This is a hopeless book. It is just a miscellaneous collection of articles, mostly mediocre.
A major part of the problem is that there are simply too many articles. Leaving aside the introduction by Michelle Tempest, which is mainly hype ("it is a rare privilege to be able to discuss a topic that is literally a matter of life and death"), there are 34 articles in about 320 pages, including a fair amount of blank space. Authors simply do not have space to develop ideas.
The editor seems to have confined herself to cajoling a collection of people, each well-known in their field, to write the articles. There is no common theme, no connection between the articles. Sometimes different authors have wildly different ideas, but there is no confrontation between them and the ideas are not sufficiently developed to make any kind of judgment easy for the reader.
The only possible use I can see for it is to refer to it in a library if you happen to want to know what a consultant opthalmic surgeon thought about the issues facing opthalmology in 2005 (for example).
