Laser Vision Correction Checklist
What other options are available for correcting refractive errors? (Back to Top)
By far, the most common method is eyeglasses. Another popular option is contact lenses; either soft or rigid gas permeable. Common problems with contact lenses include irritation, daily inconvenience, and ongoing cost of lens replacement and contact lens solutions.
Is laser eye surgery painful? (Back to Top)
The LASIK procedure is associated with a sensation of pressure during certain steps of the surgery, but the patient rarely describes it as painful. There may be mild to moderate discomfort following LASIK, but most patients find that their eyes are quite comfortable following this procedure. The advanced surface ablation (ASA) procedure usually causes some discomfort. However, the discomfort only occurs during the first one to three days following the surgery. A soft contact lens is placed on the eye at the end of surgery, and this acts like a bandage to help minimize discomfort. The amount of discomfort is quite variable among patients. Most individuals have minimal discomfort, while some have mild to moderate discomfort.
How do I decide between undergoing ASA and LASIK? (Back to Top)
The results of both procedures are comparable for low to moderate amounts of near-sightedness, far-sightedness and astigmatism. The advantages of LASIK are that vision often recovers within just one or two days and there is usually only minimal or no discomfort after the procedure. LASIK does introduce the small additional risk of the use of microkeratome (flap-maker), although problems with this fortunately are very rare. The advantage of ASA is that there is no flap, so no chance of flap complications, but the recovery of vision takes a little longer. We will be glad to discuss these options with you and make our recommendation, according to your particular situation.
What if I move my eye during the laser treatment? (Back to Top)
While the treatment is being performed, you are required to look at a red blinking light located on the inside of the laser. It is important that you look steadily at the light throughout the operation, since this keeps the eye centered for the laser. However, if you temporarily look away or lose the ability to look at the fixation light, do not be concerned. The laser uses the most advanced 3D active tracking technology and will stop the treatment if the eye is not perfectly centered and resumes treatment once your eyes are re-centered.
Can I have both eyes treated at the same time? (Back to Top)
We have successfully performed bilateral sequential LASIK and advanced surface ablation (ASA) procedures in thousands of patients. Most patients prefer this to waiting between eyes. In the field of laser vision correction, most doctors usually perform surgery on both eyes on the same day.
Is Laser Vision Correction permanent? (Back to Top)
Laser Vision correction has been performed since 1995. Presently, the procedure appears to be permanent with regard to distance vision correction. However, the main change that occurs during aging is associated with reading vision. This will be discussed during the consultation process if it applies to you and your specific refractive error and age.
How long does the procedure take? (Back to Top)
The average length of time at the surgery center is about 1½ hours. The procedure takes approximately 10 minutes. The actual exposure to the laser is less than a minute per eye.
When can I resume my normal activities following laser surgery? (Back to Top)
Following LASIK, one can usually drive within a day or two and return to full activity by 2 or 3 days. Following Advanced Surface Ablation (ASA), most individuals find that they can return to work and drive in 4-5 days. Full activity can begin within 4-5 days, but patients are asked not to go swimming or use hot tubs for three weeks following either procedure.
How often do I need to be seen after the procedure? (Back to Top)
Typically, patients will need to be seen the day after the procedure followed by visits at one week, and another visit at four to eight weeks. We highly recommend that patients be available for follow-up during the first 7-10 days after surgery.
When does my vision recover following laser refractive surgery? (Back to Top)
Following LASIK, vision is quite satisfactory in one or two days following the operation. Vision then improves over the next week (although in some cases vision may further improve over the next few months), assuming that no additional correction is needed. Following ASA, vision is typically blurry for the first 5-7 days. Some patients experience excellent vision as early as one week, whereas for others, the full recovery may take several weeks. In some cases with high corrections, vision can take a few months to improve but throughout this time you are fully functional.
Can laser refractive surgery cause me to lose vision? (Back to Top)
As with any operation, Advanced Surface Ablation and LASIK are not risk-free. In the U.S. studies of Laser vision correction using the AMO excimer laser, serious complications or problems occurred in less than 1% of the patients. These complications included loss of vision even with glasses; over and under correction and visually significant corneal haze.
What is Visx CustomVue technology? (Back to Top)
Visx CustomVue is an individualized laser vision correction procedure that is wavescan driven. This advanced wavefront technology enables us to measure and correct imperfections that are unique to each individual’s vision that could not have been measured before with standard equipment. CustomVue helps us to create a tailor-made correction for your eyes.
Will LASIK or ASA eliminate my need for reading glasses? (Back to Top)
Neither procedure changes the gradual loss of focusing power that occurs as we get older. If one’s near-sightedness in both eyes is nearly or fully corrected with LASIK or ASA, then reading glasses will be required at around age 40-45.
One option that is successful in some patients is called monovision. In this approach, one eye is deliberately left with a modest amount of near-sightedness, permitting this eye to serve as the reading eye. In many patients, this can reduce or eliminate the need for reading glasses until the mid-50s.
The compromise, of course, is that the eye that is left with some near-sightedness does not see as well at distance. This could slightly decrease depth perception and is not recommended for individuals with special needs, such as pilots.
What if any side effects will I notice after LASIK Laser Vision Correction? (Back to Top)
Most everyone will experience glare and halos in the immediate postoperative period. Your eyes will also feel dry after the procedure, but this can be relieved by the use of non-preserved artificial tears. It is rare that these side effects persist longer than 2-6 weeks. Some patients may not achieve their expected uncorrected visual outcome. If this is related to an under-correction or over-correction, you may be a candidate for an enhancement of the original surgical procedure.
