Effect of tear film break-up on higher-order aberrations measured with wavefront sensor

Influence of cosmetically tinted soft contact lenses on higher-order wavefront aberrations and visual performance

“…This also may affect higher-order aberrations, because unstable tear film has been reported to influence optical aberration [28][29][30]. Static and dynamic changes of tear film in eyes wearing contact lenses, however, have not been clarified in detail.…”

Intensity Analysis of Hartmann-Shack Images in Cataractous, Keratoconic, and Normal Eyes to Investigate Light Scattering

“…6,7 It is also valuable clinically for diagnostic purposes in patients with keratoconus, 8 cataract, 9,10 or dry eye. 11,12 If wavefront aberration and light scattering could be measured simultaneously, evaluation of the optical quality of the eye would be more efficient and convenient than is the case when separate evaluation methods are used clinically.…”

The future role of wavefront-guided excimer ablation

“…Fluctuation due to accommodation [37], tear film changes [21] and potential misalignment of the measurement system [32] might lead to high intra-individual variations. Furthermore, shifts in pupil center location from when aberrations are measured preoperatively (over a dilated pupil) to when they are corrected surgically (over a natural pupil) led to the induction of HOA [44].…”
