Wavefront-Guided LASIK and Preoperative Higher Order Aberrations.
We read with interest the article by Kung and Manche in the April 2016 issue.1 In the first part of the article, they explained that most studies seemed to suggest that the wavefront-guided excimer laser procedures were slightly superior than wavefront-optimized approaches, particularly in patients with preoperative root mean square (RMS) of higher order aberrations (HOAs) less than 0.3 μm. How...
متن کاملEffect of wavefront optimized LASIK on higher order aberrations in myopic patients
OBJECTIVE To determine mean change induced in root mean square value of higher order aberrations in myopic patients undergoing wavefront optimized laser assisted in situ keratomileusis. METHODS This quasi experimental study was conducted at Armed Forces Institute of Ophthalmology, Rawalpindi, Pakistan from Jan 2014 to Dec 2014. Sixty eyes of 35 myopic patients were included in the study. All ...
متن کاملSpot size and quality of scanning laser correction of higher order wavefront aberrations.
PURPOSE To investigate the effect of laser spot size on the outcome of aberration correction with scanning laser corneal ablation. METHODS Numerical simulation of ablation outcome. RESULTS Correction of wavefront aberrations of Zernike modes from second to eighth order were simulated. Gaussian and top-hat beams of 0.6 to 2.0-mm full-width-half-maximum diameters were modeled. The fractional ...
متن کاملOcular higher-order wavefront aberrations in the Japanese adult population: the Yamagata Study (Funagata).
PURPOSE To investigate the relationship between age and ocular higher-order wavefront aberrations (HOAs) in an adult Japanese population, in addition to factors associated with HOA variations. METHODS In the Yamagata Study (Funagata) cohort, 227 adult Japanese participants (aged 37-86 years) underwent systemic and ophthalmologic examinations in 2012. Ocular, corneal, and internal HOAs were me...
متن کاملEffect of decentration of wavefront-corrected intraocular lenses on the higher-order aberrations of the eye.
OBJECTIVE To evaluate the theoretical effect of decentration of aspherical intraocular lenses (IOLs) and wavefront-corrected IOLs up to the sixth order on higher-order aberrations (HOAs) (third through sixth order) of the eye. METHODS An aspherical IOL with HOAs of fourth-order spherical aberrations only (-0.287 microm with a 6-mm pupil) and a wavefront-corrected IOL with HOAs of equal magnit...
