Summary:

Purpose: to assess the dynamics of intraocular pressure (IOP) after cataract phacoemulsification (CFE) with intraocular lens (IOL) implantation in patients with cataract in combination with primary open-angle glaucoma (POAG). Material and Methods. The subject of this study was the analysis of IOP after CFE in 65 patients (89 eyes) with cataract in combination with POAG. Among the examined patients, the initial stage of glaucoma was noted in 14.6% cases; developed stage in 55.1 % cases, far-reaching stage in 30.3% cases. IOP was compensated in 84.5% cases, and sub-compensated in hypotensive mode in 15.5% cases. The observation period was from 1 month up to 2 years. Results. In dependence of IOP after surgery, patients were divided into three groups: IOP exactly like in preoperative level, below and above the initial IOP In most cases, at all times IOP corresponded to the preoperative level and after 2 years it was noted in 77.4%. The number of patients with ophthalmotonus below the baseline (1-8 mm) decreased from 63.2% in 1-3 months after surgery to 16.1 % in two years. An increase in ophthalmotonus (by 3-4 mm) was noted in 27% of cases, however, a persistent increase in IOP, which required correction, was 7.9% at stage III of glaucoma, and in the rest of the eyes IOP normalized by itself. Conclusion. According to the results of the study, it can be concluded that there is an ambiguous effect of CFE with IOL implantation on IOP in patients with cataract in combination with POAG, which necessitates further study.

Summary:

Purpose: to evaluate the effectiveness of using Pentacam HR sheimpflug camera for objective determination of cataract density. Material and Methods. The subject of the study was the method of determining the density of the lens (densitometry) by the Pentacam HR sheimpflug-camera. The object of the study were patients with age-related cataracts (147 eyes). All patients underwent ultrasound phacoemulsification with implantation of various types of intraocular lenses (IOL). Before treatment, the density of the lens was determined by non-contact method using PNS (Pentacam Nucleus Staging). During the surgery, the density of the lens was determined by the surgeon on a set of factors: the color of the nucleus, the mechanical density, the emulsification easiness. The equivalent ultrasound time and the fact of compliance or discrepancy in the degree of density of the lens with two methods of its determination were recorded for each patient. Results. It was found that the density of the lens recorded by the Pentacam HR is in a direct strong correlation with the equivalent ultrasound time. It was shown that the discrepancy between the PNS method and the contact method performed by the surgeon significantly lengthens the surgery time. Conclusion. The Pentacam HR sheimpflug-camera is an accurate method of determining the density of the cataract before the surgery. The advantage of this method is that it is non-contact, quick and relatively easy-to-perform with the possibility of objective assessment.

Clinical performance of system for ultrasonic cortex aspiration during phacoemulsification

Year: 2018, volume 14 Issue: №4 Pages: 811-815

Organization: Bashkir State Medical University of the Russian Health Care, ZAO Optimedservis
Summary:

Purpose: to study the performance and safety of the use of system for cortex aspiration with the possibility of additional dosed low power ultrasound during phacoemulsification. Material and Methods. The comparative evaluation of developed system for cortex aspiration with the possibility of additional dosed low power ultrasound (main group, n=36, ophthalmological surgical platform Optimed Profi) and the traditional system for cortex aspiration (control group, n=40, ophthalmological surgical platform Centurion Vision System) were performed. Results. Using the system for cortex aspiration decreases mean time of cortex aspiration. In the main group the mean time of cortex aspiration was 72.6±24.3 s, in the control group 93.9±48.0 s (p<0.05). Intraoperative complications were not observed in the main group. Posterior capsule rupture was detected during the cortex aspiration in 1 patient (2.5%) in the control group. Conclusion. The system for cortex aspiration with the possibility of additional dosed low power ultrasound allows decrease the time of cortex aspiration, to create conditions for a safer removal of cortex, compared with traditional technology.

Summary:

The purpose is to study the dynamics of general and primary incidence of eye diseases and accessory apparatus among the population of the Central Black Earth region for the period 2008-2017, in comparison with similar indicators in the Russian Federation. Material and Methods. The article presents the data on the dynamics of general and primary incidence of eye diseases as a whole, as well as myopia and cataracts in comparison with Russia and the five regions of the Central Black Earth region (Belgorod, Voronezh, Kursk, Lipetsk, Tambov) from 2008 till 2017 Results. A comparative analysis of morbidity indicators allowed us to identify regions that are unfavorable for ocular morbidity in general and for cataracts and myopia in particular. Conclusion. The total incidence of eye diseases among the population of Russia in 2008 accounted 10994,0±2,6 cases, over ten years there was a decrease to 10370,9±2,5 cases per 100000 persons. The primary incidence rate of eye diseases among the population of Russia in 2008 accounted 3422±1,5 cases, over a ten-year period there was a decrease to 3161,1±1,4 cases per 100000 persons. Among the regions of the Central Black Earth region in the Belgorod region, the indicators studied are higher than the average in Russia. The incidence of eye diseases, in particular, cataracts and myopia tends to decrease. However, its level remains significantly high, which requires the improvement of organization of eye care and the development of measures aimed at preventing the development of eye pathology.
