PresbyMAX is a method of presbyopia treatment performed using technologically advanced SCHWIND AMARIS eye laser systems. The treatment is completed in just a few minutes, and the actual laser ablation takes only seconds. The procedure neither touches nor replaces the sensitive lens of the eye. Rather, rapid laser pulses gently model the cornea with high precision.
Several different treatment variants are possible with the PresbyMAX procedure. Your specialist will advise you about the variant which suits you best.
Unlike conventional LASIK treatment, multiple precisely calculated focal points are created in the eye – similar to the principle applied in multifocal contact or intraocular lenses. The cornea is modelled at the centre for near vision and towards the periphery for distant vision. This results in a good depth of field and very high quality vision at all distances. Visual acuity typically improves very rapidly following treatment at a rate roughly comparable to the case of conventional LASIK treatment.

The intermediate zone favours good vision at medium distances, e.g. at a computer workstation. The distant zone provides for good vision at greater distances. The transition zone contributes to the stability of the treatment result.
PresbyMAX + Mosaic PiXL
Mosaic adopts PiXL(Photorefractive Intrastromal Cross-Linking), which is based on the principle of conventional collagen cross-linking(CXL) ,a therapeutic procedure that strengthen the biomechanics of corneas with ectatic disorder. Unlike conventional CXL that uses a broad and diffuse UVA light, PiXL is customized to deliver specific patterns and intensities of UVA light base on an individual’s refractive error and corneal topography. An active eye tracker is utilized during the procedure to ensure pinpoint accuracy in delivering the intended pattern of treatment, potentially improve the visual outcome of other procedures.
Allows patterned, precise, topography-guided accelerated cross-linking with:
- Active eye- tracking
- Integration of corneal topography data
- Custom patterns with digital micro-mirrors
- Significantly higher power and energy
- PiXL and Accelerated Cross-linking procedure
