Title: Intra ocular lenses
Post by: kbgala on October 03, 2007, 04:24:32 am
I wd like to see ray diagrams for an eye having a posterior chamber intraocular lens and another one with an anterior chamber intraocular lens.

Any help wd be appreciated.

I am not sure is the following flash is what you need. However, It was created with Chinese descriptions without ray diagram. You can click one of the pictures at the right side. (Happy face is the normal eye, the other two un-happy faces are near-sight and far sight person.) You can then drag the butterfly and watch where the image was formed and how it might look like from that person's view. Click the lens to see what will happen.

Thank you for your reply.

But as you had thght , these are not what I wanted.

These diagrams are for people who are myopes or hypermetropes who have their own lens in the eye.

What I need is ray diagrams for people who have had cataract surgery with implants in the eye in the anterior chamber ( ACIOL ) or in the normal lens position ( PCIOL ).

BTW, I am an Indian working in UK. I have really found your website amazing.

It will be very helpful if you can give me the raydiagrams tht I want. Thank you again for the quick response.

I do not have enough information about your situation. But you can create the ray diagrams by yourself.
What you need is just the snell's law. n1 sin c1=n2 sin c2
