Control Nearsightedness

Do You or Your Child Have Frequent Prescription Changes?

                

Do you or your child need stronger glasses every year? If so, we now have ways to stop or reduce progression. Stronger prescriptions are not only more costly but they signify a disease process that puts the eye at greater risk for the sight threatening conditions.

Dr. Marran is leading expert in understanding risk factors and treatment of myopia. Here are the clinically proven methods she uses to control or stop myopia development.


  • Myopia Control Soft Contact Lenses

Provide both clear vision and protection against myopia progression. Dr. Marran O.D. Ph.D. wrote the FDA protocol for Misight Contact Lenses by Cooper Vision. While not currently available in the U.S., Dr Marran O.D. Ph.D. uses a similar design that has been proven to be highly effective in preventing myopia progression in her patients. A daily disposable lens, it is both convenient and safe for all ages. It is also a less expensive alternative to Corneal Reshaping technology (CRT) or Overnight Gas Permeable Lenses (Ortho K) and has a better safety profile.

Specialized contact lens slows myopia progression in 3-year study

Three-year data from CooperVision suggests that a new contact lens therapy substantially slows myopia progression and eye elongation in children as measured by refractive error and axial length at the 3-year mark.
CooperVision senior manager of clinical research Paul Chamberlain, BSc(Hons), presented the study results at the British Contact Lens Association Clinical Conference in Liverpool, England.


According to a press release from the company, the clinical trial assessed a specially designed, dual-focus myopia control 1-day soft contact lens to reduce the rate of progression of juvenile-onset myopia in a prospective, multicenter, randomized multiyear study with 144 myopic children, 8 to 12 years old, from Singapore, Canada, England and Portugal. The lens contained alternating visual correction and treatment zones.
At 3 years, the use of the dual-focus contact lens was effective in slowing myopia progression 59% as measured by mean cycloplegic spherical equivalent and 52% as measured by mean axial elongation of the eye when compared to the children in the control group wearing a single vision contact lens.
“Early intervention by parents, in partnership with eye care professionals, is essential to the near- and long-term health and well-being of their children,” according to Arthur Back, BOptom, PhD, FAAO, chief technology officer, CooperVision, in the release. “The CooperVision MiSight dual-focus 1-day lens used in this study provides a new, effective and repeatable approach.”
Parents of the study participants also had a positive response, noting their children could mostly manage their lens wear independently. Nine out of 10 parents rated their children “extremely happy” with the overall experience of wearing contact lenses.
In a statement to Primary Care Optometry News, CooperVision did not speculate on an approval timeline, but the company said it remains committed to working with the FDA. – by Abigail Sutton

Center distance multifocal contacts may slow, halt myopia

Practitioners should consider using multifocal contact lens designs that slow the progression of myopia in children, according to researchers.
The retrospective case series included 32 patients between 6 and 19 years old who were at least -0.50 D with current corrections. The subjects were fit with an extended depth of focus (center distance) multifocal soft contact lens, NaturalVue Multifocal 1 Day Contact Lenses by Visioneering Technologies Inc.


At the initial visit, 44% of patients wore spectacles, 37.5% wore spherical soft contact lenses, 15.6% wore a different soft multifocal contact lens, and 3% wore orthokeratology lenses.
Researchers found reductions in the annualized rate of myopic progression from -0.85 D per year to -0.04 D per year in the right eye and -0.90 D per year to -0.03 D per year in the left eye.
Approximately 98.4% of the children showed reduction of annualized myopic progression, and 91% showed a decrease of 70% or greater, researchers wrote. More than 80% showed complete halting of myopic progression, including 6.25% demonstrating myopic regression.
Researchers believe that the significant reduction of myopic progression was due to the higher amount of plus in the periphery associated with the extended depth of focus optics in the lens design.
“Given the high risk of ocular complications with increased levels of myopia, practitioners should consider using multifocal contact lens designs that slow the progression of myopia in children as a proactive part of their clinical practice,” Cooper and colleagues concluded. – by Abigail Sutton

  • Vision Therapy to treat the cause
In her clinical research, Dr. Marran O.D. Ph.D. was able to show that extended near visual tasks can make it difficult to the eyes to be able to relax for distance vision in susceptible individuals. These individuals show certain clinical signs when tested in the exam room. In her workup for patients with progressive myopia, Dr Marran O.D. Ph.D. determines what is contributing to that progression and designs a therapeutic program to address these deficiencies.
  • Progressive Addition Lenses
Patients with certain clinical signs can reduce their myopia progression from a correction that gives clear distant vision as well as some help at near. Dr. Marran uses a specially designed lens which gives a wide field of view, no peripheral distortion and requires little to no adaptation to the PAL.
  • Low Dose Atropine Eye Drops
An off label but highly effective intervention is the use of 0.01% Atropine. Occasionally patients will experience mild side effects of dry eye, light sensitivity or near blur but these can mediated by specialized glasses the darken outdoors (Transitions) and the use of specialized glasses (See PAL Lenses above).

NEW TECHNOLOGY: VTI MULTIFOCAL LENS

This has been proven to impact three visual risk factors for myopia!

  1. Lag of accommodation  
  2. Amplitude of accommodation
  3. Peripheral hyperopia

Pilot data shows that the lenses have the highest efficacy in suppression of myopic development. The data also indicates excellent vision at all distances and that most children feel no discomfort while wearing them. Call our office if these lenses are right for you or your child!

"Nearsightedness or myopia is a symptom before it is a condition. We make it into a condition by treating the symptom and not the cause. By treating the symptom with glasses, we lock the person into nearsightedness for a lifetime. In fact, while glasses provide clear vision and are often necessary, they actually contribute to the eyes becoming more nearsighted (myopia progression).

Dr. Marran O.D. Ph.D. hopes that these intervention programs will become the Standard of Care for patients with Myopia. Until then, she is passionate about converting other Eye Care Providers to make this a part of their routine treatment through Continuing Education lectures at the Academy of Optometry and other optometric meetings.
