- When verifying the posterior curves of a rigid gas permeable not all of the mires are clear in all meridians. This can occur in all but a: A. Warped lens B. Bitoric lens C. Back surface toric lens D. Front surface toric lens - =Answer>> 25. The answer is D. A front surface toric lens will show clear mires in all meridians which indicates a spherical posterior surface. Warped, bitoric and back surface toric lenses will all show unclear mires in the radiuscope indicating that the posterior surface is not spherical. In the lensometer, bitoric, back toric and front surface toric lenses will all display sphero-cylindrical readings. Only Need Writing 🤔Help?

- A translating bifocal wearer complains of blur at distance. Upon slit lamp exam, you notice that the bifocal segment bisects the pupil. In order to improve this situation, you should: A. Increase the seg height B. Decrease truncation C. Decrease prism ballast D. Decrease seg height - =Answer>> The answer is D. Decreasing the height of the bifocal segment is the only option that will drop the seg and alleviate the visual confusion caused by the segment bisecting the pupil. All of the other options will move the bifocal segment further up into the line of vision.
- Dimple veil staining is resolved by:
- Antibiotics
- Steepening the lens to cornea relationship
- Flattening the lens to cornea relationship
- Lenticulation A. 1 and 2 are correct B. 2 and 3 are correct C. 1, 2 and 4 are correct D. None of the above will resolve dimple veil staining - =Answer>> The answer is B. 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 Dimple veil staining may occur when there is either a steeper or flatter than recommended lens to cornea relationship. Air bubbles become trapped in the excessive space and create dimples on the corneal surface. Antibiotics will not affect dimple veil staining, nor will lenticulating the edges. Re-evaluating the lens to cornea relationship will identify the problem and allow the fitter to change the base curve and/ or peripheral curves to eliminate the dimples.
- Rose K, McGuire and Soper are all different types of which lens design? A. Post-refractive surgery B. Keratoconus C. Torie D. Aspheric - =Answer>> The answer is B. The Rose K, McGuire and Soper lenses are all designs specifically created for the keratoconus eye, with steeper, smaller optical zone diameters and customized peripheral curve systems to improve the fit on the unique corneal topography of a keratoconic eye.

- Which of the following can occur in patients who have thyroid disease? A. Decreased tear function B. Decreased wearing time C. Increased mucin and lipid tear components that can cause lenses to adhere D. Increased tear function The answer is D. Thyroid diseases such as hyperthyroidism, hypothyroidism and Grave's disease, often cause subtle changes in the body even before a positive diagnosis is made. This can lead to problems wearing contact lenses, such as decreased and altered tear film and decreased wearing time.
- Which of the following eye conditions may require a cosmetic painted iris contact lens? A. Aniridia or iridectomy B Iritis or rubeosis C. Iridectomy

- =Answer>> and corneal thinning are all indications of keratoconus.
- If a patient has three diopters of against the rule corneal cylinder and 2 1/ 2 diopters of refractive cylinder, the RGP lens design that will give the best vision and comfort is a: A. Bitoric rigid gas permeable lens B. Back surface toric RGP lens C. Front surface toric RGP lens D. Aspheric RGP lens The answer is A. Bitoric RGPlenses are indicated when both the corneal and refractive cylinder are greater than 2 1/ 2 diopters and are of unequal amounts. In this case, there is too much corneal astigmatism for a front surface toric lens (which has a spherical back surface and a toric front surface) and the against the rule astigmatism would probably result in decentration and rocking of any lens with a spherical posterior surface. A back surface toric lens would not work optically for this patient. While an aspheric lens may work for this patient, the h
