Dry eye after cataract surgery

Just saw another study about this. Risk factors for having persistent dry eye at three months after cataract surgery included a baseline OSDI score greater than 12. I'm really pleased that more and more studies are being done about dry eye and cataract surgery, and at the same time concerned that cataract patients are not getting screened for dry eye and counseled adequately about dry eye and treatments before surgery.

Dry eye wisdom from a peer

DryEyeZone forum user pythonidler recently shared, on DryEyeTalk, a veritable dry eye library based on personal experiences over a long journey through dry eye. There's a tremendous lot of information packed in the post, and it's well worth a read! "What you need to know about computer-induced dry eye"

Patient-run FB group on dry eye + nutrition

Check out Healing Dry Eye with Nutrition! This is an FB group led by Sara Thackeray, who had a long and difficult journey through dry eye at a young age and has come out the other side thriving. 

Did you know?

(Nuggets from my favorite bedtime reading, TFOS DEWS II, that vast, intimidating dry eye compendium containing so much information that is directly relevant to you, but which your eye doctor may or may not know yet.)

...there are 12 entire categories of eyedrops, yes, eyedrops, "considered to cause or aggravate dry eye". (TFOS DEWS II Iatrogenic Dry Eye report, table 4.) These include 5 classes of glaucoma drugs; allergy drops; decongestants (a/k/a get the red out); antivirals, miotics; mydriatics; cycloplegics; anaesthetics; and non steroidal anti inflammatory drops. And while some of these drugs may be, in themselves, drying, the fact is, the vast majority of them are preserved with BAK (benzalkonium chloride) which is known to cause and aggravate dry eye. It's time we put more pressure on industry to stop causing dry eye with one division while they treat it with another. We need to be pushing for preservative free alternatives. incredibly complex our tears are? 15 authors, 38 pages, 626 medical references and an awful lot of unpronounceable words to summarize what we know about our tears. (see TFOS DEWS II Tear Film report)

...whole body dehydration increases tear osmolarity (the opposite of what you want). There is not a lot of conclusive evidence about the connection between hydration and dry eye, but clearly, it can't hurt to make sure you're getting the full amount of fluids you need each day! (see TFOS DEWS II Management and Therapy report, 6.1)

...Schirmer (strip) test without anaesthetic is not a good diagnostic measure of tear volume in evaporative dry eye from MGD (TFOS DEWS II Diagnostic Methodology Report, 6.4.2) the last 15 years, a slew of dry eye drugs have been developed but did not achieve FDA approval - for reasons possibly not directly related to whether they actually work. (TFOS DEWS II Clinical Trial Design, 5.1.1)

Prose & Scleral Lens Product News

PROSE & scleral lens care news

  • Purilens drop-shipping! I mentioned in the last issue some measures we're needing to take to manage resources better. One of those is having Purilens shipped to you directly from the manufacturer. We will still be able to ship urgent saline orders from Poulsbo, but others will go direct. This means all of you on the east coast will be getting your orders faster!
  • Speaking of Purilens: The other day, someone was complaining on email about how Purilens caps never puncture the bottle straight and always end up squiring sideways. I told her, truthfully, I always heard that (and frequently experienced it personally) with the old Unisol 4, but almost never with Purilens. As luck would have it, only a day or two later, what do you think happened when I opened a new bottle of Purilens? Crooked puncture and it squirted straight at my shirt instead of my lens.
  • Preservative free saline guide: If you're not familiar with all the options, it's worth perusing.
  • Hydra PEG coated lenses: Are you using the right cleaner? I posted about this on the shop blog recently, but noticed today that Contamac (manufacturer) removed the document we were referencing. Here's Tangle Science's advice on what cleaners to use for Hydra PEG coated lenses.

Refresh PM is (of course) still on backorder. I'm refraining from snarky comments this week, but no promises for the future. Click here for information on substitutes.

Lid care news

Are you looking for a new lid hygiene product to try? You might want to try one of the following with tea tree oil. There are a lot of choices around today! I've always loved Eye Eco's foam, and it's pretty economical. WeLoveEyes foam is popular too, and Oasis' tea tree lid scrub (which seems pricey at $44.95 but contains 60 wipes) is a great one to try if you don't want the mess of applying foam.

Note from Rebecca

It's more than two years now since I had to completely drop (as in, neglect and ignore) the DryEyeZone website and its forum, DryEyeTalk. I hated having to do so, so badly - and it dragged out so much longer than I ever dreamt. But the saline crisis and everything that did to my business left me no time, strength or energy for anything else except some blogging and some of the really vital extracurricular activities like TFOS DEWS II (which was published last summer). 

So while the business is a time-hog (I have to make it pay for itself, and that's never easy), this year I've finally found ways to compartmentalize more and make time for research and writing and sites again and I AM SO HAPPY about it. Every new thing I get to start, every abandoned project I get to dust off, and every odd hour I get to kick around new ideas, enjoying all the energy that comes from doing things I'm passionate about... it just feels so good.

The new DryEyeZone site is coming along nicely and is still on target for rollout before the end of the month. This week, I also finally logged back in to the DryEyeTalk forum and started looking around to see what repairs, reorganization and redecorating need to happen. There's a lot to do. And the forum is a lot quieter than it used to be - due in part of course to so many people having migrated to the Facebook dry eye groups (ours and others). In fact, I've occasionally wondered if the Facebook groups would just make the forum redundant. Facebook groups are really handy for immediate feedback, whether you're a dry eye patient needing support or a scleral lens user with a question or quasi-emergency. I was so touched recently seeing someone in the LA area post that they were out of saline and their shipment was delayed... several local people offered to meet up and share theirs. People are so great!

The more I see, though, the more I feel confident that there still really IS a need for a non-Facebook dry eye forum, where discussions can be more in-depth, where conversations don't get buried after a day or two, and where it's perhaps at least a bit easier to search for detailed information on specific treatment and disease topics.

So I'm pondering, and reaching out for feedback, on changes that would be helpful, including inviting doctor participation. If you have a moment, come visit, see what you think, and let me know any suggestions!

Be well, everyone.
