Revision Flashcards
SOAP
Subjective(questions) Observe, Assessment, Plan
this Pt requires more frequent follow ups
first time extended wear/GP users
symptoms: excessive tearing, red in cunjunctiva, swollen eyelids, photophobia, blurry vision
corneal ulcer
Pt sleeps w/ CL or not caring for CL like instructed
corneal ulceer
small, whitish “blobs”
are a collection of white blood cells
early sign something is wrong with cornea
corneal infiltrate
blepheritis, chemical sensitivity from lens soluction
“causes” of corneal infiltrate
inflamation of the eyelids
blepheritis
symptoms: foreign body sensation, photophobia, red eyes, excessive tearing
corneal infiltrate
improper use of tap/distilled water to clean lens
Wearing Cl when swimming, showering/bathing, or in hot tub
Acanthamoeba keratitis
symptoms: severe eye pain, redness, excessive tearing, blurred vision, photophobia, foreign body sensation
acanthamoeba keratitis
symptoms: eyes feel scratchy, and dry, Cl are not comfortable, visible redness on horizontal areas
9 and 3 o’clock staining
surface scratches caused when foreign debris is trapped on cornea beneath a CL
foreign body staining
symptoms: gritty, sandy, burning, scratchy sensations on eye(s). Conjunctiva may be red or irritated
dry eye
papillae on underside of eyelid are enlarged and red
giant papillary conjunctivitus
mechanical rubbing of palpebral conjunctiva(due to CL wear is too long/ wearing longer than prescribed/ wearing dirty/poorly cleaned CL)
some solutions due to chemical composition
causes of GPC
symptoms: itching, mattering, foreign body sensation, conjunctival injection, dryness
GPC
Pt is myopic(-) in one eye and hyperopic(+) in the other
antimetropia
image in one eye is seen significantly larger in one eye than the other
aniseikonia
eyes have unequal refractive powers
anisometropia
serious condition specifically for infants and young children as it can lead to amblyopia
anisometropia
uncorrectable loss of vision in eye that appears to be normal
this can be due to suppression by the brain
amblyopia
1-2 week, 3-6 month follow ups
new daily wear Pts
1 day, 3 day, 1 week, 1 month, 3-6 month follow ups
new extended wear soft CL Pts
annual follow up
existing daily wear Pts
2-3 times a year follow ups
existing extended wear Pts
symptoms: discomfort on lens insertion, excessive movement, edge lift, lag on upward gaze
loose/flat soft CL
mires are clear, blurry when blink, then become clear again
loose/flat soft CL
symptoms: discomfort on lens insertion, decreased vision, excessive movement
there may be no symptoms
everted(inside out) lens
symptoms: lens awareness/discomfort
excessive movement, lens lag, edge bubbles, lens rides high attaches to upper lid then drops
loose/flat GP lens
symptoms: discomfort on lens insertion, burning, redness, eye itching
irritation from solution
symptoms: eye redness, excessive tearing, blurred vision, photophobia, severe pain, eye discharge
microbial keratitis
discomfort after a period of wear, scleral indentation, burning/stinging, fluctuating vision, redness
tight/steep soft lens
mires are blurry, are clear after blink, become blurry again
tigh/steep soft lens
if corneal cylinder is >2.5D
GP bitoric lens
corneal astigmatism is <2.5D and refractive astigmatism is not the same amount as corneal astigmatism
GP front toric lens
taco test
determines if lens is correct orientation or if it’s everted(inside out)
replace cases every
1-3 months
replace solutions every
30 days
corneal layer responsible for maintaining proper hydration level
endothelium
disinfectant chemical safe to use with soft contact lens
polyquatermium 1
when soft contact lens wearer reports difficulty with near vision, but is fine with distance
over corrected
Pt’s health history as a temporary contraindiction to use of contact lenses
acute conjunctivitis
during long periods of non-use; rigid lenses should be stored in
a dry state
this instrument can simultaneously measure/evaluate diameter, optic zone diameter, and surface condition of GP lens
measuring magnifier
this lens tint changes color of light irises but doesn’t impact dark irises
enhancement tint(s)
V-channel/slot gauge measures
GP lens diameter
soft multifocal contact lens design where there is a gradual power change from center to edge of optic zone
aspheric design
decreasing overall diameter and flatten BC will
effectively loosen/flatten CL fit
increasing overall diameter and steepening BC will
effectively tighten/steepen CL fit
“Dominate eye” is fit for distance and “non-dominate eye” is fit for near
monovision
surface, wing, basal
cell types found in epithelium
characterized by puffy lid margins and dandruff like scales
blepharitis
higher power =
steeper curve
lower power =
flatter curve
separate areas for distance and near
concentric design
lenses move to use distance or near
translating/alternating design
look like a bifocal lens on cornea
translating/alternating design
