A few years ago, the only alternative that patients with this type of visual problem had was the corneal transplantbut today there are new techniques to avoid it.
He keratoconus It is a progressive deformation of the cornea, in which its shape is distorted, causing it to become conical. It produces blurred and distorted vision, situations that increase over time. It appears in adolescence and can stabilize at age 40.
The patient with keratoconus He can’t get good vision with optical lenses, so they change them very often. Semi-rigid contact lenses can be prescribed, but that does not stop its progression.
These are the new techniques to correct the keratoconusthus avoiding the transplant:
They are plastic segments in the form of semi rings that are located inside the cornea, through a special program made to each patient. Their advantage is that they correct the astigmatism almost entirely since they regulate the corneal shape.
Is a surgery with drop anesthesia. It lasts approximately 10 to 15 minutes, and has a visual recovery of one month.
It is a technique in which riboflavin and vitamin B2 drops are applied to the cornea, which will be stimulated with ultraviolet light for 30 minutes, to gradually strengthen and stabilize the corneal tissue and thus prevent its continuous deformation.
It is indicated for patients in processes of destruction, thinning or deformation of the cornea as in keratoconus. It is usually performed after intracorneal ring surgery.
