BASCOM PALMER CONTACT LENS SOFTWARE
Several companies provide hardware and software that has the capability to create an initial scleral lens based on the profilometry of the patient’s sclera. A patient fitted with a scleral lens after ocular surface reconstruction. With modern day material having a Dk of 200 and new modes of acquiring the corneoscleral profile to assist in complex fits with challenging anatomic limitations, the variety of patients that can be fit successfully has dramatically increased (Main Figure and Figure 2).įigure 2. This is likely due to lens stability and improved centration. The combination of these details can help mask corneal irregularities and improve overall quality of vision as well as provide relief for patients with severe ocular surface disease (ie, Stevens-Johnson syndrome, ocular graft-versus-host disease, ocular cicatricial pemphigoid) and allow that disease to heal.īecause scleral lenses rest on the sclera and conjunctiva, which are substantially less innervated than the cornea, they are significantly more comfortable than corneal RGP lenses and, in some instances, can also deliver improved vision.
1 Scleral lenses are rigid gas permeable (RGP) contact lenses that are shaped to the patient’s sclera, vault over the cornea, and deliver continuous hydration through a liquid bandage located between the cornea and the posterior surface of the lens. Scleral contact lenses are increasing in popularity, as they play a crucial role in the management of several corneal and ocular surface diseases. A scleral lens with significant toric haptics.
