I joined AOOSIS many years ago after a poor experience with the MPS where I struggled to receive prompt and accurate advice on a problem. This led me to look elsewhere for indemnity cover.
The reason I joined AOOSIS was that as an organisation focused on ophthalmology I felt they had a clear understanding of ophthalmology and medicolegal issues rather than just medicolegal advice. As a small organisation with a dedicated legal team I have found that they do indeed have a clear understanding of ophthalmology and are responsive and effective.
The terms of the indemnity cover are clear and thorough in contrast with guaranteed cover in contrast to a discretionary based insurer.
