FAQs / Is There a Possibility That, If During Surgery a Canaloplasty Was Deemed Impossible,  This Other Procedure Could Be Done Instead? What Percentage of Closure Is Significant?

• What percentage of closure is significant?
• I have PAS and this is the problem with the angle. Can the PAS be surgically removed just before a canaloplasty is done, or is this too complicated?

I know these are detailed questions but nobody I’m seeing knows much about canaloplasty. I live in NY but would travel to CA for surgery if need be.

ANSWER:

Dear ******,

1. Canaloplasty can be performed after a corneal transplant, it does require an open angle. Canaloplasty would be unlikely to work in someone with any significant closure of the angle.
2. There are some who feel that any closure is significant and would significantly decrease the likelihood of a successful canaloplasty.  Really, no one knows for certain if a mild amount of closure would be acceptable. My sense is that under 10% would probably be OK if it does not block the canal (which cannot be known until the time of surgery).
