LASIK or Lasik (laser-assisted in situ keratomileusis), commonly referred to as laser eye surgery or laser vision correction, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.

The LASIK surgery is performed by an ophthalmologist who uses a laser or microkeratome to reshape the eye's cornea in order to improve visual acuity.

For most patients, LASIK provides a permanent alternative to eyeglasses or contact lenses.

A contact lens, or simply contact, is a thin lens placed directly on the surface of the eye.

Contact lenses are considered medical devices and can be worn to correct vision, or for cosmetic or therapeutic reasons.

In 2004, it was estimated that 125 million people (2%) use contact lenses worldwide, including 28 to 38 million in the United States.

In 2010, worldwide market for contact lenses was estimated at $6.1 billion, while the US soft lens market was estimated at $2.1 billion.

Multiple analysts estimated that the global market for contact lenses would reach $11.7 billion by 2015., the average age of contact lens wearers globally was 31 years old, and two-thirds of wearers were female.

Optometry is a healthcare profession which involves examining the eyes and applicable visual systems for defects or abnormalities as well as the medical diagnosis and management of eye disease.

Traditionally, the field of optometry began with the primary focus of correcting refractive error through the use of spectacles.

Modern day optometry, however, has evolved through time so that the educational curriculum additionally includes intensive medical training in the diagnosis and management of ocular disease in countries where the profession is established and regulated.

Optometrists (also known as Doctors of Optometry in the US and Canada for those holding the O.D.

degree or Ophthalmic Opticians in the UK) are medical professionals who provide primary eyecare through comprehensive eye examinations to detect and treat various visual abnormalities and eye diseases.

Being a regulated profession, an optometrist's scope of practice may differ depending on the location.

Thus, disorders or diseases detected outside the treatment scope of optometry are referred out to relevant medical professionals for proper care, more commonly to ophthalmologists who are medical doctors that specialize in advanced medical and surgical care of the eye.

Optometrists typically work closely together with other eye care professionals such as ophthalmologists and opticians to deliver quality and efficient eyecare to the general public.
