    How To Read The Charts

    Farsightedness The Options chart is read in diopters, the unit of optical measurement.

  • Look at your prescription.
  • If a minus sign appears before the first number (sometimes noted as "sphere") then you are nearsighted, or myopic. Follow the number down the nearsighted chart to determine the refractive surgery options for your level of correction.
  • If a plus sign appears before the first sphere number then you are farsighted, or hyperopic. Follow the number down the farsighted side of the chart to find your refractive options. Astigmatism

    The second number on a glasses prescription card shows your level of astigmatism. It's sometimes labeled "cyl" or "cylinder".

  • Follow this number to determine which correction options are available to you.
  • The third number in a prescription is the axis of the astigmatism. It is an important number for us to utilize during your treatment, but it is not a number that will help you use the above chart s to assess which procedures are good options for your correction.

    What Vision Correction Option is the best for you?

    Use the above tables as a guideline. Please remember that this is a guide to give you an idea of the range your correction falls within and the options available. The best review of your currently-available options occurs during your consultation in our office.


  • Premium Lens Implants

    The LASIK procedure is the right answer for most patients who are considering refractive surgery to improve their vision. However, in patients with higher degrees of nearsightedness or farsightedness, the cornea may be too thin to allow full refractive correction.

    In these cases, surgical implants may be the best alternative. These special devices are placed in the eyes to improve their focusing ability.
