Freezing Capacity of a Cryoprobe

Archives of Ophthalmology, 1968
Cryoprobe 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.

The Joule Thomson Cryoprobe

Archives of Ophthalmology, 1967
A cryoprobe working on the Joule Thomson principle using the expansion of carbon-dioxide gas is described. It is the first cryoprobe that can be applied to the lens at ambient temperature (room temperature) having almost instantaneous freezing and rewarming characteristics. Iris adhesion and laceration are virtually impossible.

Cryoprobe Isotherms: A Caveat and Review

Journal of Endourology, 2010
Cryotherapy 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.

A Transilluminating Retinal Cryoprobe

Archives of Ophthalmology, 1968
ONE OF the problems in the treatment of retinal tears by the application of cyrocongelation is the precise localization of the freezing relative to the hole. Often the freezing does not appear in the center of the mound produced by indentation of the cryoprobe.

A New 20-Gauge Intravitreal Cryoprobe

American Journal of Ophthalmology, 1980
A new intraocular 20-gauge (0.89-mm) cryoprobe is compatible with the Ocutome-Fragmatome system. The iceball forms only at the tip and there is a rapid freeze and defrost cycle. Actual clinical testing during vitreous surgery showed the probe to be reliable and easy to use.

A 20-Gauge Intravitreal Cryoprobe

American Journal of Ophthalmology, 1980
A 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.

Retinal Cryoprobe in Orbital Tumor Management

American Journal of Ophthalmology, 1975
We used the retinal cryoprobe in the surgical management (biopsy and excision) of orbital and ocular adnexal tumors in four patients. The strong bond between the cryoprobe tip and the tumor allowed application of moderate traction to the tumors, facilitating their removal.

A Self-Illuminating Intravitreous Cryoprobe

Archives of Ophthalmology, 1968
Severe 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.

The Application of Cryoprobe Therapy in Orthopedic Oncology

Orthopedics, 2014
The cryoprobe is a relatively new surgical tool offering a more selective destruction of unwanted cells. Using expanded versions of basic thermodynamic formulas of conduction and convection, mathematical models are becoming more effective at mapping out the zone of destruction that can be expected when using cryoprobes.
