What is Lasik eye surgery?

What is Lasik eye surgery?

LASIK stands for Laser-Assisted In Situ Keratomileusis.

LASIK eye surgery is used to correct the vision as it reduces the need for eyeglasses and contact lenses to correct the most common vision problems (e.g., nearsightedness, farsightedness, astigmatism).

The procedure relies on the expertise of a surgeon who’s trained in the ophthalmic surgery.

Role of Biomedical Sales Engineer

Role of Biomedical Sales Engineer

No one dreams about working as a sales engineer after graduating as a biomedical engineer, but with limited options available one may try his hand at this job.

Biomedical being such a huge industry and its product base being enormous the companies are in need for sales and marketing people. Many national and multi-national companies have set their base and there are distributors for the products of these companies, so the job opportunities are always available.

Having said this it is always better to work for a Parent company than for a distributor.

A dream job would be getting an opportunity to work for Draeger, Maquet, GE, Philips, Smiths Medical, Olympus.

List of 25 Dream companies every biomedical engineer wants to work for

Indian doctor Harminder Dua finds new cornea layer

An Indian doctor in Britain has discovered a new layer in the human cornea that could help cure blindness due to glaucoma.


Harminder Dua from the University of Nottingham discovered that the layer -15 microns thick but incredibly tough— plays a vital role in the structure of the tissue that controls the flow of fluid from the eye.

The findings could shed new light on glaucoma, the devastating disease caused by defective drainage of fluid from the eye and the world’s second leading cause of blindness.

New laparoscopic pressure sensors can make 3-D maps of tumours

New laparoscopic pressure sensors can make 3-D maps of tumours

During open surgery, doctors rely on their sense of touch to identify the edges of hidden tumours and to locate hidden blood vessels and other anatomical structures: a procedure they call palpation.

But during minimally invasive surgeries the ability to examine tissue through touch, called palpation, is lost. Instead, surgeons must manipulate the tissue with long, narrow instruments and rely on visual images from tiny cameras. But engineers in the United States, the United Kingdom, and elsewhere have designed new tools to help restore a surgeon’s sense of touch.

laparoscopic pressure sensors

The devices, dubbed palpation probes, are designed to be used laparoscopically and can detect changes in the stiffness of tissue. Tumours are harder than normal tissue, so they can be detected with a combination of pressure sensors and spatial positioning measurements. The readings are used to create a three-dimensional stiffness map that shows surgeons the margins of tumours.

Google lens: option for diabetics

Google lens: option for diabetics 

Google has said it is testing a “smart contact lens” that can help measure glucose levels in tears.

It uses a “tiny” wireless chip and a “miniaturised” glucose sensor embedded between two layers of lens material.

Lens looks like a typical contact lens on his index finger Sandwiched in this lens are two twinkling glitter-specks loaded with tens of thousands of miniaturized transistors. It’s ringed with a hair-thin antenna. Together these remarkable miniature electronics can monitor glucose levels in tears of diabetics and then wirelessly transmit them to a handheld device.

People suffering from the condition need to monitor their glucose levels regularly as sudden spikes or drops are dangerous. At present, the majority of them do so by testing drops of blood.

Google said it was testing a prototype of the lens that could “generate a reading once per second”.

The idea that all of that monitoring could be going on passively, through a contact lens, is especially promising for the world’s 382 million diabetics who need insulin and keep a close watch on their blood sugar.

Google said it was working with the US Food and Drug Administration (FDA) to bring the product to mainstream use.

It added that it would look for partners “who are experts in bringing products like this to market”.

Before the smart contact lens becomes official, Google will also have to determine whether measuring tear fluid is actually relevant for blood sugar levels.

App, device clicks selfie to monitor cholesterol

 App, device clicks selfie to monitor cholesterol

Scientists at Cornell University  have developed a new device which enables your smartphone’s camera to read your cholesterol level instantly – by clicking a selfie.

The gadget eliminates the need for clumsy, complicated, home cholesterol-testing devices.

Cornell University engineers claim the Smartphone Cholesterol Application for Rapid Diagnostics, or “smartCARD,” could save lives – by reading out cholesterol level in about a minute.

SPECT/MR imaging system makes its debut as new Hybrid Modality

SPECT/MR imaging system makes its debut as new Hybrid Modality 

SPECT/MR debuted this week as a new preclinical hybrid molecular imaging system with promises of higher resolution and lower dose.

The single photon emission tomography (SPECT) and magnetic resonance system was introduced at the Society of Nuclear Medicine and Molecular Imaging’s 2013 annual meeting in Vancouver, British Columbia.

SPECT/MR is different from other hybrid modalities because it allows for imaging with biomarkers labeled with a wide range of radionuclides.

SPECT/MR has a variety of applications, including imaging for cancer, cardiovascular and neurological diseases, thyroid and other endocrine disorders, trauma, inflammation and infection.

Embedded electronics on contact lenses

Embedded electronics on soft contact lenses

Soft contact lenses could display information to the wearer and provide continuous medical monitoring.

Currently transparent electrodes are usually made from a material known as indium tin oxide (ITO). Although it works, it is brittle, cracks and loses functionality if flexed. It also degrades over time, and is somewhat expensive due to the limited quantities of indium metal.


UNIST (Ulsan National Institute of Science and Technology) scientists have combined graphene with silver nanowires to form a thin, transparent and stretchable electrode.

Graphene is well known as good a candidate for transparent electrode because of their unique electrical properties and high mechanical flexibility. However, scalable graphene synthesis methods for commercialisation produces lower quality graphene with individual segments called grains that increase the electrical resistance at boundaries between these grains.

Silver nanowires, on the other hand, have high resistance because they are randomly oriented like a jumble of toothpicks facing in different directions. In this random orientation, there are many contact between nanowires, resulting in high resistance due to large junction resistance of nanowires.

Due to these drawbacks, neither is good for conducting electricity, but a hybrid structure, combined from two materials overcomes their weaknesses. It presents a high electrical and optical performance with mechanical flexibility and stretchability for flexible electronics.

There’s almost no change in its resistance when bent and folded. The structure developed by the research team, may soon find use in a variety of other applications.

The research team demonstrated Inorganic light-emitting diode (ILDED) devices fitted on a soft eye contact lens using the transparent, stretchable interconnects of the hybrid electrodes as an application example.

“We believe the hybridisation between twodimensional and one-dimensional nanomaterials presents a promising strategy toward flexible, wearable electronics and implantable biosensor devices, and indicate the substantial promise of future electronics,” said Jang-Ung Park, professor at UNIST, who led the effort.

As an in study, the LED embedded contact lens was worn by a live rabbit eye for five hours and none of abnormal behaviour, such as bloodshot eye or the rubbing of eye areas had been observed.
