Dr Lean diagnosed partially torn retina in my right eye and repaired it with laser treatment at same appointment. He followed up frequently, including calling me directly within the next few days & seeing me once a week for three weeks to ensure the treat was successful and no further tearing occurred. I highly recommend Dr. Lean & Retina associates of OC for all retina care.
