The Wavelight Refractive Suite from Alcon Laboratories Sdn Bhd is the first in Asia and the latest addition to Lee Eye Centre’s (LEC) collection of state of the art equipment. It is the only laser in the market which is approved by the FDA (Food and Drug Administration) of USA for treatment of nearsightedness up to 1400 degrees, farsightedness up to 600 degrees and astigmatism up to 600 degrees thereby giving it the widest range of treatment.
Corrective lenses such as glasses or contact lenses are wonderful optical aids which some of us have come to be very dependent on. Myopia (near-sightedness) is increasing in prevalence and ongoing research into this “epidemic” has shown that the urban population, particularly of Chinese ethnicity, is more prone to developing myopia and this is occurring at a younger and younger age. Consequently, more and more children (and adults) are dependent on these corrective lenses for good vision.
However, this “crutch” that are the corrective lenses, has its drawbacks and nowadays, the option of laser vision correction is becoming more appealing as the technology improves by leaps and bounds to make the procedure extremely safe, fast and virtually painless.
Laser Vision Correction
There have been so many uses for laser in eye care but most people nowadays would associate laser treatment for the correction of near-sightedness, far-sightedness or astigmatism. Surgery for the correction of these refractive errors is called refractive surgery and laser is the most commonly used method.
This stands for Laser-assisted In situ Keratomileusis which for the layman is the use of an excimer laser to re-shape the cornea. This change in shape of the cornea will focus the light rays entering the eye sharply onto the retina. Patients who have had LASIK will get to enjoy good vision without their glasses or contact lenses.
How does LASIK work?
LASIK is an outpatient procedure that is fast, painless and very safe. An ultra-thin flap is first created on the corneal surface; this flap is partially lifted off to allow a highly specialised laser to reshape the cornea; the flap is then replaced and serves as a type of natural “bandage” (Figure 1).
Traditionally, this flap is created with an instrument called a microkeratome, which is essentially a metal blade used to cut the corneal surface. Technology has improved now and a special laser called the femtosecond laser is used to create this flap. This is even more precise and allows for even safer surgery and this “all laser” or “bladeless” LASIK is fast becoming the new standard of care for laser vision correction.
The Wave Light Refractive Suite was designed by Germans to integrate the 2 lasers not only with one another, but also with the pre-surgery machines which are used to assess the patients. This gives the advantage that all the treatment data recorded by the machines used to assess the patients, can be transferred by the click of a button to the lasers. This is called WaveNet and will reduce the chance of human error where the data has to be entered manually. All these features of the Wavelight Refractive Suite allow the surgeon to provide consistently excellent refractive and visual quality outcomes with an unparalleled level of safety when performing laser vision correction.
Who is suitable for LASIK?
It is important to remember that LASIK will only help to reduce dependency on glasses or contact lenses; it is NOT A CURE for refractive errors. Not everyone is suitable to have LASIK and a very complete and thorough examination of the eye is necessary to assess each potential candidate.
Are there side effects?
LASIK is very safe but nevertheless still a surgical procedure and therefore, should not be trivialized. Infection and inflammation is possible after any surgery and LASIK is no different but it happens very rarely. Serious complications are extremely rare and so far, there have been no reported cases of blindness from LASIK.
The Wavelight Refractive Suite being the first in Asia, and FDA approved, will see eye care being elevated to world standards and Ipoh given prominence as a centre for superlative eye care.
The FDA is a regulatory body which controls the use of drugs and medical equipment in USA and they are world recognized as the “gold standard” because they have very stringent criteria of assessment before a new drug or machine is approved for treatment.
