20/20 Vision With Laser Eye Surgery Is Reality!

1Hours in front of computer or books, poor heredity in regards to eyesight often impair vision and make us dependant on glasses or contact lenses which means either to put up with being “foureyes” or prepare to have plenty of patience when fiddling with contact lenses. Yet, there’s another alternative. Focusing potency of the eye can be improved with a laser eye surgery. That may first sound like a challenge, especially if you have watched the part of “Final Destination” with the related episode, however, laser vision correction has its indisputable and so tempting benefits. Learning more about the advantages, risks and myths, created around the procedure, will help you to decide for or against the surgery.

Modern medicine offers 2 major methods of laser eyesight correction – PRK и LASIK. The first is a contact procedure, the other is a non-contact one.

PRK or LASIK?

Both surgeries treat nearsightedness, farsightedness, and astigmatism, providing excellent visual outcomes for distance vision practically in all patients. The main difference between the 2 treatments is in the corneal area, where the surgery is performed: PRK is done directly on the corneal surface, while LASIK operates with the underlying corneal tissue (beneath a very thin flap in the cornea.) These different methods determine the term of the healing period: with LASIK it’s much faster (within 2-3 hours) against 3-7 days for good vision of distant objects and up to 3  weeks for the close ones with PRK. Why do some people still opt for PRK? Primarily, for its safety. During PRK corneal tissue is left intact that’s why it has fewer risks, being free of any flap-related complications which aren’t frequent yet still occur with LASIK.

The Mechanism of LASIK Eye Surgery

The whole surgery, performed under local anesthesia, takes about 10 minutes – 5 minutes for each eye.

The goal of the surgery is to reshape the underlying corneal tissue in order to correct its ability to focus light onto the retina. For this purpose a thin flap of cornea is cut with a microkeratome or femtosecond laser to get access to the underlying tissue. Then the procedure of reshaping is performed and the cornea flap is placed back.

Laser Eye Surgery: Benefits

  • According to the statistics, about 85-90% of patients don’t need glasses or contact lenses most of the time after the treatment
  • An opportunity to begin to experience better vision than you have ever had
  • The surgery is suitable for most people with vision problems
  • Quick return of the vision
  • Short recovery period
  • Low risks

Different resources in Internet are full of ads for laser eye correction and encouraging positive responses of those, who have undergone the procedure. However, there is also the other side of the medal. Alas, no surgery can be considered entirely risk-free, and vision surgeries aren’t an exception. The first thing that you might not have heard yet is good results of the laser treatment may diminish with time. The cornea doesn’t stay the same over the years. It goes on aging and may change its shape. What are other moments that should be seriously considered?

Laser Eye Surgery: Possible Risks & Complications

  • Worse vision than before the procedure
  • Flap-healing complications (displaced flap, incomplete flap, debris under the flap, infection, etc.)
  • New visual problems (double vision, a glare, halos, etc.)
  • Dry eyes

In spite of numerous pros and cons, laser eye surgery has become a mainstream treatment for impaired vision. According to the American Academy of Ophthalmology, over 700,000 LASIK procedures are performed annually. Well, ending up with 20/20 vision after the surgery is a worthy opportunity to consider, isn’t it?
