Corneal tomography is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. This procedure may be carried out with a Pentacam, which uses a rotating camera to create a 3D image of the anterior of the eye. This fourth edition provides the latest developments in corneal tomography using the Pentacam system. Previous edition (9789386261106) published 2018. Beginning with an introduction, the following sections cover corneal maps and profiles, corneal refraction, Wavefront analysis, systematic interpretation of corneal tomography, and corneal tomography in ectatic corneal diseases.

This book provides a list of concise extemporaneous ophthalmic preparations, and standardizes the formulation of the products by suggesting specific strength, route of administration, appropriate vehicle, and method of preparation. Pharmaceutical industries have greatly expanded their share of ophthalmic drugs in recent years. However, physicians and pharmacists are frequently called to prepare sterile products intended for ophthalmic use due to lack of availability of licensed drugs in the market. This book contains the most appropriate formulation of each medication based on published and documented stability data. Extemporaneous Ophthalmic Preparations is the first book of its kind, making it a unique and valuable companion for many physicians and pharmacy practitioners who are frequently engaged in the compounding of sterile ophthalmic preparation.

Corneal topography is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. This procedure may be carried out with a Pentacam, which uses a rotating camera to create a 3D image of the anterior of the eye. The third edition of this bestselling book has been fully revised to present ophthalmologists with the latest advances in the interpretation of corneal topography using the Pentacam. The book begins by discussing standardisation of capturing the corneal image and offers guidance on systemic interpretation. The text presents two new algorithms – the practical subjective scoring system (PS3) for laser-based refractive surgery and the practical subjective IOL selection (PSIS) for lens-based refractive surgery. New categorisation of ectatic corneal diseases, correlation of tomographic findings and their clinical applications, and the importance of corneal wave front, are covered in depth. The book concludes with four clinical cases to assist learning. Authored by recognised ophthalmic specialist Mazen Sinjab, the comprehensive text is further enhanced by clinical photographs and figures.

This book addresses customized laser vision correction, an integral management option for the treatment of irregular corneas. This type of treatment reshapes the corneal surface in order to improve both the quality and the quantity of vision by reducing high order aberrations. Beginning with an introduction to the basics of this science, each type of customized laser vision correction is discussed in a clear and didactic format for rapid attainment of information. Throughout this practical clinical guide, examples are supported with the most recent scientific material and a step-by-step systematic methodology is included to fit all levels of ophthalmologists.
