Uses an older large broad beam (6mm) laser for most of treatment. This results in a shock wave of 100 atmospheres to the eye.
|
Designed as a flying spot.
|
Added on "small beam ability".
|
Can track the eye 4,000 X per second using a proven NASA designed laser tracker which can outpace fast saccadic eye movement.
|
Tracks the eye only 400 X per second. Using older style infrared cameras. Cannot outpace fast saccadic eye movement. |
| Can treat larger pupil size more effectively to reduce glare & haloes. |
Actual treatment zone still limited despite new "taper zone." |
| Can treat astigmatism better to reduce post op glare & haloes. |
Limited in treatment size of astigmatism which leads to more glare & haloes. |
| Smoother treatment for better healing. |
