Purpose: To find out the incidence of intraocular lens (IOL) optic opacification in a suspect IOL.
Methods: Retrospective review of patients' notes 3-4 years postimplant.
Results: In all, 56 IOLs showed signs of opacification, resulting in reduced vision out of 181 lenses traced.
Conclusion: Certain hydrophilic acrylic IOLs like the model in question (SC60B-0UV) show opacification of the IOL, which may impair the vision of pseudophakic patients. However, not all lenses of this variety exhibit this cloudiness. Factors affecting this phenomenon are not yet completely clear but may include changes in the UV absorbant material incorporated in the lens substance itself. We report a series of patients who had received this lens and experienced loss of vision due to opacification of the IOL. In a follow-up ranging from 1 to 4 years postoperatively, a higher incidence of postoperative opacification of this lens emerges, after comparison with existing literature. IOL exchange in such patients is the only option. However, this mode of treatment should not be offered lightly as results may be guarded at best even in the face of a technically satisfactory procedure.

Amide modified cellulose-g-poly acrylic acid as a supple superabsorbent for water retention and soil conditioner.

Acrylamide has high hydrophilic properties due to the presence of hydrophilic amide functional groups and is frequently used to synthesize superabsorbents. However, the toxic and carcinogenic properties of acrylamide have caused environmental concerns. The main goal of this paper is the synthesis of superabsorbent with high water absorption from biodegradable and biocompatible cellulose polymer containing amide groups in the backbone of it instead of grafting harmful acrylamide monomers to cellulose.

In this study, new monolithic poly(9-anthracenylmethyl methacrylate-co-trimethylolpropane trimethacrylate (TRIM) columns, referred as ANM monoliths were prepared, for the first time, and were used for the separation media for biomolecules and proteomics analysis by nano-liquid chromatography (nano-LC). Monolithic columns were prepared by in situ polymerization of 9-anthracenylmethyl methacrylate (ANM) and trimethylolpropane trimethacrylate (TRIM) in a fused silica capillary column of 100 µm ID. Polymerization solution was optimized in relation to monomer and porogenic solvent.

The synthesis of poly(N-isopropyl acrylamide) (pNIPA)-based polymers via the surfactant-free precipitation polymerization (SFPP) method produced thermosensitive nanospheres with a range of distinctive physicochemical properties. Nano- and microparticles were generated using various initiators, significantly influencing particle characteristics, including the hydrodynamic diameter (D), which varied from 87.7 nm to 1618.

This research investigated the selected properties of nanocellulose films intended to serve as protective patches on fissured surfaces of wooden artefacts. The effects of their plasticisation with glycerol and functionalisation with selected silanes ((3-Glycidyloxypropyl)trimethoxysilane, and Methyltrimethoxysilane) were also determined. The obtained pure cellulose nanopapers (CNPs) had a homogeneous and compact structure but were very brittle, stiff, and wavy.

The article is devoted to the creation of enzymatic nanoreactors based on polystyrene-block-poly(acrylic acid) (PS-b-PAA) copolymers containing bioscavengers capable of neutralizing toxic esters both in the body and in the environment. Block copolymers of different amphiphilicity, hydrophilicity and molecular weights were synthesized and characterized using gel permeation chromatography, NMR and UV spectroscopy. Polymeric nanocontainers in the absence and presence of human butyrylcholinesterase were made by film hydration and characterized by dynamic light scattering and microscopy methods.
