Top 6 Laser Eye Surgery Methods
Gone are the days of having to worry about where you put your glasses or if you remembered to purchase saline solution for your contact lenses. With the numerous laser eye surgeries available, you can rest assured that one is perfect to fix your eyesight. If you are seeking laser eye surgery to correct your faulty vision, you are one of many who are taking advantage of such high tech surgeries. Take a look at the top 6 laser eye surgery methods to learn what options are available.
1. Photo Refractive Keratectomy (PRK)-This type of laser surgery is for those who are nearsighted due to either the curvature of the cornea or the eyeball being too long. The laser in this procedure slices off a thin layer (removes) from the cornea by removing tissue from the cornea in precise amounts. It essentially flattens the cornea out. PRK just takes a couple of minutes and is done in the office with eye drops that give a local anesthetic. Recovery time is one to two days.
2. Laser-Assisted In Situ Keratomileusis (LASIK)- This type of laser surgery is for those who are severely near or farsighted. The procedure combines both laser and surgery to reshape or flatten the cornea. The surgeon carefully makes an incision in the cornea to make a flap, uses a laser to reshape the cornea, and then the flap heals over the layer. This type of surgery may be bit more complex in nature than PRK, but it has less recovery time.
3. Laser Epithelial Keratomileusis (LASEK)- This type of surgery combines LASIK and PRK procedures to treat near and farsightedness, as well as astigmatism. The difference between LASEK and LASIK is that in LASEK surgery, the epithelium is not cut with the same cutting tool as LASIK, but with an atrephine, which has a finer blade. The recovery time is longer for LASEK with patients taking one to two weeks to heal.
4. Epi-Lasik- This type of eye surgery is newer than LASIK and LASEK, and is designed to have less complications. Just like in LASEK surgery where the epithelium, or the cornea’s outer layer, Epi-Lasik does the same but with a different instrument- a blunt, plastic oscillating blade. Epi-Lasik also refrains from using alcohol to loosen the epithelial sheet and instead uses an epithelial separator to separate the eye from the sheet.
5. Super Lasik- This is a newer type of eye surgery and is considered safer than many of the other ones. Combining some aspects from both the PRK and LASIK, Super Lasik involves the use of an Epikeratome, which is an instrument approved by the FDA that raises about 50 micron flap to make it very thin.
6. Femto-Lasik- This type of eye surgery is similar to LASIK, but makes the corneal flap with a femtosecond laser microkeratome instead of the microkeratome.
With such new and useful laser eye surgeries to choose from, those that do not want to wear glasses or contact lenses anymore can be well on their way. Discuss the different eye surgeries with your surgeon to make the right decision for you.
