Salzmann Nodular Degeneration
Poor eyesight: on the one hand, the nodes lead to a reduction in the transparency of the cornea (Figure: top left). In other words, the window to the outside world becomes cloudy. On the other hand, the nodules lead to a distortion of the entire cornea, as evidenced by the green-blue color in the corneal topography (Figure: top right). This results in an irregular astigmatism with poor eyesight.
Surgical treatment: Salzmann nodes can be surgically removed under the surgical microscope. However, they can reappear after 8-10 years. A second or even third distance is possible.
Improved eyesight after removal of the knots: Approximately 6 months after the operation, we will assess whether the contraction of the cornea has decreased. Why only after 6 months? Because the cornea is very slow in its response. If after 6 months there is still an irregular corneal curvature, then we can improve the cornea with the excimer laser (wavefront-guided transPRK).
