23.2 Case 2: Remove sutures after corneal transplant surgery?
by Tobias H. Neuhann, MD
A 22-year-old white male had received a corneal transplant due to keratoconus 12 months earlier.
The first suture had already been removed. Examination with the Pentacam® revealed only a small
degree of corneal astigmatism (Figure 189), but also a peripheral hot spot (black circle). BSCVA was
20/25 after removing the first sutures. The question now was whether also to remove the remaining?
WHAT WOULD YOU RECOMMEND?
We recommended no suture removal because of the „hot spot“ temporal of the center and the low
astigmatism. The patient only wears his glasses for driving at night.
