Built-in voice communication for easier work. System informing about key figures during procedure.
Pressure and gas flow are set automatically, any manual adjustment is not necessary. Automatic working modes (stop, preparation, ready, freezing, cleaning).
The working medium for CRYO-S ® Electric II is carbon dioxide: CO2 (-78°C) or nitrous oxide: N2O (-89°C), very efficient and easy to use gases.
A 10 liter cylinder of CO2/N2O serves for approximately 60 procedures.
User friendly interface
CRYO-S ® Electric II is controlled by a microprocessor and all the parameters are displayed and monitored on a LCD screen. Cryoprobe temperature, cylinder pressure, gas flow inside of cryobrobe and procedure time are displayed during freezing.

Cryoprobes which meet the highest standarts of quality
Wide range of contact cryoprobes – single and multiple use as well. Needle shaped cryoprobe is only 0,8 mm in diameter – excellent for treatment of intramucosal conchoplasty. Special construction enables precise freezing and fast defrosting.
High quality of cryoprobes which are cover with 24 carat gold.
Sterilization cryoprobe possible in autoclaves 134°C, 3 minutes
The wide range of cryoprobes for vitreous, retinaland and palpebrals.

Functional modes of unique cryoprobe prepairing system:
- Standard – Cryoprobe is cleaned before each procedure for several seconds and than few seconds of testing freezing is performed. In this mode cryoprobe is tested and prepared according to parameters programmed on attached microchip. When such preparation is finished cryoprobe is ready for freezing.
- Service – it starts automatically when decreased flow rate in cryoprobe or cryoprobe blockage is noticed. It can be performed also during the procedure. Service mode is diagnosing and solving problems caused by previous improper use of the cryoprobe, improperly performed sterilization or low quality of gas.
Cryotherapy have been used to freeze living tissue for the purpose of treating benign and malignant lesions. Within the last century, ophthalmologists have found cryotherapy to be useful in treating a variety of ocular pathologies. Cryosurgery has been used to treat a variety of ophthalmic conditions, including surface and intraocular pathology. Cryosurgery may be preferable in treating certain surface and intraoculus diseases (including benign and malignant lesions), as there are few post-operative adverse events and limited long-term complications when compared to radiation and chemotherapy.
Application in ophthalmology
- Retinal cryopexy continues to be used as a means of repairing retinal breaks (holes or tears), which have long been recognized to be the cause of most retinal detachments. Application of cold to the choroid and retinal pigment epithelium yields cell death and subsequent scarring, resulting in sealing of the edges of retinal breaks.
- Cyclocryopexy for advanced glaucoma – In severe intractable glaucoma that is not amenable to conventional glaucoma medication or surgery, ocular cryopexy applied to the ciliary body through a transscleral application can reduce aqueous production, thereby lowering intraocular pressure Peripheral retinal cryoablation for neovascular glaucoma – Destruction of the peripheral retina by means of cryotherapy can cause iris neovascularization to recede in neovascular glaucoma.
- Retinal cryoablation for retinopathy of prematurity (ROP) – In multicenter prospective clinical trials, destruction of the peripheral retina in premature infants with ROP slows disease progression and improves the chance of maintenance of vision; ocular cryotherapy has markedly altered the prognosis of ROP.
- Retinal cryoablation for peripheral uveitis (intermediate uveitis or pars planitis) – Destruction of the far peripheral retina can reduce peripheral uveitis and cause improvement in macular edema secondary to peripheral uveitis.
- Transconjunctival cryotherapy for retinal toxoplasmosis – Active toxoplasmic lesions in the peripheral retina can be treated with transconjunctival cryotherapy; Toxoplasma gondii organisms are destroyed by extreme cold.
- Retinal cryoablation for Coats disease – This most likely basis for this use a decrease in production of vascular endothelial growth factor (VEGF) by the peripheral retina and a subsequent decrease in vascular proliferatio
- Peripheral retinal cryoablation to induce regression of proliferative diabetic retinopathy – Although this approach has been used successfully, it has largely been supplanted by panretinal photocoagulation with an argon laser, which has greater efficacy.
- Transconjunctival cryopexy for larva migrans of the eye – The intraocular nematode in this condition (Toxocara canis or Toxocara cati) can be destroyed by transconjunctival cryopexy if it is located away from the posterior retina.
- Peripheral cryoablation of the retina and choroid for retinal vasculitis of various etiologies.
- Cryoablation of malignant peripheral melanomas of the choroid or ciliary body – This allows salvage of vision and the eye in selected cases.
- Cryoablation of retinoblastomas – Peripheral retinoblastomas can be successfully treated with transconjunctival or transscleral cryopexy.
- Cryoablation of metastatic lesions to the choroid. These secondary malignancies (most commonly from the breast or lung) can be destroyed with cryosurgery if their location is peripheral enough.
- Cryosurgery for conjunctival neoplasias of the epithelium – This can be considered as an alternative to surgical excision.
- Cryotherapy for malignancies of the lids (eg, basal cell carcinomas).
- Freezing of lash roots for recurrent trichiasis
