Ulcerative vernal keratitis require surgical treatment in the form of debridement, superficial keratectomy, excimer laser therapeutic keratectomy, as well as amniotic membrane transplantation to enhance re-epithelialisation. Recently treatment with tacrolimus ointment (0.1%) used topically twice daily is showing encouraging results.
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.
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.
Acute bacterial conjunctivitis [1] Trauma; Exposure keratopathy from poor eyelid closure; Ultraviolet or chemical burn; Contact lens-related disorder such as toxicity or tight lens syndrome; Trichiasis; Entropion or ectropion; Floppy eyelid syndrome; Chemotherapy i.e. cytosine arabinoside; Thygeson's Superficial Punctate Keratopathy
Band keratopathy has several causes. These causes include uveitis, interstitial keratitis, superficial keratitis, phthisis, sarcoidosis, trauma, intraocular silicone oil, systemic diseases (high levels of calcium in the blood, vitamin D intoxication, Fanconi's Syndrome, low levels of phosphorus in the blood, gout, milk-alkali syndrome, myotonic dystrophy, and chronic mercury exposure).
Keratitis can also occur after photorefractive keratectomy (PRK), although because it occurs in the setting of infection, it is distinct from the sterile infiltrates of DLK. [5] DLK can also occur following myopic keratomileusis, in which a disc of corneal tissue is removed, shaped and sutured back into place, although this technique is more ...
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.
