Cataract surgery delay – does it contribute to dementia risk?

11th December 2021, Dr Chee L Khoo

Cataracts

Cataract is a leading cause of blindness worldwide, affecting more than 35 million people globally and causing blindness in approximately 20 million. Visual impairment is an important dementia risk. Addressing sensory loss from visual impairment that affects older adults may be a potentially modifiable risk factor for dementia in late life (1,2) Because sensory impairments and dementia are both strongly associated with aging the link between sensory impairment and dementia may have important implications for individual and global public health, particularly if interventions to improve sensory function reduce dementia risk (3).…

Floppy Iris Syndrome – is your patient at risk?

12th November 2018, Dr Chee L Khoo

Intraoperative floppy iris syndrome (IFIS) was first described by Chang and Campbell. It is characterised by floppiness of the iris, miosis and ultimately, iris prolapse through the surgical wounds. It can occur during surgery for cataract and if not anticipated, it increases the risk of posterior capsule rupture, vitreous loss, retained nuclear fragments, post op intraocular pressure spikes, irido-dialysis, hyphema and corneal endothelial loss.…
