What is Keratoconus?

Keratoconus is a progressive disease in which the cornea takes on an irregular conical shape. The key signs of Keratoconus are a thinning of the cornea in the central or paracentral area, accompanied by an apical protrusion or elevation of the cornea’s central area and an irregular stigmatism.

All that we have said about Keratoconus can, in general, be compared to induced corneal ectasia, in which the problem has not been naturally induced but has begun after corneal trauma either spontaneously or after any type of corneal surgery and therefore the description that we give below with regards to symptoms, diagnosis, phases, treatments, etc., can be compared in general terms to this type of ectasia.

As we have the most advanced material and technology for performing them we recommend the new endonasal and endocanaliculr dacryocystorhinostomy using a laser, thanks to our acquisition of a nasal endoscope and diode laser: This surgery can be performed as an outpatient procedure at our clinic, under local anaesthetic.

Since the cornea is the main lens in the eye, vision is significantly reduced as the cornea becomes deformed. Keratoconus progression is generally slow and can be stopped in any of its phases; from slight to severe. If Keratoconus progresses the cornea bulges and thins becoming irregular, sometimes forming scars. Usually it presents in both eyes and its progressive stages are asymmetrical.

There are several treatments. The ophthalmologist will assess which is most appropriate for each patient.

  • Intracorneal rings. These are implanted inside tunnels made in the cornea. The creation of these tunnels can be performed using traditional surgery or a new technique that uses the femtosecond laser, providing greater safety and accuracy to the surgery. They are specially indicated for patients, of any age, with non-advanced disease and poor tolerance to contact lenses.
  • Cross-Linking. This is based on creating new joints or bridges between the corneal collagen fibres (it is like transforming vertical fence posts into an interlaced network) until significantly increasing the rigidity of the cornea. In this way the cornea resists ocular pressure, does not bedome deformed and therefore damage to the vision is stopped.
  • Cornea transplant. This surgery consists of substituting the unhealthy cornea for another healthy cornea, due to major corneal damage.
