    By patriciajacobs | News | Comments are Closed | 20 January, 2020 | 0


    LASIK commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.
    The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye’s cornea in order to improve visual acuity.
    For most people, LASIK provides a long-lasting alternative to eyeglasses or contact lenses.

    The laser will removed some microns of the cornea according to the pre-operation refraction and post refraction target.
    The treatment zone is  shown in dark.
    Centration of the treatment should be important
    The white circle have  always the following diameter : 3/5/7 mm

    Cornea thickness decrease in the treatment zone. Laser will remove between 9-13 microns for 1 diopter.

    The treatment zone is  shown in dark. You could also see the pupil boundary: here in between the 3 to 5 mm white circle.

    Cornea thickness decrease in the treatment zone.
