Dr. B here, an optometrist who loves baseball, and all things related to eyes. Had the pleasure of meeting the two eye docs who performed the study mentioned in the link below, who are working my dream job of working closely with MLB teams for the past 15 years:

http://www.ncbi.nlm.nih.gov/pubmed/16298317

Basic gist states that no significant improvement in performance could be attributed directly to the LASIK procedure compared to wearing glasses or contact lenses. Subsequent studies by Laby and Kirschen have actually demonstrated a decrease in visual function after surgery, and now their reccommendation is to hold off on surgery until your professional playing days are over.

Vision of course is only one part of the equation for a player like RJ, who could stand to make significant strides just by being up with the big club day after day learning what it takes to be a major leaguer. Just thought I'd throw my 2 cents in.

...after LASIK, Johnson was actually tested for acuity and his eye doc says he's seeing 20/10 now...which jives with his comments about finally seeing the laces on the ball. If he deteriorates after this point, which is possible, I'm not sure you can blame the LASIK.

I love that Johnson is now 20/10. For full disclosure I wish all the players on my teams were using AAS, IGF-1, and insulin, for example.
But, how is going from a deficit to above average, and more importantly above what your own abilities would allow from LASIK kosher but other means are "evil". A bit of consistency would garner the PED's=SATAN crowd credibility they currently lack on multiple fronts.

I don't see why PEDs are evil but unnaturally gifted sight post-surgery is cool.

Which leaves the question as this: was Johnson playing both without contacts and without Lasik in 2008-09, leaving his vision at (say) 20/30?

In your experience, is it likely that a hitter is stepping up there with less than 20/20 vision and unaware of his available remedies?

Johnson did say, wow, I can see the laces now, so apparently he perceives an improvement relative to his own recent past -

The whole subject of optometry could almost be a subject in school :- ) but just real quick Dr. B... Johnson stated that his vision tested as 20/10 after the Lasik.

I'm guessing you could give a contacts prescription that was 20/10, 20/5 or whatever magnification you wanted to... without reading the study above, I assume that the doctors gave whatever prescription they judged best? It wasn't controlled to study a given prescription of 20/20 or whatever?

.............

My first thought would be, if my natural eyes could be corrected to 20/10, that would be much preferable to 20/10 with contacts, just because the contacts move around in your eyes, could give different refractions at changing angles and so forth...

But, as you say, this study got to the bottom line and measured end performance, so if well-designed and with a high coefficient of confidence, then sure...

Wak coming out to defend Bradley, I thought was key. Now Wak has to make Bradley understand, as the rest of the '09 crew did, that player ejections don't help the team. Let the manager/coaches make the arguments.

Perhaps, after having established himself as a reasonable MLB manager, Wak believes he has the credibility he needs to begin to defend his team against the umps. I hope so.

"James has been surprised by Johnson's lack of development with the bat, but hasn't lost confidence that he'll hit eventually."

Send James a video montage of a bunch of fastballs clanking off of Rob's glove and he won't be so surprised anymore. ;)

That's a great visual itself...

You always hear about this Lasik ---- > .300 stuff, but I liked the intersection of James' comment with Johnson's.
