Severe Corneal Morphological Alterations after Excimer Laser Surface Ablation for a High Astigmatism

Case Reports in Ophthalmology, 2021
We report long-term alterations of anterior corneal stroma after excimer laser surface ablation for a high astigmatism. The patient claimed progressive visual loss in his right eye (RE) during the last 3 years after bilateral laser-assisted subepithelial

Biomimetic Cell Membrane‐Coated Scaffolds for Enhanced Tissue Regeneration

Advanced Materials, EarlyView.
This review examines the development and use of cell membrane‐coated scaffolds in tissue engineering. Bioinspired phospholipid and glycocalyx coatings enhance anti‐fouling, anti‐thrombogenic, and selective molecular recognition properties. Native cell membrane coatings further support cell‐specific interactions, immune modulation, and reduced bacterial

Organic Electrochemical Transistors Monolithically Integrated with Precise Micro‐Dispensing Enable High‐Performance Biosignals Amplification

Advanced Science, EarlyView.
This research showcases a micro‐dispensing strategy for integrating high‐performance organic electrochemical transistors (OECTs) and amplifiers onto flexible substrates. The method achieves precise material deposition, enabling fully micro‐dispensed OECT amplifiers with a record 1 MHz gain‐bandwidth product.

Analysis of best corrected visual acuity following corneal refractive surgery comparing low and standard predicted postoperative keratometry [PDF]

, 2018
BACKGROUND: It is a commonly held view in the ophthalmologic community that eyes with sufficiently low calculated postoperative corneal keratometry, less than 35 diopters, should not undergo corrective refractive laser surgery (CRLS) due to the increased
