Myopia Control

Myopia Control

The most common vision issues among our patients here at Super Vision Center is myopia. In fact, myopia, or nearsightedness, is the most common refractive eye issue in the world. If you are suffering from nearsightedness we offer several treatment options for our patients. The International Academy of Orthokeratology and Myopia Control (IAOMC), of which Dr. Berke is a fellow, is an organization dedicated to scientific research and education worldwide. They hold annual conferences with world renowned speakers. Prior to your next appointment with Dr. Berke at Super Vision Center in Santa Ana, check out these questions about myopia.

Myopia Control Q & A

Super Vision Center

What is Myopia and its Dangers?

Myopia is a refractive error in your eyeball.  When you look at distant objects they are not in focus.

Myopia and myopia control have become one of the major health issues on the planet.  Myopia, or Nearsightedness, once considered just an optical or refractive error is now considered as a disease.

In fact, the Centers for Disease Control (CDC) now views progressive myopia as an epidemic disease affecting 1.6 billion children and adults worldwide, with expectations that the number will hit 2.5 billion by 2020.  It has gone up 75% in the U.S. since the 1970’s and at current rates there are 400,000 new myopic cases in America per year!  Increasing Myopia not only causes blurrier and blurrier distance vision but more importantly it can significantly increase the odds of developing sight threatening conditions like retinal holes, tears and detachments, macular degeneration, cataracts and glaucoma. See: D.I. Flitcroft. (2012) The complex interactions of retinal, optical and environmental factors in myopia aetiology. (ABSTRACT) Progress in Retinal and Eye Research VOL 31 (2012) 622-660 doi: 10.1016/j.preteyeres.2012.06.004 For further information see:

Extensive research has shown that orthoK can slow the progression of myopia reducing the risk of retinal detachment, cataract and glaucoma as well as the social issues associated with wearing thick, heavy glasses. Ironically, the image focused by glasses and conventional soft lenses may actually contribute to the axial length growth of the eye, increasing myopia. For more information go to:

What is the Cause of Myopia?

Distance vision is blurry because your eyeball is typically too long in measurement from the front to back and the image falling on the retina is not in focus.  Uncommonly you could have myopia because your eye’s cornea or lens is too curved.  Some people have a combination of these issues that result in their myopia. Other symptoms may include having headaches caused by eye strain as you try to focus on objects in the distance.  Near vision is usually great without correction. The landmark study by Earl L. Smith III, OD, showed that peripheral retinal defocus was the cause of myopia progression and that OrthoK lenses bring the peripheral focus back to the plane of the retina thus breaking the feedback loop that tells the eye to stop elongating and stops the myopia progression. Listen to Dr. Earl Smith, OD, PhD as he explains the relationship between refractive error and eye growth:
