Polyaka corneal tweezers: an important tool for vision correction
Polyaka corneal forceps are one of the most important instruments in ophthalmology, providing access to the surface of the cornea to perform various procedures and surgical interventions. It was invented in 1964 by the Belarusian scientist Dmitry Dmitrievich Polyak, who is known for his research into eye diseases and methods of treating them.
The benefits of Pole's tweezers
Like any other tweezers, Polyaka is used to grasp and hold various objects, in this case, for operations on the surface of the cornea and removal of excess cells or foreign bodies. Without Polyak's tweezers, operations on the cornea would be extremely difficult and risky, since when using conventional tweezers there is a risk of injuring the corneal tissue and leading to complications.
Subsequent experience using Polyake tweezers spoke of the following advantages of its use:
- Increased accuracy and safety of operations and procedures. Pole's tweezers have a special head shape that allows the doctor to exercise precise and accurate control over the operated area of the cornea.
- Easy to use. Unlike classic tweezers, the pole is in a comfortable position, allowing you to hold it even with one hand. The instrument is also easy to sterilize and does not cause problems during procedures.
Application of pole tweezers
The purpose of this type of instrument cannot be imagined without knowledge of the physiology of the eye. The cornea is the transparent part of the eye that protects the internal structures from external influences and is involved in the refraction of light rays. The cornea is a kind of lens and performs its function with the help of many protein molecules that are located very tightly to each other. Thanks to these molecules, the cornea is able to change the curvature of the plane while focusing light on the retina.
One of the aspects of ocular physiology that is most susceptible to damage is the corneal surface. Its delicate tissue requires special care during manipulation, as a result of which it is extremely difficult to perform a surgical operation with ordinary tweezers, and in some
