The lenses are designed to bridge over the entire distorted cornea, resting on the white part of the eye (sclera), providing an artificial smooth corneal surface to restore vision and protecting the already unhealthy cornea from further damage. However, the disadvantage of scleral lens is that it is harder to insert and remove because the diameter of the lens is large.
With modern technology 3D corneoscleral topography and anterior Ocular Coherence Tomography (OCT), optimum fitting can be achieved. Scleral lens can provide an improved vision for many advanced cases. Moreover, because a scleral lens must be fitted with saline solution or artificial tears filled between the back of the scleral lens and the cornea, it makes it useful for patients with severe Dry Eye Syndrome (DES) or Ocular Surface Disease (OSD).
A regular review is essential to monitor your eye health and to assess the fitting of the lenses. If you are not happy with the vision outcome from your soft contacts lenses or eye glasses, it would be worth coming to our clinic to have an eye health workup. All our patients would have corneal topography checked at their initial consultation.
