LASIK stands for laser-assisted in-situ keratomileusis and Relex Smile stands for Refractive LEnticule Extraction, SMall Incision Lenticule Extraction. If you are thinking of getting a corrective eye surgery, and are considering these two procedures, then this article will be of great help.
ReLEx Smile is currently the latest and most advance laser refractive surgery technique available to correct shortsightedness and astigmatism. This premium procedure is only available in a few laser eye surgery clinics around the world. Relex Smile uses a single femtosecond laser to create a lenticule in the cornea in just 24 seconds. This lenticule will then be removed through a small incision of only 2-4mm in size and this helps patient achieve good vision.
LASIK is one of the most commonly perform refractive surgery over the past decade. It reshapes the cornea by using 2 different lasers. Firstly, a femtosecond laser is applied to create a 22mm side cut around the cornea to create a flap. The flap is then lifted and the underlying cornea (stromal) is exposed to excimer laser to ablate the tissue and reshape it. Once completed, the flap is laid back in place for the eye to heal.
Both LASIK and Relex Smile procedure have the same benefit. Patients achieve good vision without optical aids after the surgery. However, Relex Smile has several benefits over LASIK. Since Relex Smile is performed through a keyhole surgery, no flap is created and thus no flap complication. It also leaves the cornea stronger post operatively as compared to LASIK.
In Relex Smile, incision is much smaller therefore healing is more rapid and discomfort is lesser. With just a 4mm incision, lesser cornea nerves are disturbed as compare to the 22mm side cut of LASIK, this results in lesser risk of dry eyes in patients undergoing Relex Smile.
Who should get these treatments?
If you have one of the following conditions, your eye doctor may suggest for you undergo LASIK or Relex Smile. This is especially if your eye problem is already affecting your daily activities. For example, you are having difficulties with sports or exercising with spectacles or contact lenses.
Patients with myopia or nearsightedness – this occurs when you eyeball is slightly longer than what’s normal or when your cornea is curving too sharply. It causes for the light rays to focus in front of your retina and blur distant vision. As a result, you can clearly see things that are close, but find it difficult to see those that are far away.
Patients with hyperopia or farsightedness – in case you have this condition, your cornea is either too flat or it is shorter than average eyeball. The effect is that the light that enters your eye will focus behind the retina instead of on it. This is the reason why near objects are blurry while distant vision objects are clear.
Patients with astigmatism –It occurs when the cornea curves or flattens unevenly. This disrupts focus of near and distant vision.
