Current approaches to the intraocular correction of postoperative aphakia after corneal refractive surgery (a review)

Oftalʹmologiâ, 2015
Cataract surgery after radial keratotomy (RK) represents many challenges as many patients who had RK are now developing visually significant cataracts. Currently, cataract surgery is not only the exchange of opaque lens but a refractive procedure as well.

Near visual function measured with a novel tablet application in patients with astigmatism

Clinical and Experimental Optometry, EarlyView., 2020
Clinical relevance While the clinical focus of performance metrics is traditionally based on visual acuity, research from the field of visual impairment has demonstrated that metrics such as reading speed and critical print size correlate much more strongly with subjective patient reported outcomes and assessed ability in real‐world tasks.

Silicone Breast Implants as a Model System for Understanding Polymer Permeation in Soft Materials In Vivo

Advanced Healthcare Materials, EarlyView.
Silicone breast implants are presented as a model system for understanding polymer permeation in vivo. Rather than representing material failure, “gel bleed” emerges from solution–diffusion transport‐mediated. By integrating polymer architecture, physicochemical transport, and biointerfacial processes, this review provides a unified framework that ...

Perioperative assessment for refractive cataract surgery

, 2018
As cataract surgery has evolved into lens-based refractive surgery, expectations for refractive outcomes continue to increase. During the past decade, advancements in technology have provided new ways to measure the cornea in preparation for cataract ...

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

Advanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...

Factors Governing Photodynamic Cross-Linking of Ocular Coat [PDF]

, 2011
This thesis addresses the challenge of minimizing toxicity of therapeutic protein-protein cross-linking of the cornea and sclera. Protein-protein cross-links include disulfide bonds, enzymatic cross-links and non-enzymatic cross-links.
