Introduction. Modern computerisation, frequent use of contact correction, surgical interventions on the visual organ and long-term drug installations often lead to the formation and further progression of dry eye syndrome (DES) with subsequent increased sensitivity and inflammatory symptoms on the conjunctiva and cornea. Purpose. Evaluation of the condition of the eye surface in patients with a burdened general somatic history. Development of measures for prevention, diagnosis and comprehensive treatment of this condition. Material and methods. A retrospective analysis of disease histories and medical records of 108 patients (108 eyes) with phacoemulsification of uncomplicated cataract with IOL implantation was carried out. Patients were divided into three main groups based on the presence of burdening factors of somatic status and the course of the postoperative period: I group included patients with unburdened somatic status and no complications during the course of the postoperative period; II group included patients with burdened general somatic history with complications during the course of the postoperative period; 3rd group included patients with burdened general somatic history with complications during the course of the postoperative period. 3rd group of patients used a special scheme to prevent and treat inflammatory reactions from the eye surface. Results. 1st group patients were less likely to complain and had no clinical manifestations of conjunctival and corneal inflammatory responses. Accordingly, this group of patients did not require additional treatment, which is indicative of the low incidence of complications in this category of patients. II group patients who had been identified as predisposing factors for conjunctival and corneal inflammatory reactions and did not receive additional treatment were more likely to experience complaints and the frequency of clinical manifestations was 20% higher than III group patients. Patients in III group required additional treatment in the postoperative period. Conclusion. Prolonged prescription of high doses of drugs of different groups with different preservative and auxiliary substances content in patients after surgical intervention in some cases leads to damage to the conjunctival and corneal epithelium, which in turn causes an aggravation of symptoms of SSG with the development of inflammatory reaction of the conjunctiva and cornea. The application of preventive measures before and after the surgery leads to a significant reduction in the objective manifestations of the eye surface complications and, as a result, a reduction in the number of complaints from patients about discomfort in the postoperative period. Key words: ocular surface, dry eye syndrome, cataract, allergies, tear film stability.

Objectives: To evaluate the effectiveness of the optimized technique of transcleral diode laser cyclophotocoagulation (DCPC) in patients with unstable glaucoma.Methods. The retrospective analysis of outpatient records of patients diagnosed with open-angle compensated glaucoma, who underwent transcleral diodlaser DCPC in continuous-wave mode, has been performed. Totally, 44 outpatient records (44 eyes) have been analyzed.Results. The course of the postoperative period, patients’ complaints, and the ophthalmological status have been evaluated. The level of intraocular pressure (IOP) was determined on the day after the procedure, a week, 1, 3, 6 and 12 months after the operation. 12 months after the operation, the level of IOP decreased by 42.9 %. The number of antihypertensive drugs used by the end of the follow-up period decreased by 66.6 %: from 2.75 ± 0.4 to 1.0 ± 0.7 drugs (p = 0.001). The frequency of side effects was low and comprised 11.3 %. In 40 % of patients, manifestations of toxic-allergic reactions of the ocular surface to antihypertensive drugs decreased due to the possibility to reduce the frequency of instillations. The MCVA indicators remained stable throughout the entire follow-up period.Conclusion. Thus, the results of the conducted clinical study indicate that transcleral DCPC is an effective and safe technique with a high predicted result, since it compensates for the level of IOP, which allows to stabilize the progression of the glaucoma process. The method of trascleral DCPC provides a reduction and (or) correction of the hypotensive regime by reducing the number of antihypertensive drugs used. In patients with a toxic-allergic reaction from the ocular surface developed due to a prolonged use of antihypertensive drugs, it allows to reduce the symptoms and clinical manifestations by canceling and (or) reducing the number of antihypertensive drugs used, indirectly significantly improving the quality of life.

Purpose: to analysis the results of microimpulse transscleral diode laser cyclophotocoagulation (DCPC) technique as a method of choice in patients with open-angle subcompensated glaucoma (OAG) with toxic allergic syndrome of the ocular surface (TASOS).Methods. The retrospective analysis of patients’ case reports with subcompensated open-angle glaucoma and TASOS was performed. Transscleral diode laser cyclophotocoagulation (DCPC) in a microimpulse mode was used in their treatment. A total of 19 patients’ case reports were analyzed.Results. In the postoperative period, its course, patient’s complaints, ophthalmological status, visual acuity indicators were determined. The level of intraocular pressure was measured. Almost all patients (84.2 %) reached the target level of IOP. The frequency of side effects was low. In 36.84 % of patients, symptoms of TASOS decreased in response to hypotensive treatment due to reduction of instillation frequency.Conclusion. The use of micro-pulse cyclophotocoagulation in patients with subcompensation form of OAG and toxic-allergic ocular surface syndrome (TASOS) reduces the intensity of the drop regime of antihypertensive drugs. As a result, the manifestations of TASOS are reduced, which increases the patients’ quality of life in the postoperative period. In addition, the use of DCPC in microimpulse mode leads to stabilization of functional and structural indicators, helps to prevent a decrease in visual functions. Thus, the described method is characterized by safety, high efficiency and a wide range of indications for its performance. It allows to compensate the IOP with a minimum percentage of complications and stable postoperative results.
