Tolerance to induced astigmatism of patients with trifocal or extended depth of focus intraocular lens implantation.

Background: Residual astigmatism is common after cataract surgery involving implantation of an intraocular lens, yet the tolerance of presbyopia-correcting intraocular lens to astigmatism of different magnitudes and axes is poorly understood. Here we compared visual acuity and quality in the presence of induced astigmatism after implantation of a trifocal or extended-depth-of-focus (EDOF) intraocular lens, the two widely used presbyopia-correcting intraocular lenses.

Methods: At least 3 months after implantation of a TFNT00 or ZXR00 intraocular lens, patients were analyzed by slit-lamp examination, non-contact tonometry, subjective refraction, iTrace aberrometry, and corneal topography.

Notes on distribution and ecology of Sharp (Coleoptera: Staphylinidae) in the Polish Carpathians.

Philonthus spinipes Sharp for the first time was described from East Asia (Sharp 1874). Presently the species occurs in the whole Palaearctic region. Original distribution of this species is difficult to define because it has obviously extended its distribution range westwards (Schillhammer 1999).
