Ablation

Surgical removal. In vision correction surgery, ablation refers to the removal of corneal tissue to correct a refractive error like nearsightedness or farsightedness.

Accommodation

Ability of the eye to change focus while looking at objects at varying distances.

Astigmatism

Condition in which one of the eyes' refractive surfaces has an irregular shape (not spherical), causing visual distortion.

CK (Conductive Keratoplasty)

Refractive surgery procedure that reshapes the cornea using radio waves. CK is used to treat hyperopia and presbyopia.

Cornea

Transparent outer covering of the eye that allows light to enter and helps the eye focus.

Excimer laser

Surgical equipment that produces a thin, powerful beam of ultraviolet light. An excimer laser is used to remove microscopic layers of tissue from the cornea to enhance vision.

Farsightedness (Hyperopia)

Visual defect that causes difficulty viewing near objects, while distant objects are easily focused on.

Higher-order Aberration

Visual imperfections other than refractive errors (farsightedness, nearsightedness, and astigmatism).

LASEK (Laser Epithelial Keratomileusis)

Vision correction procedure that uses a laser to reshape the cornea's inner layers. LASEK laser eye surgery may be appropriate for individuals who are not candidates for LASIK due to thin corneas.

LASIK (Laser-Assisted In-Situ Keratomileusis)

Vision correction procedure that uses a laser to reshape the cornea's inner layers, improving nearsightedness, farsightedness, astigmatism, and other visual imperfections.

Nearsightedness (Myopia)

Visual defect that causes blurred distance vision.

Pachymetry

Procedure used to measure the thickness of the cornea.

Presbyopia

Condition that causes difficulty focusing on near objects due to a lack of elasticity in the eye's cornea and lens associated with aging.

PRK (Photorefractive Keratectomy)

Vision correction procedure that uses a laser to reshape the surface of the cornea, improving nearsightedness, farsightedness, and astigmatism.

Topography

Procedure used to map the surface of the cornea.
