With the advent of the laser, a more modern method became the norm, called Photorefractive Keratectomy (PRK). This procedure involved the removal of the outer cells of the cornea (epithelium), and then reshaping the corneal surface with an excimer laser, a procedure known as ablation. The epithelial cells were then allowed to grow back normally. Because epithelial cells on the eye regenerate exceptionally quickly the cornea would generally heal completely within a few days. 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.


´╗┐Being the largest organ of our body, it is hardly surprising that the skin takes much of people's attention, care and money. While women have always been keen in doing painstaking ways to take care of their skin, men are also beginning to pay attention to their skin. It is a known fact that skin consists of numerous cells. Every day, a good number of these cells die to be substituted by new ones. Aging disrupts the normal flow of this process and this results in various skin problems, such as dullness, wrinkles and dark blotches. Fortunately, technology has come a long way in helping people bring back skin what-has-beens. Over the years, various skin care inventions have been created, offering to reduce or totally remove every blemish there is. Among them is microdermabrasion.

1. What is Microdermabrasion?

Microdermabrasion is a cosmetic procedure targeted in removing dead cells, stimulating the production of more living cells to replace them, as well as the production of collagen to give skin a more supple look. Simply put, microdermabrasion is a non-surgical, laser-free, chemical-free and acid-free way of achieving healthier and younger skin. Using a deep exfoliation process, this method was created to rejuvenate the skin, plus treat various kinds of skin damages, including acne scars, spots and blemishes, uneven skin color, large pores and blackheads. It is considered generally safe for all types and colors of skin.

- Microdermabrasion traces its beginning in Italy

- First introduced in 1985

- Low risk procedure

2. The Process

Magic wand takes a new definition with this procedure, as it uses a hand piece that performs two tasks: first, it releases crystals called Corundum on the skin's surface, that causes the gentle abrasion process. This removes the problematic surface layer of the skin, revealing newer and smoother skin. Secondly, the device uses a vacuum process that causes stimulation of blood circulation, as well as the production of collagen to make skin smoother and improve its elasticity. A session, usually conducted weekly, involves two treatments, lasting for an average of 30 to 40 minutes, depending on the thinness or thickness of the skin being treated.

3. What Are The Advantages Of Microdermabrasion?

- Non-surgical

- Uses no chemical

- Causes less discomfort

- No risk of side effects such as scarring

- Painless

- Anesthesia-free procedure

- Fast recovery

4. How Soon Will The Results Be Over?

Incredulous as it may sound, microdermabrasion's results manifest immediately. After the first session, the patient's skin will already show a pink glow, and will look smoother and softer. Continued treatments will eliminate skin imperfections and result to healthier skin. Full results usually take 10 treatments.

5. Who Should Undergo Microdermabrasion?

It is because of its safe and painless procedure that everyone may undergo this skin treatment. Offering a fast recovery, it is recommended to those who cannot accommodate a long break or time off, such as employees and students, or to those who are active in sports and other outdoor activities. Since the treatment is low-risk and practically universal to all skin types and colors, it may be given to those with sensitive skins, especially those who are allergic to certain chemicals and skin products.
