Semi Scleral GP Lens SphereThe ICD™ 16.5

With a close match of tangent lens shape to tangent eye surface, the ICD™16.5design provides an exceptional first fit success rate. Practitioners simply choose from

a 14-lens fitting set and assess three principle fitting zones: apical clearance, limbalclearance and scleral landing fit from corneal topography which is ideal forassessment of corneal pathologies across the widest area of the cornea. ICD™16.5can just as easily be fitted from corneal topography, such as the Medmont E300,which offers the widest corneal measurement available.

ICD™ 16.5 was developed by a prestigious group of clinicians with Paragonmaterials technology and represents a powerful combination when industry andclinicians come together. It is manufactured under license at Soflex’ s lens facility inIsrael.

ICD™ 16.5 addresses the urgent need to fit corneas with conditions ranging from:

Bulging corneal transplants Corneal transplants Keratoconus Kerato-globus Pellucid marginal degeneration Post refractive surgery Normal shaped corneas .

The simplified fitting approach that ICD™ 16.5 employs, combines Paragon HDS ® 100 material, which will benefit novice to expert scleral lens fitters and patients alike.

Fitting procedure:1. Determine sagittal depth at a chord diameter of 15mm, add 400 microns for

apical clearance or use the 'quick start guide' for empirical fitting. Evaluate theCentral Clearance Zone (CCZ) to verify there is 300-400 microns of centralclearance.

2. If significant edge lift is present, select a lens with increased sagittal depth.Upon achieving acceptable CCA and SLZ it is recommended you allow lensto "settle" on the eye for a minimum of 60 minutes.

3. Evaluate each zone for proper fit: Central Clearance Zone - CCZ

Diagnostic lens should completely vault central cornea. Limbal Clearance Zone - LCZ

Diagnostic lens should completely vault limbus.Order modified LCZ if necessary: A "+" step change in LCZ creates a larger sagital depth A "-" step change, in LCZ creates less sagital depth

Each step expect 25 microns more / less central clearance. Scleral Landing Zone - SLZDiagnostic lens should land with full weight on sclera.The ideal peripheral alignment/bearing of the lens can also be noted bythe absence of fluorescein near the edge. View the SLZ for excessiveedge lift or excessive tightening (blanching).Order a modified SLZ if necessary: A "+" step change in the SLZ increases the sagital depth, (tightens the SLZ) A "-" step change in the SLZ decreases the sagital depth, (loosens the SLZ)

The ICD 16.5 (Paragon) lens has a planar limbal clearance zone that is intended tovault the limbus and can be adjusted by tangent angle.

Lens Care:Care of these lenses is identical to care of gas permeable lenses (GPL).Before handling contact lenses, wash your hands and dry them thoroughly.It is advisable to have the lenses cleaned at a laboratory every three months.

1. Wet the lens with hydrating solution a few minutes before removal from theeye.

2. Remove the lens and place it on the palm of your hand.3. Put a few drops of cleaner under and in the concave part of the lens.4. Rub both sides of the lens with the index finger, for approx. 20 – 30 secs.5. Rinse the lens thoroughly in saline solution.6. Immerse the lens in conditioner in a clean case.7. Repeat the process with the second lens.
