SCLERAL LENSES – EUROPA SCLERAL
The EUROPA SCLERAL contact lens is available in a 16mm and 18mm diameter lens. EUROPA SCLERAL lenses rest on the sclera and completely vault the cornea allowing it to hold a fluid reservoir.
The EUROPA SCLERAL is intended to be a 2nd generation JUPITER ESCLERAL™ lens that has been uniquely designed so that it is able to successfully fit a wide variety of corneal and scleral geometries. Multiple fitting sets are not necessary to fit oblate and prolate corneas, as is often the case with other available scleral lens designs.
The EUROPA SCLERAL contact lens is designed to manage mild to severe levels of corneal irregularity and ocular surface disease.
All lenses are plasma treated to ensure surface wetting.
The fitting philosophy of the EUROPA SCLERAL lens is to vault the cornea by 100 to 300 microns with the lens haptic aligning the sclera. A well fit lens should semi-seal to the eye without movement.
fill the lens with non-preserved saline and stain it with a fluorescein strip for diagnostic purposes.
Assess the amount of vault of the diagnostic lens by comparing the thickness of the stained reservoir with the thickness of the lens by turning the slit lamp beam at a 45-degree angle to view the lens/ reservoir/cornea in cross-section (Figure 1). Alternatively, you can use optical coherence tomography (OCT) to measure central corneal clearance. Ideally, the central reservoir thickness should be equal to the lens thickness. Scleral lenses settle by approximately 200 microns which will reduce overall vault to achieve an ideal amount of fluid reservoir.
Then choose another diagnostic lens – either steeper or flatter – until you achieve a vault that matches the lens thickness. It’s more efficient to choose additional diagnostic lenses in 2 to 4 dioptric steps when bracketing the lens fit.
Next, observe the lens fit with a diffuse cobalt light and Wratten filter. The lens should completely clear the cornea, including the limbus (Figure 2).
Use a diffuse white light to observe the haptic portion of the lens, which is resting on the sclera. The weight of the lens should be evenly distributed and should not blanch the blood vessels of the bulbar conjunctiva (Figure 3); however, intermittent areas of blanching are usually acceptable. Contact Visionary Optics’ consultation for assistance if the best diagnostic lens is inadequately fitting the eye.
The final step of the fitting process is to perform a sphere-cylindrical over-refraction to determine power.
