Here is another high quality (4744x2812) picture of one of these.

Here is what this eye looked like before.

Per here:

> (A) [The image provided here] Preoperative appearance of a 42-year-old woman with a chronic descemetocele in an anesthetic cornea from trigeminal nerve damage following neurosurgery. Prior attempts at ocular surface reconstruction with amniotic membrane had been unsuccessful. Preoperative vision was 20/200.

> (B) [The image OP provided] Postoperative appearance 1 week following type I Boston KPro, cataract removal and intraocular lens placement. Uncorrected vision was 20/20. The patient is now more than 2 years after the KPro placement with maintenance of excellent vision and without complications.
