We do it all!

Our goal is to give you your very best vision for all of your specific needs. 

 

Myopia (Nearsightedness)

Myopia is the most common refractive error. This is them number one reason patients are prescribed glasses and contact lenses.  The vast majority of LASIK patients are myopic and we are able to treat very high myopia with this procedure. There are over 70 million residents living in North America (almost 25%) that are afflicted with myopia (nearsightedness). As the term “nearsighted” suggests, myopic patients can see near objects more clearly than distant objects due to this refractive error. The higher the myopia you have the more blurry distant objects will appear to you. Highly myopic prescriptions require lenses that traditionally had very thick edges and could be very heavy and difficult to wear. We can prescribe newer state-of-the-art lens materials to reduce the thickness, weight and give you amazing vision.

Myopia is caused by the eye being too long in relation to the curvature of your cornea. This causes the light rays that enter the eye to focus in front of the retina, instead of directly on the fovea, producing a blurred image.  Negative powered ad concave shaped lenses correct this defocus and refract the light to the correct focal lenght.

The severity for myopia can vary. Most patients are mildly or moderately nearsighted.  But there are cases of severe and extreme myopia, which can be quite debilitating with out corrective lenses or surgery.

Categories of Myopia:

  • Mild Myopia is less than -3.00 diopters
  • Moderate Myopia is between -3.00 to -6.00 diopters
  • Severe Myopia is between -6.00 to -9.00 diopters
  • Extreme Myopia is over -9.00 diopters

Hyperopia/Far-Sightedness

Hyperopia (farsightedness) is the exact opposite of myopia. It occurs when an eye's length is shorter in relation to the curvature of  the cornea. A patient with low hyperopia may see distant objects seen more clearer than nearer objects, but in higher hyperopia this can be misleading as all distances can be quite blurry.

The cause of the blurred vision is that light rays entering the eye are not focused well enough to come into focus on the retina. They are focused behind the retina and produce a blurred image. The term "farsighted" really is not the most accurate description.  Patients suffering with uncorrected hyperopia can use their eye muscles to focus the image forward toward the retina, allowing them to see a bit clearer. To maintain this clear these patients must constantly engage the focusing muscles of the eye. This often causes significant eye strain and frontal headaches. Mildly hyperopic patients often see rather well until the onset of presbyopia. This is when the internal lens of the eye loses its focusing ability and flexibility. This occurs between 40-45 years of age.  Most patients can't overcome the detrimental effects of higher hyperopia and need correction in the form of eyeglasses or contact lenses to give clear comfortable vision at both distance and near.

Categories of Hyperopia:

  • Mild Hyperopia is less than +2.00 diopters
  • Moderate Hyperopia is between +2.00 to +4.00 diopters
  • Severe Hyperopia is between +4.00 to +6.00 diopters 
  • Extreme Hyperopia is over +6.00 diopters

Astigmatism

Astigmatism occurs when your cornea is shaped like an egg. With astigmatism, more than one focal point within the eye distorts what you see. As a result, you experience a tilting of images due to the unequal bending of light rays entering your eyes.

Many patients with myopia and hyperopia have some degree of astigmatism, or an oval shape, to their cornea. People with high degrees of astigmatism have blurred vision for both near and distant objects. We can correct astigmatism with glasses, contacts and even LASIK surgery.

Below are the categories of severity for astigmatism:

  • Mild Astigmatism < 1.00 diopters
  • Moderate Astigmatism 1.00 to 2.00 diopters
  • Severe Astigmatism 2.00 to 3.00 diopters
  • Extreme Astigmatism > 3.00 diopters

Presbyopia

Presbyopia is a normal part of aging that becomes more apparent as people approach their 40s and 50s. As the human body ages, the lens inside the eye grows like rings on a tree.  It loses its elasticity, and therefore its ability to easily change focus, making it more difficult to read smaller print.

Nearsighted people who become presbyopic may require bifocals or progressive lenses starting in their forties, and those who never needed glasses before may need reading glasses.  There are many corrective options including multifocal and monovision contact lenses that can reduce your need for reading glasses.

Mild myopia counteracts presbyopia, which is why patients who are slightly myopic with presbyopia may still be able to read when they remove their glasses.

Your doctor will recommend an individual course of treatment after a thorough examination. Dr. Stelzer will evaluate and determine the best vision correction options for a patient with your prescription to help you make the most educated decision.
