Frequently Asked Questions about
Laser Vision Correction…
Which procedure is better for my particular needs, LASIK, EPI-LASIK, or PRK?
All three procedures are very effective in correcting nearsightedness, farsightedness, and astigmatism. LASIK has become the procedure of choice for most patients due to its quicker recovery time and reduced risk of discomfort after the procedure. There are several factors however that should be considered prior to making any decisions as to which procedure best fits your needs. At Iowa EyeCare/ TLC, we are experts in all three procedures, and will help you choose the safest, best procedure for your correction.
Which device will be utilized to create the flap of corneal tissue in the LASIK procedure?
At Iowa EyeCare/TLC Laser Center, we most commonly use a device called an Intralase to create the corneal flap. This allows us painless, blade-free, predictable, safe results.
Is laser vision correction permanent?
Yes, laser vision correction results in a permanent change to the shape of the cornea. Laser vision correction will not prevent age related conditions such as presbyopia (the need for reading glasses) or cataracts. These conditions would still be treated in their normal manner.
What kind of laser will be utilized during my procedure?
We use the newest generation VISX Star S4 ActiveTrak Excimer laser system with Iris Registration. These lasers utilize the latest active eye-tracking system and variable spot scanning technology, in addition to numerous other advancements, which enable the surgeon to deliver the best outcome possible. The eye tracker compensates for small eye movements by guiding the laser beam to keep it centered precisely over the treatment area, allowing for an improved level of precision, comfort, and safety. Variable spot scanning technology allows for treatment of patients with a larger pupil size.
What are the long-term effects of laser vision correction?
Laser vision correction has been performed since 1987. The FDA has approved the use of the Excimer laser and recognized laser vision correction as being safe and effective for the treatment of nearsightedness, farsightedness, and astigmatism in eligible patients. In the United States alone, over two million procedures have been performed. Most experts worldwide are confident that they will discover no long-term problems with laser vision correction. The procedure has become the most commonly performed refractive surgery in the world.
When can I return to work and normal activities?
Most patients notice dramatic improvement within the first few days following the procedure and are able to drive a car and return to work within one to three days. Most LASIK patients see quite well the next day. The speed of visual recovery ultimately depends on personal healing patterns. After laser vision correction the restriction on activities are minimal and these will be covered in detail prior to the procedure.
What if I currently wear contact lenses?
Prior to laser vision correction it is important that the curvature of the corneas return to their natural shape. The only way to ensure this is for contact lens use to be discontinued. For most patients who wear soft contact lenses the cornea will return to its natural shape within 3 to 7 days prior to the procedure. Thirty days without contact lenses is generally required to reach corneal stability for patients who wear rigid or gas permeable lenses.
What can I expect my vision to be after laser vision correction?
The results of laser vision correction have been overwhelmingly successful in eliminating or reducing the dependence on glasses or contact lenses. In a recent study, 98% of patients treated for nearsightedness and/or astigmatism achieved 20/40 vision after one or more treatments. This means they can drive legally, play sports, and join the police or fire departments without depending on corrective eyewear. Ultimately, how well a person sees and how quickly their vision improves depends on the degree of their prescription and their particular healing pattern. As with any surgical procedure, results cannot be guaranteed. During the initial consultation we will discuss the range of probable outcomes based on your prescription.
Is laser vision correction painful?
There is little or no discomfort during the procedure. Eye drops are used to numb the eyes. No needles or injections are required. After LASIK, postoperative discomfort is minimal. It is common to have some eye irritation the first few hours. With PRK the irritation may last for several days following the procedure.
What if I move my eye during my procedure?
We utilize the most technologically advanced lasers that offer eye-tracking capabilities to continually reposition the laser beam during your procedure. The laser detects and then compensates for small movements by guiding the beam to keep it precisely centered over the treatment area.
Are both eyes treated the same day?
Most patients who undergo laser vision correction have the procedure on both eyes the same day; however, the procedure can be performed unilaterally as well.
What are the risks of laser vision correction?
Long-term sight-threatening complications from PRK and LASIK are very uncommon. The chance of having a serious vision threatening complication is much less than 1%, although no surgical procedure is without risks. Understanding potential risks allows you to make an informed decision before undergoing laser vision correction. Our office will discuss potential risks in greater detail and answer any questions you may have during your screening.
How do I determine if I am a candidate for laser vision correction?
Schedule a complimentary laser vision correction screening with our office. This appointment will take approximately 30 minutes. During the consultation we will determine candidacy and which procedure would offer the greatest benefit for your particular needs.
How long does it take to perform the procedure?
The actual laser time is typically less than two minutes per eye. A person will be in the laser suite only 15 minutes for the actual procedure. The total time spent in the laser center is generally one to two hours. Most people are on their way 20 to 30 minutes following the procedure.
Can laser vision correction eliminate the need for reading glasses?
Yes and no. The need for reading glasses usually begins at age 40 to 45, and is caused by a loss of elasticity of the natural lens inside the eye. This loss of elasticity results in an inability to focus on small print or objects at near. This condition is called presbyopia. Laser vision correction cannot restore the elasticity to the natural lens inside the eye. There is a technique that is commonly used with contact lenses called monovision in which one eye is fit with a contact lens to see at a distance and the other eye is fit with a contact lens to see at near. This technique can also be used with laser vision correction. One eye would be treated to see at a distance and the other eye would be treated to see at near. Prior to using the laser for this technique it is recommended that contact lenses be tried first. If successful, then the same technique could be applied with the laser. It has been our experience that monovision is helpful for near tasks such as reading a watch, menu, or price tags, but not for reading fine print or prolonged close work. It is important to understand that even with monovision almost everyone will still need reading glasses at some point. For people with active lifestyles who play golf, tennis, or drive a great deal at night, monovision is not recommended. It is very important for people who are nearsighted and who are over the age of 40 to understand that prior to laser vision correction it is possible to remove their glasses and see objects at near without corrective eyewear. After laser vision correction reading glasses will become necessary in order to focus on near objects.
Does insurance cover laser vision correction?
Some insurance companies have started covering the procedure, but generally laser vision correction is considered elective and is not offered by many health insurance plans. Our staff will be happy to call your insurance carrier to determine if laser vision correction is an included benefit.
Is there financing available?
Yes, our TLC Center provides monthly payment plans and competitive pricing that makes laser vision correction affordable.
Is laser vision correction eligible through my cafeteria or flex spending plan?
Yes! Using your cafeteria or flex spending plan is an excellent way to pay for laser vision correction.
