Extremely likely. I tell everyone about the character and expertise of Dr. Krishnan. I would not have my left eye much less eye sight without the knowledge and proficiency of this excellent Doctor. Corpus Christi is truly lucky to have him.

Dr. Krishnan is an excellent doctor ... always efficient, caring and willing to meet you in the middle of the night if necessary. Those attributes are hard to find in the medical field. You rarely have to wait long to see him. His staff and office environment reflect his professionalism and high standards, as well as pleasant demeanor.

Our compliments to your office for beginning our appointment ON TIME!!!!! This is one of the biggest improvements we have noticed since Dr. Krishnan has taken over this practice. Today, we arrived & completed our visit within one hour! We also appreciate the sincerity of the office staff. EVERY employee is kind, thoughtful, & seems happy. We are especially fond of our technician, John. We express our preference for him when we arrive because he is smart, quick but thorough, & pleasant.

Felt very rushed not comfortable with procedure and no reassurance given. 3- minute visits for $ 55.00 co-payment. Laser surgeries are ran back to back-felt like a herd of cattle. He doesn't take your symptoms serious are addresses any concerns.

in Port Aransas, TX/Fife Lake, MI |
I have aggressive glaucoma, and I'd had seven surgeries from a doctor in another state that all failed. I've lost my peripheral vision, and was losing more vision because my pressures could not be controlled. Dr. Krishnan performed two surgeries on me, and the second one, the implant of a tiny shunt, worked. My pressures are now under control for the first time in several years. I am grateful to Dr. Krishnan, and I'm celebrating having stable vision and normal pressures because of his work.
in Corpus Christi, TX |
My first visit was on June 21 and I was very pleased with everything. The teck was very friendly and listened to all of my concerns then when I saw Dr. Krishnan he explained what they saw and how he could help me. He took his time with me and let me tell him what has happened to my eyes in the last year. I am very pleased with everything

I had cataract surgery on left eye, April 2017. For me, all went well. The impairments caused by my cataract have cleared with improved vision clarity. I found Dr Krishnan to be congenial, skillful in his surgical practice and would spend the time answering any questions that may be posed before and after surgery. I had a positive experience with him and the Eye Institute staff with which he is associated.

in Laredo, TX |
Was sent to San Antonio first by my local Dr but best in SA backed up several months but one of the best Dr in SA suggested I try Doctor Ravi who he considered very good and top notch so we tried, we own a house on the island and live in Laredo so this was very convenient since we dont own a house in SA. Doctor was much much better than we expected. Dr Ravi is the best Doctor I have seen so dropped my Laredo doc and switched. I have glaucoma. I am very glad I was referred to Dr Krishan.
in TX |
Referred to Dr Krishnan for cataracts. He presents as a very caring physician and will stop and answer all of your questions. I had excellent results from my cataract surgery. -- my vision was immediately very much improved!! His office staff is very professional and knowledgable. Especially in instructing me and preparing me for scheduled cataract removal and lens implants. Again, I highly recommend Dr Krishnan if you are considering cataract surgery.

Without Dr. Krishnan ,I guarantee I would be blind today. Money, his inconvenience comes long after his Patient does! Highly skilled in the most advanced procedures. You could not go wrong with Dr. Krishnan and his very competent staff. These comments come from experience and my heart! Thank You Dr. Krishnan.

From start to finish, Dr. Krishnan and his entire staff have been incredible. Their office runs like a well oiled machine. His staff is incredibly friendly and appointments run in a timely manner. I have already referred my sister and will continue to refer anyone that has vision issues.
in Corpus Christi, TX |
Had to wait 40 minutes past the appointment time to start. Then different steps went slowly with more wait in between. Only saw the doctor about 2 hours after the appointment time, and for too short of time, as we had an other appointment.
in Corpus Christi, TX |
I was very impressed with the total experience. I had the first cataract removed 2 weeks ago, and the second one yesterday and my vision is already so much better. Dr. Krishnan was always very professional. I would absolutely recommend him to anyone!
in Portland, TX |
I highly recommend Dr. Krishnan and his staff. They were friendly, professional and able to answer all my questions regarding my procedure. I was pleasantly surprised at how Dr. Krishnan spent so much time with me and didn't feel rushed even though he had a very full schedule. My appointment times were within 15 minutes of what I scheduled. His professional ability as a surgeon was excellent!

Dr. Krishnan did cataract and stents on both eyes and I am completely satisfied, no pain didn't even know I had surgery. Very polite and never rushes during office visits. Highly recommend his expertise.
in Ingleside, TX |
Had cataract surgery. Dr and staff were warm and welcoming. Took time to explain pre-op and post-op requirements. Did not get impatient with questions. Answered them all without rushing and making me feel stupid. Took time to help me feel at ease prior to the actual surgery and in recovery. Did excellent work. Dearly hope he stays this way and not get the fat head later on, thinking he's God's gift and treat patients like cattle.
in Corpus Christi, TX |
He has taken care of my eyes for years and he and his staff has done a very good job with little time wasted in the waiting room
in Corpus Christi, TX |
I am a person with anxiety and have a fear with new Dr. I can tell you that you will love Dr. Krishnan. I had surgery on both eyes and received a torque lens. I'm 61 years old and couldn't see even to drive. I also had to get glasses but have wore since I was 9. One thing I can tell you I haven't been able to see so good in years. I am one happy client and would recommend him 100 per cent. Staff excellent and very caring. I can't thank you enough Dr.Krishnan.

in San Antonio, TX |
I was sent to Dr Krishnan by my routine glasses & contacts Dr. I had been dealing with pink eye and couldn't get my rt eye contact out for 3 days. When I did get it out I felt a pop and severe pain. That is when I was rushed over to Dr Krishnan's office. Every single person in this office was so amazing & knowledgeable it changed my fear to confidence. He sent on into Baylor eye inst. to get a transplant. Because of this Dr I will be able to see out of both eyes again. Thank u doesn't begin

This doctor is excellent. His staff are very supportive and polite. I was consistently treated with dignity and respect and well as a nice level of informal friendliness. The surgery and its results are spectacular. I have nearly 20/20 vision as a result of the surgery in my right eye. This has never been the case for me. Thank you for this wonderful gift of clear vision. I look forward to getting the other eye done asap. Thank you to Dr. Ravi and his whole staff. Janice

Dr. Krishnan is one of those special doctors. Not only is an excellent ophthalmologist, but he truly cares about his patients. How many doctors do you know who would give you his home phone number and tell you to call if you have any questions or problems after a procedure?
in Corpus Christi, Texas |
Dr. Krishnan performed the surgery on my left eye several years ago. The results were amazing. When I had a major problem with my right eye recently, I didn't hesitate to go back to him. Having to wait 2 months for an appointment, I called a few other eye doctors. Something kept telling me to wait on Dr Krishnan. I had my surgery done on June 20, 2016. So far, it's been great. i had the Toric Lens Implant, so we will see how it works. Also, Sandy was outstanding in every way
in Corpus Christi, TX |
Regardless of who I spoke with over the phone or who I encountered in the office, I was always treated with respect and consideration. Each staff member answered questions I posed in a thorough and friendly fashion. They listened well and anticipated my needs and concerns. How they treated me spoke volumes of who Dr. Krishnan is: professional, skilled, and grateful. I was where I was meant to be. Psalm 50:15 Call upon Me in the day of trouble; I shall rescue you, and you will honor Me.

I am very impressed with Dr. Krishnan. He was recommended to me when I moved to Corpus by Dr. Compagna. He is very kind and quiet-spoken. His staff is friendly and easy to talk to.
