    https://www.reviewofophthalmology.co...taract-surgery


    Here's an excerpt:

    During clear corneal cataract surgery, which now accounts for 73 percent of cataract surgery according to this year's trends survey by the American Society of Cataract and Refractive Surgery, a large portion of the corneal nerves are cut. With a typical cataract surgery, the primary incision may be about 3.0 mm in width, and the paracentesis about 1.0 mm in width, giving a total arc length of 4.0 mm of full-thickness corneal incisions. If we add to this the additional incisions for astigmatic correction, such as limbal relaxing incisions, or the three-incision technique of bimanual cataract surgery advocated by some surgeons, the cutting of corneal nerves is even more severe.

    The corneal nerves are important in the self-regulation of tears since they provide the sensation in the feedback loop that signals tear production. When we block or decrease the function of these nerves, we can significantly limit the eye's ability to create a proper tear film, which can lead to decreased vision and symptomatic patients.



    ETA: The good news is that the nerves heal and the Dry Eye gets better. Thank goodness.

    Good to hear from you, @Jeanlouise !

    My daughter had a balloon angioplasty of her tear ducts performed by her ophthalmologist. Kind of a Rotor Rooter for the tear ducts.

    Hey there Rock!

    I've never heard of that treatment but I'm not all that familiar with eye stuff, although I'm learning a lot more since I had this bad experience.

    I hope it helped her.

    Fixed her right up!

    Balloon catheter dilation

    Your doctor guides a very thin catheter through the blockage in the tear duct, starting from the nose. They then inflate a tiny balloon several times to push away the blockage and open up the duct system. This requires general anesthesia.

    I need general anesthesia just reading that.


    I'm so glad to hear that she's all better!

    I welded up some cattle racks for a farm truck not long ago.
