PRK SURGERY PROCEDURE. On the day of surgery, we advise patients they should plan on being in our office for about 2 hours. This will give the patient time to check-in, have additional testing done if needed, allow time for a mild oral sedative to help relax you, perform the procedure, and then review all post-operative information.
PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. PRK was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. Though PRK recovery takes a bit LASEK and PRK are two different procedures. While both procedures interact with the epithelium atop the cornea, the PRK procedure removes this entirely, while LASEK brushes the material away for the procedure, before being placed back for healing after laser surgery. Sep 27, 2017 · What Is PRK Surgery Recovery Like? Right after surgery, your ophthalmologist will place a “bandage” contact lens over your eye to help it heal. You will need to have someone drive you home after surgery. You should plan to go home and take a nap or just relax after the surgery. Your surgeon may suggest that you take a few days off from work. Nov 16, 2018 · Photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) are both laser surgery techniques used to help improve eyesight. PRK has been around longer, but both are still PRK Surgery is a Type of Laser Vision Correction Photorefractive keratectomy ( PRK ) is a procedure in which the surface of the cornea is reshaped using an excimer laser. This process removes only 5-10% of the thickness of the cornea for mild to moderate myopia - about the thickness of 1 to 3 human hairs. PRK eye surgery was actually developed before LASIK, but both procedures are still in use today. Both PRK and LASIK are focused on reshaping the cornea, which affects how the eye focuses light. The aim of both procedures is to address vision problems like nearsightedness, farsightedness, and astigmatism by gently reshaping the cornea with a laser. Timeline for PRK Recovery . Before surgery: Follow your surgeon’s pre-surgery instructions, and plan to take about a week off work to recover.Although you will get some clarity back in your vision in the first day or so after PRK, you should not strain your eyes for several days, so that means little to no work on the computer, no driving, and little to no reading if possible.
PRK. PRK stands for ‘Photorefractive Keratectomy.’ It is a type of laser vision correction that is an alternative to LASIK for the treatment of near-sightedness, far-sightedness, and astigmatism. Like LASIK, PRK changes the shape of the cornea. The cornea, the clear front window of the eye, is the primary determinant of an eye’s prescription.
PRK Surgery. Both PRK and LASIK use the sophisticated excimer laser to sculpt the stromal layer of the cornea, correcting refractive errors. The sculpting process reshapes the cornea in a way that allows light to properly focus on the retina, resulting in clear vision. PRK surgery involves removing the epithelium with an Amoil’s brush and placement of the laser treatment on the outside surface of the cornea. Key Benefits Corneal tissue sparing Easily enhanced at a later date, even many years later. PRK laser eye surgery (Photorefractive Keratectomy) is a type of laser vision surgery used for the correction of nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. It is an alternative to LASIK, most often recommended if a patient’s corneas are too thin to make LASIK a safe option for them. When patients read about laser vision correction they are presented with a multitude of names, acronyms, and abbreviations. Whether it’s LASIK, iLASIK, intraLASIK, PRK, LASEK, or epi-LASIK, it’s all extremely confusing even for the most enthusiastic patient who is about to undergo this life changing laser eye surgery.

LASIK is also a better option than PRK for correcting more severe nearsightedness (myopia). Laser-assisted subepithelial keratectomy (LASEK). LASEK is similar to LASIK surgery, but the flap is created by using a special cutting device (microkeratome) and exposing the cornea to ethanol.
