Extended Depth-of-Field Intraocular Lenses: An Update
Asia - Pacific Journal of Ophthalmology, 2020 Extended depth-of-focus (EDOF) is a new intraocular lens (IOL) technology in the treatment of presbyopia. In contrast to multifocal (MF) IOLs, EDOF lenses create a single elongated focal point, rather than several foci, to enhance depth of focus. In this

THE M31 PIXEL LENSING PLAN CAMPAIGN: MACHO LENSING AND SELF-LENSING SIGNALS [PDF]
The Astrophysical Journal, 2014 We present the final analysis of the observational campaign carried out by the PLAN (Pixel Lensing Andromeda) collaboration to detect a dark matter signal in form of MACHOs through the microlensing effect. The campaign consists of about 1 month/year observations carried out over 4 years (2007-2010) at the 1.5 m Cassini telescope in Loiano (Astronomical
