Chitosan-Based Materials Featuring Multiscale Anisotropy for Wider Tissue Engineering Applications.

We designed graphene oxide composites with increased morphological and structural variability using fatty acid-coupled polysaccharide co-polymer as the continuous phase. The matrix was synthesized by N, O-acylation of chitosan with palmitic and lauric acid. The obtained co-polymer was crosslinked with genipin and composited with graphene oxide.

Autorefractometry after laser in situ keratomileusis.

Purpose: To correlate cycloplegic subjective refraction with cycloplegic autorefractometry in eyes that have had laser in situ keratomileusis (LASIK).

Setting: Vlemma Eye Institute, Athens, Greece.

Methods: Subjective refraction and autorefractometry under cycloplegia were performed in 73 eyes of 46 patients 1, 6, and 12 months after LASIK to correct myopia or myopic astigmatism.

Tear secretion following excimer laser in situ keratomileusis.

Purpose: To evaluate the effect of laser in situ keratomileusis (LASIK) on tear secretion.

Methods: A non-consecutive series of 42 eyes of 42 patients had LASIK for the correction of myopia and myopic astigmatism. The fellow eye served as a control.
