Robot performs delicate eye surgery on six patients

May 10, 2017

London, May 10: A robot has been used to successfully perform a delicate eye surgery on six patients in a world- first trial which shows that robotic procedures can be more accurate than the trained human hand.

EyeSurgeryIn the trial, researchers from the University of Oxford in the UK performed the membrane-removal surgery on 12 patients. Six of those patients underwent the traditional procedure, and six underwent the new robotic technique.

Researchers found that those patients in the robot group experienced significantly fewer hemorrhages and less damage to the retina. The robot acts like a mechanical hand with seven independent motors that can make movements as precise as one micron, researchers said.

It operates inside the eye through a single hole less than one millimetre in diameter and goes in and out of the eye through this same hole during various steps of the procedure. However, the surgeon is in control, using a joystick and touch screen to manoeuvre the robot hand while monitoring movements through the operating microscope.

"The robotic technology is very exciting, and the ability to operate under the retina safely will represent a huge advance in developing genetic and stem cell treatments for retinal disease," Robert E MacLaren, professor at the University of Oxford was quoted as saying by 'Live Science'.

"We have demonstrated safety in a delicate operation. The system can provide high precision at 10 microns in all three primary directions, which is about 10 times more precise than what a surgeon can do," said Marc de Smet from University of Eindhoven in the Netherlands, who helped design the robot.

The team first used the system on a 70-year-old priest from UK, in September las year. Upon the success of that surgery, they conducted a study on 11 more patients in a randomised clinical trial, hoping to measure the robotic system's accuracy compared to the human hand.

New Delhi, Jul 13: The Telecom Regulatory Authority of India (TRAI) has blocked Bharti Airtel's Platinum and Vodafone Idea's RedX premium plans that offer faster data speeds and priority services to customers as both the plans were violating net neutrality norms.

The telecom watchdog has asked Bharti Airtel to explain within seven days how such a similar plan being launched does not violate the rules of net neutrality.

Vodafone Idea's RedX plan has been in the market since November 2019. They made some modifications in May 2020 and the Bharti Airtel was soon going to launch a similar plan.

According to TRAI, the higher speed for premium customers discriminate against others and violates net neutrality.

Responding to TRAI's move, Airtel spokesperson said: "We are passionate about delivering the best network and service experience to all our customers. This is why we have a relentless obsession to eliminate faults and have been consistently recognised by international agencies as the best network in terms of speed, latency and video experience."

"At the same time, we want to keep raising the bar for our post-paid customers in terms of service and responsiveness. This is an ongoing effort at our end," the spokesperson said.

Google on Monday announced it is gradually winding down its free public Wi-Fi Station programme currently available at over 400 railway stations in India, and will work with the Indian Railways and Railtel Corporation to help them with existing sites so they can remain useful resources for people.

Google launched its Station initiative in India in 2015 to bring fast, free public Wi-Fi to over 400 of the busiest railway stations in the country by mid-2020.

"We crossed that number by June 2018 and implemented Station in thousands of other locations around the country in partnership with telecommunications companies, ISPs and local authorities," Caesar Sengupta, Vice President, Payments and Next Billion Users, Google, said in a statement.

"Over time, partners in other countries asked for Station too and we responded accordingly. We're grateful for these partnerships, especially with the Indian Railways and the Government of India, that helped us serve millions of users over the last few years," he added.

According to Google, the decision to shut Station has been taken keeping the affordable mobile data plans and mobile connectivity in mind that is improving globally including in India.

"India, specifically now has among the cheapest mobile data per GB in the world, with mobile data prices having reduced by 95 per cent in the last 5 years, as per TRAI in 2019," said Sengupta.

The Indian users consume close to 10GB of data, each month, on average, according to reports.

"Our commitment to supporting the next billion users remains stronger than ever, from continuing our efforts to make the internet work for more people and building more relevant and helpful apps and services," Sengupta noted.

Global networking giant Cisco last year teamed up with Google to roll out free, high-speed public Wi-Fi access globally, starting with India.

The first pilot under the partnership was rolled out at 35 locations in Bengaluru.

Sengupta said that in addition to the changed context, the challenge of varying technical requirements and infrastructure among our partners across countries has also made it difficult for Station to scale and be sustainable, especially for our partners.

"And when we evaluate where we can truly make an impact in the future, we see greater need and bigger opportunities in building products and features tailored to work better for the next billion user markets," he said.

Washington D.C., Jan 12: A recent study has claimed that people end up wasting almost an entire day when they take a vacation.

This can happen while standing in a queue or searching for places to visit, people do not keep a count of the time they have actually utilised during the trip. As a result, they end up doing much lesser activities than they originally had planned.

According to a recent report in Fox News, the study has also shared the fact that people try to justify time waste with planning and scheduling activities whereas the truth is that these things can be done well ahead to save time during the trip.

The average time waste according to the study commissioned by Sykes Holiday Cottages also said the people taking a seven days' trip waste a minimum of 17-and-a-half hours to figure out various factors.

But there are other causes involved as well. When one visits any crowded location, the real-time spent to enjoy the location is lesser than the time spent on reaching and trying to get involved. For instance, if one visits an amusement park, the activities take lesser time than the preparatory and other phases.
