The Aberrometric Effect of Corneal Plus Power Ring Distribution on Axial Length Growth in Myopic Children Undergoing Orthokeratology Treatment [PDF]
Background/Objectives: Myopia progression is strongly associated with axial length (AL) elongation, and orthokeratology (Ortho-K) lens design may influence treatment outcomes. This study has the aim to evaluate the impact of lens customization as optical

The classic equation for decomposing the wavefront aberrations of axis-symmetrical optical systems has the form, W ( h 0 , ρ , ϕ ) = ∑ j = 0 ∝ ∑ p = 0 ∝ ∑ m = 0 ∝ C 2 j + m 2 p + m m ( h 0 ...

High order aberration and straylight evaluation after cataract surgery with implantation of an aspheric, aberration correcting monofocal intraocular lens [PDF]
AIM:To evaluate the quality of vision in respect to high order aberrations and straylight perception after implantation of an aspheric, aberration correcting, monofocal intraocular lens (IOL).METHODS:Twenty-one patients (34 eyes) aged 50 to 83y underwent

Self calibration of sensorless adaptive optical microscopes [PDF]
We present a self-calibrating scheme for microscopes using model-based wavefront sensorless adaptive optics. Unlike previous methods, this scheme permits the calibration of system aberration modes without the need for a separate wavefront sensor or ...

The effects of implantable collamer lens implantation on higher order aberrations [PDF]
AIM: To evaluate the changes in higher order aberrations (HOAs) after implantable collamer lens (ICL; Staar Surgical, Nidau, Switzerland) implantation. METHODS: Totally 30 eyes of 18 patients with myopia were included in this study with an average age ...

Optical Behavior of an Enhanced Monofocal Intraocular Lens Compared with a Standard One
The aim of this work was to compare an enhanced monofocal (RayOne EMV RAO200E, Rayner) and standard monofocal (RayOne RAO600C Aspheric, Rayner) intraocular lenses (IOLs) for three nominal powers (+10.00 D, +20.00 D and +30.00 D) as a function of the ...
