Keratoconus is a progressive corneal disease in which the cornea gradually thins and becomes cone-shaped. This leads to the development of irregular astigmatism and a gradual decrease in visual acuity. Patients' glasses and contact lenses become unsuitable.
Modern, high-tech equipment from leading global manufacturers is used to diagnose and treat keratoconus.
For early detection of the disease, the Sirius (Schwind) optical corneal analyzer is used. It allows for a detailed assessment of the shape, curvature, and thickness of the cornea and detects signs of keratoconus even in the earliest stages.
Treatment methods include:
During the procedure, the cornea is treated with a special riboflavin (vitamin B2) solution and irradiated with ultraviolet light. This strengthens the cornea's collagen fibers, increasing its strength and stabilizing its shape.
A thin tunnel is created in the middle layer of the cornea (stroma) using a high-precision femtosecond laser. One or two corneal segments made of biocompatible material are then implanted into the tunnel.
The segments provide additional support for the cornea and help reshape it. As a result, the central part of the cornea becomes more even, irregular astigmatism and myopia are reduced, and vision is improved.
In some cases, combination treatment, using the above methods sequentially, is used to achieve the best results. The choice of treatment sequence depends on the stage of keratoconus, the thickness and shape of the cornea, and the individual characteristics of the patient's eye.
Keratoconus treatment is performed on an outpatient basis and does not require hospitalization. A complete examination is performed before the procedure, after which the doctor determines the optimal treatment strategy.
After a course of treatment and stabilization of progressive keratoconus, optical correction is necessary. In addition to fitting glasses and contact lenses, the clinic implants additional phakic intraocular lenses, which correct visual acuity in patients with complex astigmatism and large differences in optical characteristics between the eyes. The lenses are individually selected and ordered for each patient. Implantation takes just a few minutes and allows the keratoconus patient to fully recover from surgery without the need for glasses.
All procedures are performed under local anesthesia. The patient experiences no pain and can return home the same day. After the procedure, the doctor provides detailed recovery and follow-up recommendations.
Surgical procedures are performed using the Zeiss Femto LDV femtosecond laser system, which allows for the formation of intraocular tunnels with micron precision and ensures a high level of safety and predictability.
The Ophthalmology and Microsurgery Department at K+31 Clinic provides comprehensive diagnostics and treatment for patients with various stages of keratoconus. We use modern methods that help stop the progression of the disease, improve the shape of the cornea, and enhance vision.

About the disease
According to recent scientific research, the disease occurs due to a combination of genetic predisposition and external factors; the exact cause remains unknown.
Main risk factors:
The disease usually begins in adolescence or young adulthood (15–35 years) and affects both eyes, although one may be more severely affected. Without treatment, vision deteriorates over time.
The main symptoms of keratoconus are:
The K+31 Ophthalmology and Microsurgery Department uses modern diagnostic and treatment methods for keratoconus, which are individually tailored to each patient.
