Keratotomy (Keratototu)

Keratotomy (Keratotomy) is a surgical procedure that is used to correct certain types of refractive errors of the eye. This procedure involves making incisions in the cornea of ​​the eye to change its shape and therefore improve the patient's vision.

Keratotomy can be used to correct astigmatism, which is one of the most common refractive errors of the eye. Astigmatism is characterized by image distortion caused by the irregular shape of the cornea or lens of the eye. As a result, vision may be blurred or distorted.

One form of keratotomy is radial keratotomy. In this procedure, small incisions are made in the cornea along its radius to change its shape and improve vision. Radial keratotomy was widely used in the past, but is now usually replaced by more modern vision correction methods such as laser vision correction.

Although keratotomy is considered a safe procedure, like any surgical procedure, it can have risks and complications. Possible complications may include infection, bleeding, corneal detachment, and blurred vision. Therefore, it is important to discuss all the risks and benefits of the procedure with an experienced ophthalmologist or surgeon.

In conclusion, keratotomy is one of the vision correction techniques used to improve the vision of patients with certain types of refractive errors of the eye. Although radial keratotomy was widely used in the past, more modern vision correction methods such as laser vision correction are generally preferred today.

Keratotomy is a surgical procedure to cut the cornea of ​​the eye to correct various corneal pathologies. This is one of the most common treatments for keratoconus, keratoglobus, keratoiridodystrophy and other corneal pathologies that can lead to vision impairment.

Keratotomy can be performed both on the surface of the cornea and in its depth. In the first case, an incision is made on the surface of the cornea and allows you to correct its shape and the shape of the lens inside the eye. In the second case, an incision is made deep into the cornea, which allows you to change its shape, structure and curvature.

One of the most common keratotomy techniques is radial keratotomy. It consists in cutting the cornea into radial lines, each of which corresponds to a specific angle of vision. Thus, after the operation the patient can see better than before it.

In addition, there are several other techniques for performing keratotomies, such as circular keratotomy, semicircular keratotomy and others. Each of them has its own advantages and disadvantages, so the choice of technique depends on the specific pathology of the cornea and the individual characteristics of the patient.

In general, keratotomy is an effective treatment method for many pathologies of the cornea, which can improve the patient’s vision and quality of life. However, like any operation, it has its risks and can cause complications. Therefore, before undergoing a keratotomy, it is necessary to carefully study all possible risks and benefits, and discuss them with your doctor.

A keratotome (kerry-tome) is a special cutting instrument that allows during surgery not only to cut off a corneal flap, but also to dissect it into several parts at once. This approach, combined with careful intervention planning, achieves the best results. They are most accurately visible when performing a resizing operation.
