Better Results, Quick Visual Recovery

Speed

The Eye-Q works with a pulse frequency of 400 Hz. This results in a correction time of only 2 seconds per diopter (considering a fully corrected optical zone of 6.5 mm). Thus, the average myopia correction takes about as little time as pouring a cup of coffee.

The rapid repetition rate also results in expedited vision regeneration, more comfort for the patient and a minimization of external influences.

Another advantage of both faster treatments and fewer post-treatment requirements is an optimized patient flow.

Thermically optimized shot distribution

Due to the high pulse frequency, there is a general theoretical risk of thermal effects. In WaveLight laser systems, this is prevented by the fact that only every fifth pulse overlaps a previous one, so that the affected spot has sufficient time to cool in-between pulse application.

This minimization of thermal effects is another decisive factor in speeding up the healing process.

Closed loop energy control

The integrated closed loop energy control guarantees a stable energy flow throughout the treatment. This ensures higher precision and safety, as well as a lower rate of enhancements.

As a part of the advanced PerfectPulse Technology, the closed loop energy control system manages the energy levels of every laser pulse during the treatment. At several points throughout the laser beam path the pulse energy is determined and output energy is automatically regulated in order to ensure stability.

Also, an ablation depth micrometer is used once every surgery day, guaranteeing energy calibration within a tolerance of less than ±1.5 µm by performing ablation on a PMMA target.
