Bzovey B. Perspective on: Multifocal contacts benefit young adults, those with presbyopia Primary Care Optometry News 2022;April 18 [ Show Abstract ]

MCLs are used to manage myopia, based on the theories of peripheral retinal defocus and accommodative lag, by removing the signals that cause the eye to elongate.

It has been thought that center-distance designs are best for maintaining distance visual acuity (VA) and are the better choice for myopia control. This article describes that center-near MCLs can be another option that maintains distance VA.

The researchers discovered that center-near MCLs can degrade distance VA, with the higher add having a more significant degradation effect than a standard monofocal lens. They showed that young adults with accommodation (24- to 38-year-olds) overall had better VA than presbyopes with MCLs; the young adult’s distance and near VAs were maintained around 6/6. Pupil sizes showed a minimal effect on performance on either group, indicating preservation of good VA and functionality in center-near MCLs.

Accommodative lag is thought to be one of the theories of axial elongation in myopia. This report discusses how center-near MCLs allow a more accurate accommodative response, reducing accommodative lag. While additional research is required to investigate the efficacy differences of center-near vs. center-distance for myopia control, the presence of the near addition in MCLs will produce a sufficiently strong inhibitory signal to slow down myopia progression.

Whether setting up a new practice, upgrading current equipment or choosing new equipment, the available choices can be overwhelming. There are many decisions to be made, including those based on cost, space and functionality. And with substantial growth opportunities within primary care practice, from services including specialty contact lens practice, dry eye and myopia management, making the right decision is important.
Practitioners looking for innovative instruments to support their myopia control practice should consider the clinical information required to manage their patients, including refractive error, keratometry and axial length. In addition, attention should be given to the footprint that any new equipment takes up.
Practitioners wishing to best utilise valuable practice space with a multi-function instrument can now consider the Myopia Master from Oculus (figures 1 and 2) as a standalone option for their myopia management practice. This sleek, all-in-one unit will check many boxes on the list of clinical measurement and functionality requirements to support this fast-moving area of clinical practice.
