Frequently Asked Question About Lasik

Efficacy

Q What results can I expect from the LASIK procedure?
A LASIK improves the uncorrected vision (vision independent of corrective lenses) in most patients who undergo the procedure. Over 90% of patients with low - to - moderate myopia will achieve 20/20 vision. However, there are no guarantees that you will have a perfect vision, and patients with high myopia (more than -6D) and high hyperopia (more than +4D) should expect differently. People who are most satisfied with the results of laser correction possess realistic expectations of what their vision will be like after surgery.

Q Will my vision be as crisp after the LASIK procedure?
A Patients need to understand that the 20/20 vision after LASIK might be different from the 20/20 vision with corrective lenses. Some people describe the images they see postoperatively as not being as “crisp” as those seen through glasses or contact lenses.

Q How long will it take for me to be able to see well, and how long will it take for me to have my best vision?
A Fast visual recovery characterizes this operation. Most patients achieve good vision on the day of surgery and find that their eyes feel fairly normal within a day. However, vision can continue to improve, and the best vision can take as long as 2 to 3 months. If necessary, adjustments to the surgery called enhancements can be performed. Patients who undergo hyperopic LASIK often need to wait longer to be able to see clearly. Typically, they are unable to see with intense clarity for one or 2 weeks, with best vision being achieved several months postoperatively.

Q Are the results of LASIK surgery permanent?
A LASIK is a surgical procedure that permanently removes the corneal tissue to reshape the eye in order to improve refraction. The physical results are permanent. However, one should be aware of the fact that the condition of the eyes can change with time and that LASIK does not affect a number of visual conditions associated with age. For example, LASIK does not prevent presbyopia or affect this condition once it does occur.

Q If I undergo the LASIK procedure and my vision changes later in life, can it be repeated?
A Depending on the cause, retreatment may be a viable solution to vision changes later in life, and other treatment options do exist. You would need to consult your ophthalmologist to determine the cause of the change and determine which option is best for you.
