PRK and LASIK are very similar. LASIK has a tiny blade that cuts the cornea. On the other hand, PRK doesn't do this. PRK uses a laser to reshape the cornea without cutting it.

How is PRK different than Lasik eye surgery?
There are a few differences between PRK and Lasik eye surgery. PRK was the first laser surgery used to correct vision. The main difference between the two is that it usually takes longer to recover from PRK surgery. With Lasik surgery a small hinged flap is made on the cornea, and with PRK the entire surface of the cornea is removed and therefore takes longer to recover.
What kinds of vision problems can be corrected by LASIK surgery and by PRK surgery?
Nearsightedness, farsightedness, and astigmatism can be corrected using LASIK or PRK.
Which is better and more cost effective, PRK or Lasik eye surgery?
The cost difference on the two surgeries is not much depending on what type of surgery you need for your eye. The difference between the two is that the PRK is more uncomfortable and takes a lot longer for results where the Lakik the difference is almost right away. PRK was invented first but Lasik is much more popular.
What is the difference between Lasik and PRK?
LASIK and PRK are both laser procedures that correct nearsightedness, farsightedness, astigmatism and presbyopia. The main difference between the two is the following: LASIK uses a microtome knife or laser to create a flap followed by use of an Eximer laser to ablate the corneal tissues. PRK, on the other hand, uses a sterile brush or laser to scrape away the surface corneal epithelial cells, followed by use an Excimer laser to ablate and reshape the corneal tissue. Although PRK takes longer to heal and produces more discomfort than LASIK, it is an ideal surgery for patients with thin corneas and large pupils.

What are facts about PRK laser?
PRK Laser Eye Surgery is a type of refractive surgery. PRK reshapes the cornea using an excimer laser. Unline LASIK, in PRK, the cornea's entire outer layer is removed and no flap is created. However, recovery from PRK is a little longer than recovery from LASIK.
How many people have follow up surgery after LASIK?
About 5-10% of PRK patients return for an adjustment, as do 10-25% of LASIK patients.

Comparing Lasik And Prk Laser Eye Surgeries?
A desire to end dependence on eyeglasses and contact lenses for vision correction draws more and more people to laser eye surgery. Knowing which surgeries are available, how they differ and what to expect can help determine the most compatible one. PRK PRK, or photorefractive keratectomy, the first U.S. government-approved laser eye surgery to correct nearsightedness, farsightedness and astigmatism, uses a cool ultraviolet laser to reshape the eye by removing some of the tissue from the cornea or eye covering. Changing the eye shape allows light to focus properly on the retina and leads to improved vision. LASIK Laser-Assisted In Situ Keratomileusis surgery, accomplishes the same results as PRK by a different method. Unlike PRK, LASIK surgery creates a corneal flap before the laser procedure takes place. Patients undergoing either surgery remain awake during the full procedure, which takes about 15 minutes per eye. Pros and Cons Less discomfort and shorter recovery time have made LASIK more popular. LASIK patients often see an instant difference in vision, returning to work the day after surgery, while PRK patients may wait days or weeks for full effects. Post-surgical light sensitivity, blurred vision and eye infections are more common with PRK. Patients with thin corneas, previous refractive procedures and cataract surgery may be better PRK candidates. Eye surgeons recommend PRK for patients with large pupils, dry eyes, certain medical conditions and injury-prone lifestyle choices like kickboxing. Candidacy and Results Being a good candidate for PRK or LASIK surgery starts with a thorough eye exam conducted by a qualified eye surgeon. Extensive testing includes a corneal topography or mapping and multiple, painless exams like a pupillometry and Shirmer test. Medical history, age and expectations are all evaluated. Vision correction surgery can result in 20/20 vision; however, sometimes almost-perfect 20/40 is the most achievable result. Some patients must continue to wear eyeglasses or contacts after surgery. At present, there is no approved laser vision correction for presbyopia, an over-age-40 condition that requires the use of reading glasses. Costs Some health insurances have partial laser eye surgery coverage, but most still consider it elective. Some surgeons, sensitive to patients' out-of-pocket expenses, offer financing programs. Quotes for laser eye surgery are made per eye and may include extra charges if new technologies like wavefront analysis are needed. In a 2010 refractive surgeon survey, the average cost of laser eye surgery fell between $1,580 and $2,170 per eye.

What Makes The PRK LASIK Procedure The Best Choice?
When looking into a procedure that will fix your vision, you have two basic choices. You can either get a PRK LASIK procedure, or you can get the standard LASIK procedure that many people use. You may have heard of this procedure before, but you probably do not know that the PRK technique is actually older. It was approved by the government for use before the standard LASIK procedure. In many ways, it is actually a better option. You should read the following and consider this before you go in to have the surgery carried out. The main reason that people prefer PRK is that no corneal flap has to be created. This is what has to be done in a LASIK procedure, and it can lead to complications. If an error is made when the flap is being created, there could be problems with the healing process or the success of the surgery. You could have to go in to have the mistake corrected. Since creating the flap adds another step to the process, there is also just a greater chance that the surgeon will make a mistake while performing this operation. The less steps there are, the better the odds that nothing will go wrong. What this also means is that this type of surgery can be performed on those who have a thinner cornea. All eyes are different, so this has been something of a problem with the LASIK procedures. Those who have thin corneas cannot get the surgery because there is not enough room to make a flap on the thin cornea. When using the PRK tactic, this is not an issue. Anyone can get this procedure done because the laser surgery without a flap can be done on a cornea of any thickness. The downside of the PRK procedure is that it does take a bit longer to recover after it is done. This means that you will have more time during which you cannot go to work. It will be a bit more of an inconvenience to you since you will not be able to adjust to your life as quickly. However, this is a small price to pay to make sure that nothing goes wrong and that there are no complications. After all, it will take you much longer to recover if you choose the LASIK procedure and an error is made by the surgeon.
