He always takes the time to explain the options available. I am particularly appreciative of the way he treated my cataracts, clearly giving me the information needed to make the best decision for my eyes, and performing the surgery skillfully. The results are great, giving me excellent vision.”

“I had bilateral cataract removal and lens replacement by Dr. Kreidl at Avista Surgery Center. The pre- and post-op instructions were written out and very easy to follow. The staff at the surgery center was excellent. I am very happy with the outcome and with the support of Dr. Kreidl and his office staff.”

“Dr. Kreidl has been my ophthalmologist for several years. I developed cataracts over the years and Dr. Kreidl suggested watchful waiting. Recently he recommended surgery and was very helpful in explaining why surgery was indicated now and describing the procedure. The surgery went well with minimal discomfort. I had been wearing bifocals for 35 years but after cataract removal I no longer need glasses for reading or distance. I am very pleased and thankful for Dr. Kreidl's skill and kindness.”

“I cannot praise Dr. Kreidl and his medical assistant, Lina, enough for the outstanding care they provided to my father. Dr. Kreidl's approach to patient care is truly remarkable. He took the time to thoroughly listen to my father's concerns, patiently answering every question and ensuring he fully understood his diagnosis and treatment options. His depth of knowledge and ability to communicate complex medical information in a clear and empathetic manner instilled confidence in my father and our family. Thanks to Dr. Kreidl and Lina's exceptional care, the health of my father's eyes has improved significantly, and our family has peace of mind knowing that he is in the hands of such capable and compassionate professionals.”
