Doctors at Narayana Nethralaya, Bengaluru, have collaborated with researchers at the Indian Institute of Science (IISc.) High-speed imaging and aerodynamic models were used to visualise the generation of droplets during procedures such as cataract and LASIK surgeries. The first study focused on phacoemulsification, a type of cataract surgery where an ultrasonic needle is used to break up the cataract. The fluids are then suctioned out and the eye is rehydrated with a balanced salt solution. The researchers have suggested replacing the salt solution with more gelatinous or viscous materials to prevent fluid spurting and aerosol generation.
