Artificial Lens Implant Migration
The shifting and or tilting of implanted artificial lens resulting in impaired vision.
Eye, Artificial
A ready-made or custom-made prosthesis of glass or plastic shaped and colored to resemble the anterior portion of a normal eye and used for cosmetic reasons. It is attached to the anterior portion of an orbital implant (ORBITAL IMPLANTS) which is placed in the socket of an enucleated or eviscerated eye. (From Dorland, 28th ed)
Lenses, Intraocular
Artificial implanted lenses.
Lenses
Pieces of glass or other transparent materials used for magnification or increased visual acuity.
Cataract Extraction
The removal of a cataractous CRYSTALLINE LENS from the eye.
Plasma Gases
Ionized gases, consisting of free electrons and ionized atoms or molecules which collectively behave differently than gas, solid, or liquid. Plasma gases are used in biomedical fields in surface modification; biological decontamination; dentistry (e.g., PLASMA ARC DENTAL CURING LIGHTS); and in other treatments (e.g., ARGON PLASMA COAGULATION).
Methylmethacrylate
The methyl ester of methacrylic acid. It polymerizes easily to form POLYMETHYL METHACRYLATE. It is used as a bone cement.
Atmospheric Pressure
The pressure at any point in an atmosphere due solely to the weight of the atmospheric gases above the point concerned.
Methylmethacrylates
The methyl esters of methacrylic acid that polymerize easily and are used as tissue cements, dental materials, and absorbent for biological substances.
Polymethyl Methacrylate
Polymerized methyl methacrylate monomers which are used as sheets, moulding, extrusion powders, surface coating resins, emulsion polymers, fibers, inks, and films (From International Labor Organization, 1983). This material is also used in tooth implants, bone cements, and hard corneal contact lenses.
Artificial Organs
Devices intended to replace non-functioning organs. They may be temporary or permanent. Since they are intended always to function as the natural organs they are replacing, they should be differentiated from PROSTHESES AND IMPLANTS and specific types of prostheses which, though also replacements for body parts, are frequently cosmetic (EYE, ARTIFICIAL) as well as functional (ARTIFICIAL LIMBS).
Epithelial Cells
Cells that line the inner and outer surfaces of the body by forming cellular layers (EPITHELIUM) or masses. Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.

Premium LensesPremium Lenses
As we age, the natural lens in the eye becomes less flexible, diminishing the eyes ability to switch its focus from one focal plane to another, a condition called presbyopia. Aging eyes may also develop cataracts, causing the lens to become cloudy or dark. The only method of correcting an established and progressing cataract is to undergo cataract surgery.. Once you have made the decision to undergo cataract surgery with your eye doctor you will have a series of decisions to make related to the type of artificial lens implant you will have. Up until recently everyone who had cataract surgery received a monofocal (standard) lens implant. This lens enabled for vision at only one distance, typically distances far away. With new innovations, lenses are now available that provide vision at multiple distances, allowing you to achieve the vision that best fits your needs. These lenses are referred to as premium lenses and come in various formats or types.. ...

Story Zacky the Yorkie 2014
A large, uniquely crafted microscope suspends from the ceiling of the high tech eye surgery suite at Cornell University. The veterinary ophthalmologist views the widely magnified diseased eye of his patient staring into binoculars. A few feet below he utilizes a deft touch to guide instruments that accomplish the miraculous task of restoring sight to a dog whose world had turned dark. Dr. Eric Ledbetter places a fine incision in the eye to allow ultrasound instruments to gently jiggle and then detach the cloudy cataract tissue before sucking it out through the same incision. He then squeezes a soft, rather fluid artificial intraocular lens into the space formerly occupied by the old lens. We inject the artificial lens and the capsule holds it in place. The artificial lens restores their vision to what it was before, said Ledbetter ...

When a cataract progresses to the point that it affects a persons ability to do normal everyday tasks, surgery may be needed. Cataract surgery involves removing the lens of the eye and replacing it with an artificial lens. The artificial lens requires no care and significantly improves vision. Cataract surgeries are typically out-patient procedures and allow the patient to return home that same day. If surgery is recommended Dr. Ruan can recommend highly skilled and qualified surgeons in the area and will provide follow-up care throughout the process to make sure there are absolutely no complications. ...

Cataract surgery is a technique used all over the world, with more than 15milion surgeries per year. The surgeon removes the opaque lens of the eye and replaces it transplanting an artificial lens. After the implant of the new photosensitive lens, patients must wear special glasses with UV filter that protect the eye for the first weeks after surgery, until the lens is customized.. Two weeks after surgery, the ophthalmologist measures vision, locates possible defects such as myopia, astigmatism or hypermetropia and consequently shapes the lens with light so that it adapts itself perfecty to the needs of the single patient. When implanted and personalized, the lens keeps on forever without stripping or substitutions. The result is an improvement in vision quality, with the possibility to see well and perform daily activities without wearing glasses. Although the advanced technology used is more expensive compared to the other lenses, this surgery, at Hospital San Giuseppe, will be offered to ...

How can you treat cataracts?
The only effective way of treating loss of vision is through surgery. Cataract surgery is very common. During the surgery the clouded lens are removed. The lens is what makes it possible for a person to focus on an object. When it is removed it can be replaced with an artificial lens which is called an IOL. At times this may not be used and glasses or lenses will make up for the lens that has been removed. Surgery may not be needed and it could be delayed for many months. Theres a significant

Topography & Autorefraction are done at the same time. Topography is a topographical map of your cornea. You may have this done if you have corneal trouble such as Keratoconus or if you have cataracts. Autorefraction provides an objective measurement of your refractive error (the strength glasses you wear).

Patente EP0442642B1 - Multi unit electrical apparatus with forced air cooling - Google PatentesPatente EP0442642B1 - Multi unit electrical apparatus with forced air cooling - Google Patentes
The use of one or more open loop dc centrifugal fans in a housing having this geometrical configuration provides an efficient and versatile method of cooling the units and power supply. The speed of an open loop centrifugal brushless dc fan (distinct from the fan described in EP 320 720) varies with back pressure and because the fans are located adjacent to the receiving means, as the impedance presented by the unit or units in the receiving means decreases, then so does the back pressure. This results in a decrease in fan speed and hence of fan noise. Apparatus with this type of housing and cooling arrangement would find use in a variety of different environments. In one configuration all the units are of the same type, for example magnetic disk drives. If one set of units is replaced with a second set having lower air flow impedance the overall air flow through the housing increases while the speed and noise of the fans automatically decreases. This would be especially useful in the case where ...

Open Loop Feedback Control of Material Properties Using a Pseudo-Circulatory SystemOpen Loop Feedback Control of Material Properties Using a Pseudo-Circulatory System
The 2014 International Consumer Electronics Show highlighted the strong interest in smart materials, and the industry believes that this market will hit $1.2 billion in 2014. Although the commercial sector s interest in these types of materials is relatively new, animals have been evolving some of the most advanced materials for millions of years in order to develop very effective features and adaptations. Examples include dolphin skin s anti-drag properties, the octopus camouflage properties, blood clots, and scar formation, to name a few.. APL researchers have designed hydrogel materials based on features exemplified by animals that can undergo large property changes in response to specific aqueous environments. For example, circulatory materials mimic octopus skin through dynamic self-assembly triggered by chemical, thermal, and mechanical stimuli. Hydrogels expand and contract in response to temperature, light, salt, humidity, and pH. Therefore, exposing them to hot or cold water, brightness ...

Boadicea - Control System
For position control, Boadicea uses a proportional-integral (P-I) control law. The advantage of an integrator is that it provides high gain at low frequencies and attenuates higher frequency noise. The biggest disadvantage the P-I control law is integral windup. Also, the servo response is slow because the valve does not open until after an error is established. To solve these shortcomings, Boadicea uses a feed-forward control law for a short time after a change in goal position. When the goal position changes, the P-I feedback controller is disabled, and the feed-forward controller operates open loop while the leg is moving. The feed-forward controller provides several advantages. First, because the integrator is disabled during the motion, it does not build up a large error. Second, the response time of the system is improved because the valve opens full bore without waiting for an error to accumulate. A third benefit is that the feedback controller only operates on smaller errors, so the ...

A-scan ultrasound biometry - WikipediaA-scan ultrasound biometry - Wikipedia
A-scan ultrasound biometry, commonly referred to as an A-scan (short for Amplitude scan), is routine type of diagnostic test used in optometry or ophthalmology. The A-scan provides data on the length of the eye, which is a major determinant in common sight disorders. The most common use of the A-scan is to determine eye length for calculation of intraocular lens power. Briefly, the total refractive power of the emmetropic eye is approximately 60. Of this power, the cornea provides roughly 40 diopters, and the crystalline lens 20 diopters. When a cataract is removed, the lens is replaced by an artificial lens implant. By measuring both the length of the eye (A-scan) and the power of the cornea (keratometry), a simple formula can be used to calculate the power of the intraocular lens needed. There are several different formulas that can be used depending on the actual characteristics of the eye. All the information here is not valid for medical purposes. The other major use of the A-scan is to ...

Aphakia - WikipediaAphakia - Wikipedia
Aphakia is the absence of the lens of the eye, due to surgical removal, a perforating wound or ulcer, or congenital anomaly. It causes a loss of accommodation, far sightedness (hyperopia), and a deep anterior chamber. Complications include detachment of the vitreous or retina, and glaucoma. Babies are rarely born with aphakia. Occurrence most often results from surgery to remove congenital cataract (clouding of the eyes lens, which can block light from entering the eye and focusing clearly). Congenital cataracts usually develop as a result of infection of the fetus or genetic reasons. It is often difficult to identify the exact cause of these cataracts, especially if only one eye is affected. People with aphakia have relatively small pupils and their pupils dilate to a lesser degree. Without the focusing power of the lens, the eye becomes very farsighted. This can be corrected by wearing glasses, contact lenses, or by implant of an artificial lens. Artificial lenses are described as ...

Americans Dont Understand Most Common Mid-Life Vision Problem | EmaxHealth
A recently completed Harris Interactive survey found an extraordinary lack of understanding of the mid- life vision condition called presbyopia. However, it also found that the vast majority of patients who underwent implantation of artificial lenses to correct the condition were overwhelmingly satisfied.. Presbyopia is a common eye condition, typically beginning around age 45, in which the natural lens of the eye becomes firmer and resists changing focus from far to near, making everyday tasks such as reading difficult.. The survey was conducted for the American Society of Cataract and Refractive Surgery Foundation (ASCRS) to gather a better understanding of peoples attitudes toward/knowledge of presbyopia and the available treatment options to correct this problem. The telephone survey polled 500 adults, aged 45+ from the general population, and 250 patients who had presbyopia- correcting artificial lenses implanted in their eyes.. Survey results showed that most adults in both sample ...

The International Ophthalmology Day is the recognition of the importance and effectiveness of the hard work of industry specialists, the improvement of international relations and the exchange of experience in this field.. Ophthalmologists started celebrating their professional holiday the International Day of Ophthalmology in 2004. The date of the International Day of Ophthalmology was August 8 - the birthday of the famous ophthalmologist Svyatoslav Fyodorov.. S.N. Fyodorov was not just a highly professional microsurgeon- ophthalmologist. Not abandoning medical practice, he was actively engaged in scientific research, and together with his colleague V. Zakharov created one of the worlds hardest artificial lens - Fyodorov-Zakharov model intraocular lenses.. The ophthalmologists job is to diagnose the condition of the eyes, identify certain abnormalities and prescribe appropriate treatment. The profession of an ...

Izon lens - Things You Didnt KnowIzon lens - Things You Didnt Know
Answers from doctors on izon lens. First: This is most commonly recommended in younger people with more extreme degrees of visual need beyond what lasik can easily accomplish. It involves the removal of the natural lens and replacement with an artificial lens of the correct power. This can be of great benefit to those with extreme eyeglass needs but it does carry some risk.

electromagnetism - Energy conservation in induced emf in open loop - Physics Stack Exchangeelectromagnetism - Energy conservation in induced emf in open loop - Physics Stack Exchange
If the loop is closed, the external agency will find that there is a force/torque on the magnets when they try to move/rotate them. They have to work against this force, and lose energy, which will finally be converted to electric energy in the circuit.. Now if the loop is kept open, the external agency will not feel this opposing force/torque when they try to move/rotate the magnets, and then no energy is lost.. We once did a similar experiment in our lab: A Stirling engine was connected to a generator through a belt. A large resistor was connected to the generator through a switch. When the switch is off, the circuit is open, and the engine runs smoothly at 300 RPM. EMF is generated by the generator, but no energy is lost in the circuit.. As soon as one turns the switch on, the resistor starts consuming energy, and the speed of the engine suddenly reduces to about 150 RPM, as now it has to apply much greater torque to rotate the generator. The power produced by the engine still remains equal. ...

AmplifiersAmplifiers
The ideal amplifier An ideal amplifier will pass the input signal through to the output undistorted but enlarged (gain set by user), with no delay. It will not be affected by the output impedance of the source (sensor). In addition the ideal amplifier will be able to drive any load: supply any current. No real amplifier is ideal, but an op amp can come close, at least with regard to gain at low frequency. The typical IC op amp has an open loop gain of 10^6 and a low frequency input impedance of about 10^12 ohms. Well see shortly how such high open loop gain is harnessed to create user-desired gains. Nonlinear gain: Consider log amplifiers and anti-log amplifiers: for enhancing or minimizing waveform spikes. Filtering by amplitude. In Simulink: the Deadzone operator. Off-the-shelf amplifiers In this chapter you will learn how to apply off-the-shelf amplifier ICs (integrated circuits) to problems in instrumentation. First will come ...

cataract surgical problem : Journal of Cataract & Refractive Surgerycataract surgical problem : Journal of Cataract & Refractive Surgery
This malpositioned lens needs to be surgically corrected since leaving a decentered lens, fixed dilated pupil, and eroding sutures is quite intolerable.. The IOL can be either replaced or repositioned and fixated to the adjacent structures. There seems to be no more capsular support (Figure 2). The lenses used 15 years ago were usually 13.0 mm and longer (since in 70% at least 1 loop was out of the bag), and still it was not enough for a stable fixation. Therefore, sulcus fixation alone is out of question.. Anterior chamber IOL is a reasonable option, especially the Artisan lens. However, pupilloplasty needs to be done first to ensure stable fixation and avoid diplopia.. My preference is to reposition and refixate the same IOL with minimal surgical intervention. This eye had a suprachoroidal hemorrhage in the past, probably as a result of a prolonged hypotony during the scleral fixation procedure. It is, therefore, at high risk to develop a second event if the eye is opened again. A closed ...

An all digital controlled current driver is used for each pulsed electromagnet (e.g., gradient coils) in a magnetic resonance imaging (MRI) system. Such an all digital current controller may be advantageously employed in either closed loop or open loop gradient coil control circuits. The elimination of analog components decreases cost, increases operating efficiency and improves operating characteristics of the MRI system.

Interpolation and extrapolation capabilities of non-linear behavioural models -ORCAInterpolation and extrapolation capabilities of non-linear behavioural models -ORCA
This paper demonstrates how the Poly Harmonic Distortion (PHD) modelling framework is effective in its ability to interpolate or extrapolate non-linear measured data and thereby improve the quality and speed of measurement systems. Fundamental interpolation was verified and demonstrated using a 7-coefficient model extracted from a sparse set of fundamental impedances (19 points). It was shown that a relatively low order polynomial was required to capture the second harmonic space. Interpolation accuracy was however increased by including more coefficients. Second harmonic extrapolation was carried out on measured data and shown to be accurate to an average confidence of 99% when 6 model coefficients were extracted on a 0.7 reflection coefficient circle and then used to predict data on a 1.0 reflection coefficient circle. Measurements were carried out using an open loop active load-pull system operating at a fundamental frequency of 9GHz, on a 0.5W 10×75μm GaAs PHEMT device.. ...

There is no problem with the conventional method. Shorting the + and -input pins and connecting them to VEE. In this case the input offset voltage is multiplied by the open loop gain and the output is fixed to High or Low. In the current datasheet the -input terminal is connected to VEE and the +input connected to a potential within the common mode input voltage range higher than VEE. This allows the output to be fixed and supports high impedance, making it recommended for all comparators. Connecting the +input pin to VCC will place it outside the common mode input range, but this shouldnt be a problem ...

Influence of stem geometry on the stability of polished tapered cemented femoral stems. - Nuffield Department of Orthopaedics,...
Polished, tapered stems are now widely used for cemented total hip replacement and many such designs have been introduced. However, a change in stem geometry may have a profound influence on stability. Stems with a wide, rectangular proximal section may be more stable than those which are narrower proximally. We examined the influence of proximal geometry on stability by comparing the two-year migration of the Exeter stem with a more recent design, the CPS-Plus, which has a wider shoulder and a more rectangular cross-section. The hypothesis was that these design features would increase rotational stability. Both stems subsided approximately 1 mm relative to the femur during the first two years after implantation. The Exeter stem was found to rotate into valgus (mean 0.2 degrees , sd 0.42 degrees ) and internally rotate (mean 1.28 degrees , sd 0.99 degrees ). The CPS-Plus showed no significant valgus rotation (mean 0.07 [correction] degrees, sd 0.29 [correction] degrees ) or internal rotation (mean -0.03
