With the rapid advancement of corneal topography and wavefront technologies and the increased application of corneal topography not only in refractive but also in premium IOL surgery, a new edition will be the foremost resource for both ophthalmologists and optometrists. In this Second Edition, Dr. Ming Wang, Dr. Tracy Swartz and over 50 contributors combine the important topics of refractive and premium lens surgeries and put corneal topography in the context of wavefront technology. With over 500 images, this edition gives special attention to the latest advances in these technologies. The state-of-the-art science and application of corneal topography for these anterior segment surgeries is well represented in this Second Edition, making it the latest and most comprehensive reference of these state-of-the-art technologies for refractive and for premium IOL surgery. Updated and reorganized to reflect changes in the technology.
