Lamellar Keratoplasty (LK)

Most corneal transplants performed in the U.S. involve replacing the entire thickness of the diseased cornea with a healthy donor cornea (called penetrating keratoplasty or PK). In partial-thickness corneal transplants (LK), only the anterior (surface) layers of the cornea are removed. The donor cornea is then attached to the host corneal bed, containing only posterior (deeper) layers. LK is less risky, but tends to result in somewhat inferior vision vs. PK and cannot be performed if the disease process (e.g. scar) involves the deeper layers of the cornea.

Otimag, for example, has a condition called keratoconus, in which the cornea has a cone shape, which is often treated successfully at first with contact lenses. However, as it worsens, many patients require surgery (the one shown in video is but one example).

Remember, there are lots of different disorders of the cornea, and each one is treated in a different way.

This is my video; I wanted to address misconceptions in your comments. First, there is NO PAIN because anesthesia is used (not general--put to sleep; instead, local--using numbing drops & a shot around eye). Second, this procedure is completely different from LASIK/refractive surgery (reshaping a healthy cornea to eliminate glasses/contacts). In video, the cornea (like a cameras lens) is damaged, preventing/distorting light entering eye. Oversimplified. Please ask ?s if unclear.

God Bless.

Oh, thats all? Honestly thought it would be alot worse, but Im sure it hurt like hell for the patient when they woke up oAo

I just had an eye surgery on my right eye and got intacs rings in my cornea now, but obviously my keratoconus condition was really bad that the intacs didn't help at all. I guess I'm facing this same surgery soon and it sure doesn't look nice :(

mini spatula........lol,also nasty

[sk8rdude140]

These types of eye surgeries are done under anesthetics so the patient is asleep
