MLAS Glossary of terms


In astigmatism, the problem is not the length of the eye, but the fact that the cornea is not spherical in shape but is rather shaped more like a football than a basketball. The result of astigmatism is that objects are not focused into a single image and vision is distorted or blurry. Often, people who have nearsightedness also suffer from astigmatism. LASIK can treat up to 6D of astigmatism.

Farsightedness or Hyperopia

In farsightedness or hyperopia, light entering the eye focuses images at a point behind the retina. Farsightedness is frequently caused by an eye shape that is abnormally short or by an excessively flat cornea. The result of farsightedness is that objects near to the viewer appear blurry, while objects in the distance may be seen in focus.

LASIK can treat up to 6D of hyperopia, although we recommend to people in their 20s and 30s with an unstable prescription to wait on the surgery. Your vision may change as you age, or if your prescription has recently changed, we advise that you wait until your vision is stable.

Nearsightedness or Myopia

In nearsightedness or myopia, light entering the eye does not focus on the retina as it should but instead focuses images at a point in front of the retina. Nearsightedness is frequently caused either by an eye shape that is abnormally long or by an excessively steep curvature of the cornea. The result of nearsightedness is that distant objects appear blurry, while objects near to the viewer can be seen in focus.

LASIK can treat up to 12D of myopia with the technology offered at Millennium Laser Eye Center. If you are still in your 20s or 30s and do not have a stable prescription, we might recommend waiting to undergo surgery until your vision stabilizes, as younger people with nearsightedness can still experience vision changes due to aging. 


Presbyopia, or the inability to see close-up objects, usually becomes apparent to most people in their early forties. This condition occurs normally with age and results from a change within the eye in which the internal lens loses its ability to focus on close-up objects.
