Dr Hsia has done a Trabeculectomy in both of my eyes. The first one ended up with bleb too big and blurred my vision. Dr Hsia listened to my concerns and agreed to do a bleb revision. Revision helped some but we needed to do 2nd rShow moreevision and it worked!! I just knew that if we could get the bleb size down it would solve all issues which it did. It did require the 2 additional surgeries but it was so worth it!! Thank you Dr Hsia for listening to and hearing my concerns and thoughts!! Highly recommend!!

Mark H. • May 29, 2026

I got the feeling today that this practice did not respect my time. We arrived early for our appointment and then didn't get called for about 10 minutes after the scheduled start of the appointment. The technician conducted the basic exam including shooting the pictures of the inside of my eyes, etc. Then she dilated my eyes, took me to a waiting area, told me it would be about 10 minutes. About 55 minutes later we got called, only to be put on hold for another delay. Finally we did get to see the doctor, and that contact took about three minutes. Total elapsed time for this appointment was 90 minutes... about 80 minutes of which was spent waiting in various waiting rooms and waiting areas. Not acceptable in my mind! Disrespected my time. I understand having to wait my turn, but why have appointments if that appointment time means nothing and you just end up waiting and waiting and waiting for the process to move along.

Lawrence W. • May 21, 2026

I have been a patient there for the past three years. This facility, the doctors and the staff never fail you. They are the best. Highly appreciated and recommended.

Alireza S. • April 21, 2026

Dr. Hsia went out of his way to AuthorizeCenterwell Pharmacy to approve one of my eye medication’s even though it was not on their formulary. Initially, it was not approved, So again, Dr.Hsia went to the appeal and gave his reasons why the generic drug was not going to work for my eye. I highly recommend Doctor Hsia.
