A. Laser vision correction is a type of refractive surgery using an excimer laser. This surgical procedure may reduce or eliminate your dependency on glasses and contacts.
A. The two excimer laser surgical procedures available are Laser Assisted Intrastromal Keratomileusis (LASIK) or iLASIK a blade-free approach to laser vision correction. A third procedure is Photorefractive Keratectomy (PRK) also known as Advanced Surface Ablation (ASA). At the Spokane Eye Clinic we use iLASIK and Advanced Surface Ablation/PRK.
A. iLASIK and Advanced Surface Ablation/PRK use the precision of the excimer laser to reshape the surface of the eye (known as the cornea). Because the excimer laser is a “cool” laser, it will not burn or cut tissue. Additionally, the laser energy is applied to only a very small part of the surface of the cornea.
A. In the iLASIK procedure, an intralase laser is used to create a thin cap of corneal tissue. This cap is gently folded back from the surface of the cornea so that the excimer laser can be used to reshape the cornea for vision correction. The corneal cap is then returned to its original position, adhering quickly without stitches. In the Advanced Surface Ablation/PRK procedure, the excimer laser is applied directly to the corneal surface for vision correction. To enhance healing following Advanced Surface Ablation/PRK, a soft contact lens is worn for three up to six days and then removed.
A. If your eye is healthy and your prescription has been stable plus your general health is good, the only age requirement for refractive surgery is that you need to be at least 21 years old.
A. To find out more about vision correction options and which one may be right for you, you can schedule a no-cost personal consultation at Spokane Eye Clinic. If you are interested in proceeding with refractive surgery following your personal consultation, a comprehensive pre-surgical eye examination will be scheduled with your doctor.
A. The actual procedure takes from 5 to 15 minutes. The total time for your surgical visit will range from one to two hours.
A. Advanced Surface Ablation/PRK and iLASIK procedures are generally considered to be “painless procedures.” Your eye is anesthetized with eye drops prior to and during the procedure. Following the procedure and after the anesthetic wears off, most patients experience little to no discomfort. Some patients do, however, experience light sensitivity or watering of the eyes from one to three days following the procedure. You will have eye drops to take following the procedure to help relieve discomfort should you have any.
A. After the procedure, you will need to have someone drive you home and you will need to plan on seeing your doctor during the first few days following the procedure. During this time, you will be taking eye drops which will comfort your eye and help reduce the risk of infection. If your eye is healing as expected, routine follow-up visits will be scheduled for one month, three months, six months, and one year post-op.
A. As with any surgical procedure, there exists the potential for side effects or complications. The degree and frequency of occurrence will vary from patient to patient. Early and temporary side effects include discomfort, light sensitivity, and vision fluctuation during the healing process. Infection risk is very low and, if present, is usually treated with antibiotic drops. Corneal haze may occur after surgery, but usually resolves with treatment and time. With laser correction, there is also a chance of over or under correction. Over and under corrections usually do not affect the overall vision results. High amounts of under correction or over correction are generally retreated with an enhancement procedure. Low amounts of under correction are corrected by wearing glasses as needed for activities such as night driving. Rarely (<2% of cases), best corrected visual acuity may be less than before surgery. Dry eyes which is generally treatable with artificial tears and resolves within 1 - 3 months, but may be permanent. As part of your pre-surgical examination, you will have the opportunity to learn more about and discuss the potential risks with your doctor.
A. Between one month and one year after surgery, refractive stability is usually achieved. With about fifteen years of follow-up worldwide, refractive errors following laser surgery seem to be quite stable.
A. Minor changes or fluctuations may occur over time and will vary from patient to patient. There will, however, be changes to vision unrelated to refractive surgery brought about by certain conditions of the eye related to aging, such as presbyopia. Presbyopia, the loss of flexibility and focusing power of the lens of the eye affecting near vision, usually develops between the ages of 40 and 50 and will occur whether or not you have had refractive surgery.
Refractive surgery improves nearsightedness, but does not improve presbyopia. Many patients are candidates for monovision, however, which is a technique to counteract presbyopia. With monovision, one eye is corrected for distance vision and the other eye is corrected for near vision. Also, we know that some people become less nearsighted in their 50s and 60s. This may happen to some laser patients, although it has not yet been demonstrated. Your doctor can discuss the monovision option with you during your pre-surgical examination.
A. Yes. Nearsightedness (myopia), farsightedness (hyperopia), and most types of astigmatism can be treated with refractive surgery. Your doctor can discuss your particular situation during the pre-surgical examination.
A. Results will vary depending upon your particular situation and healing tendencies. Outcome data does show that approximately 96% of patients achieve 20/40 vision or better - sharp enough to pass a driver's license eye test without corrective lenses. Current Eye Clinic results show that 70 percent of eyes achieve the equivalent of 20/20 vision with traditional LASIK, and 90% with custom iLASIK. Current retreatment rates are less than 4 percent.
A. Healing times vary from patient to patient with the average patient's eye feeling normal within 48-72 hours after Advanced Surface Ablation/PRK and 24-48 hours after iLASIK.
A. Most patients having iLASIK or Advanced Surface Ablation/PRK surgery elect to have both eyes done at the same surgery. While there may be some additional risk to bilateral surgery, the risk is statistically unidentifiable and there is a considerable convenience benefit to bilateral surgery. Occasionally, patients may elect to have one eye done at a time and sometimes your doctor will recommend having only one eye done.
A. If you war contacts, you can continue wearing the contact in the uncorrected eye until your doctor instructs you to discontinue its wear in preparation for surgery on the second eye. If you wear glasses, you can have one lens without any correction put into your glasses over the eye that has been treated until the second eye is treated.
A. The amount of time required for recovery will vary from patient to patient. Factors affecting how soon you will be able to return to work include your healing time, your occupational demands, and the particular procedure which you have done. On average, most iLASIK patients return to work one to three days after the procedure and Advanced Surface Ablation/PRK patients normally return to work in 1 week.
A. Once your eye is healed as determined by your doctor during your follow-up visits, there are generally no limitations to the activities which you may perform. Your doctor will be able to discuss your particular situation with you. As always, it is recommended that you wear proper eye protection when engaging in any activity which can cause injury to the eye.
A. Yes. Since your vision will have a tendency to fluctuate during pregnancy and while nursing, it is recommended that female patients who are pregnant or are nursing delay having refractive surgery until their vision stabilizes afterwards.
Q. Will my family eye doctor/optometrist be able to perform the before and after eye care associated with refractive surgery?
A. If you regularly see one of our doctors who does not perform refractive surgery or an eye doctor who does not practice at Spokane Eye Clinic, he or she can perform the necessary pre- and post-operative eye care as long as he or she is certified in refractive surgery co-management.
A. Laser Assisted Intrastromal Keratomileusis (iLASIK) and Photorefractive Keratectomy (Advanced Surface Ablation/PRK) are performed at the Spokane Eye Surgery Center located at 427 S. Bernard Street in Spokane, Washington by local surgeons.
A. Currently, iLASIK is $2,400 per eye and Advanced Surface Ablation/PRK is $1,800 per eye (includes pre and post-op care, surgeons fee, and facility fee). If an enhancement is necessary, the enhancement fee is $250 per eye and will be the responsibility of the patient. If the patient is outside of the 1 year post-operative period they will be responsible for an exam to evaluate enhancement options.
Since refractive surgery is generally considered to be an elective procedure, it is usually not covered under most insurance programs. There are a few progressive companies that may provide coverage. Additionally, many companies have flex plans and payroll deduction policies which may be of benefit to you. We also accept the following major credit cards: Visa, Mastercard, and Discover. We also have financing program available to you for your convenience.
A. Yes, financing is available through Care Credit. Eligible patients at the Eye Clinic may have the option to finance the procedure over 12 months with interest free options.
A. ICR surgery has recently been approved for myopia under 3 diopters with minimal astigmatism. Currently, Eye Clinic physicians are considering and investigating its use. The procedure currently seems to have no cost advantage, applies to a limited number of refractive candidates, and has much less follow-up experience than LASIK or PRK. Its main advantage seems to be its potential reversibility. We will continue to keep you posted about our current opinion regarding ICR surgery.
A. To find out more about vision correction options and which one may be right for you, we welcome you to schedule a no-cost personal consultation at Spokane Eye Clinic.
