ABO NCLE EVALUATION SET QUESTIONS AND
ANSWERS SURE A+
✔✔What are the components of the posterior segment of the eye? - ✔✔The posterior
segment includes the lens, ciliary body, vitreous humor, retina, fovea, rods, cones, optic
nerve, and visual pathway.
✔✔What is the purpose of the slit lamp? - ✔✔The slit lamp is used to examine the
anterior and posterior segments of the eye for abnormalities.
✔✔What is the significance of coding in ophthalmology? - ✔✔Coding is essential for
billing, insurance claims, and maintaining accurate medical records.
✔✔What are universal precautions in ophthalmic practice? - ✔✔Universal precautions
are guidelines to prevent the transmission of infectious diseases in healthcare settings.
✔✔What is the purpose of a radiuscope in contact lens fitting? - ✔✔To evaluate and
verify the curvature of contact lenses.
✔✔What does a lensometer measure? - ✔✔It measures the power of lenses and
verifies their prescription.
✔✔What are some examples of verification instruments for contact lenses? -
✔✔Thickness gauge, measuring magnifier, diameter gauge.
✔✔What standards must contact lenses comply with? - ✔✔All ANSI Z80 standards.
✔✔What factors are relevant to successful contact lens wear? - ✔✔Lifestyle, medical
history, motivation, and relationship between corneal measurements and lens
parameters.
, ✔✔Name a special lens design used in contact lenses. - ✔✔Lenticular, torics,
bifocal/multifocal, aspheric, hybrid, scleral, quadrant specific, orthokeratology.
✔✔What does Dk represent in contact lens materials? - ✔✔Oxygen permeability.
✔✔What is the significance of the wetting angle in contact lenses? - ✔✔It affects the
lens's ability to maintain moisture and comfort.
✔✔What is the central posterior curve (CPC) in contact lenses? - ✔✔It is the base curve
of the lens that determines its fit on the cornea.
✔✔What is the purpose of fluorescein pattern evaluation? - ✔✔To assess the fit and
movement of contact lenses on the eye.
✔✔What are some subjective findings to evaluate during follow-up? - ✔✔Dryness, lens
awareness, fluctuating or blurry vision, pain, photophobia.
✔✔What is a common objective finding in contact lens evaluation? - ✔✔Corneal
staining or corneal edema.
✔✔What is the purpose of a follow-up visit for contact lens patients? - ✔✔To ensure
long-term success and address any issues with lens fit or comfort.
✔✔What is the importance of documentation in contact lens fitting? - ✔✔To track
changes in lens parameters and patient health over time.
✔✔Which disinfecting agent is recommended for patients with allergic reactions? -
✔✔Hydrogen peroxide.
✔✔What is the recommended action if eyelashes rub against the back surface of
lenses? - ✔✔Increase the vertex distance.
✔✔What does a +1.00 cylinder at axis 090 indicate? - ✔✔100% of the cylinder effect is
at that axis.
✔✔What is the tolerance for the cylinder axis in a prescription? - ✔✔Typically 2 to 7
degrees, depending on the lens specifications.
✔✔What is the effect of a flatter base curve on lens fit? - ✔✔It can lead to less corneal
coverage and potential discomfort.
✔✔What is the role of solution compatibility in contact lens care? - ✔✔To ensure safe
and effective cleaning and maintenance of lenses.
