Microkeretome or IntraLase?

Should you choose the Microkeretome or all laser? As with the femtosecond laser, there are arguments between surgeons on whether modern microkeretome blades or intralase is better. Historically, most LASIK problems were related to (a) blade and flap complications, (b) older technologies, and (c) inexperienced surgeons and procedures for unqualified patients.

Nowadays, there are still surgeons who prefer the microkeretome blade over intralase. Studies have shown that laser helps healing faster than some microkeretome, but there are conflicting findings. One thing that is not debatable is that intralase does help improve the flap adhesion better. The inverted bevel of the iFS intralase laser is superior. It's up to you if the quicker healing and stronger strength flap is worth the extra cost for intralase. Only Dr. Bindi and Dr. Manche has the iFS laser as of this writing. Dr. Furlong still uses the FS intralase. Dr. Hyver uses the Ziemer femtosecond laser.

This is a study of the 4th gen FS vs the Ziemer LDV. Another one.

Things to consider is that NASA and the US military only approves intralase and not a microkeretome blade so if you want the military and NASA’s approved method: it’s wavefront-guided LASIK with bladeless flap femtosecond laser.

  1. Hello,
    Thank you for such an in depth blog! I am considering LASIK as we speak and your experience and reference sources are a treasure trove of knowledge.

    I would like your non-medical, personal opinion on the FS60 vs iFS LASERs for flap creation. Is there a marked difference or set of advantages? Would it be prudent to go out of ones way for the iFS given the other technologies are the same (VISX S4 IR)?

    Thanks

  2. Hi LASIKDISCOVERY,

    This study seems to indicate the iFS gave superior results: http://www.escrs.org/milan2012/programme/free-paper-details.asp?id=13742&day=0

    Ditto this one: http://www.escrs.org/milan2012/programme/free-paper-details.asp?id=14536&day=0

    Based on the studies, the iFS laser appears to give better recovery and/or results early on but were comparable at 12 months out.

  3. Thanks. I'm looking to get the surgery done pretty soon. I'll send an update to keep your readers posted on a more recent experience...
