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 has been fully updated to provide the latest developments in corneal tomography using the Pentacam system.
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.
The book is highly illustrated with colour images, figures and clinical examples. Previous edition (9789386261106) published in 2018.
Authored by recognised expert Mazen M Sinjab, this book is the first to:
Establish screening guidelinesPresent a new systematic interpretation of corneal tomographyPresent a new practical subjective scoring system, the Sinjab’s PS3 algorithmPresent a new algorithm for best IOL selection in lens-based and modern cataract surgery, the Sinjab’s PSIS algorithmDiscuss false positives and false negativesAddress tomographic features of corneas after keratorefractive procedures and after corneal graftsStudy in-depth corneal irregularities using a new 4-selective composite mapPresent a new understanding of corneal astigmatismAddress the new concept of corneal refraction and related subjects such as objective corneal dioptric power and astigmatic disparityShow the importance of enantiomorphismPresent entities misdiagnosed as ectasia and offer guidance on how to differentiate them from ectasiaDiscuss the progression criteria of ectatic corneal diseasesApply a detailed corneal tomography for cataract surgery1 411 kr

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.

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.
