Q: How safe is laser eye surgery? A: Similar with other forms of surgery, eye surgery does have potential risks that you should be aware of. The exact success of surgery is impossible, what is done is that an accurate prediction is made based on the large numbers of people who underwent the same procedure in the past. Major complications associated with this type of surgery are very rare.
Q: Is laser eye surgery painful? A: The surgery its self does not cause any pain. What may be felt is a small pressure on the eyeball and surrounding region during the operation. Some degree of discomfort and/ or pain occurs for 2-3 days after laser eye surgery. LASIK eye surgery typically has less pain associated with it, compared with the other types of eye surgery available, e.g. PRK.
Q: Is guaranteed perfect vision from LASIK and PRK generally achievable? A: Not at all. Since each patients eyes react differently to treatment no 100% guarantee of perfect eyesight is available. Past operative achievements are used to generate an estimate of the chances of creating perfect eyesight.
Around 95% of people with low levels of myopia and astigmatism (maximum three diopters) who undergo laser eye surgery tend to achieve near-perfect or perfect vision. Higher levels of astigmatism or myopia still allow the majority of patients to gain near-perfect or perfect vision, although there is a significant chance that contact lenses or glasses may be required from time to time. If so required further surgery can be made to improve the patients clarity of vision.
Q: The corrective surgery is effective for what period of time? A: After your eyes have healed from the operative damage caused the final effect is permanent. In some cases that are extremely rare regression occurs. Further surgery is possible to correct this. The vast majority of people who've undergone corrective eye surgery have eyes that remain in focus. Normal changes in the eyes do occur, as you get older your eyes may become slightly shorter sighted. Patients are only operated on if their focusing error is deemed stable.
Q: Is it possible for both eyes to be surgically corrected in the same day? A: So as to be safe operations on each eye take place two weeks apart. This method allows the vision from the corrected eye to stabilize before the other eye is operated on. Any infections that could, however rare, appear are less likely to spread from the operated-on eye to the healthy eye.
As with any other type of procedure, you should make sure that you are absolutely positive that you want to have lasik laser eye surgery done before going through with it, and that means that you need to weigh all of the advantages and disadvantages, and consult with your physician as well before going through with the procedure.
What are the Advantages of Lasik Laser Eye Surgery?
There are many advantages that can be gained from having the lasik eye surgery done, for example many patients who are considering refractive surgery done are interested in comparing the advantages of lasik eye surgery over the other available types of eye surgery, due to the incredible benefits that are thought of as coming from the lasik laser eye surgery.
As well, with this surgery there is a much faster recovery time, and there will also be a smoother corneal surface and better optical quality even furthermore. There is also a reduced risk of infection with this procedure when compared to that of others, and this is because there is less need for potentially hazardous prophylactic steroids to be used, and in addition, this procedure has a much greater range of vision correction.
The Risks and Complications
The risks and complications of this procedure would basically be considered as being the disadvantages, and in regards to this, as with any surgery, there are certain risks and complications that are present that must be taken fully into consideration.
For instance, there are certain flap complications that could occur, which would include such things as: irregular or incomplete flaps, flaps that are too small or too thin, buttonholes which are small holes or tears in the center of the flap, or free caps which are flaps without a hinge - these are just some examples, as there are more possibilities.
However it should be known that in most cases, flap complications will pose no threat and truly cause no permanent damage or decrease in that of that patient's visual activity. Furthermore, if and when a flap complication does occur, the surgeon will then typically halt the procedure in order to reposition the flap properly.
Overall, if you have weighed all of the advantages and the disadvantages, and still want to go forward, then that decision is obviously up to you; lasik is an elective procedure, meaning that it is not medically necessary to have done.
