Scleral approaches to presbyopia moving from niche to mainstream
Among the many options for presbyopia, scleral approaches stand out for their unique attempt to tackle the roots of the problem, restoring physiological function rather than aiming for optical compensation. They had a slow takeoff and limited acceptance, but step by step, through a long path of research and technological upgrades, they continue to move forward. According to several surgeons, they might be the ideal solution for plano or near-plano presbyopia, when the lens is still clear. They are minimally invasive procedures that preserve the visual axis, and patients’ visual experiences can be outstandingly good, even beyond what measurements say.

DYNAMIC RANGE OF FOCUS (DRoF), or the total range of clear vision in a natural system, is an important biomechanical function of the accommodative apparatus responsible for adjusting the crystalline lens from both far to near (accommodation) and near to far (disaccommodation). DRoF is defined by true accommodation, pseudoaccommodation, and pupillary diaphragmatic changes, which work together …

FOR MOST OF HISTORY, PRESBYOPIA has been defined as a “normal” refractive error caused by age, with discussion limited to the loss of near vision beginning in our 40s. Because we have had no effective therapeutic interventions available, presbyopia has been accepted as a natural part of life and treated primarily by changing power at either …
