Clinical effect of defocusing frame lens on myopia control in adolescents / 中国现代医生

@#Objective To investigate the clinical effect of highly aspherical lenslets(HAL)in myopia control in adolescents.Methods Totally 101 cases(202 eyes)of adolescent myopia patients treated in ophthalmology outpatient department of our hospital from January 2021 to February 2022 were selected as the study objects.Of these,43 cases(86 eyes)wore HAL lenses as an observation group and 58 cases(116 eyes)wore single-vision spectacle lenses(SVL)as a control group.After 12 months of follow-up,the equivalent spherical lens degree and axial length were recorded in 6 months and 12 months respectively.Results The change of equivalent spherical lens in the HAL group was(-0.18±0.22)D and that in the SVL group was(-0.47±0.21)D,and the change in the HAL group was less than that in the SVL group,the difference was significant(P<0.001).The equivalent spherical lens degree in the HAL group was(-0.33±0.32)D and the HAL group was(-0.82±0.20)D at the 12th month,and the change in the HAL group was less than that in the SVL group,the difference was significant(P<0.001).The axial length of the eye in the HAL group was(0.09±0.09)mm and the SVL group was(0.20±0.07)mm in June,and the change in the HAL group was less than that in the SVL group,and the difference was significant(P<0.001).The axial length of the eye in the HAL group was(0.14±0.13)mm and that in the SVL group was(0.37±0.08)mm,and the change in the HAL group was less than that in the SVL group,and the difference was significant(P<0.001).Conclusion Wearing HAL lens for 12 months can effectively slow down the growth of myopia degree and axial length in adolescent myopia patients.

Qualidade de vida e visão pós-facectomia / Quality of life and vision post-facectomy

Resumo Objetivo: A catarata é a principal causa de cegueira reversível no mundo e seu tratamento é baseado em cirurgia, facectomia. A evolução do procedimento tem se baseado em vários pilares, mas é no desenvolvimento de novos tipos de lentes intraoculares que vem mostrando inovações consideráveis. As lentes atuais são capazes, além de tratar a catarata, de corrigir erros refracionais. O objetivo deste estudo foi avaliar a qualidade de vida e de visão pós-facectomia, comparando as lentes multifocais (Restor), tóricas, monofocais esféricas (SN60AT) e monofocais asféricas. Métodos: A pesquisa abrangeu 54 pacientes submetidos a facectomia com implantação de uma das lentes há, pelo menos, 3 meses. Os pacientes responderam questionário de qualidade de vida Cataract TyPE Specification sobre satisfação de visão, dependência de óculos para diversas atividades diárias e presença de fenômenos disfóticos. Para análise dos dados foram utilizados os testes de Kolmogorov-Smirnov, quanto a normalidade e ANOVA com teste de Tukey, quanta parametria. Em comparações não paramétricas, utilizou-se o teste de Mann-Whitney. Em todas as análises foi usado o mesmo nível de significância (p<0,05). Resultados: Numa escala de 0 a 10, a pesquisa mostrou que as lentes SN60AT, esféricas monofocais, foram as que obtiveram menor nível de satisfação entre as 4 lentes, obtendo média de 8,7 (DP= 1,30; IC ± 0,655), seguido das esféricas monofocais (média= 8,3 - DP= 1,83; IC ± 0,927), das esféricas multifocais (Restor) (média = 8,9 - DP = 1,42; IC ± 0,721) e as tóricas (média = 9,1 - DP = 1,67; IC ± 0,844) como a de maior nível de satisfação. Em relação à dependência dos óculos, a lente Restor foi a que mostrou melhor desempenho, com menor dependência dos óculos. Fenômenos disfóticos foram mais frequentes nos pacientes que tiveram implantada a lente SN60AT seguida de lente Restor. Conclusão: Conclui-se que as lentes SN60AT foram as lentes que causaram menor grau de satisfação, tendo os fenômenos disfóticos umas das principais queixas, associada a dependência dos óculos pós-cirurgia. Os pacientes que tiveram as lentes Restor implantadas, apesar dos sintomas disfóticos mais presentes do que as lentes monofocais tóricas e monofocais esféricas, tem o mesmo nível de satisfação, e ainda proporciona maior independência dos óculos.

Abstract Objective: Cataract is the leading cause of reversible blindness in the world and its treatment is based on surgery, facectomy. The evolution of the procedure has been based on several pillars, but it is in the development of new types of intraocular lenses that has been showing considerable innovations. Current lenses are capable, in addition to treating cataracts, of correcting refractive errors. The aim of this study was to evaluate the quality of life and post-facectomy vision, comparing multifocal lenses (Restor), toric, spherical monofocals (SN60AT) and aspheric monofocals. Methods: The study included 54 patients undergoing a facectomy with implantation of one of the lenses for at least 3 months. The patients answered questionnaire quality of life Cataract TyPE Specification on vision satisfaction, glasses dependence for various daily activities and presence of dysphothetic phenomena. For the analysis of the data, the Kolmogorov-Smirnov tests were used, regarding normality and ANOVA with Tukey's test, how much parametric. In non-parametric comparisons, the Mann-Whitney test was used. In all analyzes, the same level of significance was used (p <0.05). Results: On a scale of 0 to 10, the research showed that single-spherical spherical SN60AT lenses were the ones that obtained the lowest level of satisfaction among the four lenses, obtaining an average of 8.7 (SD = 1.30, CI ± 0.655), followed (mean = 8.9 - SD = 1.42, CI ± 0.721) and the toric (mean = 8.3 - SD = 1.83, CI ± 0.927), multifocal spherical (Restor) 9.1 - SD = 1.67, CI ± 0.844) as the highest level of satisfaction. Regarding the dependence of the glasses, the Restor lens showed the best performance, with less dependence on the glasses. Dysphasic phenomena were more frequent in patients who had implanted the SN60AT lens followed by Restor lens. Conclusion: It is concluded that the SN60AT lenses were the lenses that caused less satisfaction, and the dysphothetic phenomena were one of the main complaints, associated with the postoperative glasses dependence. Patients who had restored Restor lenses, despite the more present dysphoric symptoms than spherical monofocal and single-focal lenses, have the same level of satisfaction, and still provide greater independence of the glasses.

Changes of Deviation After the Patch and +3.00 Diopter Spherical Lens Test in Basic Intermittent Exotropia

PURPOSE: To assess the change of deviation angle after the patch test and +3.00 diopter (D) spherical lens test in basic intermittent exotropia. METHODS: The present study included 57 patients diagnosed with basic intermittent exotropia. The deviation angles at near and far before and after monocular occlusion of 40 minutes or more were measured. Afterward, change of deviation was also measured by placing +3.00 D spherical lenses at near. RESULTS: Results from the study revealed pre-occlusion mean deviation angles of 23.1 +/- 7.41 prism diopters (PD) at near, and 23.9 +/- 6.56 PD at far. After the patch test, the mean deviation angles were increased to 28.3 +/- 6.50 PD (p < 0.0001) at near, and 25.5 +/- 6.40 PD (p < 0.0001) at far. After the +3.00 D spherical lens test, the angle was increased to 31.5 +/- 7.53 PD (p < 0.0001) at near. Using the gradient method, the average accommodation convergence - accommodation ratio was 1.4 +/- 1.19 PD/D. CONCLUSIONS: Both the patch test and +3.00 D spherical lens test significantly increased the deviation angles at near and far, they helped to find the maximum deviation angle in patients with basic intermittent exotropia.
