Q:
Good morning , A:
Lasik will not stop the eyes from changing. At your age, you are also about
to start developing some difficulty with close up vision, due to "presbyopia". Email:
August 07, 2005 Q:
I have had x2 consultation's and one Doctor told me that my cornea is thin and
would recommend PRK. The other Doctor told me that that I am a candidate for
the CustomVue Laser surgery. Which form what I have read I believe it would
be a better choice. The only thing is that now I am a bit nervous and scared
to have the CustomVue Laser Surgery. I was told at my 2nd consultation that
my right eye is 526 and left is 530. I am not sure if there is suppose to be
a point after the 5 or not. I don't know if these numbers tell you anything,
because I do not understand how they works, but I was hoping that they would
help in answering my question or maybe explaining to me what the ranges are
and how they work in order to be able to choose between the PRK and CustomVue
Lasik. A:
You can have PRK and CustomVue. These are really two different things. PRK or
Lasik refers to no flap (PRK) or having a flap (Lasik). CustomVue refers to
using the software to run the laser based on the wavefront measurements, which
can be used with PRK or Lasik. Email:
August 07, 2005 Q:
How many times can Lasik be performed on the same eye? A:
There is no definite limit. Email:
August 07, 2005 Q:
A few months ago, I knew about a new surgery procedure, similar to lasik just
just with the difference that the computer follows the eyes movements, making
the risk smaller. I just like to know the name of this procedure and how is
this exactly made. A:
Most lasers used to perform lasik nowadays have trackers, which follow the eye
as it moves. There is also wavefront software, which treats the eye is many
different locations with slightly different prescriptions. Email:
August 10, 2005 Q:
I am currently 31 years old and underwent LASIK surgery in November of 1999
to correct my ¿4.25 vision. My vision for the past five years has been
great. However, over the past year I have noticed that the nearsightedness is
returning. I now have to wear glasses for driving at night. I am seriously considering
having the procedure performed again. Are there any consequences with undergoing
another LASIK procedure? A:
If there is adequate corneal thickness and the other parameters are normal,
enhancements are a safe and effective treatment. Email:
August 13, 2005 Q:
Dear Dr. Caster, A:
No, I have never heard of that. Email:
August 14, 2005 Q:
I am 41 and wear contact lenses and glasses. I can read with my glasses on with
no problem. I have heard that after the surgery there is a good chance I will
need to wear reading glasses is this true. please explain! A:
No, your vision after the procedure should be like it is with the glasses on
at both distance and near. When you get older, with or without the surgery,
you will develop presbyopia. Email:
August 14, 2005 Q:
I had lasik surgery 24 days ago and my left eye especially is still very blurry.
I am starting to get concerned that this is the vision I will be left with as
there has been very little improvement in the past three weeks. My vision is
no where close to being what it was previously with corrective lenses. I am
currently testing at -1.5 and -.5. This is a dramatic improvement from -7.5
and -7 but the blurriness seems almost separate from my perscription, if you
understand what I mean. Should I start to reconcile myself to the fact that
I may still need to where corrective lenses or is there still hope this blurriness
will recede? Thank you. A:
I hope and would expect that it was carefully explained to you that enhancement
procedures are sometimes necessary, and this may apply to you. It is very easy
to perform an enhancement procedure. Email:
August 14, 2005 Q:
I plan to have basic surgery via the Nidek 5000 laser (Myopia -4.75 both eyes
and slight astigmatism). How has this machine performed? How long will it take
the flap to heal? I am also considering whether to pay extra for a year's worth
of enchancement (if necessary), what are the chances that my vision will change
or need to be corrected within a year? I heard that changes mostly happen in
the year. Thanks. A:
The Nidek machine produces very good results for that range of nearsightedness
and astigmatism. Most enhancements are performed within the first year. Email:
August 15, 2005 Q:
I recently decided to look into LASIK vision correction. One of the places I
went performed a series of eye tests to determine my suitablity for LASIK. After
testing I was ushered in to see the "Dr." and he checked my eyes. While doing
so he made a series of comments, to himself, like "yeah I think i see it . .
." Then he tells me I have thinning corneas. Just one year ago I had an complete
eye exam and was not infomed of the thinning corneas. What should I do from
this point? A:
Corneas do not progressively thin, so you had the thin corneas a year ago, but
this test is not commonly performed and is not important unless you are comtemplating
surgery. I would get a second opinion regarding your suitability for laser vision
correction. Email:
August 17, 2005 Q:
Dear Dr. Caster, A:
With Lasik as an enhancement, with custom or conventional software, it is best
if possible to lay back the old flap. PRK will be better in some cases; you
would need a consultation to determine which is best. Flap complications can
happen but are very rare and usually easily treatable. Email:
August 18, 2005 Q:
