36-exposure and 24-exposure canisters of Ektachrome 100 film for each patient
are sent to each CLEK Participating Clinic by the CLEK Photography Reading Center.
The film should be stored in a cool, dark, dry place.
The film canister (the Ektachrome metal canister, not the plastic container)
should be labeled with the type of visit, the site ID number, the patient ID number, the
date of photography, and the photographer certification number.
The 36-exposure roll is for fit/fluorescein pattern of the habitual rigid lens fit and
for corneal parallelepiped photographs according to the protocol in Chapter 11 of this
Operations Manual.
The 24-exposure roll is for the corneal oblique photographs, the First Definite
Apical Clearance Lens photographs, and the lens 0.2 mm flatter than the First Definite
Apical Clearance Lens photographs.
Note: If the patient blinks during photography and more photographs will be needed to
complete the left eye’s corneal photography (ie, the 36-exposure roll has been used up
before all the photographs have been taken), the beginning of the 24-exposure roll
should be used. The First Definite Apical Clearance Lens photograph series then
follows the oblique corneal photographs on the 24-exposure roll.
After removing the film from the camera, it is placed in a preaddressed, postage
paid mailer provided by the CPRC. The Photographer or Study Coordinator completes
the Clinic Photographer’s Film Log, which is faxed to the CPRC at (614) 688-3285. Any
exceptions to the photography protocol (eg, no habitual fluorescein photographs
because the patient does not wear contact lenses, no FDACL because one eye is grafted,
etc.) are noted on the Clinic Photographer’s Film Log before faxing. The film in the
mailer is mailed to the CPRC the same or the next working day.
