Salzmann Nodular Degeneration of the cornea

A Salzmann degeneration is a deposition of tissue (collagen) on the superficial cornea. The figure shows a black-and-white optical coherence tomography (OCT) with whitish support in the lower part.

This degeneration is usually caused by chronic irritation and grows slowly over years. Even wearing contact lenses for decades can lead to Salzmann degeneration.

Salzmann signs

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).

My left eye had to be operated on because of a cataract. As I had an Artiflex lens implanted a few years ago, it had to... be removed first before a modern lens could be implanted to correct the cataract. Prof. Hafezi treated me in an very competent and friendly manner. I am very happy with the result.read more

At the moment, 3 months have passed since the moment I made laser vision correction in this clinic. and I can say that... I am happy that I chose this particular clinic and Prof. F. Hafezi. The entire staff of the clinic is very friendly, treats patients with sympathy and patience if they are nervous before surgery (my big gratitude to Aida Alili for all support and patience). The doctor Hafezi and other doctors of the clinic are very professional and ready to explain to you as many times as you need. I can only recommend!read more
