Tecnología virtual para operar ojos

El servicio de Oftalmología del Hospital de León utilizes a simulador chirúrgico digital to prepare its six medical residents (MIR). Los oftalmólogos que se forman en la unidad docente de Oftalmología del Hospital de León, accredited to receive two residents a year, se preparan estos días en abilidades con el stimulador cúrúrgica prior to the start of surgery on the patient. La especialidad de Oftalmología has a duration of 4 years and currently there are six residents training in the service.

The technology with which the future specialists are trained before the operation and the patient recreates three-dimensional virtual environments that allow training in diverse surgical techniques, some of great complexity, with realism and interactivity. «The training

the oftalmólogo en formation with the surgical simulator prior to the start of the surgery on the patient has demonstrated a global reduction of complications up to 50%; and ahorro significantado en los tiempos chirúrgicos; and minor surgical trauma (reducción en la potencia de ultrasonidos que se emplean durante cataract surgery) lo cual mejora la recuperación postsurugía y reducción de errores en uno de los pasos críticos de la surgery, hasta three veces menos frecuentes un failo al iniciar de la intervención con el entrenamiento previo en simulador”, explains the head of the Oftalmología del Caule service, Manuel Franco Benito.

El simulador entraina a los Oftalmólogos en dos intervenciones. Cataract surgery, which is the most reproducible, can be selected in different degrees of complexity – simple or complicated cataracts – at the same time that it is practiced in the intraocular lens implantation technique and the second type of prosthesis. La segunda ciurgía en la que se adquiere formación son las intervenciones de vitreo-retina, mainly haemorrhages vitreas y desprendimientos de retina.

The residents of the three first years are trained mainly in the cataract module and those of the last two years in the cataract module and vitreo-retina surgery.

El Hospital de León realized an average of 3,428 annual interventions in the years 17, 18 and 19. «This year they are doing 21% more cataract surgery than the average of the last few years before the pandemic. En la pandemia se dejaron de hacer casi 2.000 cirugías, 1.350 cataratas aproximatena». Franco Benito assures that the rest of the surgeries that they do in the service are vitreo-retina, with 250 interventions per year. “Estas operations no se interruptieron durante la pandemia por ser una patología preferente y urgente y no hay lista de espera porque se programan al ser diagnosados”.

El simulador evalúa de forma continua la precisión y eficacia de las maneuveras cirúgirás realizados. Gracias a la simulación virtual, el médico en formationa puede familiariserse con el uso del microscope chirúrgico y perfeccionar las tecniques chirúrgica más novedosas.

“Las nuevas estrategies de formationa y la búsqueda de minimizar until donde sea posible la iatrogenia (daño no deseado nor soughta para la salud) associated with the inexperience of young ophthalmologist surgeons, from the Ophthalmology service at the Hospital de León we have contacted a casa comercial (Johnson & Johnson) and the Universidad privada Francisco de Vitoria para que podamos contar hasta el 9 de noviembre con dos equipos Eyesi® de simulación surgical. El curso consiste en un modulo de conocimientos teóricos sobre ciurgía que ha de ser superado antes de iniciarse en la fase ciurígura. The activity realized and the skills achieved by each resident with the simulator are registered on the platform from the day it is done and followed by each student. Finally, from the Universidad Francisco de Vitoria, the level of competence reached and the hours of simulation will be accredited. The direction of the course depends on the head of the Ophthalmology Service of the Hospital de León and their tutors Irene Garzo, Carolina García, Jorge Sánchez and Carlos Plaza, oftalmólogos del servicio». Franco Benito assures that the initiative “which combines the effort of an Ophthalmology service with private entities like a commercial house of great prestige and a modern university, siendo estos ultimos los que han made the economic effort to invest in very expensive equipment that, at least a día de hoy en nuestra especialidad, la sanidad pública no está adquiriendo».

The technology of simulation with virtual reality «historically, it is used in professions that require a comprehensive training, such as aeronautics and railroad transport, for example. It is demonstrated that the training of airline pilots with simulators saves time and improves skills».
