One of the most popular methods of doing away with eyeglasses is the latest eye laser technology, Femto-Lasik. It is a procedure that has had comprehensive scientific research and follow-up protocol to ensure the surgery is safe and sound. The surgery represents peak precision and has achieved the desired results in 98% of procedures.
Femtosecond is the most recent type of laser method used to cutting the microscopically thin flap on the cornea’s surface, thereafter; the Excimer laser will correct existing refractive errors. Femto-Lasik successfully and easily treats eye dioptre prescriptions from -12 to +6.
The advantages of Femto-Lasik
Even flap thickness
Femto-Lasik helps the eye surgeon determine beforehand the thickness, measurement and form of each flap. When it comes to higher refractive errors, knowing these details will make the treatment more successful.
When it comes to other benefits of Femto-Lasik, you will be guaranteed excellent visual results. Healing and recovery will take a shorter time and your vision will improve quickly. In addition, the patient will experience minimal discomfort because the Femto-Lasik laser places less pressure on your eyes.
Will this treatment work for you?
If you suffer from shortsightedness, long sightedness and astigmatism, Femto-Lasik is the best treatment option. Also,
UltraLASIK is to achieve superior vision correction while ensuring the highest level of safety. The new UltraLASIK, combined with the Custom Wavefront, is used to create an ultra-thin flap on the front surface of the eye. The 60 KHz laser beam will then pass harmlessly through the outer layers of the cornea to an exact focal point where the flap will be placed. The high speed pulses of the laser gives increased accuracy that allows the surgeon to place the flap at the most ideal position for best results. Also, the precision of this procedure minimizes the risk of complications allowing more people to be qualified for this treatment.
After the flap has been lifted, cool laser pulses are used to gently reshape the cornea and correct the imperfections in your vision, making way for a virtually perfect eyesight. The flap is then replaced, acting as a protective bandage, healing on its own.
In a simpler sense, EPIthelial LASIK laser eye surgery or Epi-LASIK is a combination of both LASIK and LASEK surgery with subtle differences in execution.
LASIK involves cutting a flap in the cornea using a sharp blade or laser that runs a risk of cutting the flap thicker than necessary. LASEK, on the other hand, also cuts the flap as thinly as possible while retaining the hinge of the flap on the eye. EpiLASIK basically does the same thing but with the use of a blunt plastic oscillating blade as opposed to the LASEK’s finer blades. Also, LASEK uses alcohol to loosen the epithelial flap while EpiLASIK has an epithelial separator to do it, reducing the risks of the adverse effects of the alcohol that can possibly kill the epithelial cells.
The epithelial flap is harder to make for people with steep corneas that is why the EpiLASIK method is ideal for people with corneas that aren’t too steep and those only with mild myopia.
When the epithelial flap has been cut properly, it is lifted and folded back in order for the surgeon to work on the cornea beneath it. An excimer laser is then used to reshape the corneal tissue. Lastly, the epithelial flap is put back into place with a spatula-type equipment. Special contact lenses are placed on the eye for protection during the healing process of the epithelial cells.
PresbyLASIK or Multifocal LASIK is a type of laser vision correction surgery that changes the shape of the cornea to fix both your near and far vision. This procedure is mainly used to correct presbyopia or the natural loss of near vision due to age. If you are nearsighted and have presbyopia, you may be able to see up close without your usual eyeglasses or contact lenses but not when you are wearing them.
Before PresbyLASIK, people with presbyopia uses multifocal eyeglasses, multifocal contact lenses or artificial lenses (IOLs for cataract surgery) which can be a hassle for some activities. Sophisticated technology now enables multiple or progressive zones to be incorporated into artificial lenses to enable “multifocality” or sight at all distances. Unlike conventional LASIK which only fixes one vision only – depending whether you are farsighted or nearsighted – multifocal LASIK creates more than one power zone on the front surface of the eye, giving you the ability to see at all distances. This is done by reshaping your eye’s clear surface into precise contours that alter the way light rays enter your eye to achieve focus.
As of now, the only currently available FDA-approved LASIK procedure for presbyopic eyes is monovision. This means one eye is corrected to be far-sighted and the other one is enhanced for near vision. With multifocal LASIK, however, the cornea will be reshaped using excimer laser so that both eyes have different zones for near, far and intermediate vision. The brain then automatically chooses which zone it needs to be able to see clearly, depending on whether an object is near or far away.
