Cornea cone correction

Table of Content

Keratoconus is a  progressive  cornea dystrophy  resulting from  inborn metabolic disorders.

In  treatment,   hard contact lenses are used mainly as well as  cross-linking,  intacorneal  rings ( INTAX, CXL, CCL) and corneal transplants.

Currently, the lenses produced are highly sophisticated and complex product, both in terms of  the optical and structural aspect.  Available in our consulting room, we  apply a  matching method using specialist software and high-resolution video keratograph , which  ensures unprecedented comfort of hard contact lenses and excellent vision. There are all the known geometries of the lenses. Lens can be designed on the basis  topography, made individually for each patient,  ensuring high safety and convenience in wearing  hard contact lenses.

How to perform cross-linking?

Cross-linking is a procedure aimed at  strengthening  the cornea and reconstructing  the bonds among  the lamina of the cornea.  Damaged connections between these structures significantly weaken the cornea, which  leads to the deformation, thinning and bulging , resulting in the development of keratoconus.

The procedure is performed under local anesthesia and corneal epithelium is removed first. Next, the  eye is instilled with riboflavin at intervals of several minutes , then a special lamp emitting ultraviolet light irradiates the cornea  for 30 minutes. During this time, cross bonds between cornea stroma lamina are produced.

Applying  this method, you can largely reduce the development of the disease, or even stop it completely. Cross-linking, contrary to expectations, does not improve vision and it is still necessary to wear hard contact lenses, however ,  the treatment helps  to avoid progression of the disease and cornea  transplant in the future.

INTAXES (intra-corneal rings)

The method of intra-corneal ring implantation  (INTAX or Intacs or INTAKS) was originally developed for the correction of myopia and minor  astigmatism. However, it did  not become popular. . Due to the mechanism of action, the tendency for stretching the central part and stabilization of the  cornea, this method was  proposed to be used  for the corneal cone. According to the manufacturer’s instructions, INTAXES  should be used by  people who can not wear or absolutely do not tolerate hard lenses. This method does not inhibit the progress of the disease. It is not possible to achieve such a good a vision as with contact lenses. Nevertheless, it  allows to improve the vision according to the above-mentioned indications and postpone the moment  of cornea transplantation , which is to be performed due to  refractive indications . If possible, we suggest combining both procedures – INTAX implantation and   Cross-linking.

Cornea transplantation

Cornea transplantation  is the  absolutely  last resort in the treatment of keratoconus.  It  can be performed   as transmural  – penetrating ( entire thickness of the cornea, all its layers are transplanted) or layer transplantation ( the outer layer of the cornea is removed , leaving the so-called. Membrane Descemeta , which  reduces the risk of transplantation  rejection and possible complications).

It  is necessary to continue wearing hard contact lenses after transplantation.

Cornea transplantation

Refractive disorder that is caused by  cornea cone  is very high. It generates the usual rise of myopia and very high  astigmatism, which can be corrected  by hard contact lenses.
