Macular Dystrophy - A hereditary type of macular degeneration. In a normal eye, the macula, the central part of the retina, has specialized cells that detect light and color. Macular Dystrophy is a deterioration of these cells so that we see less and less clearly. It is the most severe of the three main Stromal Dystrophies, but the least common.

Laser Thermal Keratoplasty (LTK) - (KER-uh-tuh-PLAS-tee) LTK is a refractive surgery treatment for mild farsightedness. A Holmium laser is used to gently and precisely heat a circular area around the edge of the cornea, so that this edge shrinks a little. The result is a steepening of the cornea, which in farsightedness is too flat. It’s also used to treat presbyopia.

DALLAS LASIK - DR WILLIAM A. BOOTHE: Diffuse Lamellar Keratitis (DLK) - Also known as Sands of Sahara. A rare complication of LASIK surgery, appearing between 2 and 5 days after surgery, where inflammation develops between the corneal flap and the corneal tissue beneath it. The cause isn’t certain. It causes blurriness of vision when it’s severe enough.

Various measures are usually taken to prevent it, such as use of sterile tape to keep the eyelashes away from the treatment area, rinsing the cornea before making the flap, and rinsing again before replacing the flap. After surgery, medicated eyedrops are typically used to prevent inflammation. DLK needs to be detected promptly so that it won’t impair vision. Usually it responds well to use of corticosteroid eyedrops and sometimes the surgeon will lift the flap again to rinse beneath it.

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.

LASIK EYE - DR WILLIAM BOOTHE: Basement Membrane - A microscopically thin layer of tissue below the epithelial cells (surface cells) of the cornea, connecting those cells to the stroma, which is the middle layer of cells in the cornea.

Best Corrected Visual Acuity - A measurement of your best vision, as corrected by your glasses or contact lenses.

Bifocals - The type of glasses we usually call “reading glasses”, where most of the lens corrects your distance vision, and a small area at the lower edge of the lens corrects your close-up vision. They’re used by people with presbyopia. There are also trifocals.

It's as if the refraction is "ground in" to the middle layers of the cornea! The results are often dramatic and very rapid, with most patients seeing well enough to drive a car without correction the very next day. However, the best post-operative visual acuity may not be obtained until 2 to 3 weeks, or in some cases, even a few months, after the procedure.

Regression - Return of the cornea after PRK or LASIK to its original refractive error. Post-surgical healing happens on both the surface (epithelium) where the flap was created and in the stroma (next level down, treated by the laser), and these two layers heal at slightly different rates. The planned treatment is designed to slightly overcorrect the refractive error so that after healing, the eye will have no refractive error. But some patients heal more quickly and vigorously than was expected, so that the cornea restores itself back to its original shape, and this is known as regression. See also undercorrection.
