LASIK

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:

  • LASIK eye surgery
  • All-Laser LASIK (bladeless) surgery
  • PRK (Photorefractive Keratectomy)

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 nearsightedness (myopia), farsightedness (hyperopia), and astigmatism.

1. The flap is created, then raised and laid back while still attached to the cornea. 2. The surgeon then uses a state-of-the-art laser to remove a predetermined amount of corneal tissue from the exposed bed of the cornea. 3. After the excimer laser treatment the flap is repositioned.

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.

Vince J.

“I’d wanted corrective eye surgery for years and had consulted with another physician before meeting with Dr. Gaster. Unlike the other doctor, whose consultation felt more like a sales pitch than a medical doctor exam, Dr. Gaster and his staff took their time and did a thorough examination of my eyes and my vision. And, most importantly, Dr. Gaster discovered that my corneas were too thin for the procedure that the other doctor tried to convince me to have. And in my case, as opposed to doing both eyes, he suggested that I could better achieve my goals by simply doing one (saving my vision and saving me money). When he told me that I knew I was in great hands.

The surgery went like clockwork, from prep to the post-op follow up call to see how I was doing. And of course, Dr. Gaster’s work was excellent.

I could not be more pleased!”

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 nearsightedness (myopia), farsightedness (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 nearsightedness, farsightedness, and astigmatism. Results after 3 to 6 months are essentially equivalent to LASIK in published papers.

What are the Disadvantages of PRK Eye Surgery?

Mild to moderate discomfort, including eye irritation and watering, for one to three days following the procedure. Typically patients are 80% corrected at one month after surgery, and 95%-100% by three months after surgery. LASIK, in contrast, corrects vision much faster and with less pain postoperatively.
