The intended use of the Pocket III is the same as the intended use of the predicate device and the indications for use are also nearly identical. Both devices are prescription devices for use by trained healthcare providers. The Pocket III has the same technological characteristics as the predicate device as described in the table above. Both devices are ophthalmic ultrasonic pachymeters for measurement of corneal thickness. The specifications for both devices are similar and both devices comply with IEC 60601-2-37. Both are powered by a power supply or a battery. Both devices meet electrical safety and EMC standards and both are made from the same biocompatible patient contacting materials. Both devices use the same three formulae for correction of a measurement in accordance with IOP. Therefore, the Pocket III is substantially equivalent to the predicate device.

## Performance Data

Non-clinical testing was performed to verify that the proposed device met all design specifications and is substantially equivalent to the predicate device.

value of test block. After measurements, all results are acceptable and compliant with an accuracy of ±5μm.

Additionally, software verification and validation activities were performed to ensure the device performed as intended and software documentation appropriate for the Moderate level of concern was provided.

In conclusion, non-clinical testing supports substantial equivalence to the predicate device.
