Scientists at University of Utah have developed a pair of glasses which have the ability to auto-adjust the focus of the lenses in the glasses. This will be very useful to the people who don’t want to use bifocal or progressive glasses. The lenses in the glasses are flexible and can change shape – they … Read more

The cornea is a transparent structure at the front of the eye and is mainly responsible for focusing of incoming light rays on the retina for clear vision. The health of cornea is maintained by stem cells present at the junction of cornea and sclera (the white part of the eye) called as limbus. If … Read more
In degenerative conditions like retinitis pigmentosa, the cells (mainly rods) which absorb light and convert the light energy into electrical energy gradually die. The resultant loss of vision is irreversible. For now, there is no treatment available for retinitis pigmentosa. Scientist all over the world are working on solutions to enhance vision and prevent blindness … Read more

Another stent for minimally invasive glaucoma surgery. It has been approved by FDA and will be in use in the USA in 2017. It has been found to be effective in refractory glaucoma. Patients have to use less anti-glaucoma medication after the surgery. The principle of any glaucoma surgery is to create a communication between … Read more
The last few decades have witnessed smaller incision cataract surgery. Now extending the same logic of early healing, lesser chances of complications and faster recovery to glaucoma surgeries, we are now witnessing increasing number of smaller incision glaucoma filtration surgery. Ex-Press Mini shunt is one such example. The Ex-Press Mini Glaucoma Shunt was originally developed … Read more
Cornea is an important part of the eye required for clear vision. Even microscopic changes in cornea can cause moderate to severe reduction in vision. These changes may be the result of various pathological processes, for instance infection, injury, metabolic disorders and degenerative changes. Depending on the cause, medical and surgical treatments including corneal transplantation … Read more
When people with significant visual compromise wish for a treatment or cure, they don’t expect more than some medical or traditional surgical procedures. The truth is we are fast approaching an age where bionic eyes not very different from what we saw in the science fiction movies ‘Terminator’ series are being developed with promising results. … Read more
