Schweigger Iris-Tweezers

Schweigger Iris Pinzet is a German ophthalmologist born in 1861. He was one of the first researchers of the eye and its diseases. Schweiger studied diseases of the retina and vitreous body. He also developed a method for diagnosing visual impairment using special tests.

Schweigger became famous for his work on the study of the eyeball. He studied various aspects of the anatomy and physiology of the eye, and also developed new methods for treating eye diseases. He also studied problems associated with myopia and farsightedness.

One of Schweigger's most significant discoveries was the invention of a method for diagnosing visual impairments, which he called “iris tweezers.” This method involves using a special instrument that allows you to examine the condition of the cornea and lens of the eye.

In addition, Schweiger developed a new method for treating myopia, which involved changing the shape of the cornea of ​​the eye. This method was called the “Schweiger method” and became one of the most effective methods for treating myopia.

Although Schweigger died in 1942, his contributions to ophthalmology remain significant and continue to be used to this day. His methods for diagnosing and treating eye diseases, as well as his studies of the anatomy and physiology of the eyeball, became the basis for many subsequent research and developments in the field of ophthalmology.

Schweigger is a method of obtaining correct vision. The method is based on the use of acetic acid or ammonia vapor (NH3) to soften the lens of the eye. These vapors are inhaled through a cotton swab, which is placed on a finger in the nasal passage. After this, you need to inhale and exhale for 5 seconds. Inhalation of acid vapor causes excitation and contraction of the ciliary muscles, and then a slight bulging of the lens. With regular use of the method, the lens becomes more elastic, and the patient can see well even at night. Schweigger's first patent was issued in 1869. The procedure is still popular today.
