Purpose: To analyze the astigmatic changes after cataract surgery with toric intraocular lens (IOL) implantation and determine the relationship between these changes and the final visual outcomes.
Setting: Vissum-Instituto de Oftalmológico de Alicante, Alicante, Spain.
Design: Prospective case series.
Purpose: To evaluate the clinical features of keratoconus taking into consideration anterior corneal aberrations, internal astigmatism, and corneal biomechanical properties and to define a new grading system based on visual limitation.
Setting: Vissum Corporation, Alicante, Spain.
Design: Retrospective case series.
Purpose: To evaluate the corneal volume, pachymetry, and correlation of anterior and posterior corneal shape in subclinical and clinical keratoconus.
Setting: Vissum Corporation, Alicante, Spain.
Methods: Eyes were placed into 1 of 4 groups as follows: keratoconus 2 (grade II), keratoconus 1 (grade I), subclinical (subclinical keratoconus), and control (normal eyes).
Purpose: To investigate the amount, type, and role of corneal higher order aberrations in both isotropic and anisometropic amblyopic adult patients.
Methods: A total of 125 eyes of 78 patients with age ranging from 18 to 67 years (30 patients with unilateral amblyopia, 17 with bilateral amblyopia, and 31 normal eyes considered as the control group) were included. All eyes received a comprehensive ophthalmologic examination that included corneal topographic and aberrometric analysis with the CSO system.
Purpose: The aim was to evaluate the anterior and posterior corneal aberrations provided by the Pentacam system in normal and early to moderate keratoconic eyes.
Methods: Fifteen normal eyes (normal group, mean age 32.60 +/- 7.
