KERATOCONUS

The treatment of keratoconus is anything but easy. The available techniques either achieve its stabilization, i.e. halting the progressive evolution, or partial restoration of the patient's vision.

Cross-Linking

Recently it has been possible to stabilize keratoconus using the Cross-Linking treatment. Cross-Linking uses photoreactive agents, such as riboflavin in conjunction with UV-A rays. It is a modern, therapeutic method based on molecular linkage of corneal collagen fibers, in order to halt the progression of keratoconus.

The typical procedure takes about one hour. In the first 30 minutes the instillation of the photosensitive agent (riboflavin) is performed, and then UV-A rays are applied (Dresden Protocol).

At the Ophthalmological Institute ‘Diathlasis’ the most advanced machine (AVEDRO Accelerated Cross-linking KXL) is used to treat keratoconus, completing the treatment in 3 minutes instead of 30 required when using the previous method.

The AVEDRO is the most advanced system for the interconnection of corneal collagen (Cross-Linking) and it has reduced treatment time. This process is achieved by using higher power efficiency, increasing UV-A energy, and reducing the exposure time to the absolute minimum, at just three minutes.

It is performed in our clinic easily and pain-free. With this treatment, the cornea becomes less elastic, resulting in the stabilization of the keratoconus, and in some cases, in the improvement of the patient’s night vision.

With this method, we can avoid the evolutionary development of these pathologies that, if not treated, can lead to the need for corneal transplantation.

Intrastromal rings (KERARING)

At the Ophthalmological Institute ‘Diathlasis’ the insertion of interlamellar rings (Kerarings) using Femtosecond Laser is used.

These are tiny inserts, placed on the corneal layer’s periphery, changing its shape. This way help avoid any pathological deformation of the cornea, resulting in improved vision.

The process of inserting the interlamellar rings is carried out under local anesthesia, using the Femtosecond Laser technique and lasts about 5 minutes. With these rings the cornea surface is stabilized, improving vision with eyeglasses.
Results in vision can be noticed in less than 24 hours after procedure.

Keratoconus Contact Lenses Application Department

The Ophthalmological Institute ‘Diathlasis’ has its own special Keratoconus Contact Lenses Application Department, in order to improve a patient’s vision.
Patients with keratoconus that have either undergone stabilization treatment, or not, may use special keratoconus contact lenses. These lenses improve the patient’s vision, but do not ensure stabilization of the keratoconus.

PRK-CXL

Since the corneal thickness is such as to allow for tissue photoremoval for its normalization, the Cross-Linking can be combined with PRK phototherapeutic keratectomy, in order to improve a patient's vision using glasses.
