Emerald™ is approved for the following range of treatment:

Approved Treatment Range:

Refractive Error	-1.00 to -5.00 Diopters
Cylinder	< 1.50 Diopters
Keratometry	40.00 to 46.00 Diopters

Standard Lens Parameters:

Diameter*	10.2 mm, 10.6 mm, 11.0mm
Power	+ 0.75 Diopters
Center Thickness	0.22 mm

* selection based on HVID

Maximum targeted correction is -5.00 D. Call to discuss your options for patients with refractive error greater than -5.00 D or 1.50 D of cylinder.

Only Rx, Keratometry and HVID are needed to achieve success; no calculators or trial lenses are required.

Subsequent visits may benefit from use of corneal topography, but for minimizing chair time on the initial fit and for maximizing success, no other system compares to Emerald.
