ABSTRACT
PURPOSE: To analyze visual functions in moderate and high myopic patients with retinal detachment that developed after implantation of a trifocal intraocular lens (IOL). MATERIAL AND METHODS: The study analyzed the functional outcomes achieved in 3 patients (4 eyes) with retinal detachment developed after implantation of AcrySof IQ PanOptix («Alcon¼, USA) and AT LISA tri 839 MP («Carl Zeiss Meditec¼, Germany) during the follow-up period of 24 months. Patient examination included measurements of visual acuity at far (4 and 5 m), near (40 cm) and intermediate distances (60 cm, 80 cm), spatial contrast sensitivity, spherical equivalent of refraction, and a survey of patients for subjective satisfaction of the obtained vision. RESULTS: In four eyes of three patients with moderate and high myopia, rhegmatogenous retinal detachment was diagnosed during the follow-up period at 4 to 12 months after phacoemulsification of cataract with trifocal IOL implantation. The best visual indicators were found in patient N. as a result of surgical treatment of bilateral rhegmatogenous retinal detachment due to high myopia: visual acuity (VA) at far distance was 1.0 for each eye (with 100 points on the VF-14 questionnaire). In patients P. and M., after the development of unilateral rhegmatogenous retinal detachment, complete retinal reattachment was achieved after surgery with VA at far distance 0.55 (OS) in patient P. and 0.4 (OD) in patient M. (95 and 86 points on VF-14, respectively). CONCLUSION: Good visual functions were achieved in three patients with trifocal IOL after surgical treatment of the rhegmatogenous retinal detachment that developed due to myopia. The implanted trifocal IOL did not affect the effectiveness of vitrectomy. After the treatment patients retained the ability to see at different distances.

PURPOSE: To compare visual outcomes after implantation of two models of diffractive trifocal IOLs using various vision assessment systems. MATERIAL AND METHODS: The study included 25 patients (25 eyes) who were implanted with AcrySof IQ PanOptix (TFN) and 25 patients (25 eyes) implanted with AT LISA tri 839 MP (TRI). Postoperative examination at 1 year included assessment of monocular visual acuity for far, intermediate and near distance using decimal scale, as well as LogMAR and an interactive computer program (ICP). Contrast sensitivity was assessed with the Optec 6500 device. A questionnaire was used to evaluate subjective quality of vision and the intensity of optical phenomena. RESULTS: Uncorrected visual acuity (UCVA) at distance, intermediate and near was better in the TFN group in comparison with the TRI group as measured with decimal scale, ICP and LogMAR. Under photopic and mesopic conditions with and without glare, at all spatial frequencies the contrast sensitivity function (CSF) was higher after implantation of TFN in comparison with TRI. The average VF-14 score was 97.2 after implantation of TFN and 96.7 after implantation of TRI. The amount of patients who required spectacle correction after the surgery was 5.5% less in the TFN group compared to the TRI group. CONCLUSION: High visual outcomes at all distances were observed in patients after implantation of both trifocal IOLs with TFN showing a slight advantage. Evaluation of the visual outcomes using various systems showed the benefits of the ICP assessment. The CSF had typical configuration with maximum value in the mid-range region and a decrease in the high-frequency range after implantation of both IOLs, however the indicators were better in the TFN group. The postoperative period was characterized by high levels of patient satisfaction and spectacle independence in both groups.

We carried out complex examination of 68 adolescents aged 11-17 years with primary obesity which in addition to assessment of clinical-anamnestic, laboratory data and functional parameters of cardiovascular system included registration of reaction of brachial artery endothelium to reactive hyperemia. Vascular endothelial dysfunction (VED) was found in 66% of obese teenagers. Obesity in adolescents with VED was characterized by aggravated course with higher fat mass index (36.8 +/- 4.39%) and prevalence of hypothalamic (42%) and metabolic (8.8%) syndromes. Stable arterial hypertension (AH) found in 37% of examined adolescents was 1.5 times more often registered in those with VED. We distinguished 4 groups of adolescents with various degree of risk of development of cardiovascular disorders: with stable AH and VED (group I), with stable AH and normal function of vascular endothelium (group II), with normal or labile arterial pressure with VED (group III), with normal or labile arterial pressure with normal function of vascular endothelium. It is expedient to supplement examination of obese adolescents with assessment of the state of vascular endothelium aiming at determination of degree of risk of development of atherosclerosis and/or stable AH.
