Laser Vision Correction Procedures
Dr. Orazio L. Giliberti, FACS will help customize and select the best procedure for you, depending on your prescription, the shape of your eye, age, and occupational factors. He personally performs all procedures using an FDA-approved VISX Star S4 IR® Excimer Laser and the WaveScan WaveFront® diagnostic system.
PRK: Photorefractive Keratectomy
Photorefractive Keratectomy (PRK) is an advanced bladeless procedure that is not as invasive as other types of laser vision correction procedures. Instead of making a flap of the corneal tissue using a laser or blade, a brush is used to gently remove the outer layer of cells (epithelium) on the cornea. This will expose the area that the laser will carefully reshape, thereby correcting the corneal imperfections. Upon completion, bandage contact lenses are placed onto the eyes for a few days to protect the cornea while it heals. Clinical studies show that PRK allows for a more architecturally sound corneal structure post-operatively.
epi-LASEK: Laser Epithelial Keratomileusis
Laser Epithelial Keratomileusis (epi-LASEK) is a procedure that is almost a cross between PRK and LASIK. Rather than using a finer blade to cut a flap, a blunt blade is used to remove a thin sheet of epithelial tissue of the cornea. This will expose the area that the laser will carefully reshape, thereby correcting the corneal imperfections. Upon completion, bandage contact lenses are placed onto the eyes for a few days to protect the cornea while it heals.
LASIK: Laser Assisted In Situ Keratomileusis
Laser Assisted In Situ Keratomileusis (LASIK) is a procedure where a laser or blade is used to create a superficial flap of the corneal tissue. Once the flap is lifted, the laser is used to reshape the inner tissue. Upon completion, the flap is put back in place with no stitches required!
No matter which type of procedure is performed, laser vision correction patients should take care during the healing process. Using a shield or sunglasses over the eyes to protect from debris may be beneficial. Also, it is important not to rub your eyes during this time. While patients will notice the improved visual acuity after the surgery, it may take between three to six months for the vision to gradually reach its ultimate quality and clarity.
