This document summarizes the experience of a private practice in Denmark using the Mediphacos MF-R2 intraocular lens (IOL). It found that the MF-R2 IOL had the least resistance during injection compared to other IOLs and could safely be injected through a 1.8 mm incision. Out of 89 eyes that received the MF-R2 IOL, most had good visual acuity outcomes with few complications. However, the author notes a concern about long-term stability of the thin IOL design and potential for capsule contraction and IOL movement over time. A new study will directly compare outcomes of the MF-R2 IOL to the Alcon AcrySof

Wide angle viewing field systems in vr surgerySamuel Ponraj
Wide angle viewing systems provide panoramic views of the retina during vitreous surgery. There are contact and non-contact systems. Contact systems include vitreous panfundoscopes, contact wide field lenses, advanced visual instrument systems, and reinverting operating lens systems. These provide good image resolution but require an inverter due to the inverted image and have risks of corneal trauma. Non-contact systems like the BIOM and Resight provide upright images without inversion but have poorer image quality. Newer non-contact systems aim to provide wide fields of view with upright high resolution images.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

alcohol, or a
10% bleach solution (by volume). Do not immerse.
NOTE: Excess solution entering the assembly could damage internal components. Use
caution to
ensure cloth is not saturated with solution.
Do not sterilize the 719 Series Power Handle

9. PanOptic 11820.
The PanOptic™ Ophthalmoscope
Transparency of the cornea, lens and vitreous humor permits the
practitioner to directly view arteries, veins, and the optic nerve of the retina.
Direct observation of the structures of the fundus through a PanOptic Ophthalmoscope
may show disease of the eye itself or may
reveal abnormalities indicative of disease elsewhere in the body.
Among the most important of these are vascular changes due to diabetes or hypertension
and swelling of the optic nerve head due to
papilledema or optic neuritis. In this sense, the eye serves as a window through which
many valuable clinical evaluations may be made.
When a preliminary diagnosis of an imminently dangerous eye condition, such as acute
(angle-closure) glaucoma or retinal detachment, is made by the examiner, prompt referral
to an eye specialist
may prevent irreversible damage. Or, when distressing but less
urgent conditions, such as visual impairment due to cataract or vitreous floaters, are
recognized, the patient can be reassured and referred.

Apertures and Filters
There is a wide range of practical apertures and filters to select
from: small spot, large spot, micro spot, slit aperture, red-free filter,
cobalt blue filter (optional), and half-moon aperture (optional).
11. 1. Small Aperture: Provides easy view of the fundus
through an undilated pupil. Always start the
examination with this aperture and proceed to micro
aperture if pupil is particularly small and/or sensitive to
light. This position is the “Home” position on the
aperture dial and is denoted by the green marking.
2. Large Aperture: Standard aperture for dilated pupil
examination of the eye.
3. Micro Spot Aperture: Allows easy entry in very small,
undilated pupils.
4. Slit Aperture (Models 11810, 11820 only): Helpful in
determining various elevations of lesions, particularly
tumors and edematous discs.
12. 5. Red-Free Filter (Model 11810, 11820 only): This filter
excludes red rays from the examination field: this is
superior to ordinary light in viewing slight alterations
in vessels, minute retinal hemorrhages, ill-defined exudates
and obscure changes in the macula. The nerve fibers become
visible and the observer may note the disappearance of such
fibers, as in optic nerve atrophy. The background appears gray,
the disc appears white, the macula appears yellow, the fundus
reflex is intense and the vessels appear almost black. This filter
is also used to help distinguish veins from arteries; veins stay relatively blue, but
oxygenated arterial blood makes arteries
appear blacker. This greater contrast makes differentiation
easier for the examiner.
6. Cobalt Blue Filter (Model 11820 only): In conjunction
with fluorescein dye applied topically to the cornea
and an add-on magnifying lens (included), this filter is
helpful in detecting corneal abrasions and foreign
bodies. In this way, it can be used as a surrogate to a
Woods Light.
7. Half-Moon Aperture (11810 Only): Provides a
combination of depth perception and field-of view.
13. Attaching and Use of Corneal Viewing Lens for PanOptic Ophthalmoscope
1. Remove the patient eyecup and insert the Corneal Viewing Lens into the patient’s
side of the instrument. Push and twist in one motion until you feel the two “lock”
together. Verify that the line on the lens housing is aligned with the top seam of
the PanOptic instrument. Note: the lens itself is intentionally tilted on an angle
within its housing. This is done to prevent glare from interfering with the exam.
2. When using the Corneal Viewing Lens, no contact is made between the scope and
the patient. Start with the focus wheel set to 0 (zero) and place the scope about 6”
from the patient’s eye. With the light shining on the cornea and looking through
the scope, adjust the focus wheel into the green (plus) diopters while moving the
instrument slightly toward (closer) or further away (out) from the patient until a
comfortable working distance and magnification of the cornea is achieved.
14. Cleaning and Repair Instructions
Cleaning and repairs (with exception of the lamp replacement)
beyond what is specified in the “general cleaning instructions” section
should be performed at the factory.
General Cleaning Instructions
NOTE: Excess solution entering the optical assembly could damage
internal components. Use caution to ensure cloth is not saturated
with solution.
This is a precision optical instrument. Please follow these specific
cleaning requirements:
• Do not use any solvent based cleaners on the lenses. Use only
the supplied cleaning cloth on the lenses.
• The PanOptic Ophthalmoscope is Non-sterilizable.
• Disinfect housing using soft cloth moistened with alcohol.
• Clean the Patient Eyecup by any of the following methods:
1. Soft cloth/cotton swab moistened with alcohol.
2. Soaking in gluteraldehyde based solutions (i.e. Cidex
OPA).
NOTE: For disinfection time / procedure requirements it is
recommneded that you follow the directions of the
specific brand you are using.
3. Autoclaving.
• Do not use acetone based products or other harsh chemicals.
No other preventative maintenance is necessary for this product.
17. iExaminer Adapter
• The new Welch Allyn iExaminer turns the PanOptic
Ophthalmoscope into a mobile digital imaging device allowing
you to view and take pictures of the eye like you've never
done before. The adapter aligns the optical access of the
PanOptic Ophthalmoscope to the visual axis of the iPhone 4 or
4S camera to capture high resolution (5/ 8 megapixel*)
pictures of the fundus and retinal nerve. The iExaminer App
then allows you to store the pictures to a patient file or email
and print them. And, because the PanOptic Ophthalmoscope
provides a 5x larger view of the fundus than a standard Welch
Allyn ophthalmoscope and 25° field-of-view without having to
dilate the pupil, the fundus imaging can happen anytime,
anywhere. - See more at:
