In India, nearly two lakh people need corneal transplant annually but only about 25% are able to to get it due to the lack of donors.
A new, artificial cornea made of bio-engineered collagen, which has been used successfully by the All India Institute of Medical Sciences(AIIMS) in 10 patients over the last two years, promises to fill this gap between demand and supply.
Vital statistics.
* What's a cornea? It's the transparent tissue that covers the eye. It lets in light and performs 2/3rds
of the focusing tasks.
* What's an artificial cornea?
- For decades, experiments have been made to see if an artificial cornea could replicate a real one.
- Synthetic prosthesis made from transparent thermoplastic is the most common.
- But due to complications involved in its implantation and side effects, scientists in Sweden and
Canada started experimenting with a bio-engineered alternative.
- They implanted synthetic collagen - a protein found in skin and other connective tissues - to
facilitate endogenous tissue generation and reported success in 2010.
- AIIMS' eye centre tried to replicate the experiment two years ago and implanted the same in 10
patients with success.
- Eye specialists said none of the patients who underwent artificial cornea implantation involving
synthetic collagen have suffered from rejection and there is significant improvement in their eye
sight.
- Only patients with vision loss due to thin or irregular cornea have been advised this treatment so
far.
* Dr. JS Titiyal, Professor and Head of Cornea, Cataract and Refractory Surgery Services along with
Dr. Namrata Sharma, Professor of Ophthalmology both of AIIMS, head the conduct of the
experiments.

Hoax Messages in Madhya Pradesh.
Fake What'sApp messages have whipped up rumours about "Armed Rohingyas on the prowl". This
comes close on the heels of several mob attacks and lynchings in the state. The fake What'sApp message that's viral in Bhopal and Indore, states, "Don't open the door at night if you hear babies crying. Groups of 15 to 20 armed Rohingyas are roaming the city with women and babies...when you hear a baby crying, please don't open the door. Please pass this message to all groups".
The message comes with a video footage of a woman police officer warning people against the 'crying baby ruse'. It's signed 'Bhopal CSP', making it seem like it's a genuine police alert.
The police are on the prowl to catch the miscreants.
Tailpiece.
It was cute of my course mate, Rajiva Prabhakar Padhye, to call up to catch up with me on various aspects and we had a long chat. He stays at Nagpur close to KC Murthy, my squadron mate and friend who had given me his contact number. He and I were in class 49 B at the NDA and together, we'd played many pranks during the Academics' classes.
