Keratome: an instrument for cutting the cornea of ​​the eye

A keratome is an instrument used to cut the cornea of ​​the eye. It is used in surgical procedures to create thin, even cuts in the cornea. There are several types of keratomas, including manual and electric.

The simplest type of keratome is a flat triangular blade attached to a base - a handle. Both sides of this blade are very sharp and converge at the end to one point. Manual keratomes require an experienced surgeon and may be less precise than electric keratomes.

Electric keratomes have vibrating or rotating blades that create more precise and even cuts. They can also be adjusted to specific incision depths, making them more predictable and safer for the patient.

Keratomas are used in various surgical procedures such as keratomileusis, in which the top layer of the cornea is removed to correct visual problems such as keratoconus or acute keratitis. Keratomas can also be used in corneal transplantation, in which a diseased cornea is replaced with a donor cornea.

Although keratomas are an integral part of many eye procedures, they can also pose certain risks. Improper use of a keratome can damage the cornea of ​​the eye, which can lead to vision loss. Therefore, the use of keratomes should only be performed by experienced surgeons who have received appropriate training and have sufficient experience.

In conclusion, keratomas are an important tool in eye surgery that allows the creation of thin and even incisions in the cornea of ​​the eye. They can be manual or electric and are used in a variety of surgical procedures. But, like any surgical instrument, keratomas should only be used by experienced surgeons to minimize risks to the patient.

A keratome is an instrument used to cut the cornea of ​​the eye. It is a flat triangular blade that is attached to a handle base. Both sides of the blade are very sharp and meet at one point at the end.

Electric keratomes may have vibrating or rotating blades that allow for more precise and safe cutting of the cornea.

Keratomas are used in ophthalmology to perform various operations, such as vision correction, cataract removal, glaucoma treatment, etc. They can also be used to diagnose corneal diseases.

However, using keratomas can be dangerous if not used correctly. For example, if a keratome is used incorrectly, eye tissue can be damaged, which can lead to serious consequences. Therefore, before using keratomas, it is necessary to undergo appropriate training and obtain permission from an ophthalmologist.

An eye keratome or laser keratome is a medical device for creating an individual profile of the cornea for its various pathologies. It allows you to painlessly and quickly form a person’s cornea so that it allows both eyes to see perfectly and preserves vision for later life. If initially it was possible to see with only one eye, then after replacing the cornea, a person gains vision with both eyes at the same time. Also, from using a keratome laser until the onset of normal vision, the recovery period is reduced - to several hours, and not months, as before.
