Delta Eye Medical Group Delta Eye Medical Group is a full-service ophthalmology practice with three locations in Central California (Stockton, Lodi, and Tracy). The origins of the group go back to the early 1970's when Dr. Robert Hopkins went on a medical mission trip to India, and Dr. Alan Nakanishi came to fill in for him. When Dr. Hopkins came back in 1973, the two started Delta Eye Medical Group, and the physicians have continued the commitment to medical missions while providing complete state-of-the-art medical and surgical eye care for all ages.
Services
Delta Eye Medical Group has been serving patients for almost four decades in San Joaquin Valley. It is comprised of five Board Certified ophthalmologists and two licensed optometrists who are dedicated to state of the art comprehensive medical and surgical eye care and vision services. The group practice has three locations in Central California, serving communities in Lodi, Stockton and Tracy; with Optical dispensaries in each office. A few years ago, I decided to have laser eye surgery to correct my lifelong problem with nearsightedness.
The physicians at Delta Eye are pleased to introduce to you their colleague, Dr. Julio Narvaez. Dr. Narvaez has been a full Professor of Ophthalmology at Loma Linda University School of Medicine where he has been a faculty member since 2003. Dr. Narvaez graduated from Loma Linda University School of Medicine in 1992 receiving the Roger Barnes Humanitarian Award, and membership into the Alpha Omega Alpha honors society (top 10% of his class).
On-Tat Lee, M.D is a California native but has spent his whole life living and studying in various locations in the state. Dr. Lee received his undergraduate degree from UC Berkeley before studying medicine at UC Davis. He then completed his medical internship at UCSF Fresno and ophthalmology training at the USC Roski Eye Institute.
Many patients become overwhelmed when they hear that they have cataracts and get concerned about the surgery that will follow. It is completely normal to be nervous about any type of surgery. It is however, a myth that cataract surgery is painful and dangerous to perform. According to many sources, cataract surgery is one of the most commonly performed Medicare reimbursed surgical procedures performed in the United States today.

Was referred to Stocktons Delta office for Cataract Surgery. Had a pre-Op appointment scheduled for Fri. Received a call from the office to change the appointment to Wed at the Lodi location. I kept the appt and my eyes were measured for lenses. The day before surgery I was informed my surgery was cancelled because I failed to keep the pre Op appt.

Deeply incompetent office. They had a typo on my prescription and then had no clue how to fix it, making me waste two lunch hours trying to correct their mistake. They also did not warn me that my insurance wouldn't cover my appointment (even though it has in the past and they asked for a copay up front) so charged me $80 out of pocket for a 10 minute visit with no change in my prescription from last year.

This was my third visit with them and it will be my last. Edit: still getting bills from them even though I paid in full at the time of the visit. I'm going from two stars to one

Delta Eye Medical Group is a wonderful professional group committed to providing the best possible care for the eyes. I have been a patient of this office for over twenty years. All of the staff are friendly, helpful and compassionate. The physicians are very skilled and also take the time for explanations which is important especially when one considers just how important eye sight is!

Very helpful and friendly staff to take their time and accommodate patients' needs. My experiences with Delta have been amazing! Belinda from the Optical Dept. is super nice & took the time to teach me how to wear my contacts (first time wearer so as you can imagine it took me a while!) and I am in good hands with Dr. Julie Tse; I trust her 100% with the health of my eyes. Delta is fantastic and definitely recommend them to anyone; I'll never switch to another! 10/10 true professionals

My experiences with Delta Eye Medical Group, Dr. Jeffrey Ing, and his office staff, were accommodating and comforting to my needs. Being a Christian myself, I was most impressed with the option that Dr. Ing will pray with you at the time of your surgery. I am very happy to refer my friends to Dr. Ing and Delta Eye Medical Group.

The staff supporting Dr. Ing are professionals. They listen and provide information that make each visit a learning experience for their patients. Dr. Ing is a pleasure to work with as I seek to improve my overall vision & eye care. As a patient for more than five years, I have recommended his practice to several of our friends.
