This book is a valuable update on understanding IOL surgery for ophthalmologists in training and in practice. Broadly, the book is divided into six sections dealing with three main concepts: 1) IOL selection for routine and complex scenarios; 2) IOL complications and their management; and 3) IOL implantation in eyes with compromised capsular support.

There are 28 chapters over 211 pages written by renowned experts in the field. It is a comprehensive text that addresses a range of topics on advanced IOL surgery and challenging case scenarios. It is compiled in an easy to read manner and supported by online videos of surgical techniques.

Section one of the book provides an overview of the history of IOLs, IOL materials and designs, followed by chapters on optimising IOL selection. I found the latter half more relevant to my practice. It details the concept and principles of IOL selection, toric IOL calculations, presbyopia correcting IOLs and IOL calculations after refractive surgery. The book can be used as a learning resource as and when one is faced with a difficult clinical scenario – there is no need to follow the chronological order of the chapters.

Section two deals with the complications of IOL surgery such as IOL refractive surprises, managing residual astigmatisms after toric IOLs, IOL dysphotopsias, uveitis glaucoma-hyphema syndrome and IOL decentrations necessitating IOL repositioning and exchange. The chapter on IOL repositioning and exchange has very good photographs showing the critical surgical steps and is also complemented by online videos demonstrating a variety of surgical techniques.

The third section is devoted to IOL implantation with compromised capsules. There is something for everyone in this section. While the junior trainee will benefit from the chapters on sulcus IOL placement, optic capture and capsular tension rings, more senior trainees and new consultants may find IOL-iris enclavating and iris suture fixation techniques useful in their day to day practice. The seasoned and adventurous ophthalmologist may like to learn techniques of scleral suture fixation, intrascleral haptic fixation of a PC IOL (glued IOL), pupilloplasty, suturing iris defects and prosthetic iris device implantation from the experts.

The last two chapters in the book are futuristic and brief, providing a glimpse of the newer generation IOLs. Overall, this book is a useful resource for anyone who undertakes IOL surgery. It prepares one for challenges that may inevitably arise during cataract surgery which is half the battle won. The assimilated expert opinions with well-written chapters referencing current evidence ensure that the book is one of a kind.
