Laser-assisted in situ keratomileusis (LASIK) laser eye surgery has been known for helping people achieve that much desired 20/20 vision. While LASIK still remains popular and in demand, there is a new treatment that is touted to be superior to the conventional LASIK laser eye surgery.
The new treatment called wavefront-guided LASIK is a customized laser vision correction system for nearsighted patients. It can measure and correct unique imperfections in your vision. The customized measurements and treatment plan help you regain that 20/20 vision or even better without relying on glasses or contact lenses.
Normally, the wavefront of the eye has a flat surface since light rays travel uniformly through the eye. However, when you have an imperfect eye, the wavefront map becomes wavy since some light rays reach the retina ahead of the others while some hit the retina at different locations.
Conventional LASIK laser eye surgery relies on your eye glass prescription without measuring the wavefront. On the other hand, wavefront LASIK measures the wavefront and the focusing errors in the eye. This is done by looking into the light while the wavefront device uses a camera sensor to measure the light rays that reflect out of the eye. A virtual map exhibiting the precise locations and extent of the visual aberrations are generated.
Here are some things you can expect if you undergo the wavefront LASIK laser eye surgery:
• You will be asked to stare down a wavefront analyser to give you a preview of your potential vision and to take pre-operative measurements.
• Your eye surgeon may opt to create a trial lens that will incorporate the correction your eyes need. The lens will be fitted into a trial frame to give you an idea of what your new and improved vision will be like.
• The entire wavefront LASIK laser eye surgery procedure only takes about 10 minutes.
• A microscopically thin and hinged flap will be cut on the top of your cornea with the use of the precision instrument microkeratome or lately it is created using state of the art femtosecond laser. The flap will be carefully peeled back.
• The image of the wavefront will be transferred into a computer that controls the excimer laser. The computer will superimpose the map over the eye to enable the eye surgeon to adjust the laser to address the imperfections.
• The eye surgeon will zap the cornea with a series of rapid pulses from the laser. This will remove small and precise amounts of the corneal tissue and reshape the corneal tissue to correct astigmatism and nearsightedness. .
• You need not worry about the safety of the wavefront LASIK laser eye surgery. The excimer laser light does not penetrate into the eye, ensuring that other parts of the eye remain untouched.
• After the procedure, the flap will be replaced and the natural suction of the eyes will allow it to heal without stitches.
• This procedure may also be ideal for persons who underwent refractive surgery but continue to suffer from halos, distortions and glares.
Wavefront LASIK laser eye surgery may be a bit more expensive than the conventional LASIK surgery. Both procedures are usually not covered by health insurance plans. But with the benefits they provide, they are definitely worth the try.
We have seen thousands of patients that have had traditional LASIK and Wavefront Assisted LASIK. What is certain is that on average the patient that has the Wavefront procedure does see slightly better, especially in dim light. Given a choice between the two procedures we definitely recommend the Wavefront treatment.
