TruForm Siesta 100
Design
- Corneal reshaping lens designed to produce a temporary reduction of myopia
- Four zone reverse geometry design consisting of:
- Central spherical or aspheric zone
- Reverse zone with a steeper curve than the central zone
- Alignment zone that parallels the cornea
- Peripheral curve zone to create edge lift
- Rounded edge terminus extending from anterior to posterior surface to promote comfort
- Approved to be worn overnight with removal during all or part of the following day
Candidates
- Patients who desire to reduce their myopia without surgery
- Refractions with up to 3.00D of myopia and 1.50D of astigmatism
Lens Parameters
- Diameter: 7.0mm to 12.0mm
- Optical zone diameter: 5.0mm to 7.0mm
- Base curves: 6.5mm to 10.5mm
- Reverse zone width: 0.5mm to 2mm
- Reverse curve radius: Up to 2mm steeper than the base curve
- Alignment curve width: 0.5mm to 2.5mm
- Alignment curve radius: 2mm flatter to 2mm steeper than the base curve
- Peripheral curve width: 0.5mm to 1.5mm
- Peripheral curve radius: 2mm to 10mm flatter than the base curve
- Power: -2.00D to +2.00D
- Material: Paragon HDS® 100
Fitting
- Diagnostic lens fitting is not required
- Diagnostic lenses may be helpful in fitting patients whose corneal topography has been distorted by previous contact lens wear
- A basic diagnostic lens set consists of 18 base curves with one optic zone diameter and one overall diameter
