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.Key pointsThird edition of bestselling guide to interpretation of corneal topography using PentacamFully revised with latest advances in the field and two new algorithmsAuthored by renowned ophthalmic specialist Mazen SinjabPrevious edition (9789351523970) published in 2015
