To keep your Phoroptor in perfect operational condition and add to instrument life, review this section
of the instruction manual carefully. It will aid you in performing a few basic servicing tasks and help you
derive full value from your instrument.
CAUTION: IN ORDER TO KEEP THE LIMITED LIFETIME WARRANTY CURRENT, THE PHOROPTOR
MUST BE SENT IN FOR CLEANING TO REICHERT OR A REICHERT AUTHORIZED DEALER
FOR CLEANING ONCE EVERY THREE YEARS.
Cleaning
Make it a habit to always keep your Phoroptor covered when it is not in use. The Dust Cover provided
will aid in keeping lenses clean and keep dust from working inside the instrument and eventually con-
taminating the lubricant. Keep the exterior surfaces clean by periodically wiping it with a clean, dry cloth.
If there are stains that are hard to remove, moisten the soft cloth with a mild soap solution (1 cc of liquid
dish soap to one liter of clean, filtered water (filtered below 5 microns)).
CAUTION: DO NOT DRIP ANY FLUIDS INTO THE PHOROPTOR OR DAMAGE TO THE INSTRUMENT MAY OCCUR.
CAUTION: DO NOT USE ALCOHOL OR ACETONE. STRONG SOLVENTS CAN DAMAGE THE FINISH.
Note:
All lens disc apertures are “open” when the Sphere Power Scale and Cylinder Power Scale read
zero and the Auxiliary Lens Dial Knob is set at “0”.
CAUTION: DO NOT TEST FOR AN OPEN APERTURE BY INSERTING FINGERS IN THE APERTURE AS LENS SUR-
FACES CONTACTED WILL BE SOILED.
Sanitary Face Shields
The semi-permanent Face Shields furnished with the Phoroptor are made of white nylon and have a
protective lens on them to help keep the inside of the Phoroptor free of contaminants. This material
can be washed with a mild soap solution (1 cc of liquid dish soap to one liter of clean, filtered water
(filtered below 5 microns)), or wiped with alcohol.
Note:
If using alcohol, be careful not to soak the lens, and the area where the lens is attached to
the plastic. The alcohol may weaken the glue, causing the lens to fall out.
Note:
Do not press hard on the glass when cleaning. This may cause the lens to fall out, or fall into
the Phoroptor.
Cleaning the Lenses
All lenses should be kept clean and free of dust, fingerprints, etc. How rapidly lenses become soiled
depends on many factors; whether the office has air conditioning or windows are opened for ventila-
tion, adjacency of industry, humidity, etc.
Suggestions are offered here for the self-cleaning of lenses. It is advisable, however, to have the
lenses cleaned approximately once a year by a Reichert authorized Dealer. It is generally good pre-
ventative maintenance to have mechanical assemblies cleaned and re-lubricated at the same time.
There are protective lenses on the front (doctor’s) side of the Phoroptor in both the left and right ap-
ertures. These lenses are held in place by a rubber O ring, and should be removed before cleaning
the internal lenses. Clean these lenses before inserting them back in the Phoroptor with the follow-
ing procedure.
