“I look forward to helping my patients achieve their best possible vision. My goal is not only to improve patents' eyesight, but also to improve the quality of their life.”
Dr. Kersten has been a busy ophthalmic surgeon with Harvard Eye Associates since 1988. Her lifelong dedication to improving sight has led her to specialize in the laser correction of refractive (focusing) errors. Dr. Kersten performs LASIK and other refractive procedures to precisely correct near and farsightedness and astigmatism. She has successfully treated thousands of patients including many doctors, family members and even her own husband!
Her ophthalmology training was completed at Harvard Medical School (The Massachusetts Eye and Ear Infirmary). For two years (1986-1988) she volunteered her surgical skills while working in underdeveloped countries in Africa and Asia. She has continued this volunteer work by donating her time to cataract clinics in underprivileged countries. To date she has worked in 18 developing countries and has performed thousands of ocular surgeries all over the world.
Dr. Kersten received her medical school training at the University of Iowa and her internship was at the University of California at San Francisco. Dr. Kersten is a fellow of The American College of Surgery and she is board certified in ophthalmology by the American Board of Ophthalmology.
