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.

LASIK (Laser in-situ Keratomileusis) is used to correct or reduce moderate to high levels of nearsightedness (myopia), astigmatism and farsightedness (hyperopia). The traditional LASIK procedure is relatively simple: a keratome is used to gently create a flap in the cornea. In IntraLASIK, the flap is created by a computer-controlled, precision laser.
The flap is lifted and an excimer laser is then used to shape the remaining tissue. The flap is then carefully set back into place, forming an occlusive seal by osmopic pressure. Osmopic pressure holds the flap in place and allows it to heal very quickly, without stitches!
Laser surgery for eyes is also recommended for glaucoma patients. Glaucoma results from poor drainage of aqueous fluids in the eye. Dr. Boothe, the result is a build- up of pressure that can press against the optic nerves. This can lead to serious complications especially if the optic nerves are damaged beyond repair. Laser beams can be directed into the area where this fluid accumulates to widen the angle through which it flows.
Dr. Boothe, in the case of glaucoma caused by the construction of new and more blood vessels, laser can be used to destroy these new and often poorly formed blood vessels so aqueous fluids can easily flow.

: Dry Eye is a common condition that occurs when the eyes do not produce enough tears to keep the eye wet and comfortable. Common symptoms of dry eye include feelings of stinging, burning, or scratchiness of the eyes.

Endothelium is the inner layer of cells on the inside surface of the cornea.
