FAQs / SLT and Canaloplasty

QUESTION:

I have heard if I did the SLT then there is a chance the Canaloplasty surgery may or may not be successful due to the possible scar tissues caused by SLT.

Thanks you in advance for any help on this matter so I can make the right decision.

ANSWER:

Prior SLT is rarely an issue with canaloplasty. It is ALT (Argon Laser Trabeculoplasty) that tends to be a problem due to scarring/adhesions that form after the thermal laser treatment. This can result in difficulty achieving 360 degree catheterization of the canal at the time of canaloplasty.

The exception to SLT being a “non-issue” is when an inexperienced (or uninformed) surgeon uses too high a power setting for SLT. This can result in weakness of the inner wall of the trabecular meshwork and even some focal scarring. Very little energy needs to be applied for SLT to be effective. Above the therapeutic amount, more SLT energy only increases risk without additional IOP lowering benefit.
