Background. At an appointment with an ophthalmologist, patients with pathological conditions of the eyelids are often dissatisfi ed with the effectiveness of the traditional surgical treatment.The aim: assessment of the functional state of the eye adnexa after cryodestruction of the chalazion with an increased risk of complications using modern cryosurgical equipment.Material and methods. Clinical studies were carried out in 254 patients (277 eyes) with chalazion, including a complicated course of the disease, with cryodestruction of the chalazion using an autonomous cryoapplicator made of porous-permeable titanium nickelide.Results. Cryosystems of the new generation, in comparison with the well-known industrial cryoapparatus, diff er in new properties. They can signifi cantly improve the quality of cryotherapy in surgery due to a clearer localization of cryotherapy and a high rate of heat removal from the surface of altered tissues without damaging the surrounding tissues. Depending on the size of the pathological formation, the duration of the exposure, the frequency of repetitions of the applications during the session, the regression of the chalazion occurred within 1–1.5 months with the preservation of the integrity of the intermarginal space and the functional state of the eyelid.Conclusion. Analysis of the data obtained indicates a high clinical and cosmetic effi ciency of cryosurgery of the eyelid chalazion using an autonomous cryoapplicator made of porous-permeable titanium nickelide.

Objective: to evaluate the clinical efficiency of eyelid cryotherapy with an autonomous titanium nicke lide cryoapplicator in patients with ocular rosacea regarding the dynamics of pro- and anti-inflammatory cytokines contents at local levels. Materials and methods. 65 patients with ocular rosacea were observed. Depending on the therapy received, the patients were divided into two groups: in the main group, eyelid cryotherapy was applied for 2 weeks with an autonomous cryoapplicator made of porous-permeable titanium nickelide, and in the reference group, the patients received a traditional treatment for a month. The contents of cytokines (IL-1β, IL-8, IFN-α, IL-2, IL-10) in lachrymal fluid was evaluated by ELISA on Days 3, 7 and 30 after treatment. Results. The opposite nature of cytokine balance changes and the ratio of its pro- and anti-inflammatory link during the follow-up period were revealed. A reliable dynamic increase of examined IFN-α and IL2 content in the lacrimal fluid after cryostimulation can evidence for an adequate activation of cellular immunity link, as well as for enhancement of regeneration mechanisms. Conclusion. The analysis of obtained data evidences for a high efficiency of clinical and immunological effect of lid cryotherapy using titanium nickelide cryoprobe for ocular rosacea treatment.
