Please expand on your comment that you use your trusty second instrument to protect against posterior capsular rupture. I was unaware that the Connor Wand was gentle enough to hold back the capsule by itself.
Best,
Alan
Tim Root: I use the straight Connor wand almost exclusively for my second instrument. I wouldn’t rely on it exclusively to hold back the capsule, as the round tip is small and could bluntly rip through the capsule with any major surges (especially if there are any scratches on the end from mishandling).
Instead, I spin the straight Connor 90 degrees, and hold it in this side position (see this drawing).
I then hover my Connor tip under my phaco tip (and under the fragment I’m removing … as in this photo). If there is a surge, or the fragment phacos out fast, the connor keeps the capsule from billowing up into my phaco tip. This position is hard to maintain with the bent Connor as you can’t spin it in your fingers.
In general, I think it best to NEVER touch the capsule with ANY instrument. I view the Connor wand as a final safety bumper … of the two instruments (Connor and Phaco Handpiece), it’s the one that is least likely to break the capsule. I was taught this safety technique during residency, and it’s saved me several times.

Sir,
I am a 2nd year student of Optometry (distance learning). Your lecture on Glaucoma, Retinoscopy and misaligned eye were very helpful. In fact Tropias and Phorias are clear now and I am doing Retinoscopy effectively now. Thanks a ton. One of my fellow senior student suggested JCC to be very effective tool for finding correct cylender and its axis, but he stays far off. I am unable to use JCC properly. Please help.
Regards
Anant
