That's critical.
2:14
Yeah, thanks, Jen.

So I think you alluded to one of the sources of dissatisfaction and maybe underutilization of presbyopia correcting lenses is having the wrong lens for the wrong patient that doesn't meet their lifestyle goals and that doesn't match with the health of their eye.
2:33
And so this process is exceptionally important, and it really takes a good amount of time, and it's almost an art to customize presbyopia.

a patient's vision.
2:41
And you got to have a little bit of fun with that.
2:44
So I think there are two components.

We have new options, but how do we decide now? How do we decide between an eat-off lens, a multifocal, trifocal design, a hybrid design? How are you picking? There's almost maybe too many choices now, right?
8:23
And how do we get the word out there?
8:26
Yeah, my goodness, there's so many parts to it.
8:28
I think the first thing to say is that we follow the technology.
8:32
I think that the price behavior correcting IOLs of the present are not those of the past.
8:38
We've gone from refractive IOLs initially to bifocal IOLs with very deep echelons and very clear halos and rings.

trifocal IOLs with very customized, elegantly designed posterior surfaces and hybrid designs to the category of extended depth of focus lenses and non-diffractive extended depth of focus lenses.

And of course, we're seeing continued progress in development amongst our amazing engineers.

Yeah, I
