    • Harry Chilingueria : Awesome Cindy, I have signed up for the Vision Canada convention and like last year I look forward to the content and will be especially interested in your lecture, can't wait. :)
    • Cindy K : Harry- yes we're doing the Virtual Convention- here's the link:«link» I've also put this on Optiboard under heading of Professional and Educational Discussion Forums. And, BTW, I'm presenting my favourite workshop, MCE on a Budget (explains in detail the mechanics and means to develop study groups). and, thanx for the web content info- I see several things I'm going to get onto our website! And I'll be certain to credit all as appropriate.
    • Harry Chilingueria : Oh and Cindy if you guys are doing the virtual convention please send me a link so Icould check out who you got this year as I would be real interested.
    • Harry Chilingueria : Cindy K, no protocal for using the content from this site, but the images are from NIH, which does require a reference back to them, just do a Google search for NEI at NIH and check out their resources. The simulators are from Alcon and they have said as long as it's for a non profit or educational they are fine to use. The posts and content are mostly written by me and compiled from various sources, you are free to use them to your hearts content.
    • Cindy K : What is the protocol here for using material from this site on our association website? Please advise
    • Cindy K : Harry- are you going to do the Vision Canada Virtual Convention again this year? I see what I'm assuming is an old post you made on the subject. The lineup is great this year, and bonus, I get to present one of my favourite lectures there

It is a database with all contact lens parameters, price, and manufacturer contacts.

So keep coming back I have more resources and software coming.

    Vertex Compensation

    Dc=compensated Rx
    D=original Rx
    d=vertex distance change

    Dc=D/(1-d*D)

    Note: change in vertex distance is in meters and the sign is negative if moving away from the eye and positive if moving towards the eye.
