With a rate of 33%, cataracts are the second leading cause of visual impairment after refractive errors in the world. In the UK alone, it is estimated that 30% of people older than 65 have a visually-impairing cataract in one or both eyes. Cataracts affect 24 million Americans aged 40 and older. However, more than 95% of cataract surgeries are successful.
It's no secret that digital technologies, especially smartphones, have become a prevalent aspect of our daily lives. This is true for all age groups, including children. As the numbers of people using smartphones steadily rise, eye care professionals are increasingly concerned about the effects of such high exposure to digital screens on eyesight.
Presbyopia is defined as the gradual loss of ability to see objects from up close. While such vision changes mostly affect individuals over the age of 40, an increasing prevalence of detrimental refractory vision changes has more recently been noted amongst younger individuals.
Over the next few years, the global eye care market will be shaped by a number of factors that include the world’s ageing population, reimbursement policies, technological advancements, regulatory requirements, and the growing public demand for better visual outcomes following cataract and refractive IOL surgery.
Presybopia, which means “old eye” in Greek, is a normal part of ageing and causes the eyes to gradually lose the ability to see things clearly from up close. The prevalence of presbyopia has been well studied in both high-income countries and developing countries, and it has been shown to mainly affect people above the age of 50.
