Hi Everyone. Welcome to today's health chat on LASIK. The chat will begin at 2 pm Pacific / 5 pm Eastern, but feel free to submit your questions now.
Omar E. Awad, MD:
Hi Everone!  I'm back to talk about one of my favorite subjects - LASIK laser vision correction!
MedHelp:
Welcome again to today's health chat with Dr. Omar Awad.  Thank you for joining us here today.
jledford:
Can you be a good candidate for Lasik if you have chronic dry eyes and possible glaucoma?
Omar E. Awad, MD:
Dry eyes need to be treated aggressively before having LASIK, but you still could be a candidate.  Visit your local lasik center to find out.
Omar E. Awad, MD:
Patients who have glaucoma that is well controlled can have LASIK also.  
LeemaBean:
I have astigmatisms in both eyes. Would that prevent me from having lasik surgery? I have difficulty seeing things up close or from a distance. How can I have lasik when I have both problems with my eyes?
Omar E. Awad, MD:
This is a question I hear frequently, so thank you for posting it.
Omar E. Awad, MD:
Astigmatism can be treated very well with LASIK.
Omar E. Awad, MD:
Astigmatism will cause blurring of vision at both distance and near.  Laser vision correction is probably the best way to correct astigmatism.  And the newest lasers can correct astigmatism very effectively.
Nita59:
I am interested in life without glasses but take so many meds that I don't know if I would be a good candidate.  My meds are Morphine, Dilaudid,Ondansetron, Levothyroxin, Glipizide, Lunesta, Lorazepam, Citalopram.  These do make for dry eyes, at times. Am allergic to all NSAIDS and ASA.  Is there still hope for me?
Omar E. Awad, MD:
You would need a good examination at a reputable LASIK center.  If you have dry eye, this condition should be treated and optimized before having eye surgery.  Also, your diabetes should be well controlled.  
Omar E. Awad, MD:
But the medications listed don't mean you can't have LASIK.  I think there is lots of HOPE for you!  Best to you!
Seininya:
My prescription is pretty high, i.e 10.75. Is it still possible for Lasik? I heard doctors won't perform Lasik for people with high near sightedness. Additionally I heard there's Lasik level 2 for people with higher prescription, is this true??
Omar E. Awad, MD:
Your prescription is a the high end of what we will treat with LASIK.
Omar E. Awad, MD:
Your eye examination will determine if you would be a candidate or not.  One important factor is the thickness and shape of your cornea.  If you have a really thick cornea, you may be a candidate for laser vision correction.  If your cornea is not thick, you might consider a phakic lens implant to correct the nearsightedness.  Good luck@
TXfrank:
I wear bifocals now -will I still need to wear reading glasses after if I have LASIK?
Omar E. Awad, MD:
If you treat both eyes for distance vision using LASIK, then you will likely need reading glasses for near work.
Omar E. Awad, MD:
Some people will consider monovision - a procedure where we correct your dominant eye for far vision and your non-dominant eye for near vision.  If you did this, it would reduce your dependence on reading glasses.
sk123:
What is considered dry eyes? I had the litmus papers put into my eyes and I think the doctor said they should measure a 15. But one eye measured a 3 and the other measured a 1. Is there any hope for lasik?
Omar E. Awad, MD:
The litmus paper is a test of tear production called a Schirmer test.  It measures how much tears you make in a certain period of time (usually 5 min.)
Omar E. Awad, MD:
The test can be done either with numbing drops - which tests your baseline tearing, or without numbing drops - which tests both baseline and reflex tearing.
Omar E. Awad, MD:
If you had 3 mm and 1 mm of wetting in 5 minutes, this is considered low tear production.  I would pre-treat for dry eye, and if this improved, I think there is hope for LASIK for you.
paulab333:
How long does the actually surgery take? How long for recovery?
Omar E. Awad, MD:
The surgery usually takes about 10 minutes or so for both eyes.  It's pretty quick.  Go home afterwards and take a nap, as the eyes begin to heal right away.  Most of the healing occurs in the first 1-2 days, but full healing of the cornea can take several months.
paulab333:
Can I have both eyes done with Lasik at the same time or is it typically two different appointments?
Omar E. Awad, MD:
We give our patients the option of both or one at a time.
Omar E. Awad, MD:
Most patients will choose both eyes at the same time, for convenience reasons (fewer visits to the doctor, both eyes are healing at the same time).  But you can do it either way.
des900:
Can the suction pressure create debris in cornea, anterior or posterior chamber of eye other than usual vitreous floater ?
Omar E. Awad, MD:
When creating a cornea flap for LASIK, there is a device that holds the eye steady with pressure.  This pressure does not cause debris.
Omar E. Awad, MD:
It is possible to get debris under the cornea flap, which a meticulous surgeon will usually spot and remove before you go.  You cannot get debris in the anterior or posterior chamber from LASIK.
Omar E. Awad, MD:
Floaters in the vitreous can happen at any time, whether the eye is pressurized or not.  The pressure used for LASIK is similar to the about of pressure from rubbing your eyes.
