Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

Advanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.

Ocular higher-order aberrations and visual performance [PDF]

, 2011
Since adaptive optics was first used to correct the monochromatic aberrations of the eye over a decade ago there has been considerable interest in correcting the ocular aberrations beyond defocus and astigmatism.

Patient‐reported outcomes and visual function after four refractive strategies in cataract surgery: A randomized controlled trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate patient‐reported outcome measures (PROMs) and visual function across four groups of public cataract patients: emmetropia, mini‐monovision, monovision with partial‐range of field (RoF) narrow intraocular lenses (IOLs) and patients implanted with partial‐RoF extended IOLs.

Premium Intraocular Lens Selection in Patients With Glaucoma: A Clinical Review

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Glaucoma frequently coexists with cataract, but glaucomatous functional loss, ocular‐surface disease, anatomical abnormalities, and treatment‐related refractive variability may reduce tolerance of premium intraocular lenses. This narrative review critically appraises evidence relevant to lens selection in glaucoma. Central visual‐field status,

The effect of cross-linking procedure on corneal wavefront aberrations in patients with keratoconus

Vojnosanitetski pregled, 2022
Background/Aim. Corneal cross-linking (CXL) treatment shows the best results in stabilizing the cornea and stopping the progress of the ectatic process. The aim of the study was to assess the impact of CXL on the keratoconus regarding higher-order aberrations (HOAs) and potential improvement of visual function. Methods.

The effect of pterygium surgery on wavefront analysis

Advanced Biomedical Research, 2014
Background: Pterygium is a common disorder of the ocular surface. It causes vision impairment -usually irregular type astigmatism- through different mechanisms. In addition, it is believed that surgical excision of the pterygium improves visual problems.

Monochromatic higher order aberrations in highly myopic eyes with Staphyloma

BMC Ophthalmology, 2021
Background Prevalence of high myopia is continuously increasing, thus, patients affected with staphyloma are abundant worldwide. Assessment of the quality of vision in these patients is mandatory for a proper clinical counselling, specially when ...

Corneal wavefront aberrations and subjective quality of vision after small incision lenticule extraction [PDF]

Acta Ophthalmologica, 2020
AbstractPurposeTo analyse in depth the associations between objectively measured corneal higher‐order aberrations (HOAs) and subjectively perceived visual quality after small incision lenticule extraction (SMILE) as quantified with the standardized and clinically validated quality of vision (QOV) questionnaire.MethodsThis cross‐sectional study included

Two‐Photon Fluorescence and Second‐Harmonic Generation Microscopy: Principles and Biomedical Applications

Journal of Biophotonics, Volume 19, Issue 10, October 2026.
Compared with single‐photon methods, TPM enables deep‐tissue imaging using near‐infrared light, with excitation confined to the focal plane, thereby reducing photodamage. SHG microscopy images noncentrosymmetric biological structures such as collagen and myosin without fluorescent labels, offering direct structural contrast.
