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
The lumps appear to be randomly positioned on the cornea and they may appear and disappear over a period of time (with or without treatment). TSPK may affect one or both eyes. When both eyes are affected, the tiny lumps found on the cornea may differ in number between eyes. The severity of the symptoms often vary during the course of the ...
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.
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.

The cornea lacks blood vessels and is among the most densely innervated structures of the human body. Corneal nerves are responsible for maintaining the anatomical and functional integrity of the cornea, conveying tactile, temperature and pain sensations, playing a role in the blink reflex, in wound healing and in the production and secretion of tears.
[11] [14] [9] Corneal transplantation is a management option when there is severe corneal melting or perforation although one possible disadvantage is the risk of rejection. [14] Surgical treatment helps maintain the integrity of the globe, but it is usually complementary because it alone cannot influence the underlying immunological process. [7]
Corneal pachymetry may be useful in confirming the diagnosis. Treatment usually consists of vision correction with eyeglasses or contact lenses. Intacs implants, corneal collagen cross-linking, and corneal transplant surgery are additional options. Surgery is reserved for individuals who do not tolerate contact lenses.
Laser eye surgery or laser corneal surgery is a medical procedure that uses a laser to reshape the surface of the eye to correct myopia (short-sightedness), hypermetropia (long-sightedness), and astigmatism (uneven curvature of the eye's surface). Importantly, refractive surgery is not compatible with everyone, and people may find on occasion ...
