IOL power calculation in post-myopic LASIK eyesHan Chieh Yu
Intraocular lens (IOL) power calculation is less accurate in eyes with prior myopic LASIK. Dozens of IOL calculation formulas were designed for use in this kind of eyes, but their accuracy still lags behind those used in virgin eyes. This keynote contains the reported performance of formulas listed on iolcalc.ascrs.org and refractive results of our case series using no-history formulas.
Strategies for better toric IOL outcomes (Apr 2018)Han Chieh Yu
Residual astigmatism after cataract surgery makes negative impact on patients’ visual acuity and contrast sensitivity. Posterior corneal astigmatism contributes to total corneal astigmatism, acting as a vector, must be considered in the toric IOL calculation. The decision to advise toric IOL to patients should depend on the estimated post-operative total astigmatism, instead of the power of anterior corneal astigmatism. Getting consistent keratometry values from one of the many instruments is essential for IOL calculation. Toric calculator should also consider the variable ratios between the toricity of the IOL and corneal plane. Intra-operative tips to avoid IOL misalignment and reorientation to correct it are discussed. A small case series utilizing prior methods, with good post-operative refractive cylinder results, will be presented.
Strategies for better toric IOL outcomes (old version, Nov 2017)Han Chieh Yu
Pre-operative biometry, toric intraocular lens (IOL) implantation techniques, and rotational stability of the IOL are all important for great visual results. Targeting post-operative astigmatism less than 0.5 diopter (D) instead of looking for pre-operative anterior corneal astigmatism that is more than 0.75 D can lead to better refractive results.

Faro An Interactive Interface For Remote Administration Of Clinical Tests Bas...Kalle
A challenging goal today is the use of computer networking and advanced
monitoring technologies to extend human intellectual capabilities in medical decision making. Modern commercial eye trackers
are used in many of research fields, but the improvement of eye tracking technology, in terms of precision on the eye movements capture, has led to consider the eye tracker as a tool for vision analysis, so that its application in medical research, e.g. in ophthalmology, cognitive psychology and in neuroscience has grown considerably. The improvements of the human eye tracker interface become more and more important to allow medical doctors to increase their diagnosis capacity, especially if the interface allows them to remotely administer the clinical tests more appropriate for the problem at hand. In this paper, we propose a client/server eye tracking system that provides an interactive system for monitoring patients eye movements depending on the clinical test administered by the medical doctors. The system supports the retrieval of the gaze information and provides statistics to both medical research and disease diagnosis.

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.

Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

5. LIFELIKE DIRECT OPHTHALMOSCOPE
Device Handling
In order to examine a virtual patient on the Eyesi Direct simulator, trainees
need to look through the direct ophthalmoscope directed towards the patient
model head. They will then see the virtual patient and the ophthalmoscope
light cone. When moving the ophthalmoscope towards one of the virtual
patient’s eyes, the view of the retina is simulated in real-time.
DIOPTER SETTINGS AND LIGHT INTENSITY
Ophthalmoscope Controls
The Eyesi Direct ophthalmoscope handpiece features a built-in display and
provides the same controls as a real ophthalmoscope. Trainees can adjust
the ophthalmoscope’s diopter settings using the lens control. To change the
light intensity, they have to rotate the light control on the ophthalmoscope
handle.
LIGHT AND PATIENT’S EYES
Examination Setting
Other settings of the virtual direct ophthalmoscope, such as the diameter of
the light cone or color filters, can be controlled on the touch screen. Further,
the virtual patient’s eyes can be dilated. For changing the patients viewing

Simulator-based training allows for a standardized learning experience and ensures that all students
reach the same level of clinical proficiency. With a ready-to-go courseware, the Eyesi Direct simulator
can easily be integrated into educational programs.
STANDARDIZED CURRICULUM
Ready-to-Go Courseware
Eyesi Direct comes with a didactically structured curriculum, which has been designed to teach recogni-
tion of the most common pathologies within only a few hours. Students advance through the curriculum
independently and self-guided. Educators can lock or unlock courses as required.
CASE-BASED APPROACH
Database of Virtual Patients
The Eyesi Direct curriculum uses a case-based approach to teach diagnostic skills. The curriculum
consists of four courses, each containing several cases. Introductory, abstract cases are followed by
cases with pathologies in different stages. Patients of varying gender, age, and ethnicity present with
common pathologies, such as AMD, diabetic retinopathy, glaucoma, hypertensive retinopathy, optic
disc edema, or vascular occlusion.

Eyesi Direct
Feedback & Assessment
Eyesi Direct offers an interactive training environment that provides imme-
diate feedback on trainees’ performance. Educational guidance elements
support beginners in their learning process. Additional medical background
information deepens the understanding of anatomical and pathological
characteristics. A personal findings library, which is also accessible on the
VRmNet web portal, allows students to recap their learning matter.
PERFORMANCE MONITORING
Training Reports
After each case, Eyesi Direct presents trainees with a detailed performance
summary. The training system records various parameters relating to pro-
cedural and diagnostic abilities. The detailed evaluation allows trainees to
improve their skills systematically. Required minimum scores ensure that
trainees meet a certain skill level. By providing comprehensive training
reports, Eyesi Direct also allows educators to assess their students’ skill
acquisition.
9. EDUCATIONAL SUPPORT
Guidance Elements
Eyesi Direct features visual and auditive guidance to support beginners in their
learning process, for example, by highlighting anatomical findings on the ret-
ina. During the examination, a head-up display is visible in the ophthalmoscope
and shows information such as the name of detected anatomical features or
the duration of the examination. For better orientation, the head-up display
also provides a retina chart, which highlights the area already examined.
MEDICAL BACKGROUND
Findings Tiles
When a trainee detects a pathological finding in the more advanced cases,
it is highlighted on the retina, and a findings tile appears on the touch screen,
providing medical background information. All detected findings are stored in
the trainee’s personal findings library and are also accessible on the VRmNet
web portal for recap. The findings menu on the simulator can be used to start
cases associated with the specific finding.
DOCUMENTATION
Fundus Editor
To foster correct interpretation of the retina image and accurate documenta-
tion of findings, trainees need to find abstract objects and mark their location,
orientation, and size in the fundus editor of the introductory cases.
DIAGNOSTIC TRAINING
Multiple-Choice Forms
In the exam course, trainees have to find pathological signs without guidance
and specify their findings and diagnoses in multiple-choice forms, which are
then evaluated by the training system.
PERFORMANCE ASSESSMENT
Detailed Evaluation
At the end of each examination, trainees are presented with a detailed evalua-
tion of their performance. Scored parameters include the percentage of retina
examined, light exposure, completeness of pathological signs found, and the
accuracy of the diagnosis. Both trainees and educators also have access to
the accumulated training data on the VRmNet web portal.
