Osteo-odonto-keratoprosthesis (OOKP), also known as "tooth in eye" surgery, [1] is a medical procedure to restore vision in the most severe cases of corneal and ocular surface patients. It includes removal of a tooth from the patient or a donor. [2]
Corneal cross-linking (CXL) with riboflavin (vitamin B 2) and UV-A light is a surgical treatment for corneal ectasia such as keratoconus, [2] PMD, and post-LASIK ectasia. It is used in an attempt to make the cornea stronger. According to a 2015 Cochrane review, there is insufficient evidence to determine if it is useful in keratoconus. [3]
Treatment of patients whose vision is less than 20/200 in the affected eye. Patients with failed corneal transplant using donor cornea and have little or no vision left. Patients with non-autoimmune diseases, congenital birth defects and other ocular problems. Patients who do not have access to corneal transplant tissue
Treatment options include contact lenses and intrastromal corneal ring segments for correcting refractive errors caused by irregular corneal surface, [7] [8] corneal collagen cross-linking to strengthen a weak and ectatic cornea, [9] or corneal transplant for advanced cases.
Epikeratophakia [1] (also known as epikeratoplasty and onlay lamellar keratoplasty [2]) is a refractive surgical procedure in which a lamella of a donor cornea is transplanted onto the anterior surface of the patient's cornea. A lamellar disc from a donor cornea is placed over the de-epithelialized host cornea and sutured into a prepared groove ...
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 .
A Gundersen flap, also known as Gundersen's flap, Gundersen's conjunctival flap, or conjunctivoplasty, and often misspelled Gunderson, is a surgical procedure for correcting corneal disease. It involves excising a damaged section of cornea, and replacing it with a section (or "flap") of the patient's own conjunctiva. [1]
Recurrent corneal erosion (RCE) is a disorder of the eyes characterized by the failure of the cornea's outermost layer of epithelial cells to attach to the underlying basement membrane (Bowman's layer). The condition is excruciatingly painful because the loss of these cells results in the exposure of sensitive corneal nerves.
