LASIK – (Laser Assisted In Situ Keratomileusis)
LASIK first received FDA approval in the 1990’s and quickly grew in popularity until in 2002 it became the world’s most common elective procedure. Since then, LASIK has undergone many advancements. Today’s LASIK is so safe and accurate, it has been approved by the U.S. military for use on their pilots and by NASA for its astronauts. Medical Vision Institute offers Bladeless, All-Laser LASIK to give our Lexington patients the best results possible.
LASIK is performed using an Excimer laser to reshape the cornea to correct vision. It is a fast, virtually painless procedure that takes place right in our Lexington office and offers fast healing and quick results. Before your procedure you will have numbing eye drops applied to your eyes and you may be given an oral medication to help you relax.
The surgeon first creates a thin flap in the outer layer of the cornea using either a microkeratome blade (tradition LASIK) or a femtosecond laser (bladeless, all-laser LASIK). Dr. Dudee then carefully folds back the flap and uses the excimer laser to reshape the corneal tissue underneath. The flap is then carefully folded back into place and serves as a natural bandage. Each eye takes only about 5 minutes. At Medical Vision Institute, we prefer to perform All-Laser LASIK, a blade free form of LASIK.
Immediately following your LASIK procedure you may experience some mild discomfort and blurry vision. You will need to arrange transportation to go home. You will be advised to rest. You eyesight will improve and stabilize within a fewdays. Most patients are amazed when they wake up the next morning and can read their alarm clock without having to reach for their glasses. Almost all patients can drive the following day.
Q: How long has LASIK been performed?
A: LASIK has been performed internationally for approximately 10 years. It was first performed in clinical trials in the U.S. in 1995. Ophthalmologists have been reshaping the cornea for over 50 years, creating a protective layer of tissue for over 35 years, and using the excimer laser since the 1980s.
Q: Who can LASIK benefit?
A: LASIK will benefit those patients with near or farsightedness, or astigmatism. Candidates should have a strong desire to be less dependent on corrective lenses and willing to accept the risks of surgery.
Q: What results can I expect from LASIK?
- At one year after the VISX CustomVue procedure* 100% of the clinical study participants could pass a driving test without glasses or contacts
- 98% of the clinical study participants could see 20/20 or better without glasses or contacts
- 70% of the clinical study participants could see 20/16 or better without glasses or contacts
- Four times as many clinical study participants were very satisfied with their night vision after the VISX CustomVue procedure, compared to their night vision before with glasses or contacts.
Q: Are the results from LASIK permanent?
A: The effects of LASIK are permanent. They do not wear off. But it is important to realize that your eyes can still change internally.
Q: If I have LASIK and my vision changes later in life, can it be redone?
A: Re-treatment may be a solution to changing vision later in life, and other options exist. You need to consult with your doctor to determine which option is best for you.
Q: What type of anesthetic is used for LASIK?
A: The procedure is done with a topical anesthetic (eye drops) to numb the eye. Most patients only feel light pressure during the procedure.
Q: Does LASIK hurt?
A: Because patients are given eye drops to numb the eye, you will experience no pain during the procedure. When Dr. Dudee applies the vacuum ring, the patient experiences a sensation of pressure. The instrument we use to create the flap, and the laser do not cause any pain. For a few hours after the procedure, some patients describe a mild burning sensation, such as after opening the eyes while swimming in chlorinated water. After the first few hours, this feeling usually subsides.
Q: Will I need to wear glasses once my eyes have healed?
A: Most patients do not have to use glasses during their daily life. However, patients over the age of 40 may need to wear glasses for reading. This is caused by the normal aging of the eye that occurs with or without LASIK.
