Are you an Optometry Student?


1) Which zone is used to modify your central clearance?



2) When should you use the CS Prolate diagnostic lens? (in fitting guide)



3) The LITe system is a new enhanced curve compensation where lens weight can be transferred resulting in a smoother transition into the landing zone creating…



4) If you have a diagnostic lens with 650um clearance pre-setting, what should you do?



5) The Custom Stable is available in only the 15.8 diameter

6) How many microns per step does the LITe Zone affect over the limbus?



7) Where do you measure the rotation of the flat meridian SLZ from?



8) What sagittal depth lens should you choose in the 15.8 diameter CS Oblate design if your flat k is 41.00?



9) What is the ideal post-setting central clearance?



10) What is the ideal post settling clearance over the limbus?



11) What adjustment in the SLZ would you make to alleviate blanching or impingement on the sclera?


12) When do you perform the over refraction?



13) What is the minimum settling time for post-settle evaluation?



14) If you have diagnostic lens with less that 100µm clearance pre-settling, what should you do?



15) When should you use the CS Oblate diagnostic lens? (in fitting guide)



16) Which sagittal depth lens should you choose when fitting the 15.8 diameter CS Prolate design if you flat K is 50.00?



17) What meridian do the laser ‘0’ marks on the lens indicate?



18) If you have an over-refraction of -1.00 -1.00 x150 and the flat meridian laser marks are rotated 30° left relative to the 0/180 meridian on the eye, what would the axis be in the contact lens order?



19) How many microns per step does the SLZ adjust?



20) Which zones can be altered quadrant specifically?
