Refractive error sensing from wavefront slopes.
The problem of measuring the objective refractive error with an aberrometer has shown to be more elusive than expected. Here, the formalism of differential geometry is applied to develop a theoretical framework of refractive error sensing. At each point of the pupil, the local refractive error is given by the wavefront curvature, which is a 2 × 2 symmetric matrix, whose elements are directly re...
متن کاملWavefront-optimized surface retreatments of refractive error following previous laser refractive surgery: a retrospective study.
BACKGROUND Retreatments are sometimes necessary to correct residual or induced refractive errors following refractive surgery. Many different combinations of primary treatment methods and retreatment techniques have been studied, however, few studies have investigated wavefront-optimized (WFO) technology for retreatment following primary refractive surgery. This study aimed to report the outcom...
متن کاملNear-infrared wavefront sensing
We discuss the advantages of wavefront sensing at near-infrared (IR) wavelengths with low-noise detector technologies that have recently become available. In this paper, we consider low order sensing with laser guide star (LGS) adaptive optics (AO) and high order sensing with natural guide star (NGS) AO. We then turn to the application of near-IR sensing with the W. M. Keck Observatory (WMKO) A...
متن کاملVisual outcome after correcting the refractive error of large pupil patients with wavefront-guided ablation
PURPOSE To investigate the efficacy and predictability of wavefront-guided laser in situ keratomileusis (LASIK) treatments using the iris registration (IR) technology for the correction of refractive errors in patients with large pupils. SETTING Horus Vision Correction Center, Alexandria, Egypt. METHODS Prospective noncomparative study including a total of 52 eyes of 30 consecutive laser re...
متن کاملOcular wavefront aberrations in the common marmoset Callithrix jacchus: Effects of age and refractive error
The common marmoset, Callithrix jacchus, is a primate model for emmetropization studies. The refractive development of the marmoset eye depends on visual experience, so knowledge of the optical quality of the eye is valuable. We report on the wavefront aberrations of the marmoset eye, measured with a clinical Hartmann-Shack aberrometer (COAS, AMO Wavefront Sciences). Aberrations were measured o...
