Improving vision after corneal scars

Corneal scars can often result from an accident or an infection. Corneal infections can be caused not only by bacteria or fungi, but also viruses or parasites. These pathogens migrate into the transparent cornea and cause all of these problems. Although the pathogens can often be eliminated, the damage in the cornea has already been made, and the scar, depending on its location, can severely impair people’s visual acuity. In fact, visual impairment due to corneal scarring is one of the major causes of blindness worldwide.

Cloudy or blurred vision?

Corneal scars can do two things:

  • Cloudy scars stop people from being able to perceive the world around them clearly.
  • However, the scar tissue can also pull on the cornea, changing its shape, and triggering irregular astigmatism, significantly reducing visual acuity.

Laser treatment of the scar

We have a number of ways to reduce the effects of corneal scarring. Our motto is that it is always best to maintain your own cornea, and that corneal transplantation is only the option of last resort. With that in mind, if the excimer laser can be used to improve the cornea to the extent that good vision is possible, then this is always the best choice. Lasering is often carried out in two stages: in a first step, what’s called phototherapeutic keratectomy (PTK) is performed, which is primarily intended to reduce the opaqueness of the scarred part of the cornea. If a part of the scar is then removed, then the cornea will relax over the next few months, reducing the irregular corneal curvature over the next 4–6 months

Operated by us

A 19-year-old patient who showed a corneal scar after fungal infection. The scar caused both a cloudiness and a very irregular cornea. The best corrected visual acuity was 40%. After reconstructive laser surgery, the vision was 80% and the cornea was much more symmetrical.

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
