Card 1
Question: What initial patient factor is important to assess before contact lens fitting?
Answer: Patient’s motivation (why they want to wear contact lenses).
Card 2
Question: List key benefits of contact lenses compared to spectacles.
Answer: Improved vision in activities, possibly better peripheral vision and cosmetic/functional advantages for sports and recreation (e.g., golf, basketball)
Card 3
Question: What are the main contact lens modalities mentioned?
Answer: Rigid (GP) and hydrogel (soft) lenses; modalities include conventional, daily disposable, weekly disposable.
Card 4
Question: Give three desired material properties for a safe contact lens.
Answer: Inert (chemically and physically stable), nontoxic/biocompatible, wettable and deposit resistant.
Card 5
Question: Name three additional desirable characteristics of contact lens materials.
Answer: Durable, good optical quality, and resistant to deposits.
Card 6
Question: What is an appropriate toric lens choice for a more spherical cornea?
Answer: Front surface toric is better for more spherical corneas.
Card 7
Question: What toric lens design is better for more cylindrical corneas?
Answer: Back surface toric is better for more cylindrical corneas.
Card 8
Question: How does lens diameter affect toric lens stability?
Answer: Larger diameter lenses are more stable and recommended for more toric corneas.
Card 9
Question: When selecting a trial soft toric lens, which two parameters are essential to choose?
Answer: Base curve (BC) and diameter.
Card 10
Question: Which base curve ranges correspond to flat, medium, and steep trial lenses?
Answer: Flat: 8.9–9.0 (diameters 14.0–15.0); Medium: 8.6–8.7; Steep: 8.3–8.4.
