If a new person needs to be certified after Study startup, the CLEK
Participating Clinic Principal Investigator should call the Study Chairman for
certification materials and instructions.
Each person certified in at least one of the key tasks listed above is assigned
his or her certification initials (eg, KSZ) by the Chairman’s Office. These certification
initials are entered on all CLEK Forms as indicated.
12.2 Certification for Visual Acuity Measurement
Visual acuity is one of the most important measures of the CLEK Study. Each
Clinic must have at least two people certified for visual acuity measurement in order
to enroll and follow CLEK Study patients. This person can be either a Clinician or a
Technician.
The certification requirements for visual acuity are:
• To attend a CLEK Study training session concerning CLEK Study design and
methods, visual acuity measurement, and forms completion and data inspection;
• To read the CLEK Operations Manual, particularly Chapter 6, “Vision
Assessment;”
• To review CLEK Study data collection forms, particularly the CLEK Examination
Form;
• To set up a visual acuity testing room following the procedures in Chapter 6;
• To complete a written examination on visual acuity measurement; and
• To complete an in-person or telephone visual acuity training session.
After satisfactory completion of all requirements, verification of certification
is issued and forwarded by the Chairman’s Office to the Coordinating Center and
the Executive Committee. To keep certification current, the certified task must be
performed satisfactorily on at least 10 Study patients in a calendar year.
Annual recertification may be granted at an annual Full Investigators Group
meeting.
