Those lenses provide improved vision under low light conditions to the patient.Methods We will show first the influence of ocular aberrations on visual performance, and how do they change with pupil size. We will also show the way higher order aberrations affect the manifest refraction procedure. ...

VISUAL acuityASTIGMATISMHYPEROPIABackground: To evaluate accuracy of WASCA wavefront aberrometry (WA) refraction in comparison to manifest refraction (MR) in an older population awaiting cataract surgery. Methods: Prospectively, refractive errors of 130 eyes were determined by WA and MR. Mean age ...
Conclusions: Keratoconus should be suspected in patients with inter- eye differences in manifest refraction, especially when astigmatism exists. Any inter-eye asymmetry in keratometry or pachymetry values should be an indication for full keratoconus screening.Maleszka-Kurpiel, Magdalena...
REFRACTION (Optics)TOMOGRAPHYTOPOGRAPHYVISUAL acuityCATARACTPurpose: To compare variance of manifest refraction (MR) measurement and variance of refractive outcomes after keratorefractive lenticule extraction (KLEx) in the same cohort. Methods: This was a retrospective study of consecutive patients attending...

The cylinder axis on manifest refraction (MR) was significantly different from measured keratometry, so a second procedure was performed to align the cylinder axis of the IOL with the steep axis on MR. This repositioning procedure improved visual outcome to a final uncorrected vision of 20/25 (...
Near visual acuity, motility examination, slit lamp examination, dilated fundus examination, and cycloplegic refraction were recorded for each patient. Results Age range, was 3-41 years. Overall, near visual acuity was well preserved in all patients, with at least J3 acuity in the better eye. ...
