Extensive mitral annulus calcifications are considered a contraindication for valve surgery. We describe the case of a 76-year-old female with severe mitral and aortic stenosis associated with extensive calcifications of the heart. The patient underwent an open mitroaortic valve replacement using transcatheter aortic valve implantation with an Edwards SAPIEN XT valve (Edwards Lifesciences Corp., Irvine, CA, USA) in the mitral position. The aortic valve was replaced using a stentless valve prosthesis (LivaNova SOLO; LivaNova PLC, London, UK)...

REVIEW
Kenneth J Hoffer, Giacomo Savini
An analysis of the studies published in the past 50 years reveals that the Haigis, Hoffer Q, and Holladay 2 formulas are the best options for intraocular lens power prediction in short eyes (<22 mm). In long eyes (>26 mm), the Barrett Universal II, Haigis (with optimized constants), Olsen, and SRK/T formulas provide the most accurate outcomes for intraocular lens power prediction.

Giacomo Savini, Kenneth J Hoffer, Piero Barboni, Domenico Schiano Lomoriello, Pietro Ducoli
PURPOSE: Given that a previous study found that corneal asphericity influences the refractive outcome of intraocular lens (IOL) power calculation by means of thin-lens formulas in eyes with spherical IOLs, the authors aimed to verify whether such influence can also be observed in eyes with aspherical IOLs. METHODS: In this retrospective comparative case series, IOL power was calculated with the Haigis, Hoffer Q, Holladay 1, and SRK/T formulas in two groups of eyes undergoing phacoemulsification and implantation of an aspherical IOL (Acrysof SN60WF; Alcon Laboratories, Inc...

Peripapillar and nerve head vessel density (VD) was measured in 10 patients affected by Dominant optic atrophy (DOA) using optical coherence tomography angiography (OCT-A) and compared to the measurements of 15 age- and gender-matched controls. DOA patients showed VD reduction, mostly in the temporal and inferotemporal peripapillary sectors, according to the preferential involvement of the papillomacular bundle. Despite poor best-corrected visual acuity (BCVA), OCT-A revealed good repeatability. VD correlated with functional (mean deviation of visual field and BCVA) and structural (retinal nerve fiber layer thickness) parameters and could be a non-invasive, quantitative tool for the monitoring of the disease and of the therapeutic approaches...

A case of monocular postoperative hemorrhagic occlusive retinal vasculitis (HORV) after uncomplicated bilateral cataract surgery is described. HORV is a severe syndrome that leads to painless visual loss after uncomplicated cataract surgery. The same surgical procedure was adopted in both eyes except for the use of intracameral vancomycin, which was injected only in the eye that developed HORV. Diffuse retinal ischemia with vascular sheathing and intraretinal hemorrhages were detected during the fourth postoperative day...
