“It is no longer a huge effort to focus and I am not seeing double anymore. Thank you so much for correcting what was becoming a major problem for me! It is so nice to feel ‘normal’ again.”

“We are contacting you because we want to thank Wills Eye, Ophthalmic Partners, and especially Dr. Leonard Nelson and his team for all of their wonderful work with our daughter, Alyza.

This past weekend we had our daughter Alyza photographed and when we received the proofs from our photographer and were comparing them to the last set of photographs of her taken just a week before her surgery in March, we almost cried tears of joy!

Dr. Nelson and the staff completed the eye muscle surgery on our little baby, and we will admit we were nervous about doing the surgery at all. However, because of the high regard we have for Dr. Nelson and his experience, we put our trust in him. Thank God for his guidance in her care. When we look at Alyza’s beautiful blue eyes in these photographs, we know we made the right decision.

Thank you for all you have done.”
