Would you like to see the world through new eyes, without glasses or contact lenses? Look through our helpful guide below to learn more about the options you have.
Vision correction is possible with LASIK – an outpatient surgical procedure in which a laser is used to reshape the cornea (the surface layer) of your eyes in order to correct how your eyes focus and normalize your vision. It’s also referred to as the “flap and zap” procedure.
LASIK can correct many vision problems, such as nearsightedness, farsightedness, and astigmatism, so that you don’t need to wear eyeglasses or contact lenses in order to see clearly. Besides having improved vision, you will also enjoy your new appearance without glasses!
This guide will explain the benefits of general LASIK methods, what to expect during and after the procedures, and how to decide which one is right for you.
Firstly, you know should if LASIK is right for you or not.
What Eye Conditions does LASIK Treat?
Who’s an Ideal Candidate?
There are 2 general methods to correct your vision – standard LASIK & Epi-LASIK.
What are the Differences between LASIK and Epi-LASIK?
LASIK and epi-LASIK are procedures for improving clarity of vision by using a cold ultraviolet laser beam to reshape the cornea of the eye. The major difference between the procedures is the thickness of the epithelial layer of the cornea that is lifted temporarily to reach the underlying cornea (corneal stroma) for the laser treatment. Other significant differences are listed as follows:
Epi-LASIK VS LASIK
What Can You Expect during LASIK?
In LASIK, anesthetic eye drops are applied. A specialized micro-cutting instrument is used to lift up a thin layer of the surface of the cornea (called a corneal flap or sheet). At the start of the LASIK procedure, you may experience a temporary sensation of pressure and about 20 seconds of “graying out” of vision. Next, a laser makes tiny cuts in the underlying cornea (the corneal stroma). After that, the corneal flap is placed back on top of the cornea. No stitches are required. LASIK takes about 6 minutes.
For a day following LASIK and nightly for 10 nights, a shield is worn over the eye to prevent your accidentally rubbing it. After your vision becomes clear, which can occur in a few days to a few weeks, the procedure is performed on your other eye.
What Can You Expect during Epi-LASIK?
Epi-LASIK can be performed if your cornea is thinner than average and if your work or hobbies put you at risk of the corneal sheet becoming dislodged.
In epi-LASIK, topical anesthetic is applied to the eye. A suction ring is placed around your cornea to keep it from moving. Next, an epithelial separator is used to create a very thin sheet in your corneal epithelium, which is moved sideways. At the start of epi-LASIK, you may feel temporary pressure and 20 seconds of “graying out” of vision. No alcohol solution is applied. The laser reshapes your underlying cornea, and the corneal sheet is put in its original position. No stitches are needed. Epi-LASIK takes about 6 to 10 minutes.
A soft contact lens is placed for protection, comfort, and to speed healing for a few days. After epi-LASIK, your vision in the operated eye typically becomes clear within 3 to 5 weeks. Some people require 3 to 6 months for clarity of vision. Then the epi-LASIK procedure is performed on your other eye.
You can consider Epi-LASIK if the following applies to you:
You can consider LASIK if you fulfill the following criteria:
Most patients achieve 20/20 vision after epi-LASIK or LASIK surgery.
According to clinical studies in Korea and Vietnam in 2012, the effectiveness of epi-LASIK and LASIK surgery is similar. Moreover, the study in Vietnam concluded that epi-LASIK was a safe, predictable and effective alternative to LASIK.
Approximately 95% of patients who underwent LASIK achieved at least 20/20 binocular vision (in both eyes) in 3 months following surgery, according to the Refractive Surgery Alliance in the United States and Europe.
Will You Need an Enhancement Procedure?
After epi-LASIK or LASIK is performed on both eyes, some patients with high initial amounts of nearsightedness, farsightedness, or astigmatism may require an enhancement (a repeat procedure performed 6 to 8 months later) to achieve the right level of vision correction.
The incidence of severe complications is said to be less than 1%. The military has studied this intensively by tracking hundreds of thousands of cases. However, potential side effects include:
Ensure that the following conditions are met:
