Omar E. Awad, MD:
If you have an abnormal corneal shape, or if your prescription is out of the treatable range, you may not be a candidate.
Omar E. Awad, MD:
We also like to see that a prospective candidate has realistic expectations -- the procedure may seem like MAGIC but it's really just a very sophisticated surgical procedure!
LeeKirksey:
I'm confused about the terminology of the different vision corrective procedures. How do they differ from lasik?
Omar E. Awad, MD:
I'm glad you asked this question - I could talk for half a day about this!
Omar E. Awad, MD:
LASIK is really the most commonly used name for the laser vision correction procedure, but there are a few variations.
Med Help:
Welcome Dr. Kirksey, MedHelp's resident expert on Peripheral Arterial Disease.
Omar E. Awad, MD:
All the laser vision correction procedures use a laser - called an excimer laser - to alter the shape of the cornea (the front part of the eye that you look through).
Omar E. Awad, MD:
LASIK usually refers to the procedure whereby we create a flap in the front of the cornea, lift it up, apply the laser treatment to the "bed," then replace the flap.
Omar E. Awad, MD:
PRK was around even before LASIK. It stands for Photorefractive Keratectomy.  Instead of making a flap, we simply remove the surface "skin" or epithelium, apply the laser directly to the surface, then let it grow back
Omar E. Awad, MD:
There are variations of PRK that some call LASEK with an "E" .  With LASEK - the surface skin is removed temporarily then replaced after the laser is applied.  But that surface skin still has to grow back anyways - just like PRK.  Epi-LASIK is another name for a procedure like LASEK.  Very confusing.
jadec:
I am shortsighted and have recently been diagnosed with dry eyes.  I have had the same prescription for about 5 years now.  Am I a good candidate?
Omar E. Awad, MD:
You should have the dry eye evaluated and treated first before having surgery.  The fact that your prescription is stable is a good sign.  If you dry eye condition is well controlled, you may be a great candidate.  Visit your local LASIK center to find out!
carl377:
Hi-How does wavefront LASIK compare to conventional LASIK?
Omar E. Awad, MD:
The difference is in how the laser is programmed - otherwise they may be exactly the same.  With wavefront LASIK - the laser is programmed using your wavefront refraction, which is a complex formula determined by the aberrometer.  With conventional LASIK, the laser is programmed with your prescription that the doctor measures in the office.
Omar E. Awad, MD:
Your glasses or contacts correct what is called the "lower-order aberrations."  This is what is corrected with conventional.  The wavefront LASIK also measures and treats the higher-order aberrations, kind of like the subtleties of the vision.
Omar E. Awad, MD:
That said, both methods give excellent visual results.  We will measure the higher-order abberations at your pre-operative examination.  If you have a certain level of these types of aberrations, you may do better with wavefront.  Some people have few high-order aberrations, and they typically see great even with conventional LASIK.
AJeffery:
I have herad that the precedure just takes a few seconds for each eye. Is that true?
Omar E. Awad, MD:
Especially with the newest laser platforms that we have at LasikPlus, the laser portion of the procedure often takes only a few seconds!
Omar E. Awad, MD:
There are other portions of the procedure as well, such as creating, lifting, and repositioning the flap.  Altogether, it often takes only a few minutes per eye!  Truly amazing!
latenight:
What are the most recent developments in Lasik? Are there any new enhancements on the way that are worth waiting for?
Omar E. Awad, MD:
The newest improvement in the LASIK procedure is the "all-laser LASIK."  
Omar E. Awad, MD:
The all-laser method has been in development for several years, but it has reached the point where it is clearly safer and a better choice compared to cutting a flap with a conventional microkeratome (blade).
Omar E. Awad, MD:
Different manufacturers are always improving their products from time to time.  At LasikPlus, we have upgraded all our laser very recently to the latest and best models.  
Omar E. Awad, MD:
Now "older" lasers can still work, but the safety, effectiveness, and reliability of the newer models is unparalleled.  
Omar E. Awad, MD:
One of the exciting improvements that we are all "waiting for" is the development of treatments for presbyopia - which is basically difficulty seeing up close after age 45 or so.  Presbyopia treatments are under development but unfortunately are not going to prime time for a while.
lupa:
Are the chances of getting 20/20 good for someone presbyoptic and with hyperopia?
Omar E. Awad, MD:
Yes.  Depends on your level of hyperopia.  If you have a lower level of hyperopia, treating it with LASIK may improve both your distance vision and your near vision!  You will need a full eye exam to know for sure though.
mlb1234:
What is the cost of custom vs. standard lasik? Does the all-laser method cost more?
Omar E. Awad, MD:
Cost is sometimes the first question that people have!
Omar E. Awad, MD:
Custom does cost more than standard LASIK.  We actually have to pay the laser manufacturer every time we use the laser, and a custom card costs more than a standard card.
Omar E. Awad, MD:
Also, there is more staff time that goes into preparing a custom treatment.
Omar E. Awad, MD:
Similarly, the all-laser method can make the cost a little higher, as there is a fee paid to the manufacturer for using that laser as well.  But they are YOUR EYES - they're worth it!
