A randomized, fellow eye, comparison of keratometry, aberrometry, tear film, axial length and the anterior chamber depth after eye rubbing in non-keratoconic eyes

Eye and Vision, 2017
Background To investigate the effect of eye rubbing on keratometry (K), aberrometry, tear film break-up-time (TFBUT) and anterior chamber depth (ACD). Methods Volunteers without any corneal pathology or dry eyes were randomised to rubbing in one eye and ...

Development of a dry eye index as a new biomarker of dry eye disease

Ophthalmic and Physiological Optics, Volume 44, Issue 7, Page 1472-1483, November 2024.
Abstract Purpose To evaluate signs and symptoms in patients diagnosed with dry eye disease (DED), divided into dry eye (DE) groups, in order to find a new biomarker that allows an accurate diagnosis, management and classification of DED. Methods This cross‐sectional, observational study included 71 DED subjects.

Post cataract surgery refractive surprise due to intraocular lens mislabeling

Clinical Case Reports, Volume 12, Issue 7, July 2024.
Key Clinical Message If an intraocular lens (IOL) is incorrectly labeled, problems can arise for surgeons and patients. Precise biometry is important to accurately determine the IOL power and prevent the implantation of the wrong IOL. Labeling and verifying IOLs with accuracy is crucial to ensuring the best possible results of cataract surgery ...

The effect of multifocal contact lenses on the dynamic accommodation step response

Ophthalmic and Physiological Optics, Volume 44, Issue 2, Page 321-333, March 2024.
Abstract Purpose To measure the dynamic accommodation response (AR) to step stimuli with and without multifocal contact lenses (MFCLs), in emmetropes and myopes. Methods Twenty‐two adult subjects viewed alternating distance (0.25D) and near (3D) Maltese crosses placed in free space, through two contact lens types: single vision (SVCL) or centre ...
