模拟手术:超声乳化——碎核块移除

模拟眼科手术基础型白内障模型眼虽然不包含任何皮质物质,但一旦晶状体核被劈分为四个象限,受训者即可练习使用辅助器械将这些碎核块推向超声乳化探头,并将其移除,同时避免损伤囊袋连续环形撕囊的边缘。

除了Cyber​​sight 的图书馆以外,您还可以在这里找到各种模拟手术视频,展示了使用不同类型的模拟技术来进行各种眼科手术的技巧。

In this video, we’re illustrating how we use an SOS basic cataract eye to practice segment removal. Once again, just consolidating the skills that trainees would have learned with the EyeSi modules.

These skills are really manipulation of the quadrants within the anterior chamber, making sure the phaco probe does not pass too deeply or too close to the capsulorhexis margins. Using the second instrument efficiently for manipulating the quadrants towards the phaco handpiece itself, and not chasing the segments of nucleus towards the edge of the rhexis.

The nuclear fragments tend to be slightly lighter, less dense than live lens would be, so they tend to float slightly more anteriorly in the anterior chamber than normal nuclear fragments.

But the principles of manipulating the quadrants using the second instrument and coordinating use of the phaco tip and the second instrument are all invaluable skills to learn before the trainees progress towards live surgery.

I tend to use slightly higher vacuums to remove the segments than you would normally do. Of course, with the basic phaco eyes, there’s no posterior capsule to be sucked up into the port. So, the only jeopardy is getting too close to the anterior capsule and causing an anterior capsular tear.

In the last couple of seconds of the clip, you just see the little small remnants of the lens, which, in real live surgery, can be a little bit tricky to maneuver and to remove. And the last one, just disappearing now.
