Eye and Vision: Orthokeratology
Ophthalmologic Issues Addressed by FAA
Excerpts from Guide for Aviation Medical Examiners
Application Process for Medical Certification
Exam Techniques and Criteria for Qualification
Items 31-34. Eye - Orthokeratology
Orthokeratology is acceptable for medical certification purposes, provided the airman can demonstrate corrected
visual acuity in accordance with medical standards defined in
14 CFR part 67. When corrective contact lenses are
required to meet vision standards, the medical certificate must have the appropriate limitation annotated.
Advise airmen that they must follow the prescribed or proper use of orthokeratology lenses to ensure compliance
with 14 CFR
61.53. Airmen should consider possible rotation, changes, or extensions of their work schedules when deciding on orthokeratology retainer lens use.
For guidance regarding the conduction of visual acuity, field of vision, heterophoria, and color vision tests, please refer to Items 50-54.
The FAA specifices that the examination of the eyes be directed toward the discovery of diseases or defects that may cause a failure in visual function while flying or discomfort sufficient to interfere with safely performing airman duties.
The Examiner should personally explore the applicant's history by asking questions concerning any changes in vision, unusual visual experiences (halos, scintillations, etc.), sensitivity to light, injuries, surgery, or current use of medication. Does the applicant report inordinate difficulties with eye fatigue or strain? Is there a history of serious eye disease such as glaucoma or other disease commonly associated with secondary eye changes, such as diabetes? (Also see Item 53 and Item 54).
