LASEK/PRK Eye Surgery

LASEK/PRK:

LASEK is a relatively new laser vision procedure that combines certain elements of both the PRK (Photo Refractive Keratectomy) and LASIK procedures and may offer some advantages for patients. Instead of removing the epithelium as with PRK, a flap of surface epithelium is loosened with a diluted alcohol solution and moved aside. The surface under the epithelium is treated with the laser and the epithelial flap is returned to its original position, as with LASIK. A protective, soft contact lens is then placed over the cornea to make the eye more comfortable while it heals.

Using the epithelium flap as a natural protective bandage with LASEK, as opposed to completely removing the epithelium as with PRK, may improve healing, reduce postoperative discomfort and the incidence of postoperative haze. The margin of safety with LASEK is increased as the need for a microkeratome is eliminated.

WaveLight® Ex500 Excimer Laser:

The WaveLight® Ex500 Excimer Laser is the most recent and state-of-the-art laser on the US market today, and can be used for both conventional and customized LASIK, PRK, and LASEK. The Excimer laser comes with a tracking device that follows extremely small eye movements enabling the surgeon at Global Laser Vision to fine tune ablations done for PRK and LASIK to achieve improved outcomes.

Excimer in San Diego – Built for Speed and Superb Outcomes

The WaveLight® Ex500 Excimer Laser is the fastest Lasik procedure platform available in the US:

          • The WaveLight® EX500 Excimer Laser is the only excimer laser to operate at 500 Hz, with an average treatment time of approximately 1.4 seconds per diopter1
          • The swivel bed that comes along with the Ex500 Excimer Laser and Femtosecond Laser is proposed to enhance time it takes to create the flap and the corrective laser treatment

This New Advanced Refractive Technology Offers Several Benefits Including:

          • Decreased chance of cornea dehydration
          • Thinner lap creation
          • Increased eye tracker speed
          • Fast flap creation

Customized Optimized LASIK

The WaveLight® EX500 Excimer Laser is extremely flexibly and lets the surgeons expand their refractive treatment abilities:

  • Wavefront Optimized® treatment

Focused on Precise Accuracy

Powerful 1050 Hz-type multi-dimensional eye tracker, synchronized at 500 Hz, the WaveLight® EX500 Excimer Laser offers safety and exceptional precision:

        • Movement tracking with just approximately 2 milliseconds of latency
        • Dynamic pupil tracking from 1.5 mm to 8.0 mm

Optimized Shot Distribution

Utilizing proprietary PerfectPulse Technology®, the WaveLight® EX500 Excimer Laser maintains a high pulse frequency with a minimized thermal load4,1:

    • Only 1 pulse in 5 is allowed to overlap
    • Optimizes temporal and spatial shot distribution
    • Additional pulses are sent to the periphery to compensate for energy loss
    • Reduces the potential for nighttime glare
