OrthoLens is a modern Orthokeratology lens, and thanks to its special geometry it eliminates all or most myopia by reversible modeling of the cornea. The OrthoLens is worn at night while sleeping, allowing the wearer to enjoy clear vision all day without glasses or contact lenses. The correction is 70% from the first night, complete after 3 to 4 nights and stabilizes after 4 weeks.
OrthoLens significantly improves the quality of life of patients and allows myopia control for younger patients without irreversible changes.
The posterior surface of the OrthoLens lens is made up of five zones
Each of these areas is defined with a specific curvature and width calculated for a given cornea
The success of adjustment of OrthoLens lenses depends on the consideration of three essential points
Choice of trial lens
The fit of the OrthoLens does not require a trial lens; the lens is custom-made based on the corneal topography, and specially dedicated software will calculate the parameters of the OrthoLens lens to be fitted.
Send to the laboratory :
- Corneal radii of curvature
- Eccentricity in both meridians
- Corneal diameter
- Pupillary diameter in ambient light
Evaluation of fit:
Use a drop of physiological serum without preservative (or moisturizing eye drops) before inserting the lens, then proceed to evaluate the fit:
- Central zone: centered vertically and horizontally, approximately 3 to 5 mm in diameter
- If the area is not identifiable, the lens is too tight
- If the area is too dark, the lens is too flat
- Center pitting also indicates fit is too flat
- Tear reservoir: 0.5 to 1 mm wide, without air bubbles
- Alignment zone: Aligned with the paracentral cornea 1 to 1.5 mm wide
- Peripheral clearance: from 0.5 to 0.8 mm
