Laser eye surgery has been around for quite a while and numerous people have taken advantage of the procedure especially LASIK. This is because it is low risk, relatively easy-to-execute, quick and recovery is limited to around a month. Still, the procedure is still invasive. LASIK utilizes a laser or microkeratome to reshape the eye’s cornea in order to improve visual acuity. The procedure involves having flaps cut by the laser on each eye. Because of this people sensitive around the eyes or uncomfortable with the idea put off getting the procedure. However, with this new innovation they might not have to any longer.
ReLEx SMILE (Small Incision Lenticule Extraction) is the latest innovation in laser eye surgery procedures. It is helmed as the third generation in keyhole surgery that uses laser pulses to reshape the cornea and correct shortsightedness. This new cutting-edge technology is a revolution because it is less invasive than LASIK and allows correction of even higher myopic prescriptions. During the procedure, the state-of-the-art Carl Zeiss VisuMax laser places a series of pulses which are less than 1/100th of the width of a human hair onto the centre of the cornea.
Most distinctively, it is less invasive because it does not require a corneal flap. The laser pulses are used to outline the tissue that needs to be removed to reshape the cornea, and a tiny tunnel is then formed, through which the tissue can be removed. Hence, there will be less flap complications. Additionally, through not cutting a flap the cornea remains stronger. This is advantageous to those with higher powers or thinner corneas. In short, more people are eligible for the procedure than LASIK. The cornea nerves are also preserved which helps reduce post-operation dryness.
Furthermore, the lack of a help leads to quicker healing and post-operative recovery. The procedure itself can be completed in 15 minutes. The use of numbing drops also makes it the most comfortable procedure thus far for patients. Results are roughly the same as LASIK but overall it is better because it is:
- Less invasive
- Quicker procedure
- Faster recovery
- More comfortable
- Better for people with higher prescriptions and thinner corneas
