Highly recommend Dr Hartzell - Very happy I can see again out of my right eye he did yag laser on it. Dr Hartzel is the best in the state of PA . I highly recommend him. My son drove me there it took us a little over 3 hours to go there one way . Dr. Hartzel is the only one I trust so glad my sister recommended him to me and on the plus side I got to go home for a short visit to see my sister and brother in law. Thank you Dr Hartzel More

I just had my second eye cataract removed today. I wanted to let people know about my experience. the Surgery Center experience was A+ from check in to discharge both times. The staff was up beat, cheerful and worked as a well oiled team. It ran like clockwork. At no time did I feel stressed or neglected. My outcomes were as I had hoped. Great experience! Kudos to Dr Hartzell and his entire staff. Rick B More

I just can't express how nice it is to go to an office where everybody is friendly. Everybody smiles. Everybody understands and explains things in a way I can understand. It's just a joy to go there. Everybody smiles. Everybody greets you. Everybody makes you laugh. I love how the office is always happy, smiling, and having fun. The girls down there at the surgery center, they treat you like a person. They explain thing really well. The continually ask which eye, and your date of birth, and I don't care if I have to give it 500 times, it keeps me safe! Everyone is so great! They're always checking on you, asking if you need anything, and if you're okay. And my vision, I couldn't be happier! I can see 500% better! It's a win-win! More

I had cataract surgery which was performed by Dr. Hartzell. This was my final appointment to check the outcome of my procedure. This appointment was with Dr. Bonner. I would highly recommend The Eye Center. Very professional but also personable and caring. Dr. Bonner takes his time when he examines my eyes. I think he enjoys his work. My vision is improved to the point that I only need glasses for reading. More

Very grateful for Dr Ou and all of the wonderful staff who helped me during my cataract surgery. Dr Ou was very reassuring and thoughtful. I was so very frightened to have the surgery and now I’m so relieved and happy I did. They all did a wonderful job and my eyesight is so very much better. Highly recommend Dr Ou and their services More

Staff is professional and friendly. My visits and my cataract surgery went wonderfully. Dr Oh was very nice. I opted for just the basic surgery & now have 20/25 vision.They even accommodated me in a polite and professional manner when I was late for one of my appointments. There is a very short wait time. Their optic Center replaced my lenses. They told me an hour and they were done in an hour. I don't know about their other Lewisburg office in downtown Lewisburg as I've never gone there. But the Mifflinburg office is also great. More

I have been going to Dr. Bonner for over ten years. He does an amazing job at doing my eye exams! I also met with Dr. Hartzel about cataract surgery. I feel very confident he will perform my surgery with the utmost precision! I look forward to having improved vision. Thank you! More

I recently had cataract surgery done by Dr. Hartzell . I worried about the procedure and how it would affect my eye sight. Turned out Dr. Hartzell did an excellent job and now I only need glasses to read. I no longer have to wear my Rx. glasses after so many years. The staff that he has at both Allenwood and Williamsport are by far the nicest medical staff I ever had, in particular Lydia. My wife and I both had surgery and Lydia made everything so easy for us. We owe her a special thank-you for all her hard work and compassion she showed us. More

Dr. Hartzell is a miracle worker as far as I'm concerned! In just 2 years my eye sight had gotten extremely bad. I couldn't read anything without glasses. I wanted lasik surgery to eliminate glasses and correct my bad vision. My night vision was also terrible, it was like everyone had their high beams on. After my eye exam I found out I had cataracts. I never expected that! I was very scared about surgery. Every one there was so kind and professional. Dr. Hartzell removed the cataracts and my sight is unbelievable!!! I actually read my fortune cookie at PF Changs and amazed my family. I would encourage anyone thinking eye surgery to call the Eye Center and ask for Dr. Hartzell! More

Having cataracts in both of my eyes had affected my vision over time so much that it was hard to do anything in my daily life. It was also getting very bad driving at night from all the bright lights affecting my vision even more going to and from work. A friend had recommended this eye center so we called and made an appointment and met with Dr. Hartzell. He explained what was going on with my eyes and we began preparations for my surgery. The entire staff was very helpful through the whole process and made things go smoothly. Both surgeries went very well and my sight had improved so much just after 24 hours and kept getting better! Thank you to the great staff for being so helpful and special thanks to Dr. Hartzell for removing my clouded vision and bringing back the wonderful colors and sight back into my life! I can now see very clearly with no issues!Thank you,Iba C. More

I have absolutely no complaints about the treatments and the office visits with Dr. Hartzell. I have always been treated very well and very professionally. The cataract surgery went great, and Dr. Hartzell reviewed everything very thoroughly. I'm very happy with the treatment I received at the Eye Center of Central PA. I would recommend him to anyone.

When I arrived at the Eye Center in Lewisburg, I received a thorough exam and then met with Dr. Hartzell. At that time, I had uncorrected vision of 20/400 (that's legally blind) with cataracts that further diminished my vision. Due to three prior retina tears, Dr. Hartzell outlined what he thought would be the safest plan for me. I met with several technicians after that who went over in detail exactly every step in a three month program - and I received a book with information and phone numbers and a precise schedule. Through the measurements, left and right eye surgeries and weekly follow up appointments, I have been met with helpful and courteous people who exhibited the highest level of caring and professionalism. As I type this review, I don't know where my glasses are - my last test had my uncorrected vision at 20/15. I can look at a flower and see individual petals and vivid colors. I can look at my dog and see details in his face I've never seen before. How important is your vision? At the Eye Center, they are giving people sight - it's not like rating a coffee shop. These few paragraphs cannot express how grateful I am. More

When I came to the Eye Center of Central PA in 2016, it was a scary situation. I am a graphic artist by trade, so I need my eyes to earn a living. Both of my eyes were failing due to very aggressive cataracts... My vision turned so poor, so quickly that I could no longer drive, read a magazine or use a computer! Even something as simple as watching TV had become nearly impossible. My entire world was a blur, like looking through Saran Wrap. Dr. Hartzell and his entire staff were very assuring, comforting and confident their procedures would help me. Every step of the way they were efficient, organized and completely professional. Their cheerful demeanor before and during my surgeries, and at every follow-up appointment since, has proven I made the right choice for my eye care.The results? For the first time in 50 years, I no longer need glasses! Waking up each day with nearly perfect vision (20/25) is a true blessing in every way. My wife and I thank Dr. Hartzell, his nurses and staff for all their compassionate assistance and care. — James & Lori Wittlich More
