Influence of Ocular Rigidity and Ocular Biomechanics on the Pathogenesis of Age-Related Presbyopia

This chapter discusses ocular rigidity and ocular biomechanical dysfunction as they relate to the age-related pathogenesis of presbyopia. The major factors associated with presbyopia as they relate to ocular rigidity and ocular biomechanical dysfunction are highlighted. Furthermore, specific reference is made to modifying the biomechanical properties and structural stiffness of the scleral outer coat utilizing laser scleral therapies. Recent literature has illuminated that the loss of accommodative ability in presbyopes has many contributing lenticular, as well as extralenticular and physiological factors which are affected by increasing age.
