Does Anybody Know the Outside Diameter of the Losmandy 21# Counterweight?

Posted By Chuck Burton

I called Losmandy today to get that information, but even THEY are out of stock and could not provide that info.! If you have one of of those, I'd appreciate the information.  Thanks!

Cataract surgery

Posted By Chuck Burton

Hello Robert:

That's an excellent question. I had both myopia and astigmatism issues and wore bifocal lenses in my glasses. As a "cataract surgery survivor," (2012) who is also an astronomy enthusiast, cataract surgery was a big deal for me. Fortunately, I had a surgeon who was very familiar with this issue. Some of these may not be applicable to your condition. You have a range of options with IOLs. Straight plastic replacement with no myopic or astigmatism correction, or IOLs with correction for one or both of those conditions, or, a sort of bifocal option, or a "soft" lens option they had just come out with at the time, that would eliminate the need for bifocals, since the eye itself would be able to focus this lens near and far. The surgeon told me that the "bi-focal" and "soft lens" options would affect my ability to focus star images across a wide field. He recommended that I stick with the hard plastic lenses, with or without the correction built in.  That's what I ended up doing.  Post surgery, I was able to ditch my glasses entirely. The clarity and pinpoint star images were breathtaking in their magnificent contrast. It was like being reborn! This cataract stuff sneaks up on you over the years and you just don't realize how bad things have gotten.

That was 10 years ago. The third year in, my astigmatism began to return. I had to go back to wearing glasses to correct it. But I still don't need correction for myopia - just the astigmatism, so the lenses in my glasses are very thin.

Today, you probably have options that weren't available 10 years ago.  But here are a few ideas to discuss with you doc.  Good luck!
