Ophthalmic Probes
All probe shafts and tips are stainless steel. Refer to Table II for a listing of the MIRA
Ophthalmic Cryo Probes. The gas expansion chamber is at the very tip of the probes,
thereby assuring that freezing and defrosting occurs only at the target area. Warm high-
pressure gas insulates the shaft during freezing and defrosting cycles eliminating the need
for and insulating boot while reducing the danger of freezing adjacent tissues. The
handles present an unobstructed view of the probe shaft and remain comfortable to the
hand during use.
