Myopia Control Therapies

By Thomas P. Finley, OD

Myopia, or nearsightedness, is the condition that makes it difficult to see clearly far away. Myopia is the most common refractive error of the eye.

A recent study estimated that about 1.4 billion people, or 23% of the global population was nearsighted in 2000. This number is expected to soar to 4.8 billion, or 49.8% of the world’s population by 2050. These projected increases in myopia are driven largely by lifestyle changes involving more near-work activities at earlier ages on computers and digital electronic devices causing eye strain and fatigue, and less time spent outdoors. Heredity and genetics also play a role. Unfortunately, it’s not uncommon for children to become more myopic than both parents. Many other factors also affect one’s affliction toward myopia.

Myopia usually begins developing at an early age, especially considering the early use of digital devices. Myopia generally increases every year until late teens and early twenties when it begins to stabilize. Everyone is unique.

Traditional treatment for myopia includes eyeglasses, contact lenses, and when the eyes are stable and not changing, laser vision correction. This article will focus on methods to help control myopia.

Orthokeratology, Ortho-K,
Corneal Refractive Therapy, CRT

These are all terms for similar treatment modalities. They involve being fit with a reverse geometry specialty rigid gas permeable contact lens. The patient wears the lenses while sleeping. The lenses gently and painlessly reshape the cornea (front surface) of the eye, allowing the patient to see well all day long without eyeglasses or contact lenses.

Studies have demonstrated this is one of the more effective therapies available to help control myopia and slow down or halt its progression.

Multifocal Contact Lenses

Multifocal contact lenses have traditionally been reserved for patients age 40 and older who need help seeing both far away and up close. With improving contact lens technologies, these lenses may be an effective tool for children unable to wear Ortho-K lenses. Special multifocal contact lenses may be beneficial in myopia control.

Anti-Focusing Eye Drops

Atropine eye drops can have a beneficial effect on myopia control, but is not recommended to use year after year. The drops have a negative effect on a person’s focusing ability on objects up close.

Bifocal and Multifocal Eyeglasses

Studies have shown wearing bifocal or progressive eyeglasses can slow myopia progression compared to single vision lenses.

Eye Exercises

Eye exercises can improve visual efficiency and visual skills, but contrary to advertising claims seen on the internet, do not correct myopia. It was thought under-correcting myopia could have a beneficial effect, but studies indicate this is worse than fully correcting myopia, as well as causing increased eye strain from squinting.

The best way to control myopia is to detect it early by having a comprehensive eye examination. Children should receive a thorough comprehensive eye examination before they begin preschool. Discuss all treatment options with your doctor and make certain your doctor is experienced in myopia control therapies.
