Laser Vision Correction has helped millions of people see without glasses and contacts since the initial FDA approval of PRK in 1995. Imagine a lifestyle free  of the hassles of glasses and contact lenses. LASIK, All-Laser LASIK and PRK are the main forms of laser vision correction. Dr. Ronald Gaster is a Beverly Hills and Huntington Beach laser vision correction expert, servicing Los Angeles and Orange County, who can perform these types of vision correction surgeries. With years of credible experience in ophthalmology and clinical research, he is happy to offer his patients the best in laser vision correction.

What are the different types of Laser Vision Correction?

Types of Laser Vision Correction:

What is LASIK?

LASIK (Laser-Assisted In Situ Keratomileusis) is a form of outpatient corneal surgery in which a surgeon uses a specialized and precise flap-making instrument, called a microkeratome, to create a thin flap of corneal tissue with a metal blade. This flap is raised and laid back while still attached to the cornea. The surgeon then uses a state-of-the-art laser to remove a pre-determined amount of corneal tissue from the exposed bed of the cornea.

The amount of tissue to be removed is calculated based on the pre-operative determination of the power of your eye; these measurements are usually in agreement with recent prescriptions for your glasses and/or contact lenses. After the excimer laser treatment the flap is repositioned. Usually, within a few hours, the surface epithelium of the cornea begins to grow over the cut edge of the flap to seal it into position. LASIK can be used to correct near sightedness (myopia), far sightedness (hyperopia), and astigmatism.

What is All-Laser LASIK?

The main difference between traditional LASIK and All-laser LASIK is that the flap that is required for LASIK surgery is created with a Femtosecond laser instead of the traditional microkeratome. This means that the LASIK flap is made with a laser instead of a metal blade. The technology used for All-laser LASIK at Dr. Gaster's practice is the IntraLase method and is a 100% blade-free. The creation of the LASIK flap prepares the eye for the second step of the LASIK procedure, when another (different) laser, known as an excimer laser is used to correct vision. The safety results using IntraLase have been impressive with more patients receiving better and safer results than with a microkeratome blade. The all laser treatment is available at our locations in Beverly Hills & Huntington Beach; serving Los Angeles and Orange County.

PRK (Photorefractive Keratectomy)

PRK is a laser vision correction procedure and is similar to LASIK eye surgery but differs because there is no flap creation as in LASIK. Both PRK and LASIK use the excimer laser to reshape the cornea. PRK shapes the outer surface of the cornea with the laser while LASIK involves creating a flap and treating the inside of the cornea.

For eye surgery patients with irregular corneas, PRK surgery  may be preferred to LASIK eye surgery for the correction of near sightedness (myopia), far sightedness (hyperopia), and/or astigmatism. Unlike LASIK, PRK eye surgery doesn't require an incision in the cornea. For someone with unusually thin corneas, for example, this is a huge advantage since the long-term structural integrity of the eye is not likely to be compromised by PRK surgery.

What Are the Advantages of PRK Eye Surgery?

PRK eye surgery is highly accurate in correcting many cases of near sightedness, far sightedness and astigmatism. Results after 3 to 6 months are essentially equivalent to LASIK in published papers.
