Cirurgia

Keratoconus is a hereditary and progressive manifestation of the cornea that presents an irregularity of its surface which, instead of being spherical, becomes a protruding deformation similar to a “cone”.

The consequence is that it affects vision and cannot be corrected with glasses.

The so-called classic treatments involved the use of rigid or semi-rigid contact lenses and, in extreme cases, corneal transplantation.

Today, new treatment methods consist of intracorneal ring implant surgery followed by cross- linking and photorefractive keratotomy.

Less advanced cases do not require the aforementioned surgical intervention and Cross-Linking treatment alone can guarantee complete stabilisation of the process in more than 90% of cases.

For this reason, it should be carried out as soon as the diagnosis is made, even if there are not yet any symptoms.

Finally, after Cross-Linking, it is possible to use the Excimer laser to improve vision and “regularise” the cornea a little more. This often makes it possible to use soft contact lenses. As in normal eyes, refractive surgery to implant phakic intraocular lenses improves quality of life and in most cases avoids the final solution of corneal transplantation.The so-called classic treatments involved the use of rigid or semi-rigid contact lenses and, in extreme cases, corneal transplantation.
