Integrating best practices for Safer, Sharper Outcomes
CLEI deploys state of the art software that:
- Maps micro-irregularities in the cornea, flagging early keratoconus and preventing post-LASIK ectasia.
- Refines femtosecond-laser parameters based on millions of data points, enhancing flap precision.
- Calculates IOL power for cataract and refractive lens-exchange patients with sub-0.25 D accuracy.
The result: fewer surprises, faster visual recovery, and a higher percentage of 20/20 (or better) outcomes.
