LASIK surgery is a form of laser surgery performed to correct vision. Kenneth Goins, MD, an ophthalmologist at University of Iowa Hospitals and Clinics Department of Ophthalmology and Visual Sciences, talks about LASIK surgery, how it works, and who can benefit from LASIK surgery.
How is LASIK eye surgery different from other surgery to improve vision?
LASIK is the acronym for Laser-Assisted In Situ Keratomileusis, which is one of the most advanced treatments for the correction of nearsightedness, farsightedness, and astigmatism. Specifically LASIK reshapes the cornea so that light rays are able to focus directly on the retina, thereby improving vision without the need for contact lenses or glasses.
Who is a good candidate for LASIK eye surgery?
Good candidates for LASIK surgery are usually those that are 21 years of age or older, they have good eye health, excellent physical health, and last but not least, realistic expectations. For example, LASIK usually does not improve the vision in an eye that does not see well with glasses or contact lenses.
Can LASIK surgery be done on both eyes on the same day?
Yes, LASIK is commonly done on both eyes on the same day to help reduce the recovery time needed to resume normal routine daily activities.
How long does it take a patient to recognize the difference in their vision after a LASIK procedure?
There may be significant eye pain, burning, and tearing immediately after LASIK, which usually lasts approximately two to six hours. But after this subsides, most patients notice a vast improvement in vision, and after 12-24 hours, it is not uncommon for a patient to have 20-20 uncorrected vision.
What are the benefits of LASIK surgery?
The major benefit of LASIK is that it reduces one's dependence on glasses and contact lenses to see clearly.
Are there risks involved in LASIK surgery?
As in any surgery, there are risks associated with LASIK, such as dry eye, infection, and glare and halos. But the occurrence of these problems is low and the severity may be markedly reduced when postoperative follow-up examinations are kept.
When you say post-op follow-up, is it multiple procedures? Is there anything that a patient can do once they leave the doctor's office? How involved does that get?
Sometimes patients see so well after LASIK they forget to return for their postoperative examination. I just want to make it clear that most complications can be troubleshooted and managed properly if I can just see the patient early.
Will a LASIK procedure improve eyesight for the rest of a life, or will it need to be repeated as a patient ages?
LASIK usually does not have to be repeated as the patient ages. However, after the age of 40, there's a natural loss of accommodation or the ability to focus at near. In this situation, LASIK may be used to enhance spectacle and contact lens independence.
If someone is thinking about having a LASIK procedure done, what should they look for in a medical specialist?
Patients should consider a LASIK surgeon who has many years of experience; uses state-of-the-art technology, such as femtosecond and wavefront guided excimer laser treatments; and performs pre- and post-surgical evaluation of the patient.
If someone is interested in learning more about LASIK surgery at UI Hospitals and Clinics, can they refer themselves or do they need a referral from a physician?
No direct referral from a physician is all that is needed. And I'd like to note that we're hosting a free informational seminar on Tuesday, July 24, from noon to 1 p.m. Those interested in attending that seminar, schedule an evaluation, or just want more information, can call 319-353-7625 or e-mail at LASIK@uiowa.edu . |
