Aging populations are increasing as the population is rapidly aging. In particular, one of the most sensitive parts of the body, the eyeball is a problem because it often causes diseases such as cataracts due to presbyopia.

Presbyopia refers to a condition in which the function of the lens decreases due to aging of the body, and thus it is unable to focus at close range. It usually occurs after the age of 40, but in modern times, the number of cases occurring around the 30s is gradually increasing due to frequent short-term work such as the use of mobile phones and PCs.

Ultrasound is an acoustic pressure wave having a frequency above a human hearing range (16 Hz to 20 kHz), and is a form of mechanical energy transmitted through biological tissue. Currently, therapeutic ultrasound is used in various ways according to the purpose, purpose, and characteristics of treatment using three physical effects: mechanical effect, resonance effect, and thermal effect.

The treatment device or method using ultrasound has the advantage that it can be performed non-invasively without surgical procedures and has a fast recovery time, so it is actively spread not only in Korea but also worldwide.

However, the structure or shape of the human eye is slightly different for each individual, and in order to treat a lens in which presbyopia is a problem by irradiating therapeutic ultrasound, greater precision and technology are required. Currently, various medical ophthalmic ultrasound treatment techniques have been disclosed in the medical market, but even the existing technique has been insufficient in presenting treatment devices based on accurate data for each lens.
