    Ocular Health Implications of the Loss of Dynamic Range of Focus Function in Presbyopia

    Presbyopia is defined as the eye’s loss of ability to focus on objects at near distances, and it is the most common cause of age-related vision impairment. Presbyopia is a significant global health issue that is underdiagnosed. It affects all people in their 40s and older: an estimated 90 million people in the United States …

    Robert Ang Discusses LSM by Ace Vision

    Robert T. Ang, refractive surgeon at the Asian Eye Institute in the Philippines, talks to The Ophthalmologist about the ways Laser Scleral Microporation (LSM) therapy offered by Ace Vision Group comes to benefit him and his patients. He discusses the therapy’s mechanism of action, what the procedure involves, and the unique value offered by LSM. …

    A New Paradigm Shift: Parts 1 and 2 (Pages 25-31)

    DUE TO THE AGING OF THE population, most of our population will spend roughly half of their lives as presby-opes. The etiology of presby-opia has been poorly understood, and treatment options have failed to address the true issues with the disease, creating compro mises in vision that patients are eager to find a solution for, …

    THE ZOOMING EYE LENS: Effects of Age on Dynamic Range of Focus

    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 …

    In-office procedures offer ophthalmic surgeons and patients the greatest flexibility and efficiency of scheduling. Procedures such as YAG capsulotomy, select laser trabeculoplasty, laser pupil iridoplasty, LASIK/PRK/SMILE and minor lid procedures are routinely done within the in-office surgery suite. A large 2016 study demonstrated the safety and outcomes of cataract procedures performed within the surgeon’s office, …

    Dr. Robert Ang in CRST 

    What other future treatments have promise?  Laser scleral microporation is under investigation as a laser treatment for patients with emmetropic presbyopia. Four quadrants of the sclera are treated with an Er:YAG laser to uncrosslink the sclera and rejuvenate the accommodative mechanism (see video demonstration below). Treatment does not appear to affect the visual axis or …

    Treatment landscape for presbyopia evolving toward noninvasive options

    Noninvasive or minimally invasive approaches may be the solution for presbyopia before the onset of age-related cataract and a way to address the increasing need to perform close-range tasks. “The treatments that are currently available have not met our needs,” OSN Cornea/External Disease Board Member Eric D. Donnenfeld, MD, said. “Glasses are an inconvenience. Contact lenses cause …

    Presbyopia treatment options now and on the horizon

    The large number of patients worldwide with presbyopia creates a unique opportunity for eyecare providers to improve patients’ quality of life, according to George Waring IV, MD, FACS. There are more than 2.1 billion presbyopes worldwide. Dr. Waring noted the many implications of this large number, not just from a quality of life standpoint but …

    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 …

    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 …
