Dr William Boothe

One may experience increased sensitivity to light and some blurring of vision but these are normal and will clear up in a matter of 3-4 days. Doctors often give eye drops or oral medication to prevent infection and to counter some minor side-effects. Recovery is also quick and the person can resume normal activities after 4-5 days.
Eyeglasses - Fashion Accessories For Your Face - Dr William Boothe Laser Surgery for Your Eyes - Dr William Boothe DR WILLIAM BOOTHEHaving problems with vision and having to wear eyeglasses or contact lenses can be burdensome. Some have problems with constantly losing or breaking glasses and tearing contact lenses. Some find it difficult to look for glasses that perfectly fit the shape of their faces and some feel that it makes them look older.

regression - A return to the original refractive state. In PRK the surface layer or epithelium is removed prior to or as part of the procedure and then the deeper corneal stroma is reshaped with the cold laser treatment. During healing both the surface epithelium and the deeper corneal stroma can reshape and reform at different rates. Computer generated PRK treatments assume a normal "Bell" curve amount of healing for both layers and thus normally "over correct" the refractive error in order to finally heal with no refractive error and no need for glasses. A small percentage of patients will heal faster and more vigorously than expected and will thus regress or "heal" their planned over correction back past no refractive error to their original type of error. This regression phenomenon occurs with both myopic and hyperopic corrections. It occurs more commonly with smaller ablation diameters and with abrupt transition zones at the edge of the laser treatment areas. Some surgeons have suggested that the epithelium overgrows as if nature abhors a vacuum and overreacts to fill in the space. Steroid medications can usually be used to regulate and control regression.

William Boothe: Keratotomy is a surgical incision (cut) of the cornea.

Keratitis is the inflammation of the cornea.

Kerato is the prefix indicating relationship to the cornea.

Manifest Refraction - The eye examination which determines a person’s degree of refractive error. The patient looks through a phoropter, an instrument with an array of lenses, at the eye chart set first at 20 feet away (for distance vision), then at 16 inches away (for near vision). The optometrist or ophthalmologist changes lenses and asks which ones give the clearest image.

William Boothe Dallas: Flying Spot - A method of applying the excimer laser light used in refractive surgery. A flying spot laser is used, which has a 1mm - 2mm diameter light beam. The computer that controls the laser is programmed to send pulses to changing spots on the cornea, with no spots overlapping. Part of the ophthalmic laser system is an eye tracker, which responds to all eye movement during surgery. So even if the eye moves while it’s being treated, the entire targeted area will be treated, because the treatment plan has determined where the laser should shine, in the series of flying spots that will cover it entirely, and the whole system moves to correspond with any eye movements during surgery.

Flying spot lasers can be used in both traditional LASIK procedures and those using wavefront technology.

Why is it so popular? LASIK has advantages over other procedures, including a relative lack of pain afterward and the fact that good vision is usually achieved by the very next day. Dr. Boothe, an instrument called a microkeratome is used in LASIK eye surgery to create a thin, circular flap in the cornea. Another, newer way of making the flap is with a laser.
Dr Boothe Lasik Surgeon A pioneer in the field of refractive surgery, Dr. William Boothe was one of the first cornea specialists to be trained in vision correction techniques during his Fellowship. In addition, he was the first cornea-trained surgeon in the Dallas area to use an FDA-approved Excimer laser for refractive surgery.

PTK - Photo Therapeutic Keratectomy "Cold" laser removal of surface tissue of the cornea such as scar tissue for medical or optical treatment reasons.

ptygeria - A growth of scar tissue on the cornea. These lesions like pinguecula are caused by an ultraviolet burn to the surface layer or epithelium.

radial keratotomy - A surgical operation where 90% thickness cuts are made in the cornea. These cuts are made in a radial fashion and spare the visual center of the cornea. The intention is to flatten the central cornea.

Aqueous Humor - (AY-kwee-us) The clear fluid that nourishes the lens and the cornea, flowing between them, secreted by the ciliary processes.
ASCRS - American Society of Cataract and Refractive Surgery, a professional membership organization for ophthalmologists who perform cataract and refractive surgeries.

Wavefront Supported Corneal Ablation - The trade name for the Carl Zeiss Meditec WASCA aberrometer and the MEL 70 or MEL 80 excimer laser system when it’s used for wavefront guided excimer laser ablation for Lasik, Epi-Lasik, LASEK, PRK, and IntraLasik.

Coma - A higher order aberration which makes points of light look like comets with blurry tail-like smudges. It can be diagnosed and treated with wavefront-guided LASIK procedures.

Complex Wavefront Retreatment - An off-label use of the excimer laser to do corrective secondary surgery after the original wavefront-guided surgery has left the patient with higher-order aberrations.

Dr William Boothe Surgeon: diopter - The diopter is the unit of measurement for optical lenses. A one diopter lens will focus parallel light rays 1 meter from the lens and a two diopter lens will focus 0.5 meter from the lens. A plus ( + ) 1.0 diopter lens is convex and will converge the light rays so they focus as a visible image 1 meter past the lens. A minus ( - ) 1.0 diopter lens is concave and will diverge or spread light. The minus lens will not actually focus as a visible image on an optics table. Its image is known as a virtual image and if the divergings rays were followed to their point of origin they would focus 1 meter in front of the minus lens.

Myopia the inability to see distant objects clearly.

Nearsightedness is the common term for myopia.

Ophthalmologist is a medical doctor specializing in the diagnosis and medical or surgical treatment of visual disorders and eye disease.

Dr Boothe: ICL (Implantable Contact Lens) - The name used for the STAAR Myopic Visian ICL™, created by the STAAR Surgical Company and approved by the FDA in 2005 for treating myopia. It’s a refractive lens for use in a phakic eye (i.e., an eye that has its natural crystalline lens intact) and is implanted in the posterior chamber of the eye.

Inflammation is a tissue’s reaction to trauma often associated with pain, heat, redness, swelling, and/or loss of function. Inflammation may be caused by mechanical trauma,infections, bacteria, viruses, immune reactions or other causes.Ophthalmologist is a medical doctor specializing in the diagnosis and medical or surgical treatment of visual disorders and eye disease.
Intraocular Pressure - The pressure within the eye is determined by how much aqueous fluid is created and drained inside the eye. An increase in intraocular pressure can put pressure on the optic nerve, causing serious vision problems. The intraocular pressure is measured with a tonometer.
Wavefront - Technology used to detect and measure higher order visual aberrations. These are the ocular aberrations other than the lower order aberrations of myopia, hyperopia, and astigmatism, which can be detected by a traditional eye examination. Some examples are glare, halos, and starbursts.

Dr Boothe

Focusing power of the eye - The combined action of the cornea and the lens to refract light on to the retina. As light enters the eye, it’s refracted (bent) by the cornea, because of the cornea’s curvature. As the light continues further into the eye, passing through the pupil to reach the lens, it’s refracted more, to a variable degree according to how far away from the eye the object is which is reflecting this light. If it’s down the road a ways, like a distant traffic light, it needs to be refracted less in order to land in focus on the retina. If it’s close up, like the clock on the dashboard, it needs to be refracted more.

Dr William Boothe

Secondary Implant - In some cataract surgeries, the crystalline lens is not replaced. It can be replaced later with an intraocular lens, in a secondary implant procedure.
