Abstract Details

Purpose:

PresbyMAX is a non invasive corneal procedure treating presbyopic patients. PresbyMax provides a combination of micro-monovision and an increase of depth of focus by changing the sperical aberrations for the near and/or distant eye. Using two different types of PresbyMax, customizing the amount of spherical aberrations, the degree of monovision depending on patient age and expectations it is possible to provide a high degree of natural vision. We evaluate the efficacy and safety of PresbyMax in eyes myopic and hyperopic eyes.

Setting:

Excimer Laser Schwind Amaris 1050 RS, Femtosecond laser Ziemer Z6, PresbyMax hybrid/monocular profile, EyeLaser Vienna Clinic

Methods:

PresbyMAX is a corneal procedure treating presbyopic patients. It provides a combination of micro-monovision and an increase of depth of focus by changing the sperical aberrations for the near and/or distant eye. Using two different types of PresbyMax, customizing the amount of spherical aberrations, the degree of monovision depending on patient age and expectations it is possible to provide a high degree of natural vision. Myopic, emmetropic and emmetropic patients were included in the study. We treated with hybrid and monocular profile. Their pre-operative-, surgical data and refractive outcome at six months were analyzed. Safety of the procedure was evaluated.

Results:

The surgery significantly reduced the spectacle dependance for near and distant vision (sphere, and cylinder) at 6 months of follow-up. At 6 months 85% eyes achieved binocular UDVA 20/40 or better, 99 % eyes achieved binocular UNVA 20/40. 7 eyes lost 1 line. Due to high degree of customization, changing the degree of monovision and spherical aberration, adjusting to individual needs it is difficult to quantify the visual outcome. The retreatment rate was 19,5%. A tendency of undercorrection in myopic patients and overcorrection in hyperopic eyes was found. Manipulating the size of optical zones influences the visual outcome.

Conclusions:

PresbyMax is a minimal invasive, safe procedure with very fast recovery using femto-lasik technique. The possibility of customization helps achieving a hight degree of satisfaction, however retreatment options and presbyopia progression needs to be discussed.
