LASIK

Get rid of your glasses today with the Laser technology

Laser Assisted in Situ Keratomileusis (LASIK) is the most commonly performed laser eye surgery to treat myopia, hyperopia, astigmastim and presbyopia. It’s the second most performed surgery in the world after cataract surgery.

 

LASIK procedure combines a femtosecond laser (this step was previously performed using a microkeratome (blade) but femtosecond technology proved its superiority and should be used in all cases nowadays)  used to prepare a flap in the corneal depth and an excimer laser in order to reshape the cornea and enable light entering the eye to be focused onto the retina for clearer vision.

In order to benefit from a LASIK surgery, you need to have a regular cornea as shown by corneal topography and tomography. It’s preferable to have a stable refraction (no increase in myopia more than 0.5 diopter in one year) and this usually occur after 21 years old. You should stop wearing contact lenses for 48 hours before your eye exam and before the LASIK procedure, as contact enses alter the natural shape of your cornea.

As a general rule, myopia up to 10 diopters, astigmatism up to 6 diopters and hyperopia up to 6 diopters can be corrected with LASIK surgery. In some specific case, it might be possible to correct higher errors, but this needs to be evaluated on a case by case basis.

You're having a LASIK, this is what to expect:

  • A full eye examination and a precise evaluation of your refractive error (myopia, hyperopia, astigmatism, presbyopia) will be performed.

    1.

  • Easy to perform, painless and fast exams will be ordered to evaluate the shape of your cornea using specific instruments (topography, tomography, aberrometry, pachymetry, corneal hysteresis). 

    2.

  • Based on the above, your eye surgeon will evaluate your specific need and discuss the best option for your condition

    3.

  • On the day of the surgery, anaesthetic drops are instilled inside your eyes to prevent pain during the procedure. This is called a local anaesthesia. 

    A specific instrument is positioned to keep your eyelids open.

    4.

  • You will be asked to fixate a target light for a short time while the laser is in action.

    The preparation for the surgery takes 15 minutes, while the surgery itself lasts for a few seconds.

    5.

  • After the surgery, you will have a brief eye exam and then you are allowed to go back home.  

    You may feel a temporary burning or itching sensation for 2 to 4 hours. The vision is blurry until the very next morning. You will feel a major improvement by the next day and most patients are able to get back to work one day after the surgery. 

    6.

  • Vision continues to improve within a few days.It is usually recommended to avoid vigorous exercise for 2 weeks.

    You will have an eye exam the day after the surgery, then 3 weeks later.
