2467: Why am I getting corneal edema?

Time for our large, worldwide group of tens of thousands of ophthalmologists to help out a colleague. This anonymous surgeon is about 3 years after completion of residency/fellowship training and has done another 1000 cataract surgeries. You can see from the video that the surgical skill and technique are both very good.

These are the settings that our anonymous surgeon is using. Seems pretty reasonable.
What if we reduce the surgeon’s 80% duty cycle to 40% and left the other phaco power parameters the same? This would cut the ultrasonic energy delivery in half without much change in surgeon feel or efficiency.

But this surgeon is perplexed because on post-op day 1 many of these routine cataract patients have corneal edema. Watch the video carefully and then comment below giving your advice to improve the case and reduce the incidence of post-op corneal edema after routine cataract surgery. Thank you in advance for your help!
