PresbyMAX is a new blended-vision approach that improves both near and distance vision for patients in their 40s–50s. The dominant eye is corrected for distance using SMILE or LASIK, while the non-dominant eye undergoes PresbyMAX to create a multifocal corneal profile—enhancing near vision in the central cornea and supporting distance vision in the peripheral cornea.

Abstract
Purpose:
The aim was to analyze the 6-month outcomes of the treatment combination of the monocular bi-aspheric ablation profile (PresbyMAX)
Personalized surgical design aligned with the patient’s desired visual outcome
PresbyMAX® presbyopia correction is performed through a personalized 1:1 surgical design that considers the patient’s occupation and lifestyle, creating comfortable binocular vision at the distances they use most frequently.

Vision Correction Options for Patients in Their 40s-50s
For patients in their 40s–50s planning vision correction after the onset of presbyopia, we determine the most suitable surgical method based on more than 70 pre-operative examination results. This personalized approach allows us to correct both presbyopia and existing refractive errors such as myopia, hyperopia, and astigmatism.
Vision Correction After Presbyopia Has Developed
Benefits of Improved Near Vision
Reduces dependence on reading glasses
Lowers eye strain and focusing effort
With LASIK/SMILE, most patients can resume daily life and return to work the next day
