GSLS Part 7 - Care and aftercare of scleral lenses

Posted by Rebecca Petris on

General Session: Care and aftercare of the specialty lens This session was moderated by Eef van der Worp, who provided context for us about risk issues for specialty lenses (note: I only reported on the scleral lens aspects) stemming from things like lens handling, care and maintenance. One of the things that he highlighted is that our lack of knowledge about actual incidence of things like microbial keratitis (we don't have enough history with the lenses and case reports etc) has implications for whether it is appropriate and ethical to use these lenses on normal, perfectly healthy eyes, as opposed...

GSLS Part 6 - Dr Lynette Johns talk on corneal pain

Posted by Rebecca Petris on

"Invisible Pain Syndromes: Why scleral lenses do not always work" This was a course presented by Dr Lynette Johns at GSLS yesterday. Some introductory notes from me first... It was standing room only, there were no tables, and I was so squished I couldn't use my laptop to take notes, so all I have is a lot of hastily scribbled notes that are now very hard to read, and I know I need to go find the course outline and make sure I didn't miss anything. For those who don't know me or my background, I want to emphasize that I...

Posted by Rebecca Petris on

Caveat: Read at your own risk. I am not a doctor. Et cetera. General Session: State of Scleral Lenses The early days of scleral lenses (Lynette Johns) Dr Johns presented quite an interesting history of contact lenses, crediting Tim Bowden's research - and by the way this history is covered in a chapter of the bible, I mean the book on scleral lenses that she and Melissa Barnett have recently published.  She reached all the way back into ancient Egyptian ocular prosthetics made for mummies - since prosthetics are what ultimately what scleral lenses emerged from - then then followed it all through...

GSLS Part 4: Long term scleral lens management (DELECTABLE session!)

Posted by Rebecca Petris on

My eyes ran out of steam Thursday night before I could make translate & transfer my notes into blog form, so I wrote this up in dribs and drabs between sessions on Friday. On re-reading, I decided this particular session really deserved its own separate post, rather than tacking it onto the end of the last one as planned. Long Term Scleral Lens Management This was the highlight of Thursday (apart from great conversations with great doctors!). Every speaker in this session was speaking directly to things I personally care about a lot :)  Lynette Johns First, Lynette Johns gave an overview of the issues,...

GSLS Part 3: BostonSight Scleral; Controversies in specialty lenses

Posted by Rebecca Petris on

So now the fun really starts. My first notes here are from a talk on new technologies in BostonSight Scleral lenses, then the general session with specialty lens controversies. BostonSight sponsored talk "Lumps, Bumps and Scleral Shape: Navigating the Curves with BostonSight Scleral SmartChannel and Eaglet Eye's ESP" Karen Carrasquillo OD So for those of you who aren't familiar with it, BostonSight Scleral is a locally-available less expensive counterpart of sorts to BostonSight's PROSE lenses. This talk was about the technologies available for BostonSight Scleral lenses. I was keenly interested in this because it's pretty new but makes use of data from...
