🤔Hit Me UP__ Inbox Open 24/7 – 365 …...!!!! 🤔 Chat with us here : 🤔 Hybridgrades101@gmail.com B. Aphakic C. Bitoric D. Keratoconus - =Answer>> The answer is A. A lens is truncated by removing a segment of the lower edge of a contact lens. This creates a straight edge that interacts with the lower lid and aids in lens positioning. Of the lens designs listed in the question, the only one that requires precise positioning of its optical portions is a translating bifocal lens.
- The mass of an aphakic rigid gas permeable contact lens can be reduced by making the lens design: A. Spherical B. Lenticular C. Tricurve D. Aspheric - =Answer>> The answer is B. A lenticular or myoflange design will decrease the mass of an aphakic lens as well as increase the edge profile, which allows it to interact more with the upper lid and aid in positioning of the lens.

🤔Hit Me UP__ Inbox Open 24/7 – 365 …...!!!! 🤔 Chat with us here : 🤔 Hybridgrades101@gmail.com A. Aspheric peripheral curves B. A myoflange C. A higher Dk material D. A hyperflange - =Answer>> The answer is D. A hyperflange will decrease edge thickness as well as lens awareness. Aspheric peripheral curves change the posterior design of the lens but do not reduce edge thickness. A higher Dk material will not change the overall lens edge thickness. A myoflange will actually add thickness to the lens edge and is used for high plus lenses not high minus lenses.
- To add minus power to a rigid contact lens with a rotating modifying spindle, one would: A. Polish the posterior surface of the rigid lens B. Polish the mid peripheral anterior surface C. Polish the central anterior surface D. Polish the peripheral anterior surface - =Answer>> The answer is C. One would rarely polish or attempt to manipulate the central posterior surface of a rigid lens. Applying polishing pressure to the mid-peripheral and the peripheral anterior surface would add plus power. Applying polishing pressure to the central anterior surface would add minus power.

- Which lens design would provide the best visual acuity for a patient with the following information? K's 42.00@ 180/ 42.50@ Rx -6.75 +1.75 cx 90 A. Front surface toric rigid gas permeable B. Spherical rigid gas permeable C. Soft sphere D. Bitoric rigid gas permeable - =Answer>> The answer is A. The keratometer readings indicate the need for a spherical back surface, which would rule out the use of a bitoric lens. A soft spherical lens would not correct the moderate amount of refractive astigmatism that is present, nor would the spherical rigid gas permeable lens. A front surface toric RGP would best meet this patient's needs since it has a spherical back surface, but has a toric front surface which would correct the residual astigmatism.

Mixed astigmatism - =Answer>> The answer is C. Lenticular astigmatism usually exists when the amount of refractive cylinder is greater than the amount of corneal cylinder. It is assumed that the additional astigmatism originates in the crystalline lens. Ch1-1. Which layer of the cornea makes up 10% of the structure's total thickness? A. Epithelium B.

- In which of the following situations is a rigid gas permeable lens always preferred over a soft lens? A. Regular astigmatism B. Irregular astigmatism C. Aphakia D. Presbyopia - =Answer>> The answer is B. With regular astigmatism, even high degrees, a soft toric lens can work quite effectively. Presbyopic and aphakic patients can also be successfully fit with soft lenses. However, patients with irregular astigmatism will achieve their best visual acuity only with rigid gas permeable lenses since soft lenses will mold to the corneal contour and not mask the irregularity.

- In order to steepen the base curve of a rigid gas permeable lens without changing the lens to cornea relationship, you would also need to: A. Decrease the optical zone diameter B. Decrease the center thickness C. Increase the overall lens diameter D. Increase the lens power - =Answer>> The answer is A. Decreasing the optical zone diameter while steepening the base curve of a rigid gas permeable lens will allow the lens to cornea relationship to remain the same, since decreasing the optical zone diameter loosens the lens to cornea relationship and steepen- ing the base curve tightens the relationship. Increasing the overall lens diameter also tightens the fit and will only exaggerate the change made to the lens to cornea relationship. Decreasing the center thickness or increasing the lens power will have no significant effect on the relationship of the lens to the cornea.

- Which of the following modifications can be made to a rigid gas permeable lens in the office? A. Blending B. Changing the power C. Polishing the edge D. Changing the base curve - =Answer>> The answer is D. Many modifi~ations to rigid gas permeable lenses can be done in the office, saving time and improving service. Blending peripheral curves, adding minus power, adding plus power, polishing the edges, polishing the anterior and posterior surfaces, as well as reducing lens diameter are all examples of modifications that can be performed in the office.
- To achieve a lens to cornea relationship that exhibits apical clearance, the lens is designed steeper than the flattest corneal measurement. This lens will most often position: A. Centrally B. Temporally C. Superiorly D. Inferiorly - =Answer>> The answer is A. Need Writing 🤔Help? We've Got You Covered! ✍ 100% NO A I or Plagiarism Guaranteed🤔
🤔Hit Me UP__ Inbox Open 24/7 – 365 …...!!!! 🤔 Chat with us here : 🤔 Hybridgrades101@gmail.com Lenses that position temporally or inferiorly are not typically indicated and should be avoided. Lenses that position superiorly are often lenses that have been designed with the apical alignment philosophy and have been fit flatter than the flattest keratometer reading in order to achieve this alignment. Lenses that are fit with apical clearance are fit steeper than the flattest corneal measurement and often will fit intrapalpebrally or centrally.
- Which of the following are visual systems used by rigid gas permeable bifocal lenses? A. Translating and hyperopic B. Simultaneous and instantaneous C. Simultaneous and alternating D. Truncated and prism ballasted - =Answer>> The answer is C. The two visual systems utilized by rigid gas permeable bifocals are simultaneous and alternating. With simultaneous vision systems, both near and far images are received by the retina at the same time. Concentric and aspheric bifocal lens designs utilize simulta- neous vision principles. With alternating vision systems, the lens will move on the eye, delivering the focal length that is in front of the pupil as the lens translates. Segmented bifocal lens designs fall into this category. Need Writing 🤔Help? We've Got You Covered! ✍ 100% NO A I or Plagiarism Guaranteed🤔
🤔Hit Me UP__ Inbox Open 24/7 – 365 …...!!!! 🤔 Chat with us here : 🤔 Hybridgrades101@gmail.com A. 1and B. 1and C. 2and D. 2and4 - =Answer>> The answer is D. Flattening the base curve of the lens and decreasing the overall diameter will each decrease the sagittal depth of the contact lens. By combining both factors, the impact will be magnified. Steepening the base curve and increasing the overall diameter will both increase the sagittal depth.
- Dimple veil staining on the cornea is caused by: A. Poor polishing of peripheral curves B. Air bubbles trapped under a rigid lens C. Debris trapped under a rigid lens D. A cracked contact lens - =Answer>> The answer is B. Dimple veil staining is not traditional staining but is rather a pooling of fluorescein in depressions or "dimples" on the surface of the cornea. These dimples are caused by air bubbles that become trapped behind a rigid lens in an area where the distance between the lens and cornea is too great. Dimples will be found centrally if the base curve is too steep and peripherally if the base curve or peripheral curves are too flat. Need Writing 🤔Help?

- The GP multifocal design that relies on the use of a variable rate of curvature across the lens surface to achieve a change in power is known as: A. Concentric B. Translating C. Aspheric D. Truncated - =Answer>> The answer is B. The parameters listed in C and D will flatten the lens to cornea relationship. While answer A does steepen the lens' relationship, it does not take into account the change in the power that is necessary when the base curve of the lens is altered.
- To allow for proper corneal oxygenation when fitting rigid gas permeable lenses, which of the following material characteristics must be considered? A. Dk B. Dk/t C. Wetting angle D.
