What factors are relevant to successful contact lens wear? -ANSWER-Lifestyle,
medical history, motivation, and relationship between corneal measurements and
lens parameters.
Name a special lens design used in contact lenses. -ANSWER-Lenticular, torics,
bifocal/multifocal, aspheric, hybrid, scleral, quadrant specific, orthokeratology.
What does Dk represent in contact lens materials? -ANSWER-Oxygen
permeability.
What is the significance of the wetting angle in contact lenses? -ANSWER-It
affects the lens's ability to maintain moisture and comfort.
What is the central posterior curve (CPC) in contact lenses? -ANSWER-It is the
base curve of the lens that determines its fit on the cornea.
What is the purpose of fluorescein pattern evaluation? -ANSWER-To assess the fit
and movement of contact lenses on the eye.
What are some subjective findings to evaluate during follow-up? -ANSWER-
Dryness, lens awareness, fluctuating or blurry vision, pain, photophobia.
,What is a common objective finding in contact lens evaluation? -ANSWER-Corneal
staining or corneal edema.
What is the purpose of a follow-up visit for contact lens patients? -ANSWER-To
ensure long-term success and address any issues with lens fit or comfort.
What is the importance of documentation in contact lens fitting? -ANSWER-To
track changes in lens parameters and patient health over time.
Which disinfecting agent is recommended for patients with allergic reactions? -
ANSWER-Hydrogen peroxide.

effect is at that axis.
What is the tolerance for the cylinder axis in a prescription? -ANSWER-Typically 2
to 7 degrees, depending on the lens specifications.
What is the effect of a flatter base curve on lens fit? -ANSWER-It can lead to less
corneal coverage and potential discomfort.
What is the role of solution compatibility in contact lens care? -ANSWER-To
ensure safe and effective cleaning and maintenance of lenses.
, What are the signs of contact lens-related complications? -ANSWER-Corneal
staining, injection, discharge, and vision loss.

indicates the stiffness of the lens material.
What is the purpose of changing lens parameters during follow-up? -ANSWER-To
improve fit, comfort, and visual acuity based on patient feedback.
What is the recommended follow-up protocol for daily wear contact lenses? -
ANSWER-Regular assessments to monitor fit and comfort.
What are the common adverse reactions to contact lenses? -ANSWER-Redness,
discomfort, and allergic reactions to solutions.
What is the purpose of a thickness gauge in contact lens evaluation? -ANSWER-To
measure the thickness of the lens for proper fitting.
What is the significance of the edge design in contact lenses? -ANSWER-It affects
lens movement and comfort on the eye.
What is the role of patient motivation in contact lens wear? -ANSWER-It
influences compliance and successful adaptation to lenses.
