Corneal topography with an aberrometry-topography system [PDF]
Contact Lens and Anterior Eye, 2018 To investigate the agreement between the central corneal radii and corneal eccentricity measurements generated by the new Wave Analyzer 700 Medica (WAV) compared to the Keratograph 4 (KER) and to test the repeatability of the instruments.20 subjects (10 male, mean age 29.1 years, range 21-50 years) were recruited from the students and staff of the ...

Principles of Ray Tracing Aberrometry
Journal of Refractive Surgery, 2000ABSTRACT PURPOSE: Of all transforms of an eye, aberrations are significant when higher visual acuity is to be achieved. Ray tracing aberrometry developed by the Institute of Biomedical Engineering (Kiev) and first tested at the Vardinoyannion Eye Institute of Crete is a promising technique for eye refraction aberration and refraction mapping.

Essentials in OphthalmologyAbstract Intraoperative aberrometry (IA) has advanced high-precision ocular biometry from the clinic into the surgical suite. Additional optical biometric data during cataract surgery can enhance surgical decision-making and help improve fidelity and refractive outcomes of IOL implantation.

Principles of Hartmann-Shack Aberrometry
Vision Science and its Applications, 2000The optical principles of Hartmann-Shack aberrometry are described first using the language of ray optics, and then again using the language of wave optics. The tutorial concludes with a discussion of limitations of the method.

The basics of wavefront aberrometry
Acta Ophthalmologica, 2008AbstractWavefront technology has been first used by astronomers for years in order to reduce higher order aberrations induced by the earth’s atmosphere, it has been introduced into clinical eye care recently.<br /> Ophthalmological practice involves performing a full subjective refraction. The sphere, cylinder and axis of astigmatism are measured.

Evaluation of variables affecting intraoperative aberrometry
Journal of Cataract and Refractive Surgery, 2012To understand some of the variable refractive changes that occur during routine cataract surgery that could affect the accuracy and effectiveness of intraoperative aberrometry as it relates to the postoperative refractive state.John A. Moran Eye Center, University of Utah, Salt Lake City, Utah, USA.Comparative case series.Phase 1 of this study assessed

Aberrometry in the diagnosis and treatment of keratoconus
Russian Annals of OphthalmologyKeratoconus (KC) is a bilateral progressive disease that often begins in young adulthood. Advanced KC significantly impairs patients’ quality of life, making early detection of the condition a critical goal for specialists. Early identification of KC greatly influences both the treatment strategy and the outcomes.
