  • I opted to have the RESTOR lens for my cataract surgery. WOW!! No more glasses. It is amazing. I can read, see my computer and cellphone, drive day or night, hunt, fish - everything.
    Bernard Grosswiler on cataract surgery by Dr. Allen
  • My vision has been restored to as close to perfect as it can be and without having to be burdened with the hassle of wearing glasses.
    James Fishbaugh on cataract surgery by Dr. Zahler
  • It's very painless. Now, I don't have to wear glasses at all.
    Carol Stoneham on cataract surgery by Dr. Zahler
  • My husband and I appreciated the kind service you provided for me during my recent cataract surgery. The old saying "no pain, no gain" is wrong. I had absolutely no pain and I gained so much.

COVID-19 Update: (April 29, 2020)

At North Central Eye, we have been working diligently to maintain a safe environment for our physicians, our staff and most importantly, our patients. We have changed numerous operations to limit exposure, and you may notice some changes in the office and in our optical shop, both of which are open and ready to serve you. In addition to our efforts of meticulously cleaning each room and rotating the rooms used each day, please expect the following for your safety:

  • All patients should wear a mask while in the building.
  • Patients should check in by calling 419-668-3295 from the parking lot. Our staff will then call you to tell you when to enter the building, in order to control our ability to provide adequate social distancing. Our waiting room now has a limited number of seats spaced far apart.
  • Only the patient should come into the office. Spouses, friends, or other companions should wait in the car in order to lessen exposure.
  • In our optical shop, please do not touch the frames on display. Our optical technicians will assist you, and you can point to the frames that you would like to try on. After each session is finished, every pair of frames touched is cleaned.
  • If you have an outstanding bill, please feel free to call and we can process it over the phone with your credit card rather than in person.

Most importantly, if you have;

  • experienced any coronavirus-like symptoms; fever, cough, shortness of breath, difficulty breathing, shaking chills, loss of taste or smell, sore throat, fever, or
  • have tested positive for COVID-19, or
  • been exposed to an individual with known COVID-19, please call 419-668-3295. We would like to reschedule you to a time when you feel better and/or have been cleared by your doctor.

Finally, thank you for your patience through this challenging ordeal. Your support of us- as a small business and a group of front-line medical workers- is what makes us proud to serve our local community.
