Temporal multiplexing with adaptive optics for simultaneous vision. [PDF]

, 2016
We present and test a methodology for generating simultaneous vision with a deformable mirror that changed shape at 50 Hz between two vergences: 0 D (far vision) and -2.5 D (near vision).

Observation of Visual Quality after Femtosecond Laser‐Assisted Cataract Surgery Combined with Trifocal Intraocular Lens Implantation

Computational and Mathematical Methods in Medicine, Volume 2022, Issue 1, 2022., 2022
Objective. This study is the first observation of Alcon’s PanOptix trifocal intraocular lens (IOL) implanted in 55 cataract patients with femtosecond laser‐assisted cataract surgery. Methods. Fifty‐five patients (63 eyes) with cataract were treated with femtosecond laser‐assisted cataract surgery combined with trifocal IOL implantation.

[Retracted] The Connection between High Myopia Patients and MiR‐708a or MiR‐148 Expression Levels in Aqueous Studies of Visual Acuity

BioMed Research International, Volume 2022, Issue 1, 2022., 2022
Myopia goes far beyond the inconvenience it brings. It is a prevailing and vision‐threatening eye disease, especially in Asia. Aberrantly expressed miR‐708a and miR‐148 are critical for accurate diagnosis, good prognosis, and precise response prediction of myopia.

Clinical and Aberrometric Evaluation of a New Monofocal IOL with Intermediate Vision Improvement

Journal of Ophthalmology, Volume 2022, Issue 1, 2022., 2022
Purpose. The aim of the study was to evaluate the visual outcomes, aberrometric results, and subjective and objective optical qualities 12 months after implantation of a new monofocal intraocular lens (Physiol IsoPure 1.2.3) in comparison with a standard monofocal intraocular lens (Tecnis PCB00).
