Clinical outcomes of a non-diffractive extended depth of focus intraocular lens in post-refractive eyes

 Collin Olevson, MD1 | John Berdahl, MD1,2 and Tanner Ferguson, MD1,2

1University of South Dakota Sanford School of Medicine, Vermillion, SD

2Vance Thompson Vision, Sioux Falls, SD

Introduction: Eyes with prior corneal refractive surgery (i.e laser-assisted in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK)) pose challenges during cataract surgery due to altered corneal curvature. The AcrySof IQ Vivity intraocular lens (IOL) is a non-diffractive extended depth-of-focus (EDOF) IOL designed to provide a broader range of vision. Limited data exists on its …

Visual Acuity and Quality of Life Results in a Randomized Trial of Topography-Guided with GIS-Software Versus Wavefront Optimized LASIK

Elise V.H. Meide, MD | Daniel C. Terveen, MD

Purpose: To compare post-operative visual acuity, refractive outcomes and patient-reported visual quality of life between topography-guided (TG) laser-assisted in situ keratomileusis (LASIK) with novel geographic imaging system (GIS) based software versus wavefront-optimized (WFO) LASIK. Main outcome measures included the rate of patients with uncorrected distance visual acuity (UDVA) of 20/16 or better 3 months post-operatively. Secondary and exploratory endpoints include best corrected visual acuity (BCVA), residual refractive error, low contrast visual acuity, …

Purpose: Pancreatic ductal adenocarcinomas (PDAC) are aggressive malignancies with poor prognoses. Emerging evidence suggests tissue hypercapnia (elevated CO2) promotes aggressive, treatment resistant tumor biology. End-tidal CO2 (ETCO2) offers a composite measure of ventilation, systemic perfusion, and tissue CO2 production. During curative-intent pancreaticoduodenectomy, we hypothesized that intraoperative ETCO2 could serve as a marker of tissue CO2 dyscapnia; both low levels indicating decreased circulatory reserves and high levels indicating tissue hypercapnia may result in worse outcomes.

Methods: We conducted a retrospective review (2017-2023) of 343 patients undergoing pancreaticoduodenectomy for PDAC. Intraoperative ETCO2 data …

Background

  • BRCA-Associated Ring Domain 1 (BARD1), a heterodimeric binding partner of the tumor suppressor BRCA1, plays an essential role in homologous recombination-mediated DNA repair. Mutations in BARD1 increase cancer susceptibility and result in a molecular phenotype that predicts sensitivity to poly (ADP-ribose) polymerase inhibition (PARPi), including Olaparib.
  • Several alternatively spliced isoforms of BARD1, including BARD1δ and BARD1φ, have also been implicated in tumor progression. These isoforms, characterized by deletion of exons 2-6 and 3-6, respectively, lack the RING domain required for BRCA1 interaction (Figure 1). 
  • Upregulation of BARD1 isoforms is associated with poor prognosis in several tumor types. However, the …

Use Of Preoperative Chlorhexidine Scrub In Prevention Of Groin Surgical Site Infections, Enoch Wong, Pranay Arora, Hunter Knight, Carissa Lucero, Edic Stephanian

North Texas GME Research Forum 2026

Background: Surgical site infections (SSIs) following groin exposure in vascular surgery are associated with significant morbidity, prolonged hospital length of stay, and increased healthcare costs. The groin is particularly susceptible to infection due to local skin flora and moisture, with studies demonstrating higher infection rates compared to other vascular operative sites (1). Despite standard perioperative infection prevention measures in the operating room, SSI rates following groin exposure remain unacceptably high. This quality improvement (QI) project aimed to reduce groin SSI rates through the implementation of a standardized preoperative chlorhexidine-based scrub protocol.

Methods: A single-center QI initiative was evaluated using a …
