Keratectomy

Keratectomy is a surgical operation that involves removing part of the cornea of ​​the eye (usually its superficial layer). This operation is now often performed using an excimer laser.

Keratectomy can be performed for several reasons: to correct nearsightedness, farsightedness or astigmatism; to remove scars on the cornea; for some diseases of the cornea.

During the operation, the surgeon uses a special instrument to remove a thin surface layer of the cornea with a thickness of 10 to 150 microns. This leads to a change in the curvature of the cornea and, accordingly, the refraction of the eye.

The modern method of keratectomy is photorefractive keratectomy using an excimer laser. The laser accurately removes a specified amount of tissue from the cornea without damaging the deep layers. This allows you to achieve the desired refractive effect.

After a keratectomy, a period of rehabilitation is necessary. Watery eyes, photophobia, and blurred vision may occur for several weeks. Complete restoration of vision occurs on average after 1-3 months.

A keratectomy is a surgical procedure in which part of the cornea of ​​the eye is removed. This procedure can be performed using a variety of techniques, including the use of an excimer laser, microkeratome, and microsurgical instruments.

The goal of a keratectomy is to improve vision by removing corneal defects such as keratoconus, opacities, and other irregularities of the corneal surface.

The keratectomy procedure can be performed either on an outpatient basis or in a hospital setting. It can be performed by both adults and children.

The excimer laser is the most commonly used method to remove part of the cornea during keratectomy. This method allows you to quickly and accurately remove corneal defects with minimal risk to the patient.

Microkeratome and microsurgical instruments can also be used for keratectomy, but they require a longer procedure time and a higher level of surgeon skill.

After a keratectomy, the patient may experience some symptoms such as eye redness, watery eyes, and discomfort. However, these symptoms usually go away after a few days.

Keratectomy can be an effective method for treating corneal defects and improving vision. However, before carrying out this procedure, it is necessary to conduct a thorough examination and consultation with an ophthalmologist.

Keratectomy is a surgical operation that involves removing a section of the cornea using instruments or laser equipment. In simple words, this is a method of surgical intervention for the treatment of certain pathologies of the anterior segment of the eyeball by means of its partial removal. This pathology ranks second in frequency of occurrence and occurs in 5% of patients. Treatment is carried out in three ways: using a cold knife, laser (photocoagulation), cryotherapy. It is used in ophthalmology, as it is an indispensable procedure for identifying pathological processes in the cornea.

The classic intervention is to remove part of the stratum corneum using a cold instrument. During the operation, the surgeon uses a special device to remove the required layer of tissue. This type of intervention is not used in modern medicine, as it provokes the development of complications. The modern method is the use of a laser. In this case, a section of horny tissue carefully dies to the required size; subsequently, this section falls out, and in its place a new tissue is formed that is less dense, but identical to the cornea. At the same time, as a result of the manipulation, no suture material is formed, which minimizes the possibility of infectious inflammatory processes. The infectious inflammatory process manifests itself in the form of edema. Also, the use of laser has a number of advantages: • rapid tissue healing, after which the patient can already see; • restoration occurs through the formation of new cells; • absence of pain and decreased quality of vision in the postoperative period. Today, the method of choice is laser treatment, which allows you to effectively restore visual function and have no complications during the therapy. It is necessary to understand how the procedure affects vision. The patient's fundus swells and visual acuity decreases. In addition, there is a risk of distortion and astigmatism. Keratectomy must be performed when: • the size of the lesion exceeds 8 millimeters; • glaucoma
