Contoura™ Custom Lasik and Blade-free LASIK for Enhanced Vision Service
Although conventional LASIK eye surgery has helped millions of people achieve clearer, sharper vision, many potential patients have avoided surgery due to fears about the mechanical blade that was used in the first step of LASIK. Dr. Helen Wu now offers blade free custom LASIK at our refractive surgery center. Through the use of ultra-precise lasers and advanced computer software, our patients can now undergo safe, effective vision correction surgery without the risks associated with a mechanical blade. Our patients are experiencing high satisfaction with their visual outcomes. While some patients still report experiencing night vision changes or dry eyes post-operatively, the symptoms are less significant than they were prior to surgery, and tend to decrease over time.
Mapping the Eye
Prior to surgery, the Wavelight Topolyzer VARIO is used to map the cornea and enables visualization of vision defects that are unique to each patient’s eye. These defects, or aberrations, can cause vision problems such as halos or glare even when a patient’s visual acuity is 20/20. The refractive surgery team enters data from the testing equipment into the computer that guides the excimer laser. Topography-guided imaging can help the surgeon correct for aberrations and achieve a better result.
Femtosecond Blade Free Technology
The outstanding results and safety of blade-free LASIK is due to the Wavelight®FS200 technology. The system consists of two components: the software and the extraordinarily precise femtosecond laser. The first step of LASIK surgery is the creation of the corneal flap. A femtosecond laser uses energy pulses to create tiny bubbles of air and water to separate the corneal tissue without the use of a blade. The high-speed laser accomplishes flap creation in about 20 seconds.
The Blade-Free Advantage
Blade-free technology is more comfortable and safe for the patient. Some of its specific advantages are:
- The ability to program corneal thickness enables more patients to have LASIK.
- Decrease in dry eye symptoms
- Decrease in corneal abrasions and epithelial ingrowth
- Better positioning of the corneal flap leads to faster recovery
Excimer Laser Technology
In the second step of LASIK, the surgeon lifts back the corneal flap to access the deeper corneal tissue. Dr. Wu uses the Wavelight ® EX500 excimer laser to reshape the corneal contour. The Contoura system incorporates the information from testing and mapping to guide the laser with great precision. This eliminates refractive (focus) errors and ocular surface irregularities.
Advantages of new Excimer Laser Technology
Technology has advanced and improved the safety, efficacy and predictability of corneal surgery. The excimer laser is now so advanced that it can treat nearsightedness, farsightedness, astigmatism, and a combination of the three. Dr. Wu chooses to use the most advanced excimer laser with a wide range of FDA approvals in order to offer her patients a truly customizable procedure. The time has never been better to have a LASIK or PRK procedure!
