Custom vs Conventional

Postby DryEye » Fri Nov 24, 2006 4:37 pm

In both instances, are the quality of the pictures taken the most important part for one's end result? In other words, if one ends up with some slight astigmatism and slight undercorrection from a custom procedure could it be the result of not perfect preop pictures and that the machine only did what it had in terms of pictures? I ask because I just remembered during another pre-lasik consult an assistant took some of the pictures over due to the fact the doctor was a stictler for pictures. Are these pcitures they take done with an Orbscan? I have had them done during my post visits - Are these the same pics that are taken before lasik is done? What is an Orbscan and what kind of technololgy does it use?
Also, what is considered a good outcome from lasik procedures? Near 0 correction without complications? It obviously has to do with patient satisfaction, but is there also some sort of rule of thumb?
Thanks

Since Lasik is microsurgery on biological tissue, it is my opinion that minor imperfections in outcomes are more likely because of the nature of the surgery than because of any "mistake".

Orbscans are not used to plan the laser ablation pattern for Lasik. They are used as an analytical tool to determine if a patient is a candidate, including diagnosis of potential corneal disease and determination of corneal thickness.

What is a good outcome is a surprisingly dynamic target. 90% Snellen 20/20 or better is a considered a good outcome in a clinical trial, but not for that 10% who didn't achieve 20/20. 3% with unresolved complications at six months postop and 0.5% being serious complications may be considered safe by medical standards, but that is small consolation to the 3% (or worse, the 0.5%) who have complications.

Probably the most dynamic part of what is a good outcome is what the patient expects. Someone who expects that without glasses they will suddenly be popular, will write the Great American Novel, or their mother-in-law will like them are very likely going to have a "bad" result.

I certainly hope someone wouldn't do lasik for the sake of popularity. Talk about a bad candidate. True on patient outcome expectation, but if they saw better in contacts or glasses then i think almost everyone in that predicament would not be happy campers.
