- LASIK Flap Creation
- Corneal Reshaping
Refractive Surgery Patient Screening
LASIK surgery at the UCLA Laser Refractive Center has enjoyed enormous success for more than a decade now due not only to the cutting edge laser technology used during surgery, but also because of the comprehensive screening process utilizing the very latest diagnostic technology to determine your candidacy for LASIK.
Orbscan® IIz (Bausch & Lomb)
The UCLA Refractive Laser Center uses the Orbscan IIz topographer during the refractive surgery screening process. This advanced topographer analyzes the physical shape and contours of your cornea and allows the surgeon to decide if it has a suitable shape: is the cornea healthy and thick enough for treatment? The Orbscan was the first topographer designed to measure the shape of both the front and back surface of the entire cornea, essential measurements for determining corneal health. The system uses this data to generate a map detailing thickness changes across the cornea. The Orbscan IIz is able to provide such high precision information by capturing 9000 data points from the cornea within seconds during each measurement. Dr. Hamilton and his colleagues published an important article in the American Journal of Ophthalmology describing how to use the Orbscan device to distinguish normal from abnormal corneal shapes*. The presence of certain abnormal corneal shapes may suggest LASIK surgery should be deferred, possibly in lieu of an alternative procedure.

Ocular Response Analyzer (Reichert)
Corneal biomechanical properties influence the results and outcomes of ocular measurements and procedures, and may hold clues to diagnosing and managing ocular diseases, including keratoconus and glaucoma. Until recently, assessing the biomechanical properties of corneal tissue has not been possible, confining practitioners and researchers to measuring purely geometrical aspects of the cornea, such as thickness and topography. The Ocular Response Analyzer (ORA) provides a way to measure the strength of the cornea. The system uses an infrared light source and high speed camera to measure the deflection of the cornea in response to a precisely controlled air puff. At the UCLA Laser Refractive Center, Dr. Hamilton was the first eye surgeon in Los Angeles to integrate the ORA into the LASIK screening process. Dr. Hamilton and his colleagues have published several scientific studies on corneal biomechanics, including an article suggesting the use of a femtosecond laser to create the LASIK flap has a more consistent and predictable effect on biomechanics than the use of a microkeratome (blade) system*.

LASIK Surgical Planning
Once all your measurements are completed, Dr. Hamilton and his colleagues use a sophisticated software program that analyzes your unique characteristics (e.g. age, gender, amount of correction, environmental conditions, etc.) to determine the optimum laser setting for each of your eyes. At the UCLA Laser Refractive Center, we pride ourselves in tracking patient results and using those results to improve patient outcomes. Dr. Hamilton and his colleagues presented a paper at the American Society of Cataract and Refractive Surgery meeting describing an advanced nomogram he developed to optimize patient outcomes*. A nomogram is an equation derived using previous patient information to provide the best laser settings for optimized future patient outcomes. Take a look our Patient Outcome Charts to see for yourself the outstanding results nomograms have provided patients at the UCLA Laser Refractive Center.

LASIK Flap Creation
Dr. Hamilton uses the highest quality Laser Visumax-Zeiss!
“The VisuMax® Femtosecond Laser Its remarkable features are its precision and innovative detail. With the VisuMax®, Zeiss is significantly shaping the world of refractive surgery. This groundbreaking laser system employs high-performance femtosecond laser technology and is characterized by its outstanding cutting precision, highly efficient speed and gentle treatment technique”.
Here at UCLA we use the latest technology and provide high-quality care. Call now about scheduling your appointment for a complimentary LASIK screening consultation 310-825-2737!
The accuracy and predictability of the VisuMax® laser have allowed some patients who were previously ineligible for LASIK to now have the procedure. With the FS laser, unlike with mechanical instruments, your surgeon is able to precisely program the dimensions of your flap (diameter and thickness) based on what’s best for your eye. Dr. Hamilton and his colleagues published a scientific study suggesting the use of a femtosecond laser to create the LASIK flap has a more consistent and predictable effect on corneal biomechanics (i.e. strength) than the use of a microkeratome (blade) system.2 Your UCLA eye surgeon will discuss with you whether Blade-FREE LASIK or an alternative refractive procedure best matches your eye condition and visual needs. 2.

ALLEGRETTO WAVE® Eye-Q Excimer Laser System
The final step in the LASIK experience is the reshaping of the cornea. An excimer laser is used to precisely remove microscopic amounts of corneal tissue to change the curvature of the cornea. The ideal excimer laser is fast, precisely controlled with advanced eye tracking and comfortable for the patient. At the UCLA Laser Refractive Center, our staff takes pride in offering you the very latest excimer laser technology: The Allegretto Wave Eye-Q (Alcon Laboratories).
The Eye-Q excimer laser is the fastest laser available in the industry. At 400 Hz, it is 8 times faster than its predecessor. Faster treatment times translate to more consistent and predictable patient outcomes as well as an easier, more comfortable patient experience. With speed comes the responsibility to track the eye precisely to ensure every pulse is placed in the exact, intended location. The Eye-Q eye tracking system is the most robust currently available, reliably locking on to the pupil regardless of eye color or lighting conditions. At the UCLA Laser Refractive Center, the Eye-Q system also features an ergonomically designed patient bed which automatically swivels between the VisuMax® and Allegretto lasers, obviating the need to move the patient between steps of the LASIK procedure.
