I had a consultation early Thursday, was able to get in for pre-op same day, and had surgery the…read morenext day! Absolutely unheard of, and if I had to guess, luck of timing! I was expecting to be scheduled a few weeks out, but glad I had the luck of the draw (i guess) lol. Fabulous staff, awesome doctor, Dr Pirnazar did my surgery and throughout, informed what was happening next, and what was to be expected. It made the understanding so easy, and kept me at peace. I'm now a ~week post-op, and very happy with the results. I have slight glare when looking at lights, but that can be expected. I'm following the drops as prescribed, and can notice every day improvement. I'm very happy with my decision, and would recommend it to anyone in fear, and anyone who's even remotely considered it, I held off for too long,. I opted for contoura which happens to be the latest and most advanced tech.

Oh this place. Beware of the billing and medical nightmare you will have with this place. I…read morereceived bills for which my insurance had processed and sent me EOBs with member rates. The company/billing denied receiving EOBs from my insurance. I explained we paid copays and I am being billed non member rates and that these claims need to go to the secondary payor as well. They didn't have record of my copays, and denied getting EOBs. So, I emailed my EOBs over, my credit card receipts and they said they couldn't open the files (who can't open a PDF). So I sent them again and as screenshots, they denied receiving them. I sent my EOBs to the email they provided me 5 times. They said fax them (who faxes stuff in 2026?), so I went to my local FedEx, faxed them, they denied receiving them. After over a month of this, and even Aetna calling them (with me on the line), they continued to send me bills with non adjusted balances. I filed a complaint with the BBB. Two weeks later I get a call from someone named Melanie. She said she has "found" my EOBs and will work to get these all resolved and submitted claims to the secondary payor. She gave me her number to call her if I had any other issues with getting my refunds. This was back in December. It is now end of February and my primary insurance (Aetna) and my secondary insurance have paid these claims in full. I am owed a refund of my copays that I paid in the office. I called billing, they said they don't process refunds. I called the office, they said contact the business department but they don't have a number to give me, billing will have this. I called billing again, they said we can't give you a number, call the office again. I've left messages, asked for call backs, no one is calling me back. I called the number Melanie gave me and it goes to a visa call center. What in the world is wrong with the place!?? I have gotten no where. The doctor (Eric Areiter) wasn't even that great, my husband saw him a few times with no results, would have his appointment cancelled or passed onto an NP or PA and we have since gone somewhere else and have had his issues resolved. This place is awful. My billing issues are still not resolved.
