A former Mankato Clinic ophthalmologist accused of sexually assaulting two of his patients is facing new allegations from a third former patient. 50-year-old Todd James Gavin has been charged with 4 counts of criminal sexual conduct and was in court Friday for a pre-trial hearing. Gavin is currently working at the Madelia Clinic, but the alleged assaults took place in 2010 when he was working in Mankato. One woman said she was asked to remove her clothing during an exam to see if a shingles outbreak had harmed her eyes. The second woman said that Gavin touched her inappropriately after having her bare her breasts and remove her pants. The third woman’s allegations of sexual assault will not result in additional charges because of the length of time that has passed, but she may be asked to testify at Gavin’s trial. Since the alleged assaults occurred Gavin has paid a civil penalty of over $4,000 and was required to complete a “boundaries” course. He is also required to be accompanied by a chaperone if he examines patients below the neck. He’ll be back in court January 31st.
