In this video, we’re using an SOS basic phaco eye to practice creating a corneal incision and our capsulorhexis technique.
Here we’re using a three-step corneal incision. Just dipping the blade down towards the lens. That’s the last bit of that maneuver. And here, a single paracentesis, using the same blade.

I’m placing a little mark here, just on the sclera, so it’s easier to find the side port.
And a second side port entry here, on the nasal side.
Just going to fill the eye up with viscoelastic. And what we tend to do is just ask the theater team to keep the viscoelastic from theater that morning. There’s usually half syringe left after most cases and we use this for our simulation.
So having achieved a good fill, we’re going in with the capsulorhexis forceps. And my preferred technique is to initiate a tear with the capsulorrhexis forceps, dragging down centrally towards the incision, picking up the edge of the flap, and then starting to tear the capsule round in a counterclockwise direction.
Our trainees will have completed their EyeSi training modules, and many of them will have performed multiple capsulorhexes on the EyeSi. So this is an opportunity for them to put that into practice – the technique they have learned, using the EyeSi. Again, you can use a cystotome, just as easily as you can use the capsulorhexis forceps. And the same principles apply to the EyeSi training, which is just leading that capsule round, folding the capsule remnants over on themselves, so they don’t get in your way, and completing a nice circular rhexis.
And finally, just removing the capsule remnants.
This is also a basic cataract eye, but has a hard nucleus, so opposed to the softer gel nucleus. Just as in real life, sometimes the capsule with the harder nuclei is a little bit more adherent to the underlying lens. It can be a little bit difficult just to get that tear going.
Just opening up the initial groove there. Unlike the advanced phaco eyes, which the posterior chamber we cannot bury the pressure behind the lens here, because they’re hemispherical eyes, and so you cannot simulate the capsulorhexis tearing out due to raised intravitreal pressure, but nevertheless, if the trainee takes the capsule too close towards the iris, it will still tear out. And again, it just helps consolidate what they’ve learned on the EyeSi, before progressing to live surgery.
Finally, just leading the rhexis round to complete 360-degree tear.
