Refractive surgery is eye surgery to improve the refractive state of the eye and reduce or eliminate the need for glasses or contact lenses. The most common type of refractive surgery uses lasers to reshape the curvature of the cornea. This book is a practical guide to the latest advances in refractive surgery procedures. Beginning with an introduction to the evolution of refractive surgery, the next section discusses pre-operative workup, patient evaluation, and decision making. The following sections cover different refractive procedures including corneal ablative, refractive lenticule extraction, lens-based surgeries, enhancements and retreatments, and presbyopia (a condition associated with aging). The final section covers a selection of miscellaneous topics such as bioptics, collagen cross-linking, intracorneal ring segments, incisional surgery, and challenging scenarios. Each section is highly illustrated and provides in depth detail on machines and laser platforms, surgical techniques, outcomes, and potential complications and their management. Key points Practical guide to latest advances in refractive surgery Covers numerous different procedures In depth detail on techniques, outcomes, equipment and complications Highly illustrated with clinical photographs and figures

Introduction: This PhO study investigates finite objective and subjective clinical outcomes of refractive surgery. Methods: A series of studies was conducted to investigate laser retreatment procedures, a comparison between the OPO-Scan and WaveScan aberrometers, a comparison of aberrometry changes following laser in situ keratomileusis (LASIK) and laser-assisted subepithelial keratectomy (LASEK), internal aberration changes following LASIK, the development of a quality of vision (OoV) questionnaire and the refractive outcomes of the SCHWINO Amaris excimer laser. Results: Good visual and refractive outcomes were found with LASEK retreatment and a high incidence (23%) of epithelial ingrowth occurred following flap-lift LASIK retreatments. In the comparison between the OPO-Scan and WaveScan, medium consistency was found for aberrations z;' and z~ with poor consistency for all other aberrations. In the comparison between LASIK and LASEK, both procedures caused increases to spherical aberration with LASIK additionally causing increases to two fourth-order aberrations and LASEK causing increases to two fifth-order aberrations. Investigations into internal aberrations found LASIK increased internal spherical aberration which attenuated the increase in anterior corneal spherical aberration. A OoV questionnaire was successfully developed utilising Rasch analysis demonstrating good precision, reliability, and internal consistency with good construct validity and test-retest reliability. The SCHWINO Amaris was found to be effective for the treatment of a range of refractive errors. Conclusion: Significant clinical finding were found for laser retreatments and primary treatments with two different laser systems. Aberrations were found to be poorly correlated with the OPO-Scan and the WaveScan. An effective OoV questionnaire was developed which may be used in prospective clinical and research studies."

Custom LASIK: Surgical Techniques and Complications is the most comprehensive resource on LASIK currently available. This new edition of LASIK: Surgical Techniques and Complications has been revised and updated to include the latest in wavefront technology, new microkeratome instruments, and the most recent surgical procedures, in addition to various complex cases and complications. The collaboration of Drs. Buratto and Brint, along with a team of international surgeons, have produced a complete text specifically to improve the quality of vision. Amateur surgeons benefit from the format in which basic surgical procedures are explained. Advanced laser procedure with ablations and intralase without the blade are more advanced techniques specifically detailed to assist the expert surgeon. The scope of this new edition is designed to provide the multitude of LASIK techniques that have emerged and the technological advancements that have made them possible. With over 1,000 color illustrations demonstrating the various procedures and concepts, readers are able to develop a more thorough understanding of LASIK. These images supplement the wealth of surgical strategies presented throughout this resource.

Refractive Eye Surgery, Second Edition is a comprehensive text on the history, evolution, and current status of refractive eye surgery, written entirely by one author, a pioneer in the field. Surgical methods and patient workup are included in separate chapters describing each surgical technique. Among the surgeries described are lamellar, laser, and intraocular refractive surgery, radial keratotomy, surgery for astigmatism, and scleral shortening. The book discusses complications, shortcomings of techniques, and results of surgery. Extensive color illustrations describing the techniques, as well as the optical properties of the cornea and its surface topography make this a valuable surgical atlas. Methods of measuring and analyzing the corneal surface, the derivation of the corneal shape factor, and basic topics such as ametropia, myopia, and astigmatism are also covered.

The Art of Refractive Surgery aims at providing a simplified and step-wise approach to ophthalmologists for planning and performing various refractive surgeries including corneal, lenticular, or combined approaches. Refractive surgery is extremely challenging as suboptimal outcomes are unacceptable. This field has seen huge developments in the recent years with advancements in investigative modalities, better laser delivery systems, wider range of options of refractive surgeries, and improved eye-tracking devices. However, the selection of ideal surgery for every patient remains a challenge and a thorough understanding of basic concepts can aid in decision-making. The Art of Refractive Surgery deals with these basic concepts, and provides certain surgical and planning tips, which have been derived through years of experience. Key Features: Interactive style of the narrative ideal for refractive surgeons, ophthalmologists, fellows, and residents who wish to update their refractive surgery knowledge Practical examples with individual case-based approach for planning, decision-making and surgical management in a variety of scenarios Extensive review of literature and includes the latest meta-analysis and clinical studies Numerous illustrations and simple language to elucidate complex refractive situations Surgical videos explaining each refractive surgery step-wise for deeper understanding
