Important features and benefits of the new Star S4 platform include:

Iris Recognition (IR) - The first FDA-approved fully automated, non-contact method of aligning the correct treatment to the corneal site. This greatly reduces the impact of rotational movement of the eye during treatment.

Active Track 3-D Active Eye Tracking with Automatic Centering - The first FDA-approved tracker in the industry to track X, Y, and Z eye movements. This has improved and enhanced safety and precision.

Delivers the broadest range of FDA approvals including the first FDA approval to treat wavefront-guided custom hyperopia with astigmatism and wavefront-guided custom mixed astigmatism. Over 92% of patients in the US are now potentially eligible for treatment.

Variable Spot Scanning (VSS) produces variable beam sizes from as small as 0.65 mm up to 6.5mm. This allows the new VISX to deliver corrections with greater flexibility and precision than ever before.
