Keratoconus Symptoms
Keratoconus Surgery
-
Rigid Gas Permeable Contact Lenses
Early Keratoconus can be managed by giving rigid gas permeable contact lens to the patient, which corrects the irregularity of the cornea and provide better quality of vision. In advanced keratoconus, these lenses may not fit the eye optimally and become difficult to wear.
-
Rose K Contact Lens/Scleral Boston Contact Lens
Theses are special custom made contact lenses which give better fit and superior vision quality. These are ordered after taking various measurements of cornea.
-
C3R (Corneal Collagen Cross Linking wit Riboflavin)
This is the only treatment to stop the progression of Keratoconus. It is based on collagen cross- linking with ultra-violet A (UVA, 365 nm) and Riboflavin (Vitamin B2, a photo sensitizing agent). This increase in corneal strength has shown to arrest the progression of Keratoconus in almost all cases and it can reverse the Keratoconus changes by 20 to 30 percent.
-
Cornea Transplant
This is a surgical treatment, which is reserved for advance cases of Keratoconus, where the vision cannot be improved with glasses or contact lenses. Here the central portion of the cornea is removed and replaced with a donor cornea of similar size. Since there is high possibility of complications and graft rejection, this keratoconus surgery is done for selected cases.
-
Intacs
These are acrylic rings inserted in the corneal stroma to decrease corneal irregularity in cases of Keratoconus. They can improve uncorrected vision without contact lenses. These can also be combined with C3R.
