I failed the exam a few months ago and am gearing up to take it again in September. I have since found your videos and feel so much more prepared than I was the first time. Thank you very much for sharing this knowledge and being clear and concise in your videos. You are doing a great job for all of us. Keep it up. Also nice shirt, I got a Fender strat not too long ago and it plays beautifully even though it does take me away from studying sometimes! Take care.
Wanted to let you know I passed my NCLE today. Your videos made such a huge difference in my understanding of the material and I just wanted to thank you.
Thanks so much for going through this and drawing the picture! I have added drawing the same picture while I work through my examples and the concept finally “clicked”! 🥳🥳🥳
This is helping me. I failed the test 2 times because I couldn’t really understand the SAM/ FAP. Thank you so much. I have a test coming up and I need to pass it this time. Thank you for teaching us
Hi Sam, in the last problem you go over, I got lost as to why the cylinder (- 0.75) and 180 axis get canceled out. I know you indicate we'd go with a gas perm, but I didn't understand the reason why.
Hey! I can’t believe you made me watch myself 🤮 lol You definitely COULD fit a soft lens for this patient. For this example I am assuming that your only options are RGP lenses. Mainly it’s focused on determining the power of a RGP lens. On the test you won’t encounter an appropriate soft lens answer and an appropriate RGP lens answer. I talk fast over the point but I say something like “assume our answers are all RGP lenses.” So GREAT QUESTION - I’m just only focusing on GP though!
I have another question. Sorry! So do you always fit rigid lenses with the flattest k? So if there is a question where you have to calculate the power for the lens and say it says k readings are 42/44@90 and rx is -1.00 -2.00 180 and they say calculate the power for bc 8.8. How would I solve this? Would I first calculate the new k and then figure out how much flatter or steeper it is then the flattest k and go from there? Maybe I’m over thinking this. 🙈
That is a really odd question… Watch the video “Base Curve Long Division.” 42 is the flattest K 337.5 / 42 = 8.035 8.8 is ~ 38K diopters That is 4 diopters flatter than the flattest k FAP What is your source for this question? It’s really odd… If they are talking about a soft toric it may be a trick question. Your logic is correct, that you posed In your question, though!
These are not more difficult. You fit the lens the exact same way you would if you were not considering SAM / FAP and THEN you just consider the sphere power as you either add or subtract based upon whether the lens is fit flatter or steeper than K Hope that makes sense 🥴
In my book i have RX +3.75 +0.50x90 Ks- 46.75/47.25 VD 8MM when I do it im either minus 0.25 or plus 0.25 /0.75 the answer in the book says ON K is +4.50 STEEPER is +4.00 and FLATTER is +5.00---- I transposed+VD (shouldn't we always?) and its not coming out to the answers in the book. I was able to figure out other questions but this one is hanging me up and I dont know what im doing wrong. Can you please help me see my error?!
Ok so let’s look at this: +3.75 +0.50 x 090 First step is to transpose: +4.25 -0.50 x 180 You always work in MINUS CYLINDER Get rid of the astigmatism component in the Rx for GP/scleral lenses because it’s insignificant and can be cared for by the lens (masked). So, we are dealing with a +4.25 sphere Rx BEFORE compensating for vertex distance. ALL CONTACT LENSES THAT ARE VERTEX DISTANCED BECOME MORE PLUS/LESS MINUS WHEN GOING FROM REFRACTED VD TO A CONTACT LENS Rx. That is why we are adding +0.25 to the +4.25 minus cyl Rx for ON K = +4.50 After that just remember SAM/FAP Steeper add minus and flatter add plus Please let me know if I his helps 😊
Thank you so much Sam for your videos, you make it so easy to understand.
So glad to hear! That was the purpose 👉🏻👁

Thank you for the encouraging feedback! Yes, my main guitar is a telecaster and I love it. You’ve got this 👍🏼

That’s fantastic, Jeff!!! Thanks for the update. Very glad the videos were helpful 😊

Great to hear. Glad you are able to benefit from these lessons 😊
Thank you for taking the time to create this material. It is immensely helpful.
You are so welcome! Thank you for the kind comment 😃
Thanks for all the help going to take the ncle in September
You have plenty of time to study up and crush that test! 💪
I appreciate you watching and commenting.
I really appreciate these videos! Testing in a month and feel like I understand so much more with your explanations! Thanks so much!
I appreciate you watching! Keep us posted!

Hi, Sophia. Thank you for the encouraging note. Third time is the charm 👊🏼 💪
Thank you
Very helpful! Thanks so much!!
I appreciate you watching!
Thank you!
Glad that you find the videos helpful!
Thanks alot
You’re so welcome! Hope the videos are helpful 👁

That is a really odd question…
Watch the video “Base Curve Long Division.”
42 is the flattest K
337.5 / 42 = 8.035
8.8 is ~ 38K diopters
That is 4 diopters flatter than the flattest k
FAP
What is your source for this question? It’s really odd… If they are talking about a soft toric it may be a trick question.
Your logic is correct, that you posed In your question, though!
What happpens when there is lenticular astigmatism or residual? How do you do these types of problems
These are not more difficult. You fit the lens the exact same way you would if you were not considering SAM / FAP and THEN you just consider the sphere power as you either add or subtract based upon whether the lens is fit flatter or steeper than K
Hope that makes sense 🥴

Thank you. Vertex distance has been the hardest for me. UGH! Tomorrow is my NCLE exam. You are an amazing teacher@@nclecontactlenstraining
@@melinda5151 you’ve got this 💪🏼
Let us know when you pass ☺️
