A photograph that was used for the cover of EDN magazine was posted to the Tek wiki site today. The photograph was published in November 1982 to support the introduction of the 7D20 and to reinforce the modularity of 7000 series. I apologize for the color balance. The photograph was badly faded to orange. I made a color correction but with my yellow cataract vision, I over emphasized the blue.

Thank you Kurt R. for posting the photograph.

Very nice piece of tektronix history. Thanks to both of you.

Greetings,

I’m a little off topic and not certain if I intend this message for Clark F or Kurt R.

Perhaps my comments may be a value to others.

I was inspired to comment based on reference to “yellow cataract vision”.

I suffered with advancing cataracts for far too long. I kept telling myself that it really wasn’t that bad yet.

Finally, my charming child bride, who had become very uncomfortable riding with me when I was driving convinced me to have the surgeries.

From my perspective I was amazed how easy it was. I showed up, they gave me some “happy juice” and when I woke up the view out of the eye they had just repaired was amazing!

I had actually forgotten what white looked like. Everything had slowly turned yellow, and I had no idea how extreme the color shift was. A few months later I had the other eye surgery with equal success.

Technology has come a long way. When I was a kid in the 1950’s and 1960’s the older people I knew who had had cataract surgery wore truly Coke bottle bottom thick glasses. That’s not the case any longer.

There are many different choices of IOL (Inner Ocular Lenses). The main options include: monofocal lenses (standard choice), toric lenses (correct astigmatism), multifocal lenses (for multiple vision distances), extended depth of focus (EDOF) lenses (improved intermediate vision), and light-adjustable lenses (post-surgery customization); with the best option depending on your individual vision needs and whether you want to minimize reliance on glasses after surgery.

Since I need flip-down magnifiers for small work anyway I chose a standard monofocal distance vision lens.

OK - forgive me for typing a lot of words. I just wanted to share that in my opinion cataract surgery is a wonderful procedure that made my life so much better. The bonus is that my wife is once again comfortable when I’m driving.

If any of you are putting off cataract surgery for whatever reason - and I had mine - don’t wait. Get your vision back!

Regards,

Ken

I am glad to see this response. I am due for implants soon so its certainly of value to me. Missed my appointment due to flu but due for exam by surgeon in a couple of weeks. I have fairly advanced cataracts. Pictures of the inside of my eyes show them plainly. I was fooling myself they were not that bad but now realize just how bad my vision has become. I know lots of people who have had cataract surgery and lens implants, all seem to be very happy with them. I will have fixed distance vision installed. I've had experience with bifocals and trifocals and hated them. Don't mind reading glasses at all. Exam I had showed that beside the cataracts my eyes are healthy.

I wonder if that Lego 7K scope still exists somewhere.

I also had some years ago my right eye done. It took me about three hours in the clinic all in all.
Perfect result. My left eye is only slightly yellowish like the right was but the color temperature is hardly noticeable. What was bad essentially on the right was much dazzling. My right plastic lens is much better than the original one.
I concur that if one need it, do not hesitate to have cataract surgery.
