Topcon reveals the additions to the latest technology

ophthalmic equipment from TopconTopcon is one of the companies engaged in the development of ophthalmic equipment. It has boosted its line of optical equipment kit with the addition of recently introduced technology. The company has also involved the Internet with the launch of i-clarity, which is a cloud based service, for storage of big data.

Smart functions, easiness in use and compactness have been the main attributes of all the ophthalmic equipment in the range of devices that was demonstrated by Topcon at the British Contact Lens Association (BCLA).

The keratometers in KR-800S series and KR-800 range have been incorporated with the touchscreen technology. Besides, they can now provide increased stability in readings due to the incorporation of rotary prism technology as well. The CA200F topographer has been enhanced with pupillometry and fluometry. Topcon has already claimed the topographer allows in-situ vision of the lenses under fluorescein. Inclusion of a fresh user interface also benefits the device, which now has intuitive workflow that allows users to assess surgery patients, especially those who have undergone post-refractive operation, quickly and easily.

Topcon also claims that it has made its newest optical coherence tomographer, 3D OCT1 Maestro, more flexible, faster, smaller and lighter. It is loaded with an array of beneficial attributes such as the ability to perform 50,000A scans every second. Besides, topography, macular measurement, optic nerve measurement, colour fundus camera, capture of OCT, auto alignment and  focus of OCT can be done by the ophthalmic equipment in one single scan.

On the other hand, TRK-2P is a 4-in-1 ophthalmic equipment that offers pachymetry, non-contact tonometry, keratometry and refraction. Topcon said that the combination of optical instruments is unusual, and therefore, described it as unique. The microscope with the SP-1P mounted at the centre and with the ability to panoramic imaging can be used for a number of purposes such as the analysis of the cells of corneal endothelium. An auto alignment system and touch panel are some of its other attributes that deserve mention.

Topcon found BCLA fit for the announcement of the Cloud edition of its practice management setup named i-Clarity too. It allows storage of data into the virtual Cloud. Thus, the security against data theft and loss of data due to malfunction of computer has been enhanced. Besides, it also eliminates the limitation of storage space.

Topcon Medical Systems (TMS) is one of the leading developers of suppliers of ophthalmic equipment. It is based in Oakland, New Jersey. The company has continued to develop technologically advanced equipment that realise the seemingly impossible ideas. It has been involved in research and development for more than 4 decades. It has a diverse product line and is one of the biggest producers of precision instruments that are used for delivery, surgical, refractive, diagnostic and imaging purposes. Its products are designed with keen consideration for practitioners’ need and are supported by dedicated service specialists. The fact that Topcon Medical Systems is a fully owned subsidiary of Topcon Corporation, Japan is an advantage and adds value to an already respected company.

Novartis to produce smart contact lens

Novartis to produce smart contact lensA new idea of integrating technology into healthcare and facilitating personal health monitoring has struck the business developers at Novartis. The Swiss pharmaceutical company has approached Google with the idea and proposed that the American organisation develop the product. In fact, an agreement to develop smart contact lens has already been struck between Google and Novartis. The lenses will help aging people restore the ability of their eyes to focus and enable patients of diabetes track the level of sugar in their blood. Separate pairs of lenses are expected to be made for tracking blood-sugar in diabetics and restoration of focus of aging people.

The pair of lenses for diabetics will be capable of measuring glucose in the tear and sending the data wirelessly to a synchronised mobile device, according to Novartis. The technology has the potential to change the way diabetics live, pricking their fingers about 10 times daily in order to check the level of sugar their blood. Success in this venture will enable Novartis gain an edge in the global market of blood-sugar tracking, which is expected to be greater than $12 billion in worth by 2017, according to GlobalData. About 382 million people are afflicted by diabetes worldwide. The figures alone reveal the size of the market.

The second approach of Novartis is aimed at presbyopia, which is the condition of trouble in focusing on closer objects. It occurs typically with aging. The company hopes that Google will be able to develop the contact lens technology for it that will help people restore their ability to focus. The technology has been exemplified with autofocus technology in contemporary cameras. The contact lens will feature non-invasive microchips, sensors and other miniature electronics embedded to them. Undoubtedly, the idea demands very high level innovation, precision, technological infrastructure and research.

The deal encompasses that Alcon, which is the eye care unit of Novartis, will further develop the contact lens technology with Google, according to the development team at the company. Whenever it becomes reality, it is going to be a completely commercial product. The financial details pertaining to the deal have not been discussed by either company. The alliance of Google and Novartis, the 2 prominent names in their respective domains, is one of the results of exploration of technology to integrated technology into healthcare sector. Medical science has been active adopter of cotemporary technologies for the facilitation of convenient and easy health and fitness monitoring.

The development of such technologically advanced devices will lower the cost of chronic disease management for the patients. In addition to pharmaceutical companies, computing technology organisations such as Google, Samsung Electronics, Apple, etc. are trying to integrated health-care applications with wearable devices. According to Joe Jimenez, the contact lens for diabetics and those for poor focus can be expected to be released within next 5 years. The coming together of high technology and biology is indeed an exciting combination. The pace at which technology develops indicates that it will contribute much more to the medical science industry in the future.

New developments in the world of ophthalmology

nidek-logoNidek Inc. is one of the major global leaders in the manufacturing, designing, and distribution of the ophthalmic equipment. It announces with pleasure the FDA clearance of RS-3000 Advance. The OCT system that incorporates Scanning Laser Ophthalmoscope has been designed to carry out a comprehensive examination of choroid and retina. The ophthalmic equipment offers exquisite and minute details of the choroidal and retinal microstructures for assistance in a clinical diagnosis.

The features in this ophthalmic equipment include choroidal mode and this enables a detailed evaluation and examination of choroids. The minute structures inside the retina would require a broad area for scanning. The broad area scan enables a satisfactory coverage of retinal structures. The involuntary movements of the eye and microsaccades are adjusted by means of Tracing HD functionality at the time of macular line scanning. The function is carried out in order to ensure an accurate or perfect alignment that should be up to one hundred and twenty macular line scanned images to offer enhanced averaging of images. The cyclotorsion is compensated by a function for automatic registration at the time of image acquisition. This improves or enhances the quality or status of the follow up information.

Scanning at high speed, which is about 53000 A Scans per second, during acquisition along with tracing raises the accuracy. It also offers 2 additional scanning modes of higher sensitivity with tracing which should enable imaging by means of media opacities.  The device enables a seamless integration with most of the EMR systems that make use of NAVIS-EX, which is the software that files images. This networks the ophthalmic equipment along with other imaging devices by NIDEK.

NIDEK’s president, Motoki Ozawa, has maintained that they have been highly pleased to get the clearance. He expressed confidence as he stated that the quality or status of the tools for diagnosis, which are used in imaging and which assist the doctors in their diagnosis of ocular troubles and diseases, are reflected by the results.

This new and improved ophthalmic equipment has been functioned with OCT sensitivity that is selectable. The device enables the selection of OCT sensitivity between regular, fine, and ultra fine sensitivities that are based upon ocular pathology. This allows high definition image capturing at very high speeds. The TET functionality enables accurate capturing of images. This functionality ensures an accurate capturing of images by using fundus data from the SLO image. The tracing of ocular cyclotorsion is done through the feature of torsion correction added to tracing function.

The multifunctional follow-up in this ophthalmic equipment allows for the analysis of the complete information that is obtained with OCT along with an elaborate observation of the chronological change in the status and thickness of retina. The functionality has been included in order to display the pathological progression with time. The user selects two images that are displayed by comparison mode. The device also enables the customization of the structure of reports. This apart, the data collected from the individual reports of all the scan patterns can be drawn into a summary to form one single report in order to avoid the printing of multiple pages.

Go through the ADHD symptoms

Children that have an ADHD disorder are observed as either acting bad or as bad students. The symptoms, however, are a little different when the adults are affected by the disorder. Our discussion for the day shall be restricted to the ADHD symptoms and the way in which they affect the regular activities of the sufferer.

Focussing difficulty

The adults who have ADHD find particular difficulty to concentrate on projects as it is hard for them to focus for long. The suffering people are easily distracted by those things that do not, normally, distract others. They are more enticed by other things when they are trying to concentrate on one. They get easily bored and cannot focus when others are speaking. This is often interpreted as rudeness. The patients can opt for the medications as Adderall or the Adderall alternative.


Patients of ADHD are characterized by forgetfulness in their behaviour. They cannot keep themselves and their belongings organized and are always in the middle of chaos. Skills as prioritization and note taking, or organizing the living place or some information, are often found to be lacking.

Hyper focus

People suffering from the ADHD disorder tend to become absorbed in things they take delight in. This can be read as the method in which they calm their brains from chaotic thoughts. This often causes procrastination.


This is another trait in the character of an ADHD sufferer. They cannot inhibit their behaviours and thus act negatively. Such patients can interrupt the people when they are talking, often sounding as being insulting. The sufferers can take Adderall alternative to relieve the symptoms.

Phoroptor: A brief introduction

Phoropter_Ezer_EDR_5200_Ophthalmic_equipmentPhoroptor is one of the many instruments that are used by an optometrist at the time of examining an eye. The refractive error of a patient can be measured by this instrument, which then helps in determining the type of lens suitable for the patient.

This machine is used only when the doctor figures out that you are having such problem like astigmatism or nearsightedness. The device comes with a lens- series and when using it, the optometrist will be switching these lenses and will be doing some necessary settings. The optometrist, meanwhile, will be getting feedback from his patient that will help him in providing the best possible vision.

The device’s main function is in determining the way in which the lens is required to be curved. This is referred as refraction and explains why phoroptor involves the process of switching lenses.

At the time of using this machine, the patient is asked to sit comfortably behind this instrument and look through it. The machine places a chart at a distance of around 40cm from the eye of the patient. After the patient takes his seat, the doctor starts changing the lenses as he receives the patient’s feedback. The patient is required to answer the various questions thrown to him by the doctor whenever he changes the lens.

Phoroptor can be also used with other instruments as well. These include retinoscope and automated refractor. Other than that, phoroptor is used in determining the eye’s normal resting position along with the accommodative posture, amplitude, horizontal and vertical vergences. Continue reading →


Speed and accuracy of ophthalmic equipment are improving as days pass. The development and enhancement of autorefractors is going through an equally good phase. In fact, a trend seems to have started in which new manufacturers are entering the domain and new simple, portable and affordable instruments are being released in the market.

Optometrists agree that lone autorefractors as well as combination of autorefractor and keratometer have become much faster, more accurate and easier to operate.

According to Cliff Wright, auto-alignment, high-speed printing capability and the accuracy in results are some of the features of modern autorefractors that drew his attention. Cliff Wright is a private practitioner in Berkley, California. He emphasised the simplicity of these modern ophthalmic instruments by saying that it takes only minutes to train an assistant to operate these equipment.

Today, he is able to follow his patients post their surgeries much conveniently. He appreciates the accuracy and user-friendliness of the devices, which have excellent fogging capability. The autorefractor has almost become a mainstay device at his clinic and he expresses only wonder on how frequently it used by him nowadays. Continue reading →

Getting to Know Medical Rubber

There are a lot of medical equipment and devices that are made for rubber. Rubber is ideal for medical purposes as these are odorless, easy to clean, and durable. There is a medical equipment or device for every medical condition or illness.

Vaginal Douche Sprays

The vaginal douche spray is sterilized for about four hours before it is used. In case of enema, it should be filled with lukewarm water. It is advised to use Vaseline as lubricant for the nozzle. This will then be inserted to the vagina or the anus before the rubber bulb is squeezed. This may be done for up to three times. After use, the vaginal douche spray and all its components should be washed with warm water. People need to make sure that their vaginal douche spray is made of nothing less than surgical grade rubber. This will ensure efficiency and durability. Vaginal douche sprays that are made of surgical grade rubber are very easy to use. These are durable, efficient, reliable, and it comes at a reasonable price.

Ice Bags

Rubber ice bags are very handy in a lot of different situations especially for pain and swelling relief. It mostly comes in an oval shape. Ice bags are waterproof.

Rectal Syringes

Rectal syringes should always be cleaned by flushing water in and out of it first before use. Then, the pipe should be inserted to the bulb. Squeeze the bulb right after to get rid of air. Slowly fill the bulb with water or enema mixture. Then, make sure to lubricate its tip for a more comfortable use. Insert the pipe to the rectum gently. Squeeze the bulb gently. This will release the water or solution. Disassemble the rectal syringe then clean all components thoroughly. Use mild soap and lukewarm water for cleaning. Shake with water and air-dry before storing in a cool, dry place.

Stomach Tubes

Stomach tubes are used for people who cannot eat normally because of swallowing difficulties. These are inserted into the stomach through the patient’s abdominal skin. The patient is then fed through a tube which goes straight to the stomach. This way, the food does not have to go through the mouth and the patient’s esophagus anymore. Patients who will have a stomach tube insertion are asked not to eat for about eight hours. The patient will then be sedated and given pain reliever and antibiotics through his or her vein. Local anesthesia will also be applied.


Tourniquets are used to control circulation of blood through veins and arteries. It is used just for a short period of time. Some tourniquets are self-applied, automatic, and contoured and wide cuffs. This is usually used to control and stop bleeding.

Measuring refractive errors is not easy and it is always better when one gets some equipment that smoothly conducts the process. The equipment that has been most successful in doing this is autorefractor. It measures the problems in patient’s eye and prescribes the treatment required. Eye doctors find this equipment to be a very helpful and use it while studying the patient’s eye. The technique is easy, smooth and this does not give any pain.


This method does not take much time and the equipment aims at making the process simple for both doctors and patients. The doctor will make the patient sit in front of device and the chins of patient must rest of device’s chin rest. The picture being viewed to the patient should be placed over pateint’s retina and autorefractor studies the visual activity of eye and prints the reading. After this process is finished another examination is done where the patient will look at an image and tell whether it is clear or fuzzy. After optometrist gets clear readings by using different lenses they decide the prescription strength. This device will conduct whole readings on its own and does not require any verbal response of patient. Even the eminent personalities in this field of eye care consider autorefractor to be the best.

Portable Autorefractors

Portable autorefractor is surely the best innovations in recent times. The best thing about the equipment is it can be carried anywhere and the patients who have been physically unfit can get this test done through this equipment at their place.

Wave analysis through Autorefractors

Through wave front the detection capability gets better. The different aberrations of human eye are easier to detent through this feature of wave front. Optometrist find this device very useful in deciding about the contact lenses or the glasses that might be required. There are consistently new developments that come up like wave front.


Now many optometrists have started using HRK-7000 as this one helps in making the readings accurate. Companies like Huvitz are performing different analysis in through wave front technique and make some special autorefractor.
