Satisfação de pacientes submetidos à cirurgia refrativa de PresbiLASIK / Satisfaction of patients submitted to PresbyLASIK refractive surgery

Resumo Objetivos: Avaliar a satisfação dos pacientes submetidos à cirurgia de Presbilasik central e determinar a prevalência de sintomas relatados após a cirurgia. Métodos: Este é um estudo descritivo, observacional, transversal, com dados obtidos de pacientes submetidos previamente ao PresbiLASIK. Resultados: A amostra consistiu de 45 pacientes, com média de idade de 57,7 (±7,19) anos. A nota média atribuída para a satisfação visual com o procedimento foi 8.9 (±1.0). A qualidade visual após a cirurgia foi classificada como igual ou melhor que a esperada por 84,5% dos pacientes e 31% apresentaram sintomas noturnos, como halos e raios de cometa. Conclusão: A qualidade de visão após o procedimento de PresbiLASIK foi altamente satisfatória para os pacientes. Fator determinante dessa satisfação é o processo de manejo das expectativas pré-operatórias dos pacientes, informando das possibilidades terapêuticas disponíveis, e, no caso da escolha cirúrgica, acerca das vantagens e limitações.

Abstract Objectives: Toassess the satisfaction of patients undergoing central Presbilasik surgery and to determine the age of patients who undergo PresbiLASIK and the prevalence of symptoms reported after surgery. Methods: This is a descriptive, observational, cross-sectional study with data collected from patients previously submitted to PresbiLASIK. Results: The sample consisted of 45 patients, with a mean age of 57.7 (±7,19) years. The average score attributed to visual satisfaction with the procedure was 8.9 (±1.0). Visual quality after surgery was classified as equal to or better than expected by 84.5% of the patients and 31% complained of nocturnal symptoms such as halos and comet rays. Conclusion: The quality of vision after the PresbiLASIK procedure was highly satisfactory for the patients. A determining factor for this satisfaction is the process of managing patients' preoperative expectations, informing them about the therapeutic possibilities available, and, in the case of surgical choice, about its advantages and limitations.

Presbyopia: Prevalence; Distribution and Determinants in Owerri; Nigeria

Background: Presbyopia causes blurring and impairment of vision at near. It is the most common physiologic change in the adult eye with advancing age. Good near vision is a necessity for domestic activities; office work and near vision tasks other than reading and writing; especially among adults in a resource-limited economy. The study determined the prevalence; distribution and determinants of presbyopia; presbyopic spectacle coverage; and provided data for ready-made near vision spectacles in Imo State; Nigeria. Materials and Methods: A total of three thousand; four hundred and fifty-one adults consisting of 2606 persons as study group and 845 persons as controls were randomly selected for the study. Structured questionnaire was administered to the subjects. Their visual acuity at far and near including tonometry; ophthalmoscopy; perimetry; retinoscopy and subjective refraction were done. Subjects who could not read N6 and emmetropes; who are 40 years and above were considered as presbyopic. Results: The prevalence of presbyopia was 70.9 and 75.0 of study and control groups respectively. Females aged 40-49 were in the majority (57.1 and 51.9 of females in the study and control groups respectively). Subjects requiring additions at near of ?+1.50DS to 2.00DS were in the majority (39.0 and 46.4 of study and control groups respectively). Amongst the presbyopes 61.3 and 78.7 of study and control groups respectively did not have presbyopic correction. The subjects were also ignorant of corneal inlay technology in treatment of presbyopia. A higher prevalence exists among rural dwellers and the contributory factors were environmental influences; poor nutrition and irrational use of chloroquine for treatment of malaria. Conclusion: Over seventy-percent of presbyopia was found in this study. The determinants were age; gender; nutrition and drug use. Majority of the presbyopes were domicile in the rural area and did not have corrective spectacles. We recommend visual health education; regular vision screening and intervention to achieve the targets of vision 2020 in low-and-medium-income countries

Epidemiological aspects of visual impairment above 50 years in a rural area.

A cross-sectional survey was conducted in 5 villages in central India to find out the extent, causes and epidemiological factors for visual impairment among 903 individuals aged above 50 years; 44.3% of them were visually impaired (29.4% with low vision and 14.9% blind). Age-specific visual impairment increased at a rate of 13.2% with each decade of advancing age. Landless labourers suffered more from visual impairment than other occupational groups (p < 0.05). Socioeconomic and literacy status of the population did not significantly influence the prevalence of visual impairment. Major causes of visual impairment were cataract (48.5%), refractive errors (24.5%), age-related macular degeneration (10%), glaucoma (6.8%), and others (10.2%). In view of the high prevalence of visual impairment among the elderly individuals, it is necessary to intensify our efforts in motivating them for early detection and treatment.
