"Berks Eye is the best place I have ever been for eye care. I had Dr Calder remove my cataracts 1 year ago and have not had to wear glasses since they have been done. Was just in for my 1 year check and I have perfect vision. If you looking for the best eye care Berks Eye care is the place." – Ernest K.
“When I came to Dr. Calder, I couldn’t see anything. Not even the Large “E” on top of the eye chart. I saw several Doctors before doing my cataract surgery with him and no one could help me. Now I won’t see another doctor – he gave me sight! This is the greatest place – I would refer anybody here. It’s wonderful to not need glasses anymore!” – Sandra D.
“Dr. Calder did my cataract surgery.There aren’t enough people in the world like him! He is friendly and calmed me down when I was scared. The procedure changed my life. Before my vision was very bad and now everything is brighter and more pleasant.” – Phyllis K.
“I had cross eyes, my left eye would turn in and there was no way to fix it. I had cataract surgery on both eyes. It was a miracle, what happened – I’ve been wearing glasses since I’m 2 years old and I’m now 74. It was a really easy procedure, there was no pain involved, I wasn’t even uneasy one minute. It was just exciting – it was an awesome experience – Dr. Calder did the surgery and I must say he is a genuine, real, compassionate person that is really caring. I couldn’t believe it after my surgery I could see without my glasses…which to me is a miracle! It’s just awesome.” – Fay H.
“In my 75 years I have seen many doctors. I have never met anyone that has such a wonderful personality like Dr. Calder has. I am happy to be his patient. Thanks again for everything.” – Joanne S.

I have worn glasses 60 of my 65 years. Dr Calder not only made me see better, but also has the finesse to treat people like they want to be treated. A man that loves his job- from the time you check in until you check out, from staff to doctors, you are treated wonderful. – Judith H.
This is the best day ever. I van finally see everything I haven’t been able to see for years. If you are considering cataract surgery, do it! Get out of the cloud and see the sun. I am so happy with my outcome. I felt blinded for years and I can now see. I am enjoying every color there is. It was painless and easy and I wish I did it sooner. – Jodie S.

I had cataract surgery by Dr. Calder approximately 5 years ago. Now that it’s time to have the same done on my other eye there was absolutely no hesitation. The experience was smoother than he told me it would be. The entire staff from the initial registration person through to Dr. Calder are very professional and cordial. It was as pleasant as any surgery could possibly be. I wore corrective lenses for the first 60 years of my life and now I only wear “readers” at certain times. I’m looking forward to this second experience. — Rodney W.

He and the staff there did a great job and now I can see a big improvement in my vision. Thanks Berks Eye! — William S.

My optometrist detected a cataract developing on my left eye and referred me to Berks Eye Physicians and Surgeons. Dr. Calder said I could schedule surgery whenever I was ready. I wasn't in a real hurry to have an operation so I put it off. Over about a 2 year period my vision had noticeably declined so I made another appointment with Dr. Calder. No wonder my vision had gotten worse, now I developed a cataract in my right eye as well. Over a two week period both cataracts were removed and a stent was installed to reduce the pressure from glaucoma. - Edward G.
Dr. Calder removed my cataracts and I was amazed at what a difference in my vision. Great job Doctor Calder! – Bill S.
Doctor Calder is the best Doctor I have ever had. Over the course of my long life, I have had many and never had one that truly cares and wants to the very best for me. He called me, my husband and a friend I recommended several times after our surgeries. Actually, most recently about an hour before the Super Bowl, seriously what other Doc would do that? It was not a recorded call, a personal chat. He prides himself in having the best possible outcome for his patients. - Leona M.

In July 2019 when I was visiting my mother, I awoke with an eye infection in both eyes. Since my eye doctor was in New York and I preferred seeing an eye specialist rather than going to an urgent care facility, my mother called Berks Eye Physicians & Surgeons, where she is a patient. Dr. Calder said that he would see me even though I was not a patient and it was a Sunday morning when the office is not normally opened. Dr. Calder examined my eyes very thoroughly and proscribed a medication which I needed to put into my eyes 4 times a day for a week. Within a day, my eyes improved and the infection was gone by the time I finished the protocol. I was so grateful for Dr. Calder's care, especially his seeing me so quickly and on a Sunday. – Christina F.
My first visit at Berks Eye was more satisfying than I expected.

They were so nice to me, they said I would be seen right away and calmed my fears.
Dr Calder saw me, did a total exam. He then took the time to completely explain what had happened to my eye and that I would be ok. I have recommended this eye practice to others. From the front desk to the doctors and staff they were the best. – Cathy B.
