Laser Eye Surgery Accuracy at Optilase
Laser technology has evolved rapidly since the idea was first tossed about by no other than Albert Einstein in 1917.
Naturally, Einstein was onto to something, and lasers (Light Amplification by the Stimulated Emission of Radiation) are now pretty much incorporated into almost every aspect of modern-day living, used in everything from DVD players to food thermometers.
Made up of light waves of a certain wavelength that travel in the one direction, laser technology is used in Laser Eye Surgery because of its pinpoint accuracy and instant results.
What types of lasers are used during Laser Eye surgery?
Laser Eye Surgery at Optilase is a completely blade-free experience that doesn’t involve anything going near your eyes except two computer-controlled lasers:
- Femtosecond Laser
- Excimer Laser
A Femtosecond Laser is used to create a smooth corneal flap that exposes the cornea so that Laser Eye Surgery can take place.
Advantages of the Femtosecond Laser
- No mechanical action is needed, i.e. there is no metal blade needed to manually make the incision
- No interference with the tear film, which reduces the risk of infection
- Risk of any vision complications significantly lower
- Aids a quick recovery
The application of the Excimer Laser to Laser Eye Surgery has revolutionized the procedure so that incredible accuracy can be achieved in vision correction.
So precise is the Excimer Laser, that it can remove microscopic amounts of tissue, as little as 0.25 microns (1/1000 of a millimeter).
The Excimer Laser uses a cool beam of ultraviolet light of a specific wavelength to safely ablate corneal cells without damaging adjacent tissue.
Advantages of the Excimer Laser
- Auto-tracking of eye movements
- Precise correction
What happens if I move my eye during Laser Eye Surgery?
Modern-day lasers have been developed using an automated eye-tracking system, so that if there are any involuntary eye movements during Laser Eye Surgery, the laser can adjust accordingly.
