What Is LASIK Eye Surgery?
LASIK surgery uses a refractive laser to correct vision problems such as astigmatism, hyperopia and myopia. The surgery basically involves reshaping the cornea in order to allow optimal light to refract on the retina to provide clearer vision. To learn more visit Dr. Crews Portland LASIK.
What Are The Risks Of Laser Eye Surgery?
There are certain risks involved with LASIK and there can be some side effects. Dry eyes and disturbances in vision (such as a glare or halo surrounding objects) are common side effects but these normally resolve within a few days to a couple of weeks after the surgery.
There is also a small risk of an under-correction which means not enough tissue was removed from the cornea and therefore the best results would not have been achieved. A follow-up procedure can however correct this problem.
Another risk is where to much tissue is removed called an over-correction. In this case, it may not be possible to correct the error. Astigmatism may result from the uneven removal of tissue and in most cases is correctable. It is however rare that astigmatism, under-correction or over-correction is performed by a skilled and experienced LASIK eye surgeon.
There is also a small risk that the epithelium may grow back abnormally during the healing process. As with any surgery, there is a risk of infection, however, this a relatively small risk due to the fact that a laser is used to perform the procedure.
Changes in vision occur in a small percentage of LASIK eye surgery patients. Total vision loss is even more rare but there is a risk that this can occur.
Laser eye surgery may also be a costly procedure. However, some health insurance policies may cover a portion or total cost of the surgery.
The procedure does not require any general anesthetic which means that patients are awake during the procedure which can be a deterrent to most patients having the procedure performed. Minimal pain can be experienced during the surgery and local anesthetic in the form of eye drops are generally used to numb the area pre-procedure.
Not everyone is a eligible for laser eye surgery and certain health conditions as well as patients over the age of 40 years are not considered to be good candidates for the procedure.
What Are The Benefits Of LASIK Eye Surgery?
Due to the low risks associated with laser surgery to correct vision problems, the procedure is considered safe especially in comparison with other types of eye surgery. The procedure can be completed in around 5 minutes and is therefore very quick and convenient for most patients.
The results from a LASIK procedure are also very quick with most patients reporting improved vision within a few hours to 48 hours after the procedure.
One of the greatest pros of having this procedure performed is that the patient will no longer require glasses or contact lenses.
In most cases, a measurable improvement in vision can be expected and in about 20% to 30% of procedures, full 20/20 vision can be restored.
