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.
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.
Large vernal plaque requires surgical excision. 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.
Photorefractive keratectomy (PRK) is an outpatient procedure generally performed with local anesthetic eye drops (as with LASIK/LASEK). It is a type of refractive surgery which reshapes the cornea by removing microscopic amounts of tissue from the corneal stroma, using a computer-controlled beam of light ( excimer laser ).
Blepharoplasty (eyelift) is plastic surgery of the eyelids to remove excessive skin or subcutaneous fat. [31] East Asian blepharoplasty, also known as double eyelid surgery, is used to create a double eyelid crease for patients who have a single crease (monolid).

Incisions that penetrate only the superficial corneal stroma are less effective than those reaching deep into the cornea, [3] and consequently, incisions are made quite deep. One study cites incisions made to a depth equivalent to the thinnest of four corneal-thickness measurements made near the center of the cornea. [ 4 ]
A form of laser eye surgery named keratectomy may help with the superficial corneal scarring. In more severe cases, a partial or complete corneal transplantation may be considered. [ 3 ] However, it is common for the dystrophy to recur within the grafted tissue.
In severe cases, surgery may be required due to excessive corneal scarring such as superficial keratectomy (SK), phototherapeutic keratectomy (PTK), lamellar keratoplasty, or penetrating keratoplasty. [1] Patients may relapse in symptoms but surgery prolongs the reoccurrence and may also lessen severity. [1]
