Product

Schoitz weights are manual devices used with Schoitz tonometers and are intended to measure intraocular pressure by applying a known force on the globe of the eye and measuring the amount of indentation produced (Schiotz type) or to measure intraocular tension by applanation (applying a small flat disk to the cornea) and are sold under the Ambler Surgical brand name.

Reason

The reason these devices are being withdrawn from the market by Instrumed is that Instrumed did not market these devices prior to September 26, 1976, and therefore, does not meet all FDA requirements to market the devices as "Pre-Amendment" devices.
