Sadly, Dr. Larry Nierman's unprofessional attitude and lack of courtesy was so bad that the fact they were probably medically correct still warrants a 1 star. I had glasses made by Nierman 6 months ago. For the last 6 years my prescription has not changed (though my glasses were about 12 years old and outdated, my contacts were updated). This consistency was partly due to my wearing rgp lenses. When I was considering LASIK, I decided I needed to get new and updated glasses to wear for a few weeks leading up to surgery. When I first tried the glasses on, I complained about some blurriness in lights and was told by the Nierman associates that this was because we did not upgrade to anti-glare lenses and because I wasn't used to glasses. Totally my mess up here - I should have tested them full time right then. When we decided to postpone LASIK until later, I had no need to wear my glasses full time until last week when I lost a contact lens. After wearing the glasses full time, the blurriness was still there and I was getting headaches with impaired vision. I called Nierman immediately to ask if they could see me, and was given an appointment 8 days away as the soonest they could see me. Since I couldn't wait 8 days, I went to an optometrist in downtown who measured my eyes and came up with a prescription that was significantly different than the Nierman measurement in Feb. My new optometrist explained my glasses from Nierman had a prescription that differed greatly than this and suggested I take them back to Nierman to discuss the issue.When I went in for my appointment at Nierman yesterday, the tech who received me was friendly and tried calling my vision insurance to see if they would cover lenses if the prescription changed. When my vision insurance said no, and that my prescription is only covered annually, I asked to speak with the doctor to see if he could explain what happened. It seemed unlikely that my prescription could have changed that drastically in 6 months and my husband and I wondered if there was a mistake made in Feb when my exam was conducted.Larry Nierman saw us (as he should have, considering I had to make an appointment to even come in, and waited 8 days for this) and proceeded to brush us off as complete idiots. However, when we questioned whether or not a mistake could have been made, his answers were full of contradictions. On one hand he said it was impossible that a mistake could be made because optometry is a science and it's not possible for prescriptions to be wrong. On the other hand, he said my new prescription from my new optometrist was not trust-worthy and must be inaccurate because it was so different from Feb. He said he wouldn't trust my new prescription and needed to re-examine my eyes, but then wanted to charge a full exam fee (it wasn't until the end that he finally offered to do the exam for free). He said that I should have been out of my contacts for 3 days before coming for my original exam to get a more accurate reading, but when I explained that no one ever advised this to me, his response was "It's not my fault you chose to ignore this." This is like a doctor blaming a patient for an inaccurate blood test due to not fasting, when the doctor's office didn't tell the patient to fast in the first place. He then said they make glasses depending on the use - basically if someone wears contacts full time, and needs glasses for only that hour or so before going to bed they don't require as accurate a reading, as those who are wearing their glasses full-time. I'm not sure that makes sense, but even if it does, I had told the doctor the reason I wanted glasses is because my current glasses prescription is outdated and I'll need to wear them full-time before the lasik procedureHis response was to complain that he had other patients to see and we were wasting his time. There were no other patients in the office, and I HAD AN APPOINTMENT. He was all over the place, pulling arguments out of thin air instead of calmly discussing this with us. When my husband tried to get him back on point, he held up his hand and yelled "I'm talking!" Seriously?His response was always to just blame me for waiting 6 months or telling us that eye readings are never accurate. Nierman was rude, condescending, hypocritical, and offensive. He's right that I should have come in earlier, but he's wrong to blame me for not being out of my contacts prior to the exam when no one ever advised me to do so and he's wrong to ignore my original (timely) complaint that was waved off as a result of not having anti-glare lenses. They're the experts and I put my faith in them and their expertise. In this case, that was my biggest mistake.
