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 19: Indian equities will be driven by a host of factors like corporate earnings, coronavirus cases trend and geo-political developments this week, according to analysts.

Market participants will also keenly watch the progress of monsoon, with experts saying that the farm sector revival will play a key role in lifting the coronavirus-hit economy.

"With no major event, the ongoing earnings season and global cues will continue to dictate the market trend. Besides, the progress of monsoon will also be closely watched," Ajit Mishra, VP - Research, Religare Broking, said.

Globally, the rising coronavirus infections and geo-political tensions have created uncertainty on the economic recovery front.

With India's COVID-19 cases fast approaching the 11 lakh mark, the third-highest behind the US and Brazil, and the death toll nearing 27,000, participants are expected to tread cautiously going forward.

At global level, confirmed COVID-19 cases have crossed 1.4 crore and deaths totalled about 6 lakh.

Markets globally will closely follow developments on the trade and political level between the US and China, according to analysts.

"We would continue witnessing stock-specific action as the earnings season unfold. Though the near-term momentum looks positive, we would advise traders to be cautious, given flaring US-China trade relations, persistent rise in virus cases and implementation of fresh lockdowns in parts of the country," said Siddhartha Khemka, Head - Retail Research, Motilal Oswal Financial Services Ltd.

HDFC Bank will remain in focus on Monday after having announced its June quarter earnings on Saturday.

The lender reported 19.6 per cent rise in its standalone net profit at Rs 6,658.62 crore for April-June 2020; while its income rose to Rs 34,453.28 crore during the quarter.

Other major companies to announce their quarterly results this week are Axis Bank, Bajaj Finance, Hindustan Unilever Limited, Bajaj Auto and ITC.

"Going ahead market participants will closely track the development related to covid vaccine, the rising infection of coronavirus, development on economic activities, corporate earnings and US-China relationship," said Sumeet Bagadia, Executive Director, Choice Broking.

On weekly basis, the Sensex gathered 425.81 points or 1.16 per cent, and the Nifty gained 133.65 points or 1.24 per cent.

Consumer watchdog Which? has claimed that more than one billion Android phones and tablets are vulnerable to hackers as they no longer supported by security updates.

According to the research report, the most at-risk phones are any that run Android 4 or older and those smartphones running Android 7.0 which can not be updated are also at risk.

Based on data from Google analysed by Which?, two in five android device users around the world are no longer receiving the important updates. Currently, those devices are unlikely to have issues, but the lack of security leaves them open to attack.

"It is very concerning that expensive Android devices have such a short shelf life before they lose security support, leaving millions of users at risk of serious consequences if they fall victim to hackers," Kate Bevan editor Which? said in a statement.

"Google and phone manufacturers need to be upfront about security updates with clear information about how long they will last and what customers should do when they run out. The government must also push ahead with planned legislation to ensure manufacturers are far more transparent about security updates for smart devices and their impact on consumers," Kate added.

Android phone released around 2012 or earlier, including popular models like the Samsung Galaxy S3 and Sony Xperia S, are particularly at risk to hackers.

Which? has made suggestions to Android users on what to consider if they have an older phone that may be at risk.

Any Android device which is more than two years old, check whether it can be updated to a newer version of the operating system. If it is on an earlier version than Android 7.0 Nougat, try to update via Settings> System>Advanced System update.

In case a user is not able tto update the phone, the device could be at risk of being hacked if it is running a version of Android 4 or lower.

A user also need to be careful about downloading apps outside the Google Play store and should also install a mobile anti-virus via an app.

New Delhi, Mar 14: Excise duty on petrol and diesel was on Saturday hiked by ₹3 per litre as the government looked to mop up gains arising from fall in international oil prices.

Special excise duty on petrol was hiked by ₹2 to ₹8 per litre incase of petrol and to Rs 4 incase of diesel, an official notification said.

Additionally, road cess on petrol was raised by ₹1 per litre each on petrol and diesel to ₹10.

The increase in excise duty would in normal course result in a hike in petrol and diesel prices but most of it would be adjusted against the fall in rates that would have necessitated because of slump in international oil prices.
