    In 2021 Kersten Diana, MD insisted I needed Cataract surgery for both of my eyes. Just prior to…read moreKersten Diana, MD performing Cataract surgery to my Right Eye my vision was 20/30 (R) & 20/40 (L). And, just prior to Kersten Diana, MD performing this surgery I was able to clearly see our distant Saddleback mountains. And clearly read the small print on vitamin bottles, all without glasses. Yet, Kersten Diana, MD insisted she begin Cataract Surgery with my right eye. I was reassured,"THIS IS TO PROTECT YOUR FUTURE VISION." I went along with Kersten Diana, MD's recommendation. (Kersten Diana, MD, Ophthalmologist @ Harvard Eye Associates in Laguna Hills, CA). I found out after the Cataract Surgery of my right eye that it was absolutely UNNECESSARY. MOST IMPORTANTLY, KERSTEN DIANA, MD'S CATARACT SURGERY TO MY RIGHT EYE MADE ME LEGALLY BLIND (20/200) IN MY RIGHT EYE. MAKING ME FOREVER LEGALLY BLIND. Imagine, KERSTEN DIANA, MD had planned next to perform Cataract Surgery to my left eye. Also, after this unnecessary life altering Cataract Surgery given by KERSTEN DIANA, MD I had an appointment to see KERSTEN DIANA, MD at her office where she had a huge desk. I sat across from her with my Husband. By then the after surgery cotton eye patch was off and I had just recently seen a highly respected Ophthalmologist who had my right eyesight tested. It had become 20/60 and steadily worsened. As I sat across from KERSTEN DIANA, MD in her office at her huge desk I said to her, "I had an Optometrist test my eyesight just after I followed your directions in caring for my right eye after your Cataract Surgery to my right eye. My right eye vision was 20/30 just before your surgery, it is now 20/60 and worsening. KERSTEN DIANA, MD looked at me but said nothing. She squeezed both her hands into fists and pounced each one twice on her desk as she raised her body from her huge desk. She, KERSTEN DIANA, MD then STOMPED OUT OF HER OFFICE. She never made any effort to contact me. I never saw her again. P.S. The severe damage resulting from the unnecessary cataract surgery to my right eye became 20/200 one month or so after the one year deadline to file a Malpractice Lawsuit. She lost nothing for unnecessarily blinding me. The Medical Board and general public are not aware of Kersten Diana, MD's willful medical neglect and unapologetic medical behavior.

    If you ever get the chance to be under the care of Dr. Kersten, you will never want to find another…read moreophthalmologist. Not only does she take her time with patients, she practices with genuine care & ethics. Her office is well staffed & the technology is always up to date. If you want the best eye care, I would recommend finding her at Harvard Eye Associates. She does cataract surgery & LASIK!
