Archives of Ophthalmology, 1973
To the Editor. —Wirtschafter and Sohmer have documented the electrical hazards of cryoextraction in theArchives(87:117, 1972). A potential mechanical hazard also exists with the same instrument. On July 25, 1972, cataract extraction with the patient under local anesthesia was attempted using the Amoils curved cataract probe.

Freezing Capacity of a Cryoprobe
Archives of Ophthalmology, 1968Cryoprobe capacity can be compared using the weight of ice formed by freezing the surface of distilled water at 37 C. The effect of increasing the area of contact while still maintaining a constant tip temperature is illustrated. The thermal characteristics of the contact plate alter the amount of water or tissue frozen.

Cryoprobe Isotherms: A Caveat and Review
Journal of Endourology, 2010Cryotherapy is a form of thermal therapy for the treatment of small renal masses, particularly in high-risk patients. However, optimal application and the critical temperature for in vivo cell death have not been well established. Additionally, most centers do not currently monitor temperature during the procedure.

Experimental cryoprobe production of intrahepatic portocaval shunt
Journal of Surgical Research, 1977Abstract Experiments have been performed on 25 pigs creating a shunt through the liver substance between the portal vein and the vena cava. The technique involves passage of a small caliber (5 mm) probe via an incision in the portal vein to a major branch of the left hepatic vein.

A Self-Illuminating Intravitreous Cryoprobe
Archives of Ophthalmology, 1968Severe complications associated with the extraction of the dislocated lens have made many surgeons hesitant to operate in such cases. However, with cryoextraction of the lens, using a controllable probe inserted into the eye at ambient (room) temperature, the operative risk is greatly reduced.

Archives of Ophthalmology, 1981
In Reply. —I would like to thank Dr Eiferman for his comments regarding our recent work in cryosurgery as well as his suggestions regarding modification of the tip of the cryoprobe. As I stated in our article, we also treat individual eyelashes with an epilation tip, which is the small pointed tip that is commercially available and attaches to the ...

A 20-Gauge Intravitreal Cryoprobe
American Journal of Ophthalmology, 1980A 20-gauge intravitreal cryoprobe designed for endocryopexy during trans pars plana vitrectomy is now available. The probe may also be used for intracapsular cataract extraction and open-sky intravitreal cryopexy.

“Finger-tip” cryoprobe assisted enucleation
American Journal of Ophthalmology, 2005To report the use of a new cryotherapy probe to induce proptosis during enucleation surgery.Interventional case report.Two patients with uveal melanoma and secondary glaucoma were treated by enucleation. A large surface area (70 mm(2)), spatulated, end-freezing cryotherapy probe ("Finger-tip" probes, MIRA, Inc.) was used to induce proptosis during ...

Investigation of Temperature Fields Around Embedded Cryoprobes
Journal of Biomechanical Engineering, 1986The temperature fields around cryoprobes were investigated analytically and experimentally. Two cryoprobes were employed: a spherically shaped general purpose probe utilizing liquid nitrogen and a cylindrical “glaucoma” probe utilizing the Joule-Thomson effect in gaseous CO2. Both probes were operated by commercial cryostats.

An efficient cryoprobe to inactivate cortical surfaces
Brain Research Bulletin, 1986This paper describes a cryoprobe constructed of glass capillary tubes commonly employed for cellular recordings. It is inexpensive, it is easily and rapidly constructed and most importantly it can easily be adjusted to cool larger areas and tightly fit brain curvatures and gyri.
