    The test maps a patient's cornea for raised areas and surface inconsistencies. LASEK and PRK are two different procedures. While both procedures interact with the epithelium atop the cornea, the PRK procedure removes this entirely, while LASEK brushes the material away for the procedure, before being placed back for healing after laser surgery.

    en.wikipedia.org/wiki/Phototherapeutic_keratectomy

    Phototherapeutic keratectomy (PTK) is a type of eye surgery that uses a laser to treat various ocular disorders by removing tissue from the cornea. PTK allows the removal of superficial corneal opacities and surface irregularities. It is similar to photorefractive keratectomy, which is used for the treatment of refractive conditions.

    Keratoconus, a progressive thinning of the cornea, is a common corneal disorder. Keratoconus occurring after refractive surgery is called Corneal Ectasia. It is believed that additional thinning of the cornea via refractive surgery may contribute to advancement of the disease [31] that may lead to the need for a corneal transplant.

    Maximilian Salzmann (9 December 1862, in Vienna – 17 April 1954, in Graz) was an Austrian ophthalmologist. In 1887 he received his medical doctorate from the University of Vienna , where he later worked as an assistant to Ernst Fuchs at the eye hospital.

  6. Radial keratotomy - Wikipedia

    en.wikipedia.org/wiki/Radial_keratotomy

    The healing corneal wounds consist of newly abutting corneal stroma, fibroblastic cells, and irregular fibrous connective tissue. Closer to the wound surface lies the epithelial plug, a bed of the cells that form the normal corneal epithelium which have fallen into the wound. Often this plug is three to four times as deep as the normal corneal ...

  7. Keratomileusis - Wikipedia

    en.wikipedia.org/wiki/Keratomileusis

    Keratomileusis, from Greek κέρας (kéras: horn) and σμίλευσις (smíleusis: carving), [1] or corneal reshaping, is the improvement of the refractive state of the cornea by surgically reshaping it. It is the most common form of refractive surgery.

    Peter S. Hersh is an American ophthalmologist, researcher, and specialist in LASIK eye surgery, keratoconus, and diseases of the cornea.He co-authored the article in the journal Ophthalmology that presented the results of the study that led to the first approval by the U.S. Food and Drug Administration (FDA) of the excimer laser for the correction of nearsightedness in the United States.

  9. Photodisruption - Wikipedia

    en.wikipedia.org/wiki/Photodisruption

    When used in corneal surgery, picosecond and nanosecond disruptors are used on the lamellae of the corneal stroma, and the method may be preferable as it leaves the epithelium and Bowman's layer unharmed. This modifies the outer corneal curvature, which affects the refractive property of the eye.
