Queratopatia Estromal Induzida por Pressão Após Facoemulsificação: Relato de Caso

Introdução: Descrição de um caso clínico respeitante a queratopatia estromal induzida pelo aumento da pressão intraocular (PISK) após facoemulsificação num doente previamente submetido a implante de anel intra-estromal por ectasia pós cirurgia refrativa. Descrição do caso: Doente do sexo masculino de 53 anos com história de ectasia pós LASIK no olho direito, foi submetido a facoemulsificação e implante de lente...

Anterior Surface Measurements Correlation and Agreement Between Rotational Sche...

PURPOSE: To evaluate the inter-device agreement between Placido -based topography (Topolyzer Vario, WaveLight, Alcon Laboratories, Inc., Ft Worth, Texas, USA) and rotational Scheimpflug tomography (Oculyzer II, WaveLight, Alcon Laboratories, Inc., Ft Worth, Texas, USA) for measuring anterior corneal surface parameters. METHODS: Fifty eyes from 50 subjects with no ocular disease were included in this study. The ...

Dynamic corneal deformation response and integrated corneal tomography

Measuring corneal biomechanical properties is still challenging. There are several clinical applications for biomechanical measurements, including the detection of mild or early forms of ectatic corneal diseases. This article reviews clinical applications for biomechanical measurements provided by the Corvis ST dynamic non contact tonometer.

Integration of Scheimpflug-Based corneal tomography and biomechanical assessmen...

PURPOSE: To present the Tomographic and Biomechanical Index (TBI), which combines Scheimpflugbased corneal tomography and biomechanics for enhancing ectasia detection. METHODS: Patients from different continents were retrospectively studied. The normal group included 1 eye randomly selected from 480 patients with normal corneas and the keratoconus group included 1 eye randomly selected from 204 patients with ke...

To test correlations between Scheimpflug optical densitometry and ocular higher-order aberrations (HOAs) in patients with mild nuclear cataract.

Ectasia detection by the assessment of corneal biomechanics

Application of different Scheimpflug-based lens densitometry methods in phacody...

To evaluate the correlations between preoperative Scheimpflug-based lens densitometry metrics and phacodynamics.
