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.

Cataract surgery is the most common application of lens removal surgery, and is usually associated with lens replacement. It is used to remove the natural lens of the eye when it has developed a cataract, a cloudy area in the lens that causes visual impairment. [4] [10] Cataracts usually develop slowly and can affect one or both eyes. [4]
Manual small incision cataract surgery (MSICS) is an evolution of extracapsular cataract extraction (ECCE); the lens is removed from the eye through a self-sealing scleral tunnel wound. A well-constructed scleral tunnel is held closed by internal pressure, is watertight, and does not require suturing.
Refractive surgery aims to correct errors of refraction in the eye, reducing or eliminating the need for corrective lenses. Keratomileusis is a method of reshaping the corneal surface to change its optical power. A disc of the cornea is shaved off, quickly frozen, lathe-ground, then returned to its original power. Automated lamellar keratoplasty
The removal of cataracts by surgery was introduced into China from India, and flourished in the Sui (581–618 CE) and Tang (618–907 CE) dynasties. [ 17 ] The first references to cataract and its treatment in Europe are found in 29 CE in De Medicina , a medical treatise by Latin encyclopedist Aulus Cornelius Celsus , which describes a ...
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.
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 .
Conjunctival concretions can be seen easily by everting the eyelid. The projecting concretions can be removed if they are causing concerning symptoms. Removal can be performed by an eye doctor. Sometimes just a needle or a scalpel is used to remove the concretion under local light anesthesia of the conjunctiva in adults.
