Saline for Scleral lenses
Posted: Mon 18 May 2015 7:29 am
Hi,
Apologies in advance for the long post....
I have just discovered this forum and spent a quite a while at the weekend reading through posts. I have Keratoconus in one eye only, diagnosed about 10 years ago. I went through the usual glasses, lenses route and had a graft just over two years ago. Vision post graft is slightly improved but still far from good so I need to have a contact lens to correct the vision. I have just been seen by the contact lens clinic at my local hospital and it turns out that, as before the graft I'm unable to wear corneal lenses - they just fall out after a few minutes. Interestingly though, I took along my old scleral lens that I was fitted with at a different hospital before my graft, and after having no luch with the corneal lenses we tried my old scleral lens. The results were quite incredible, with a huge improvement in vision, so I wa advised to start wearing that lens again. So now to the question, what do people use to fill their RGP scleral lenses? I have read many differing opinions about what to fill the lens with before insertion. These range from things like Celluvisc to multipurpose cleaner/conditioners like quattro and I'm now more confused than ever. I seem to remember using large bottles of saline before, but have read a lot about toxic reactions to preservatives and buffers that may be in these. I'm a bit reluctant to use the multipurpose cleaner/conditioner as it seems like the same problem may exist, which has led me to individual saline vials. Amidose and Normasol used to be mentioned regularly on here, which seem to me like a good option but there is not much reference to them for the last few years so I'm wondering if something else is used now instead? Thanks in advance for any suggestions.
