Laser eye surgery technology
At Vision Correction London, we pride ourselves on using the best available technology for our patients. The best surgeons combined with the best technology allows us to achieve the best outcomes. Technology is ever changing and in order to keep up to date both with hardware and software improvements as well as surgical techniques, our team attend regular conferences and meetings allowing them to stay at the cutting edge of laser eye surgery.
The excimer laser is the laser used to reshape the cornea (the front window of the eye).
Developed in the 1980’s, it revolutionised vision correction surgery allowing for accurate micrometer precision with no collateral damage to surrounding tissue.
With each year, the technology and software improves and we now have lasers that can treat a prescription in seconds rather than minutes.
Most modern lasers offer the ability to perform wavefront optimised or wavefront guided procedures essentially preserving the good parts of the optical system and treating the weak. This explains the reasons why many patients report their vision better than it ever was with glasses or contact lenses following laser vision correction.
At Vision Correction London, we always include wavefront treatment as standard and don’t charge an additional fee for this. We want to offer the best treatment available and as such don’t offer different levels of treatment, only what we believe is the best treatment for you.
Eye Tracking Laser Technology
Eye Tracking Laser Technology
During the procedure, in order for the laser pulses to be delivered where they need to go, the eye needs to be tracked during treatment. Micro-movements of the eye need to be accounted for and the laser pulse needs to be adjusted accordingly.
Eye tracking technology has improved further in recent years and most modern lasers have this incorporated into their systems. The Eye Tracker is faster than your eye can move and as such always ensures the laser pulses are delivered at precisely the right points which further increases the accuracy of the procedure.
In this procedure, a flap of superficial cornea is made by a special device known as femtosecond laser. The flap is reflected and laser applied to the underlying residual cornea. Once the treatment has ended, the flap is folded back and smoothed into its original position. This is the most commonly used method and allows for fast visual rehabilitation.
Femtosecond lasers work by using laser energy in ultra-short pulses. When the energy is directed at specific points, a cleavage plane can be created which is how the LASIK flap is made. Femtosecond lasers for flap creation are now the standard of care in LASIK laser eye surgery. They allow for increased precision and have significantly increased the safety profile of laser eye surgery since their introduction.
The procedure has become more popular in the laser surgery market recently and essentially uses the femtosecond laser to create a thin lenticule in the cornea which is then removed through a small “SMILE” shaped incision.
There are some advantages and disadvantages compared to the LASIK procedure. The advantage being that a flap in the cornea is not required. The disadvantage being that recovery does take longer at present compared to LASIK and if problems develop, they are harder to resolve compared to LASIK.
This technology is likely to improve over the next few years with the addition of better eye tracking technology further improving the accuracy of treatment.
At Vision Correction London, we use the best technology available and take time to assess your eyes and vision so we can customise your treatment to give you the best outcome.
