Hey y'all!

I am trying to decide between the Welch Allyn 125 and the Heine 500. My question is about the Welch Allyn - does it have the three filters built into it (red-free, cobalt blue and yellow) or do you have to attach them seperate? They have the older Welch Allyn's in pre clinic (I think!) and I can't rememeber seeing the 3 different filters. Alos any advice on hand held lenses would be greatly appreciated🙂


Thanks!

I cannot think of any situations where I have been in dire need of the filters on my BIO(I have a Heine Omega 180). In fact, more often than not, I prefer to use one of our spec mounts we have around the office in lieu of my bulky headmounted BIO. I just pop out the lenses in the spec frame and away I go.

As for BIO lenses, my favorite is the 25D lens. I learned this from a retina guy I used to work with. It is a great balance between mag and field of view. My next favorite is a 28D lens. I have found that since I dilate every routine patient with pyramyd I can get out quite a ways with a 28 even if I only have a 6-7mm pupil. My next choice would be the Volk 2.2 and lastly the 20D. Just my opinion, but I have tried them all. I would suggest purchasing a 150-160 degree contact fundus lens as well. They are expensive($500 or so) but they are great when you have a patient that is not cooperating with scleral depression or a three mirror lens when you want peripheral views. Let others say what they will, but I use my BIO 12-15 times per day and these have proven effective tools for me.
