3R Punens Orthokeratology Lens: A New Design for myopia Control
What is the 3R Punens Lens?
The 3R Punens is the newest orthokeratology lens developed by Jaume Pauné Fabré, an optometrist and contact lens designer specializing in myopia and myopia control. this innovative lens features a single geometry with three tear tanks, designed to optimize hydrodynamic forces and improve lens centering – a critical factor for successful treatment.

How Does the 3R Punens Lens Work?
Orthokeratology (Ortho-K) involves wearing specially designed contact lenses overnight to temporarily reshape the cornea. This reshaping corrects refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism, providing clear vision during the day without glasses or contact lenses. The 3R Punens lens aims to enhance the effectiveness of this process through its unique tear tank design.
The three tear tanks are strategically positioned to maintain optimal hydration and facilitate natural tear exchange under the lens. This improved fluid dynamics contributes to better centering and reduced corneal stress, perhaps leading to more consistent and predictable results.
Indications and Parameters
the 3R Punens lens is indicated for a broad range of refractive errors and levels of myopic progression.It offers three defecting choices - standard, advanced, and reinforced – to tailor treatment to individual patient needs.
| Condition | Sphere (Plan) | Cylinder (Plan) |
|---|---|---|
| Myopic Evolution | Variable (Standard,Advanced,Reinforced) | N/A |
| Myopia with Astigmatism | Up to -7.00 D | Up to -5.00 D (regardless of sphere) |
| Hyperopia with Astigmatism | Up to +4.00 D | Up to -4.00 D (regardless of sphere) |
Renewal Frequency: Annual.
What are the Benefits of Improved Centering?
Lens centering is paramount in Ortho-K success. A well-centered lens applies consistent pressure across the cornea, ensuring uniform reshaping. Poor centering can lead to:
- Reduced visual acuity
- Increased risk of corneal complications
- Unpredictable treatment outcomes
The 3R Punens lens’s design specifically addresses centering, aiming to minimize these risks and maximize treatment efficacy.
Who is Affected by Myopia and Orthokeratology?
Myopia is a growing global health concern, especially among children and young adults. Increasing screen time and reduced outdoor activity are believed to contribute to its rising prevalence. Orthokeratology offers a non-surgical choice to conventional vision correction methods, appealing to individuals who prefer not to wear glasses or contact lenses during the day.
The 3R Punens lens, with its focus on improved centering and hydrodynamic performance, might potentially be particularly beneficial for patients with complex corneal shapes or those who have experienced challenges with other Ortho-K designs.
