What is Myopia?
Myopia is nearsightedness or difficulty seeing objects in the distance. It can also cause squinting, eyestrain, headaches and eye fatigue. Myopia currently affects approximately 1/3 of adults currently in the United States. Myopia usually starts in childhood and worsens over time.
The issue lies within the shape of the eyeball in relation to the curvature of the cornea and the lens of the eye.
What causes Myopia?
No one is entirely sure. Studies show that heredity does play a part in whether or not someone develops myopia. If both parents wear glasses, there is a higher likelihood that their child will also need them. There are also some studies that suggest that reading may play a role in myopia development.
Our goal at ECS is to treat the myopic condition and to slow its progression.
There are several treatment options for myopia. Traditional glasses and contact lenses offer clear vision but do not slow the myopia. LASIK surgery can work for adults but is not recommended for children. Pharmaceutical intervention through medical eye drops can help control the progression of myopia for a while, but have negative side effects. Orthokeratology is the wearing of specially designed gas permeable contact lenses that reshape your cornea while you sleep. This can help slow the progression of myopia, but does not offer a permanent solution.
In recent research, the use of contact lenses, in which a patient’s prescription is in the middle of the contact lens surrounded by plus power, has shown to reduce myopia progression by 40-50%. It is suggested that when using these contact lenses to slow the progression of myopia that the patient utilize this modality until their early twenties.The center optics of the contact lens will correct for the myopia and deliver focused light rays on to the macula at the back of the eye. The peripheral retina is what studies have shown to be the driving force for the elongation of the eye leading to an increase in myopia. With distance only correction, the macula will have a focused image delivered to it, but the rays being delivered to the peripheral retina will not be focused on the retina, rather behind it. By placing the plus power around the myopia prescription, the light rays in the peripheral retina are focused on or in front of the retina helping to reduce the tendency for the elongation of the eye.
