ALK uses a device called a microkeratome to separate a thin layer of the cornea and create a flap. [1] The eye is anesthetized and a ring is fixed to it in order to keep it properly positioned and flat. The microkeratome then makes a small incomplete flap across the cornea by cutting across it.
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.
Mast cell stabilizers such as sodium cromoglycate (2%) drops 4–5 times a day are quite effective in controlling VKC, especially atopic ones. Azelastine eyedrops are also effective. Topical antihistamines can be used. Acetyl cysteine (0.5%) used topically has mucolytic properties and is useful in the treatment of early plaque formation.
Superficial lamellar keratoplasty: Superficial lamellar keratoplasty is used to treat superficial corneal opacities, which occupies superficial one third part of stroma. In this technique, the opaque part of the cornea is removed and replaced with donor tissue, leaving healthy part of the cornea including deeper parts of stroma and endothelium.
Corneal transplantation, also known as corneal grafting, is a surgical procedure where a damaged or diseased cornea is replaced by donated corneal tissue (the graft). When the entire cornea is replaced it is known as penetrating keratoplasty and when only part of the cornea is replaced it is known as lamellar keratoplasty.
Photorefractive keratectomy at U.S. Naval Medical Center San Diego. [ edit on Wikidata ] Photorefractive keratectomy ( PRK ) and laser-assisted sub-epithelial keratectomy (or laser epithelial keratomileusis [ 1 ] ) ( LASEK ) are laser eye surgery procedures intended to correct a person's vision, reducing dependency on glasses or contact lenses .
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.
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.
