NEW YORK (Reuters Health) - A new surgical device called a pulsed electron avalanche knife (PEAK-fc), which cuts tissue with short bursts of electric pulses, makes it easier to perform cataract surgery in complicated cases, according to a report in the British Journal of Ophthalmology.Cataracts develop as the lens of the eye becomes clouded. The risk of this common eye problem increases with age and with exposure to other risk factors such as UV light exposure, smoking, and diabetes. Blurred vision, blare, and cloudy spots are common symptoms. If indicated, cataracts can be treated by replacing the natural lens with an artificial one.
