There are two elements in lens artifacts that must be considered: oils and salt
crystals.
Always wash your hands before cleaning a lens to get the oils off them, or you
will be adding as much as you subtract!
Salt crystals come from tears and are the usual culprit in scratching the
objective lens. We first breathe hot air on the lens to cause condensation,
then GENTLY wipe center to edge with a clean cotton ball. Do this repeatedly
with a FRESH cotton ball after each pass (never reapply the same cotton ball
once you have removed it from the lens. Do not press hard on the lens! Tears
also have oils in them, so...
Oils are impossible to completely remove without using some sort of solvent,
and come from tear film, noses and fingers. We use reagent grade methanol (a
type of pure alcohol) on cotton balls. Apply a drop or two to a ball, wipe
lens, throw out cotton ball, repeat. Finish with hot breath and a dry ball.
Eh, Voila!
Using these guidelines we have not scratched a lens in 30 years. We used to
scratch lenses like mad when we were dumb enough to use Kodak lens tissue!

Dear Ophthalmic Imaging Community:
Much talk on Optimal re: Manuals. Those of you regularly checking the OPS
website will see a blog I wrote regarding this project. In a nutshell:
I am the keeper of the OPS Historical Archives
As part of this project, I collect manuals of all things Ophthalmic Imaging.
They have come in very handy over the years to our membership, as well as
providing a historical footprint of where we started and how far we have come.
So, any and all PDF files of imaging instruments are welcome. You can assure
the vendors that our intents are pure.
I have a YOUSENDIT account. PDF's may be sent to me in this manner. Hospital

Subject: [optimal] Fundus camera cleaning regimens
Hello OPTIMAL,
I am wondering if anyone has a set protocol for cleaning fundus cameras.
Specifically, how often do you clean the front objective lens, and what
methods do you use? We recently discovered that one of our camera lenses
was badly scratched from someone cleaning with something abrasive
(seriously looks like it was done with sandpaper..thankfully it does not
affect the image at all in most cases)
Any other tips on camera cleaning and maintenance would be welcome!
Thanks very much!

Noelle,
We recommend first using a blower to remove any dust/particles that may damage
the objective lens.
You can then use a lens cloth and denatured alcohol. Do NOT use isopropyl
alcohol or other harsh cleaning chemicals, which can remove the coating on the
outer surface of the objective lense.
Sincerely,
Hugo Hur

I'm sure you can see the scratches on a poorly dilated pt though. Man! Tough

You can always do the hot breath method w/a lens cloth which works pretty good

Does anyone know of a fluorescein dye manufacturer that will ship to canada
other than eye supply. We currently purchase our supply from Eye supply zin
Tampa, Florida however they`re charging us $141 per box (12x5mL) of 10% dye.
They`re also not able to ship the amount we`re looking for because they don`t
have enough stock. We typically purchase about 100-150 boxes every 3 months.

I've been using hot breath and�a clean cotton ball for 11 yrs with no problems.
Sometimes I'll puff it with canned air afterwards
to get�the little�cotton hairs off. The most stubborn nose grease smears may
take two times to fully clean. I've never had any
scratched or marred lenses. Some of my photo staff insist on using lens wipes,
but I think they're a waste of money.

Subject: [optimal] Re: Fundus camera cleaning regimens
From: Marshall Tyler <marshalletyler@xxxxxxxxx>
Fundus camera objective lens cleaning:
Break down the problem to get to the correct solution.
Coated or uncoated lens? Old 30degree Zeiss is uncoated.
Front or rear (inside the camera) side of the lens? Is the lens removable?
What (dirt) are we removing?
Tear film, flicked spots from eyelashes? These are WATER Soluble so use
soapy water first!!
Grease spots: kids fingers or nose prints? Then proceed with the either/
alchol mix IF uncoated lens.
as said by someone else, MAKE your own real-cotton Q-tips using a wooden
stick from a manufactured cotton-stick thing. Why not just use the pre-made
ones?? 'cause they have GLUE which will be dissolved with our
non-water-based cleaners.
If Coated lens, check with the manufacturer for safe protocol.
Canned "air" is pretty dirty stuff and high powered. If you must use it,
shoot it across the lens to have the venturi effect lift the dirt off of
the lens, not shove the dirt into the coatings.
Dust: use a non-brush hand air blower (baby snot [nose stuff] remover bulb)
bulbs with brushes WILL get grease on them IF they are not locked up.
(nurses and Drs just can't keep their fingers to themselves - they just
don't understand that that nice little brush is High-tech cleaning
equipment until it is greased up and useless.
BTW, Zeiss has a nifty hand spun turntable for their little lens. The
JOPhas a very old article on using a kids record player to automate
this task.
Zeiss has a lens cleaning set: 000000-1216-071
I think that you can only order 3 at a time and must ship via ground.
Pretty flammable stuff! Too many oz of stuff cannot be put into a box.
Either (and many of the volitale cleaners), when left open will absorb
water from the room air. So, open the container, tip a bit into a
shot-glass sized container, and reclose the original bottle right away.
Some lenses have a little black dot on the back of the lens - this is an
anti-reflection reducer (remember the double light reflex when you use an
indirect ophthalmoscope? Anyway, you can remove (as reported by many years
ago by an over-diligent photographer, it BUT the lens will then need to be
replaced.
Well, that is all for now, time for rest so I can go sailing!
