Theoretically and technically Laser eye surgery improves the vision of the eyes, instead of getting worse. Usually, there would be no negative effects or side effects experienced after the surgery.
The overall success of the surgery is dependent on several factors. The first factor is the precession and accuracy of the surgical procedure is conducted, which again depends on the experience of the Lasik surgeon and standards followed during the procedure, reliable infrastructure. And the secondary factor is how well the eyes are protected against any odds or disturbances post surgery. Though there are many other factors that influence the success of the surgery and so the correction of the vision, the above two specified factors play major roles.
In case the above two factors got to influence negatively, like if the surgery is not successful or done with the industry standards or if no enough protection or care is taken post surgery, the following negative effects may be experienced by the patient.
- In any possible case, where changes are occurred in the lens, internal to the eye after the Lasik surgery, any of the conditions like farsightedness, nearsightedness and/or astigmatism will possibly be returned after the surgery.
- The possible side effects are…
- Difficulty to drive during nights
- Dry eyes
- Glare
- Fluctuating vision
- Halos seen around images
Even the patient experiences any one or more than one symptoms after the surgery and recovery period, there is nothing to worry, because there are also some corrective procedures possible. If the patient experiences any farsightedness, nearsightedness or astigmatism, and feels bothersome, it is possible to restore better and clear vision with the Lasik enhancement, which is a follow-up procedure.
Rate of Failure or Side Effects
Most of the patients, who have gone through the Lasik eye surgery find almost no complaints with the vision. The success rate of the Lasik procedure is more than 96% for this 25 year old technology. The rate of success is further increased with the enhancement procedure. The further changes of the vision and eyesight changing with the age can be even corrected by far after Lasik. There is hardly any requirement of the contact lens or eyeglasses after the Lasik surgery.
Considering the statistics, the need for Lasik enhancement is close to 6%, when considering 10 years of duration after the surgery. The cost of the enhancement surgery is minimum or zero immediately after the Lasik surgery.
Having considering all these facts, it is easy to analyse that the Lasik procedure is almost completely safe, when performed with the standards of the industry and post operative care is good enough.
