Several years ago I located his practice after retirement, when I no longer had VSP coverage, and my vision care provider at the time, a major UC affiliated clinical practice, which was current with Age-related Macular Degeneration (AMD) refused senior medicare insurance. Dr. Ensor is among a very small number in the bay area, who is well versed and equipped in monitoring and in available treatment options for AMD, being on call 24/7 for emergencies in vision changes, and his office accepts medicare and other related senior insurance plans. But, more importantly he and his entire staff are sincere, empathic, and provide the highest level of patient-based care. My wife is now one of his new patients. We both appreciate how Dr. Ensor, his associates, & office staff are so pleasant, respectful & understanding of all of the challenges that patients deal with & present!

I recently had a troubling experience at Diablo Valley Optometric Group with Dr. Michael Ottati,…read morelocated at 2255 Ygnacio Valley Road, Suite C, Walnut Creek, CA. On April 7, 2026, I was denied an eye examination solely because I refused to undergo the Optomap procedure or sign a "Release of Liability for Internal Eye Health Exam", which I felt was being aggressively pushed by the non-medical staff. I've been a patient at this office for approximately 13 years, and I was surprised to find that despite my prior examinations, I had never been properly informed by Dr. Ottati about the requirements and necessity of the Optomap procedure while the doctor performed the eye examination. When I denied the service by the front desk staff, I asked to speak directly with Dr. Ottati about my concerns, but his justification for recommending Optomap was vague and unsatisfactory; he only said "it is recommended". What struck me as particularly concerning was the insistence from the front desk staff that I view a video about the Optomap (biased video by the product developer) and sign a "Release of Liability for Internal Eye Health Exam" in order to receive any services at all. This approach raises serious ethical questions about informed consent in medical care. Why is a non-clinical staff member pushing a medical procedure without proper justification from the doctor? To make matters worse, I later learned that my insurance covered dilation, the traditional method that allows a thorough assessment of nearly 100% of the retina, which is done as part of the routine eye examination (in my case conducted the previous year in 2025). I was denied the chance for my regular eye check-up even though, as later the my insurance company verified with Diablo Valley Optometric Group that the Optomap procedure was actually optional procedure. Comparing dilation (Tropicamide 0.5%) and Optomap is a choice between a traditional clinical "gold standard" and a modern, high-speed imaging technology. While Optomap is highly convenient, most eye doctors view them as complementary rather than as direct replacements. Doctors can see nearly 100% of the retina using the dilation (Tropicamide 0.5%). Dilation allows for a three-dimensional view and a more detailed examination of the extreme edges (periphery) of the retina and is covered by vision insurance. Doctors can only capture approximately 80% (200°) in one shot using the Optomap. It is used for low-risk patients who want to avoid the inconvenience of blurred vision, therefore is also helpful for children or patients who are sensitive to eye drops. Optomap is, in my case, an out-of-pocket fee ($39). Furthermore, the language in the "Release of Liability for Internal Eye Health Exam" document I was pressured to sign was alarming. It implied that without the Optomap, serious health conditions might be missed, which is misleading when dilation has effectively been used for my past examinations without issue. The reality is that the dilation method provides a comprehensive view of the eye and is also covered by my vision insurance. I wrote a letter to and strongly urged the California State Board of Optometry to investigate the practices at Diablo Valley Optometric Group. Patients deserve to make informed choices about their healthcare without pressure or coercion from non-medical staff. Based on the findings, I hope that the Board takes appropriate action to protect patients, possibly recommending that Dr. Ottati be removed from the VSP provider list. I am disappointed that I had to confront such unethical practices in what should be a routine medical visit. Proceed with caution if you decide to visit this office.

However, I struggled for over a year because the contacts still left my vision a little blurry when doing computer work, weren't comfortable for long periods, etc. I'd tried out multiple prescriptions and brands and was burnt out, but I needed to renew my prescription and had just moved so I figure I'd give Dr. Khela a try, expecting nothing would really change in my contact discomfort. I could not have been more wrong - she is a phenomenal clinician / wizard. She explained exactly where my discomfort was coming from (astigmatism!), got me in more comfortable contacts, explained why having one contact for astigmatism and one normal might help, and masterfully explained why computer work was giving me a headache and had a great fix. Her experience working with hundreds of patients doing deep squinty computer work really makes her an expert on modern eye fatigue and her solutions are creative and adaptive. I didn't know it was possible to be this wowed by your eye doctor but eye comfort is so underrated and I am grateful to have found the best doctor!

It's one of the many reasons she is a standout and why I wouldn't recommend anybody else, but her. If you want someone to thoroughly care for your eyes, answer your questions and provide you with a tangible treatment plan...SHE IS YOUR GO-TO! As an RA patient with iritis, I had serious concerns because I was getting the run-around by other doctors about my dry eyes and blurred vision. I had to make an emergency appointment to see her and she took me in that same day. Dr. Khela took her time to assess my eye history and confidently offered an actionable plan that reduced a flare-up within days. Thank goodness! Despite having gone to leading eye care institutes in Los Angeles, Dr. Khela was the first person to actually take swift action, dive into my concerns with dry eyes AND get me on a treatment plan that brought my eyes back to being healthy. Anyone who gets to be treated by her is extremely fortunate. She's the best at what she does. Thank you Dr. Khela for taking the extra steps to make sure I had the best care possible and also helping me find a pair of hip glasses that I love!

This might just be the greatest optometrist in America…read more.. Last night I scratched my cornea in my left eye while removing my contacts. I called today on the off-chance that they would have an available appointment and be able to fit me in. I am new to the Bay Area and hadn't found an eye dr yet. They told me that normally they didn't see new patients for eye problems, but they went ahead and found a time for me to come in today and get checked out. Let me tell you, I appreciated this SO much! I have amblyopia (lazy eye) in my right, non-scratched, eye. I have very very minimal vision in my bad (right) eye, so I need to protect my good (left) eye at all costs. A scratched cornea may not be a super huge deal for another person, but for me it could mean the difference between being able to see and being legally blind. I cannot express how much I appreciate being fit in the schedule on the same day! (I didn't even tell them any of this over the phone, they found me an appt without this knowledge. They rock!) The office is beautiful and up to date. The doctor was thorough and made sure to check everything out. He also suggested that when I come back in a week for a check up that they go ahead and do my annual exam as well. AWESOME! I was planning on sticking with this place anyway, and I was super happy that he suggested doing my exam as well when I come back. I'll be recommending this place to everyone!
