What is Laser Eye Surgery?

lasik patpitchayaNot everyone loves wearing glasses, especially when they think they have to because of the need for vision correction. Glasses often do not fit correctly. Sometimes they can get lost or broken. But there is a solution for many people. Laser eye surgery, performed by Dr. Beth Friedland – Park Ophthalmology, can correct a variety of vision problems and make glasses a memory. Many Triangle residents, especially those in our area of Raleigh and Durham, have worn glasses or contacts for many years.  Finding the idea of being free of those glasses is very appealing. Patients who have the procedure done might even achieve vision better than 20/20. There is however, a lot to know about LASIK (laser-assisted in-situ keratomileusis) before making a decision. Here is a short course in laser eye surgery from the Triangle’s Eye Specialist.

LASIK is the most common type of refractive surgery, or surgery that changes the shape of the cornea. The surgery can correct:

  • Nearsightedness — Seeing objects clearly at close range with issues involving distance vision.
  • Farsightedness — Near vision is blurry; more clarity with distance.
  • Astigmatism —  Disruption of focus for near and distance vision.
  • Presbyopia — Age-related eye change that results in the gradual loss of the ability to actively change focus on nearby objects.

It is important to note that at Park Ophthalmology, we recommend trying glasses or contacts for most vision correction before trying surgery. But LASIK can be a great benefit for a lot of people.

However, every benefit has some risk and with LASIK surgery those risks can include:

  • Under correction: This sometimes occurs in individuals who are nearsighted. The surgery may not give perfect 20/20 vision, which means the possibility of corrective lenses or additional surgery.
  • Over correction: If the laser removes too much tissue from your eye, the result is an over correction, which can be somewhat challenging to repair.
  • Astigmatism: This occurs when the eye tissue is removed unevenly and the situation can require additional surgery.
  • Glare, halos and double vision: Any of these problems may occur. Some can be treated with eye drops, but others might require surgery.
  • Dry eyes: Some people may notice a temporary decrease in tear production after LASIK, resulting in dry eyes. Eye drops usually will help this issue during the first few months, but you may need another procedure if the problem is considered severe.

Please note that some patients are not good candidates for this procedure. As with any surgery, it’s important to talk to Dr. Beth at Park Ophthalmology about the pros and cons. Make sure to mention any health conditions, and be prepared to talk to her about any questions or concerns.
