Welcome to the Eye Center Dietikon

Our practice is in the Heart of Dietikon. Doctor Gigers former praxis was taken over by doctor Ciechanowski in 2019. Both linked years of experience and innovation to give you high-quality eye control in all specialties, advice, explanations, surgical care, and answers to your very own questions.

In 2018 we expanded our team with doctor Christian Böni, since 2019 doctor Sonja Frimmel and since 2020 doctor Jennifer Robinson and doctor Hommayda, since 2022 doctor Grandjean is part of our team as well.

We care about a constant and professional environment in which we take our time for your concerns and questions.

Our exceptional network enables your optimal treatments: emergencies, surgeries, cataract, glaucoma, macula degeneration and therapy, uveitis, cornea, lid surgery and all ophthalmological areas.

We accept new patients currently and are looking forward to welcome you.
