Drug research could prevent secondary cataract

Scientists may have found a way to prevent complications from surgery to treat cataract — the world’s leading cause of blindness. It’s estimated that by the year 2020, 32 million people will need cataract surgery — which works well to restore vision, but can lead to ‘secondary cataract’ forming. The research team reveal how a new focus for drugs to treat age-related macular degeneration could reduce the need for millions of follow-up eye operations.
