Contact Lens Follow Up Examination Flashcards
(41 cards)
What does SOAP stand for?
- Subjective history findings
- Objective Clinical Findings
- Assess what was discovered in the subjective and objective assessments
- Plan appropriate steps for the patient
Symptom Checklist: “Burning when inserted”
Check for solution sensitivity
Symptom Checklist” Burning after hours of wear”
Check for dryness, tight fit, and poor movement
Symptom Checklist “Excessive Blinking”
Check for Damaged lens, lens awareness
Symptom Checklist: “Excessive Tearing”
Check for Damaged lens, debris, dirt on the lens
Symptom Checklist: “Foggy Vision”
Check for edema, film on the lens, dirt on the lens.
Symptom Checklist: “Flare”
Check that the OZ is not too small for the pupil, or a decentered lens
Symptom Checklist: “Ghost Images”
Check for residual astigmatism, warped lenses, oily film on the lens
Symptom Checklist: “Headache”
Check for the incorrect power and edema
Symptom Checklist “ Itching”
Check for allergic reaction
Symptom Checklist “Pain after hours of wear”
Check for poor fit
Symptom Checklist “Pain upon insertion or sudden onset”
Check for debris, damaged lenses
Symptom Checklist “Photophobia”
Check for edema, corneal abrasion, dirt on the lens
Symptom Checklist “Poor overall visual acuity”
Check for Lenses eye for eye, dirt on the lens, or the wrong power
Symptom Checklist “Poor visual acuity at near”
Check for wrong power, latent hyperope, early presbyope
Symptom Checklist “Scratchy”
Check for debris, damaged lens, lens deposits and edge lift
What are the two additional tests that should be preformed after the over refraction at the second visit?
Fogging and Duochrome Test
Describe Fogging
Fogging is adding plus sphere power (via flippers) to control accommodation. If the eye is fogged, and the eye still accommodates, this is the desired outcome.
Duochrome Test
Red/Green tests, helps determine the final sphere power of the contact to be selected.
Cover one eye, ask if the letter is clearer on either the red or green side. If green is clearer, add +0.25 until both sides are the same. If the red is clearer, add -0.25 until both sides are the same.
What is the minimum amount of time extended wear lenses should sit on a patinet’s eyes prior to a follow up?
Six hours
What are the main points to check during the slit lamp eval with extended wear lenses on the eyes?
- Movement
- Centration
- Check front ocular lens surface
- Cornea/lens relationship
What is the measurement of the amount of movement needed for adequate tear pump?
.02-.05mm
when checking centration with the slit lamp, the optical zone should be large enough to..
cover the visual axis to reduce flare. Check using diffuse illumination and low magnification
When checking the cornea/lens relationship of RGP lenses, what is the fitter looking for?
- Normal Fluorescein pattern
- Check for air bubbles after blinking
- Depth of the lacrimal lens
- Tear Quality
- Areas of excessive clearance
Best viewed with narrow slit lamp beam and white light.
