“…Some authors use waves between 3 and 5 cm, while others consider those up to 10 cm. The ultrasound scanning technique uses a 50 Hz pulse frequency (noncontinuous) with a 1 MHz carrier frequency to penetrate about 15 cm [ 18 ].…”

Ultrasonic waves are mechanical waves with a frequency greater than 20,000 Hz. Ultrasonic waves are emitted by devices that are used in industry or that have a medical or aesthetic purpose. There is growing interest in the effect of ultrasound absorption on the human body, since people’s exposure to these acoustic waves has increased considerably in recent years. There are more and more devices that emit ultrasounds used for different sanitary procedures, aesthetic treatments and industrial processes, creating more possibilities of ultrasound noise, and therefore an increased risk of occupational hazard and occupational danger. Experiments on animals have shown damage to internal organs from receiving different ultrasonic frequencies. The main task of this work was to organize and summarize recent studies on ultrasound to reflect the current state of this technique and establish a systematic basis for future lines of research. This work has allowed us to better understand the unknown field of these high frequencies of sound, and highlights the need to carry out more studies on the ultrasound emissions that can be absorbed by the human body to determine how this energy could affect humans by calculating the maximum dose of exposure and developing manuals for the use of ultrasound-emitting equipment to protect the health of workers and all people. It is necessary to develop regulations by public administrations to improve the protection of workers, health professionals, patients and all people in general for better occupational safety, indoor environmental quality and environmental health.

“…Our body is made up of a superposition of tissues whose thickness and composition varies significantly according to sex and age. It would be interesting to carry out studies in which this is considered in order to better control the doses to be applied in therapeutic treatments [ 6 , 14 , 15 , 16 , 17 , 18 ].…”

“…The U/S waves used in ultrasound are of very low intensity (10-50 mW/cm 2 ) in order to avoid changes in the media through which they pass [22]. In physiotherapy, the frequencies used are in the range of 0.5 to 5 MHz, and the maximum power flux value specified is 3 W/cm 2 [29]. The exact energy reaching the target tissue is not known, so it is not possible to determine dose-response curves.…”

Phacoemulsification: Proposals for Improvement in Its Application

2021

A cataract is defined as opacity of the crystalline lens. It is currently one of the most prevalent ocular pathologies and is generally associated with aging. The most common treatment for cataracts is surgery. Cataract surgery is a quick and painless process, is very effective, and has few risks. The operation consists of removing the opacified lens and replacing it with an intraocular lens. The most common intraocular lens removal procedure that is currently used is phacoemulsification. The energy applied in this process is generated by ultrasonic waves, which are mechanical waves with a frequency higher than 20 kHz. A great deal of research on the different ways to perform the stages of this surgical procedure and the analysis of the possible side effects of the operation has been published, but there is little information on the technical characteristics, the intensities applied, and the use of ultrasound-emitting (U/S) equipment for cataract removal. More studies on the method and depth of absorption of ultrasonic waves in our visual system when performing the phacoemulsification procedure are needed. It would be advisable for health authorities and medical professionals to develop guidelines for the handling and use of ultrasonic wave-emitting equipment, such as those that exist for ultrasound and physiotherapy. This could help us to reduce undesirable effects after the operation.

“…La función del ultrasonido en la reducción de la grasa, se basa en un efecto llamado cavitación, donde los pulsos de ondas ultrasónicas crean ondas de compresión que dentro de los adipocitos generan pequeñas burbujas, las cuales pueden ser estables ya que se expanden y contraen de forma rápida o bien las inestables, que se expanden de tal manera que llegan a un límite e implotan rompiendo la estructura celular y liberan su contenido con los restos celulares al espacio intracelular 2 .…”

Aunado a los factores patológicos, existe un trastorno estético, ya que no es posible disminuir la adiposidad localizada en el abdomen a través de dietas, sino requiere de unos tratamientos complementarios 2 .…”
