OMG cheaters cheatings caught inflating post-lasik 20/20!!!

Think you are really 20/20 accuracy after lasik?(UCVA or even BCVA)
Your surgeon or doctor may be doing the following:


1. He let the lasik patent guess the line if he couldnt see it and gave
credit for correct gusses! Often just one or two correct "passes"

2. He may ask you to squint or let you squint

3. Incorrectly calibrated eyechart size and distance. He can easily
make the 20/20 line larger by moving the projector back further or
telling you where to stand which may be a few feet less than the full
20 feet distance!

4. He can leave the bright lights on in the exam room to make your
pupils shrink, resulting in a pinhole effect and making things more
clear. This can often mask residual refractive errors or improve larger
errors.

5. One guy said: In my first exam after the proc I was pronounced
20/20, but I could only see
one letter on the 20/20 line.

6. Eyedrops could be applied immediately before having him read the
eyechart.



omg more cheating!



Getting uncorrected 20/20 out of someone -0.75D off of plano would not
be easy. It would usually require the patient to be squinting and
guessing - never a very good idea. I know some doctors have attempted
to get this kind of result by applying eye wetting drops just before
the Snellen test. This gives the cornea a very smooth surface and
better visual acuity for a minute or two, but is hardly the real
world.


When evaluating our certified surgeons our breakoff point is -0.50D.
We figure anyone over -0.50D cannot possibly have true 20/20 no matter
what theatrics they did for the Snellen test.


my comments: Well it is possible to be 20/20 with more than -.5
diopters but very rare. Youd need a BCVA of better than 20/15 and less
than 2% are this good. If you are told you are 20/20 and more than half
diopter off, be very suspicious. Likley you are really closer to 20/30
if you need -.75 to yield 20/20. Or you could really be 20/20 then -.75
should correct you to like 20/13! Either way, a refractive error of
-.75 without correction means your seeing 2 lines worse.

So, Dr. Psil O. Cybin ...

What are you recommending we do here?

I believe we're all waiting your sage advice.
