The device is a corneal inlay (corneal implant) used to improve near vision.


The USA’s Food and Drug Administration (FDA) issued a safety communication informing users that implantation of this device has led to an increased occurrence of corneal haze.

The cited study shows that 75% of 150 enrolled patients developed corneal haze. In 42% of patients, the corneal haze has been present in the central region of the cornea.

There is no specific guidance regarding frequency of follow-up from the manufacturer; the clinician should assess the risk of corneal haze in individual patients.

It is unknown how many Raindrop Near Vision Inlay devices may be placed on the market in the UK.
