Prevalence of Astigmatism in Post Operative Cataract in University of Port Harcourt Teaching Hospital, Nigeria

Clinical cards of all cataract patients operated on in the eye centre of the University of Port Harcourt Teaching Hospital (UPTH) between 2002 and 2006 were studied. The study comprised 114 eyes of 100 patients who had cataract surgeries done within the 5-year period of this study.

Among the names of contributors are many new ones,some of which have been prominent in the journals during the last 8 years. We miss the name of Homans and his beautiful article on thrombosis...

Anterior surface-based keratometry compared with Scheimpflug tomography-based total corneal astigmatism.

PURPOSE Description of total corneal refractive power (TCRP) astigmatism by ray tracing using a Scheimpflug tomographer. METHODS Analysis of Scheimpflug tomography measurements to determine 3-mm-zone TCRP astigmatism (CATCRP) by ray tracing calculations, astigmatism in 15°-zone from simulated keratometry (CASim-K), anterior-surface astigmatism (CAant), and posterior-surface astigmatism (CApos...

Effect of acupressure on post operative nausea and vomiting

Introduction: Nausea and vomiting is one of the most common postoperative complications. Aside from pharmacological interventions, other complementary healing modalities have been introduced to assist patients in decreasing this complication.
