我通常不会让病人带走白内障,因为手术过程会将白内障乳化成液体并吸出。这就像制作白内障汤一样,然后用真空吸出。我不会这样向病人描述,因为听起来很可怕。但是,这就是基本过程。我会用一个小切割器将白内障分解成许多小块,然后将其乳化成糊状,再吸出来。所以,通常情况下,没有什么东西可以给病人带走。唯一例外的情况是,如果白内障非常严重,致密到像钻石一样坚硬,无法用我们目前的技术将其分解成小块。我曾在住院医师培训期间见过一次这种情况。我的上级医生进行了一种特殊类型的白内障手术,这实际上是我们过去进行白内障手术的方式,我们会做一个更大的切口,这叫做囊外摘除术,我们会完整地取出白内障,而不会将其分解。现在,我们只有在晶状体非常致密以至于无法将其分解的情况下才会这样做。我曾经见过一次,上级医生完整地取出晶状体,它是黑色的,像石头一样坚硬。它可以放在你的手掌上,非常小,你可以敲击它,它很硬。在这种情况下,你可以把它给别人。但这非常罕见。你必须去一个欠发达国家,那里进行大量的白内障手术,你才能看到更多这类问题。在美国,我们通常会在白内障发展到那种程度之前就进行手术。

Chapters
The podcast discusses whether patients can keep their cataracts after surgery. Most of the time, the answer is no because the cataract is emulsified and removed as a liquid. The only exception is when the cataract is extremely hard, which requires a different surgical technique, and could theoretically be kept.
  • Cataracts are usually emulsified and removed as a liquid during surgery.
  • In rare cases, a very hard cataract can be removed intact.
  • This is more common in underdeveloped countries where cataracts are often more advanced before treatment.

Shownotes Transcript

In this episode I tackle the fascinating eye questions you've had for me. I explore the debate over castor oil for dry eye treatment, share a wild cataract surgery story involving a rock-hard lens, and answers questions about anisocoria and optic disc drusen.

Takeaways:

The Risks of Nevus of Ota: Dr. Flannery explains how this rare pigmentation condition, seen in Daniela Ruah, increases the risks of glaucoma and uveal melanoma, emphasizing the importance of regular eye exams for those affected.

Eye Rubbing Dangers: Chronic eye rubbing can lead to serious conditions like keratoconus, corneal changes, or even optic neuropathy in extreme cases. Gentle rubbing is okay, but moderation is key.

Castor Oil Debate: While castor oil is a popular folk remedy for dry eye, Dr. Flannery highlights its lack of conclusive evidence and advises patients to stick with scientifically-backed treatments like artificial tears.

Rock-Hard Cataracts: He shares a rare cataract surgery case involving a dense, diamond-like lens that had to be removed intact, highlighting the importance of early intervention for cataract treatment.

Exploring Anisocoria: Dr. Flannery breaks down common causes of uneven pupil sizes, from benign physiologic anisocoria to signs of more serious conditions like Horner’s syndrome or third nerve palsy.
