A Cross-Sectional Study of Circadian Stimulus in Swedish Radiographers' Light Environment.

Timely light exposure is a vital aspect to achieve better sleep and well-being. As there are risks with a disturbed circadian rhythm and benefits with light settings that stimulate the rhythm, the circadian effective light, circadian stimulus (CS), for radiographers was examined. The aim of the study was to compare radiographers' light environment on the workstations, at a university hospital in Southern Sweden in the form of CS and relate that to recommendations published by the Swedish Environmental Protection Agency.

Naevi Characterization Using Hyperspectral Imaging: A Pilot Study.

Purpose: The prevalence of choroidal naevi is common and has been found to be up to 10%. Little is known regarding the optical properties of choroidal naevi. A novel hyperspectral eye fundus camera was used to investigate choroidal naevi's optical density spectra in the retina.

Ready for OR or not? Human reader supplements Eyesi scoring in cataract surgical skills assessment.

Purpose: To compare the internal computer-based scoring with human-based video scoring of cataract modules in the Eyesi virtual reality intraocular surgical simulator, a comparative case series was conducted at the Department of Clinical Sciences - Ophthalmology, Lund University, Skåne University Hospital, Malmö, Sweden.

Methods: Seven cataract surgeons and 17 medical students performed one video-recorded trial with each of the capsulorhexis, hydromaneuvers, and phacoemulsification divide-and-conquer modules. For each module, the simulator calculated an overall score for the performance ranging from 0 to 100.

Cataract surgeons outperform medical students in Eyesi virtual reality cataract surgery: evidence for construct validity.

Purpose: To investigate construct validity for modules hydromaneuvers and phaco on the Eyesi surgical simulator.

Methods: Seven cataract surgeons and 17 medical students performed capsulorhexis, hydromaneuvers, phaco, navigation, forceps, cracking and chopping modules in a standardized manner. Three trials were performed on each module (two on phaco) in the above order.

Stereoacuity and intraocular surgical skill: effect of stereoacuity level on virtual reality intraocular surgical performance.

Purpose: To evaluate the effect of stereoacuity on various intraocular surgical skills in inexperienced medical students using a virtual reality intraocular surgical simulator.

Setting: Department of Clinical Sciences, Malmö: Ophthalmology, Skåne University Hospital, Malmö, Sweden.

Design: Comparative case series.

Virtual reality cataract surgery training: learning curves and concurrent validity.

Purpose: To investigate initial learning curves on a virtual reality (VR) eye surgery simulator and whether achieved skills are transferable between tasks.

Methods: Thirty-five medical students were randomized to complete ten iterations on either the VR Caspulorhexis module (group A) or the Cataract navigation training module (group B) and then two iterations on the other module. Learning curves were compared between groups.
