Enhancing the quality of vision through custom contact lenses
WaveTouch custom contact lenses are designed using measurements of both lower and higher order aberrations. A patented manufacturing process takes an individual’s wavefront profile (including total aberrations of the cornea) as measured by the iTrace Visual Function Analyzer, and ablates it onto the contact lens.
Wavefront aberrations are classified as lower or higher order. Lower order aberrations include defocus (myopia and hyperopia), astigmatism and tilt. Higher order aberrations like coma, trefoil or spherical aberrations cause symptoms such as blurring, glare and halo around lights, and poorer vision at night and in low light conditions. Standard prescription eyewear or contact lenses cannot compensate for higher order aberrations.
WaveTouch custom contact lenses address both lower and higher order aberrations by not only improving standard myopic and astigmatic vision, but also including higher order aberrations to reduce blurring, and glare and halo thereby improving day and night vision.
Custom contact lenses can also especially benefit difficult to fit patients such as:
- Keratoconus patients
- Post cross-linking patients
- Patients with irregular refractions
- Decentered ablations due to refractive surgery
Wavefront custom contact lenses provide superior quality of vision compared to standard contact lenses. Patients with RMS values greater than 0.3 um can benefit greatly from custom contact lenses.
