Los Angeles Laser Eye Surgery - Lasik Eye Procedure Glossary of Terms.Ablate - in a lasik eye surgery procedure this is known as to "remove". Ablation zone - the tissue removed from an area during a laser surgery. Accommodation - when the eye is able to change focus on a distant object to a near object. Acuity - how sharp and clear the vision of what you are focusing on with your eye. All-Laser LASIK - (commonly know as the “Bladeless LASIK”) a keratome laser device is implemented to make an incision on the corneal flap of your LASIK eye surgery procedure. Astigmatism - an image that is distorted from the retina cause by the cornea or lens of your eyes. Cornea - the first part of your eye that is clear is called the cornea. The clear first layer of your eye is where the light bends or refracts and this is where the focusing of your eye occurs. Diopter - this is where refractive error is measured by the surgeon. A negative diopter means that that the value of the eye has myopia and when it is positive it means hyperopia. Dry Eye Syndrome - this happens often when the eye cannot product enough natural tears to keep the eye comfortable with moisture. Endothelium - the layer inside the cells of the outside surface of your cornea. Epithelium - this layer provides a protection against infection which is located on the outer layer of the cornea. Excimer laser - a ultraviolet laser is used in a refractive laser eye surgery to remove the corneal part of the tissue. Farsightedness - this is what is commonly known as "hyperopia". FDA - Food and Drug Administration. This is a goverment agency responsible for approval of medical products and procedures in the lasik eye surgery field. Flap & Zap - this term is commonly used as a slang to LASIK eye surgery procedure. Ghost Image - a fainter second image of the object you are viewing. when you are viewing an image and it is faint second image this is called a ghost image. Glare - this occurs when bright light decreases your vision. Halos - rings are lights that occur when there are imperfections in or infront of your eye. Haze - corneal clouding that causes the sensation of looking through smoke or fog. Hyperopia - difficult or not being able to clealy see close objects vs seeing objects clearly at a distance. Informed Consent Form - this forms lays out providing the client with the risks and benefits of the lasik eye procedure. Also included will be alternatives to the laser eye surgery procedure. In Situ - this is a Latin term meaning "in the place" or not to be removed. Iris - the tissue that is ring colored sitting behind the cornea and directly infront of the lens Keratectomy - the surgery procedure in which the corneal tissue is removed. Keratotomy - a surgery procedure where an incision is made on the cornea. Keratitis - when the corean has inflammation occuring. Kerato - this is a prefix showing the relationship of the cornea. Keratoconus having irregular corneal surface is characterized by having blurred and not clear vision. Keratomileusis - this means reshaping and carving the cornea. Laser - a laser is an instrument used in laser eye surgery procedures in which a light is used to stimulate emission of radiation. This powerful laser can help remove certain tissues of the eye. Laser Keratome - creating a corneal flap using a laser keratome. Lens - this is part of the eye that allows for focusing. The lens is typically reshaped to allow for focusing and all different distances. Microkeratome - this is a surgical device that attached to the patients eye by using a vacuum ring. Once this is secured a blade then cuts a thin layer of the cornea. Monovision - if the patient has near vision this is used to make adjustments. Myopia - unable to see objects in the distance vs seeing objects that are close in clear vision. Nearsightedness - also known as "myopia". Overcorrection - this type of complication occurs when a refractive surgery is done more than the correction amount PRK - this term is also known as photorefractive keratectomy where the surgeon removes the top layer of the cornea and uses a computer to control the reshaping of the eye. Presbyopia - when difficulty occurs when trying to focus on a clean image as it gets closer. Pupil - this is where the iris has a hole in the cetner and changes in size depending on the lighting condition for the eye. Radial Keratotomy - this lasik eye surgery procedure is used to fix the myopia by compressing the cornea by using the radial cuts. Refraction - this test is implemented to find out the refractive power of the clients eye. Refractive Errors - finding imperfections in the actual focusing power of the clients eyes. Refractive Power - finding the ability of clients eyes to reflect light as it passes through. Retina - the retina is a sensory tissue that is lined by the inside wall of the eye. the retina provides a way to a capture the images and send that image to the brain. Sclera - provides protection the eyeball by providing a thich tough white outer layer for the eyeball. Snellen Visual Acuity Chart - this is a chart used to guage the clients vision. Stroma - this is the thickest part of the tissue located in the cornea. Undercorrection - this type of complication occurs when the surgery provided by LASIK is under the amount of what the correction was desired. Visual Acuity - this is the actual clarity of the vision to show detail and shape of an object. Vitreous Humor - a gel that sits behind the lens and directly infront of the retina that fills the middle of the eyeball. Wavefront - this technique measures the refractive amount of error that cannot be fixed with glasses or contacts.  |
