You are at a beach day with friends and realize that your myopic friend has been swimming in the ocean in their soft contact lenses. Which of the following are TRUE? (SELECT ALL THAT APPLY)
Soft contact lenses are highly recommended for patients looking for optical correction while swimming
Soft lenses tend to tighten on the eye when worn in the ocean
Disposing of contact lenses after water exposure is recommended
Disinfecting the lens after wear will eliminate all micro-organisms that could lead to infection after swimming in the water
Which of the following lens modalities do not present with deposits? Assume that the patient is compliant with recommended care routines and replacement schedules.
Scleral lens
Bitoric Corneal GP
Monthly soft toric
Daily soft sphere
A patient with Fuch’s dystrophy presents to the clinic. Her IOP is stable. What changes occurred to her swelling pressure (SP) and imbibition pressure (IP) that resulted in corneal edema in this case?
SP increased, IP increased
SP increased, IP decreased
SP decreased, IP increased
SP decreased, IP decreased

You successfully assess your patient's scleral lens fit and measure the central clearance of the lens to be 0.5:1.
If the center thickness of the lens is 450 microns (0.45 mm), what is the central clearance of the lens in microns?
(a)
Your patient with aphakia is presenting for his contact lens follow up after wearing his scleral contact lens for four hours. You successfully assess the settled fit without fluorescein. When the lens is removed, you observe signs of hypoxia. Which of the following changes could be considered to improve this ocular health complication?
Increase central clearance
Decrease lens thickness
Improve Dk of lens material
Educate patient to decrease wear time
Your patient says they see well with their contact lenses but are experiencing headaches at the end of the day. You collect the following clinical data from the right eye:
CL Rx: -3.25 DS (20/15)
SCOR: +0.50 DS (20/15)
Current SpecRx (2 years old): -3.50 DS (20/15)
Based on this information alone, what do you expect their manifest refraction to be this year in the right eye?
-3.50 DS
-3.25 DS
-3.00 DS
-2.75 DS
Your patient presents for a new contact lens fitting. You decide you want to fit her in a soft toric contact lens. You refract her and get the following data:
MRx: -4.50 -1.25 x 065 (20/15 DVA)
Based on the above data, what is the most appropriate trial lens power to pull from the trial lens room for her today?
-4.50 -1.25 x 070
-4.50 -0.75 x 070
-4.25 - 0.75 x 070
-4.25 -1.25 x 070
