Preface

Cataract surgery is one of the most frequently performed surgical procedures in the world. Intraocular lens (IOL), as an integral part of ocular refractive system reconstruction, is playing a more and more important role in cataract surgery. Moreover, with the development of IOL technology and patients' increasing demands of postoperative visual quality, different kinds of premium IOLs, such as the toric IOL, multifocal IOL, trifocal IOL, accommodating IOL, and extended depth of focus IOL, are widely used in ophthalmology. The careful and exact understanding of the optical physical properties of each type of IOL, their advantages and disadvantages, and biocompatibilities is essential.

This book is fortunate to have outstanding contributors from different countries. We believe that IOL content has a practical and clinical interest for clinical ophthalmology. Moreover, we hope that this book provides a timely answer to a current clinical need.
