Laser Eye Surgery Risks and Benefits

Laser eye surgery is performed to improve the ability to see and to correct the shape of the cornea. Let us see the risks and benefits that this surgery comes with, in this article.
Laser eye surgery is performed using a computer controlled laser. It is useful for people with shortness of vision, and astigmatism. More than 80% of the people undergoing the laser surgery are satisfied with the results. However, every patient willing to undergo the surgery should be fully aware of the risks and benefits of laser eye surgery. These have been explained below.

Benefits of Laser Surgery
  • Laser surgery is like a one time investment. Once you recover completely from it, you can save a lot of money on eye examinations, buying contact lenses and eye solutions and drops.
  • You will not be required to wear your spectacles all the time.
  • Maintaining contact lenses is a big issue for many people. You can get permanent relief from all these issues once you perform this surgery.
  • You will be able to do all your day-to-day activities like shaving, playing sports, working on the computer in your office, driving a vehicle, etc., without wearing spectacles.
  • Apart from the eye specialist's fees and medicines, you will also be saving a lot of money on your optician visits.
  • Many people feel more confident and happy without their spectacles.
Risks Involved
  • Many people who undergo the surgery experience dryness in their eyes. This is due to the reduced capacity of the eyes to produce tears due to the damaging of the corneal nerves.
  • The tears produced by the eyes help to keep the eyes moist. This side effect of the laser surgery may or may not be permanent.
  • Due to this dryness in the eyes, the ability of the eyes to see things properly decreases.
  • Laser surgeries in certain people have led to a serious condition known as corneal ectasia. Corneal ectasia is characterized by the presence of a fluid build-up in the eye after laser surgery. If this kind of complications arise, then eye surgeons usually recommend the corneal transplant operation.
  • The possibility of vision loss due to laser surgeries also cannot be ruled out.
  • The issues like blurred vision, possibility of developing double vision are also common side effects of this surgery.
  • Some people face problems seeing clearly or driving at night.
  • Infections are another commonly experienced side effects of this surgery. Patients need to be very careful and take precautionary measures.
  • Some patients complain that their vision before surgery was better than after. This question raises doubts about the effectiveness of the laser surgery.
  • Retinal detachment and cornea problems also follow laser surgery in some cases.
The above mentioned risks are not applicable to each individual. Researchers over the world are studying the risks and benefits of laser eye surgery to discover better and safer options for patients.
