Risks of Lasik Eye Surgery

While modern science and technology has helped many of our medical treatments and procedures to enjoy much improved accuracy and safety levels, there are, unfortunately, still some risks that you will need to consider before you finally commit to a more significant operation or surgery. This is especially true of surgeries that address your vision health. That is why we have put together the following information regarding the risks of lasik eye surgery.

One of the most common risks involved with this particular type of eye surgery is that your vision may actually be over corrected or under corrected. While most procedures produce satisfactory results the first time, some patients have had to return for a second procedure, which is referred to as an enhancement, in order to sharpen the patient’s vision. This situation occurs more often for patients who have a higher degree of prescription for their glasses or contact lenses. In these cases, the patient will have to wait a longer period of time after their initial surgery before they can revisit the eye specialist for a second procedure since their eyes will need more time to heal in between and stabilize. In addition, some of these patients may not even be accepted for a second procedure or enhancement if their cornea is too thin (this could result in a complete tearing of the cornea) or if the cornea is abnormally shaped after the initial treatment and would not be acceptable for yet another reshaping.

In addition, patients suffering from cases such as hyperopia, or farsightedness, are at a greater risk for still needing their glasses or contact lenses after the surgery and may even experience a decrease in vision later down the road. Also, even if your vision is corrected for hyperopia, the lasik procedure may actually cause you to then need glasses or contact lenses for close vision capabilities.

Another risk, although somewhat uncommon, is that your improved results may not be permanent. However, these patients may still be candidates for a future surgery or second enhancement. Some of the more common aberrations include anisometropia (difference in refractive power between the two eyes), aniseikonia (difference in image size between the two eyes), double vision, hazy vision, fluctuating vision during the day and from day to day, increased sensitivity to light, glare, shadows, and seeing halos around lights. However, these conditions have sometimes been known to dissipate over time.
