Resumo
Objetivo: O objetivo primário deste estudo foi confeccionar um dispositivo para acoplamento de smartphone ao microscópio com lâmpada de fenda por meio de manufatura aditiva, para fotodocumentação de estruturas oculares. Métodos: Utilizamos como método o estudo transversal com o objetivo de analisar a adaptação do modelo de dispositivo de fabricação própria nos aparelhos oftalmológicos mais utilizados atualmente (microscópios e lâmpadas de fenda). Para a captura de imagens com o dispositivo desenvolvido, utilizamos um fundo branco a fim de provar a qualidade do registro. O protótipo em estudo pode ser acoplar smartphones aos aparelhos oftalmológicos e foi avaliado após o teste por quatro médicos oftalmologistas por meio de questionário. Resultados: O novo dispositivo foi feito em impressão em 3 dimensões (3D), com manufatura aditiva. Com relação à captação de imagem feita pelo dispositivo acoplado aos aparelhos oftalmológicos, três avaliadores relataram não perceber diferença entre o dispositivo em estudo e os outros dispositivos existentes no mercado. O quarto avaliador indicou que, usando o dispositivo em estudo, conseguiu capturar a imagem do olho examinado em um tempo menor ao dos dispositivos já existentes. No que se refere à adaptação do dispositivo na lâmpada de fenda, todos os avaliadores responderam que é facilmente acoplável e ajustável. No que tange à segurança do uso do dispositivo na lâmpada de fenda, todos os avaliadores indicaram como sendo seguro. Ao serem questionados se o dispositivo pode ser uma opção aos já existentes, todos os avaliadores responderam que sim. Conclusão: Este estudo possibilitou a confecção do protótipo de um dispositivo adaptador, por meio da manufatura aditiva em impressora 3D, para uso de smartphones para a fotodocumentação de exames oftalmológico realizados com lâmpada de fenda. O protótipo estudado se mostrou eficiente no quesito centralização adequada da imagem, devido à possibilidade de ajuste dos eixos X, Y e Z, facilitando a documentação em vídeo e a fotografia das alterações oculares encontradas durante a realização de exames oftalmológicos.
Objective: The primary objective of this study was to manufacture a device for coupling a smartphone to a microscope with a slit lamp through additive manufacturing, for photodocumentation of ocular structures. Methods: A cross-sectional study to analyze the adaptation of the self-made device model in the most commonly used ophthalmic devices (microscopes and slit lamps). The image capture was done with a white background to prove the quality of the image captured by the camera of the developed device. The prototype under study can be attached to smartphones and ophthalmic devices and was evaluated by four ophthalmologists through a questionnaire. Results: This device was made in 3D printing (3D), with additive manufacturing. Regarding the image capture performed by the device coupled to the ophthalmic devices, three evaluators reported not seeing any difference between the device under study and other devices currently on the market. The fourth evaluator reported that, using the device under study, he was able to capture the photograph of the examined eye in a shorter time. Relative to the adaptation of the device to the slit lamp, all evaluators responded that the device can be easily attached and adjustable. Concerning the safety of using the device in the slit lamp, all rated it as safe. When asked if the device could be an option to the existing ones, all the evaluators agreed. Conclusion: This study made it possible to make a prototype of an adapter device, through additive manufacturing in a 3D printer, for the use of different smartphones for the photodocumentation of ophthalmic exams performed with a slit lamp. The prototype studied proved to be efficient in terms of adequate image centralization due to the possibility of adjusting the X, Y and Z axes, facilitating video documentation and photography of ocular alterations found during ophthalmological examinations.
