  2. Photorefractive keratectomy - Wikipedia

    en.wikipedia.org/wiki/Photorefractive_keratectomy

    With PRK, the corneal epithelium is removed and discarded, allowing the cells to regenerate after the surgery. The procedure is distinct from LASIK (laser-assisted in-situ keratomileusis), a form of laser eye surgery where a permanent flap is created in the deeper layers of the cornea. However, PRK takes longer to heal and can, initially, cause ...

  3. LASIK - Wikipedia

    en.wikipedia.org/wiki/LASIK

    LASIK surgery is performed by an ophthalmologist who uses a femtosecond laser or a microkeratome to create a corneal flap to expose the corneal stroma and then an excimer laser to reshape the corneal stroma in order to improve visual acuity. [2] [3] LASIK is very similar to another surgical corrective procedure, photorefractive keratectomy (PRK ...

    Between 95% and 98% of Laser Blended Vision patients can read normal newsprint and between 80% and 96% can read the very smallest print on medicine bottle inserts (J1 or N4 print size)., [4] [5] There is a creation of intermediate and far-intermediate distance zone of binocular fusion, allowing the merging of images from each eye in the brain ...

    en.wikipedia.org/wiki/Refractive_surgery

    Refractive surgery is an optional eye surgery used to improve the refractive state of the eye and decrease or eliminate dependency on glasses or contact lenses. This can include various methods of surgical remodeling of the cornea ( keratomileusis ), lens implantation or lens replacement.

  7. Munnerlyn Formula - Wikipedia

    en.wikipedia.org/wiki/Munnerlyn_Formula

    The Munnerlyn Formula is the theoretical formula [1] discovered by Charles Munnerlyn which gives the depth an excimer laser will need to ablate during LASIK surgery or similar medical interventions. The formula states that the depth of the ablation (in micrometres) per diopter of refractive change is equal to the square of the diameter of the ...
