Implantable Medical Devices, Biomaterials, and the Foreign Body Response: A Surgical Perspective

Journal of Biomedical Materials Research Part A, Volume 113, Issue 9, September 2025.
ABSTRACT Implantable medical devices improve quality of life and reduce mortality by restoring the form and function of the human body. Their biomaterial surface components in contact with tissues are, however, susceptible to the host's foreign body response, which drives inflammation and implant fibrous encapsulation.

Effect of Photo‐Initiation Polymerization and Thermal‐Initiation Polymerization on the Reduction of Glistening in Hydrophobic Acrylic Intraocular Lens Materials

Macromolecular Chemistry and Physics, Volume 226, Issue 15, August 4, 2025.
Glistening is the condensation of water that forms within intraocular lens (IOL), which can degrade the patient's vision quality. Photo‐initiation and thermal‐initiation polymerization are widely used for the preparation of IOL materials. An interesting result is obtained that the glistening of photopolymerized IOL materials is much smaller than that ...

Presbyopia Correction in Lens Replacement Surgery: A Review

Clinical &Experimental Ophthalmology, Volume 53, Issue 6, Page 668-681, August 2025.
ABSTRACT Presbyopia affects approximately 1.8 billion individuals globally, posing significant challenges as life expectancy and near‐vision demands, particularly with mobile phone use, grow. Addressing presbyopia during lens replacement surgery has become a key focus for cataract surgeons, aiming to reduce dependence on corrective eyewear. This review
