Scleral contact lenses and Kerasoft IC lenses are fitted in patients with corneal irregularities such as keratoconus, post-refractive surgery ectasia, post-corneal transplants and complicated astigmatism prescription.
Scleral contact lenses can be as big as soft contact lenses and sometimes even bigger depending on the condition that has to be managed. It is truly an important tool for optometrists to use especially on keratoconus patients as corneal transplant can be delayed because these lenses can provide good to great vision even in those patients with severe or advanced conditions. Scleral lenses are also being used to manage patients with dry eyes. Because the bowl can be filled with liquid, it protects the cornea and moisturises it. Scleral lenses are truly life changers for patients, from not being able to see well enough to have a job to being able to find a job and excel on it.
Kerasoft IC lenses on the other hand are customized soft contact lenses indicated for patients with mild to moderate conditions stated above. It brings convenience to patients who desire to have a more straightforward contact lens regimen.
Both these lenses are very comfortable compared to regular rigid gas permeable lenses that treat the same conditions.
Some of these conditions can bring about astigmatism that can be addressed by using specialty contact lenses such as RGP, scleral lenses and customized soft contact lenses (KerasoftIC). While some may benefit from the tear reservoir found in scleral contact lens wear.
