Keratoconus

Keratoconus is a progressive disease of the cornea caused by a congenital defect of the collagen structure which can lead to a significant deterioration in vision.

What’s the problem?

The cornea
Keratoconus

becomes thinner and bulges when affected by keratoconus, leading to a significant deterioration in vision. The course of the disease is linked to a gradual increase in astigmatism (cylindrical dioptres) and often results in changes to spherical dioptres
In advanced stages, these dioptres are very difficult to correct using eyeglasses. Modern medicine has so far been unable to cure keratoconus completely, but it is able to slow it down or halt its progress.

Keratoconus

What treatment is available for keratoconus?

Today, many more options are available for treating keratoconus than in the past, and whether they are suitable or not depends on the stage of the keratoconus.
SCLERAL CONTACT LENSES
SCLERAL CONTACT LENSES

If diagnosed early, keratoconus can be corrected by the application of special contact lenses which can alter the irregular shape of the cornea by creating pressure on it, or forming a “new surface” of the cornea, which improves vision.

These contact lenses do not cure the disease, but at least slow down its progress.

  • The scleral contact lens touches the white of the eye and forms a space filled with liquid on the cornea without touching it
  • The liquid between the lens and the cornea reduces the irregularity of the cornea thus ensuring an even refraction of light into the eye
  • Each scleral contact lens is made to measure for the patient

CROSSLINKING
CROSSLINKING

At present, keratoconus is most often stabilised using the crosslinking (CXL) method. In our clinic, we use a modern method to treat keratoconus: accelerated crosslinking. This consists in irradiating the corneal tissue with a UV-A lamp and applying a riboflavin solution. In five minute – or shorter – intervals, we apply drops of the riboflavin solution onto the cornea until it is saturated as required. We then continue to irradiate it with a UV-A for 10 minutes. The whole procedure takes approximately 60 minutes.

  • After crosslinking, the eye can be photophobic for 2 to 4 days.
  • The procedure can be carried out by removing the epithelial part of the cornea, or by keeping it.
  • If the epithelial part of the cornea is removed, the patient can experience eye watering and the sensation of sharp pain in the eye.

INTRASTROMAL CORNEAL RINGS
INTRASTROMAL CORNEAL RINGS

The treatment of keratoconus by crosslinking can also be combined with instrastromal corneal rings implants (keraring).
This is a technique where one or two curved segments/•• are implanted, after shaping a tunnel in around 80% of the thickness of the cornea. The number and shape of the segments is calculated especially for each patient. Ring implants even out and stabilise the cornea.
A secondary effect can be an improvement in vision.

  • The whole procedure takes around 15 to 30 minutes
  • We use a femtosecond laser to make the tunnels needed to implant the corneal rings
  • After the procedure, a contact lens is placed on the cornea
  • The eye can be photophobic for 2 to 4 days.

    Equipment and instruments

    • FEMTOSEKUNDOVÝ LASER VICTUS
      Victus Femtosecond laser

      Victus Femtosecond laser

      FEMTOSEKUNDOVÝ LASER VICTUS

      The UVEA Mediklinik is the first and only clinic in Slovakia which has a combined Victus femtosecond laser from the German company Technolas PV.

      The advantage of the Victus laser is the high precision and care for the eye tissues. Certain types of procedures can be performed entirely without the eye being touched by the instrument, but only by the laser ray. Technolas PV has chosen the UVEA Mediklinik eye clinic as its reference and training centre.

      What can this device do?

      LRCS

      Enables surgical procedures to be performed with high precision for cataract operations. The laser performs a capsulorex and lens fragmentation very precisely and safely.

      INTRACOR

      A surgical method which corrects worsened vision close up, by creating micro circles in the corneal stroma, thus achieving the curve of part of the cornea and correcting the eye’s optic system.

      CUSTOMFLAP

      Creating a corneal flap during LASIK surgery

      CUSTOMSHAPE

      Therapeutic procedures on the cornea such as ceratoplastics, tunnels for corneal rings and astigmatic keratotomy.

      The Amaris 750 S laser by the German company Schwind us currently one of the fastest and best excimer lasers in the world.
      Standard excimer laser systems work with a speed of 200 to 400 Hz, the Amaris has a speed of 750 Hz.

      What are the advantages of our laser?

      1050x

      It follows eye movement 1,050 times per second and corrects the aim of the laser ray.

      Extremely precise

      correction of short-sightedness, astigmatism and far-sightedness.

      It contains

      one of the most modern systems for controlling the eye’s rotational and torque movements.

      Online pachymetry

      means measuring the thickness of the cornea in real time during eye surgery.

      The device by the Amercian company Lightmed was developed for corneal cross-linking. The smooth density setting of the UV-A lamp, enables the application time of the corneal irradiation to be reduced. This is so-called accelerated cross-linking. In addition, it is equipped with a pulse regime which offers an opportunity for new treatments of corneal diseases.
