senso semi sceleral
The Senso Semi Scleral lenses offer a good alternative for corneal lenses in irregular
corneas and sensitive eyes or both. The weight of the lens is divided between cornea and
sclera, resulting in crisp and clear vision and good wearing comfort.
All lenses are laser marked with Procornea logo and unique batch number. This means
guaranteed quality.
Features:
• Solution for irregular corneas and sensitive eyes
• Crisp and clear vision
•Optimal wearing comfort
Fitting advice:
Base curve radius = K (mean) + 0.05 mm.
Choose a lens from the trial set. Evaluate central (corneal) fit with fluoresce in, evaluate peripheral
(scleral) fit. A good fit shows a slight movement with the push up test, and shows tear exchange
underneath the lens upon each blink.
The ideal fit can be reached by adjusting the BCR in combination with the peri factor of the
periphery.
