Baush & Lomb Technolas® 217z

Clinical Trial Results
Bausch & Lomb’s Technolas® 217z is a new generation excimer laser that uses innovative flying spot technology to increase the accuracy and efficiency of laser eye surgery.  In the FDA clinical study conducted for this laser, the key outcome measures exceeded the values recommended by the FDA.  The following data illustrates the superiority of this laser system platform in patients with myopia (nearsightedness) with < 7.0 diopters of sphere and < 3.0 diopters of astigmatism after just six months of surgery.

Uncorrected vision of 20/40 or better after surgery

  • Technolas 217z:  99.7%
  • FDA benchmark for approval:  85%


Uncorrected vision of 20/20 or better after surgery

  • Technolas 217z:  87.3%
  • The FDA does not presently have an established target value.


Deviation from attempted correction within 1.00 diopter after surgery

  • Technolas 217z:  99.2%
  • FDA benchmark for approval:  75%

 

Deviation from attempted correction within 0.50 diopter after surgery

  • Technolas 217z:  86.7%
  • FDA benchmark for approval:  50.0%


Loss of the ability to see fine visual detail after surgery

  • Technolas 217z:  no more than 0.3%
  • FDA benchmark for approval:  no more than 5%


Experienced an increase of refractive astigmatism after surgery

  • Technolas 217z:  0%
  • FDA benchmark for approval:  no more than 2.00 diopters


Technological Highlights

  • The only laser designed ergonomically for LASIK and features a proven LASIK algorithm.  LASIK is the fastest growing refractive procedure for vision correction.
  • Newest generation flying spot/true scanning laser increases accuracy and produces an extremely smooth corneal surface.
  • A scanner feedback mechanism ensures quality control during the procedure by monitoring the accuracy of each pulse.

 

Design Highlights

  • Evergreen platform design will incorporate future software and technology upgrades effortlessly.
  • Strategic space design allows maximum istrument control and flexibility for surgeons.
  • Ergonomic design provides excellent comfort for patients.
