Do you get sick of having to take your glasses on and off just to read the newspaper, a menu, or when you need to fill out a form? Well a change is in the air, and it’s all bad news for spectacles.
Implantable corneal inlays are clear, donut-shaped rings that can be easily and quickly inserted into a small pocket in the cornea covering the front of the eye. The inlay acts like a camera aperture, adjusting the depth of field so that the wearer can see both near and far. This means long distance vision is not compromised and prevents the need for the constant putting on and taking off of glasses.
Findings from a clinical study using the KAMRA device were presented at the latest American Academy of Ophthalmology annual meeting. 503 patients with vision problems took part in the study, and of these, 420 patients achieved 20/40 vision – the standard for being able to drive a vehicle or read a newspaper without glasses.
The KAMRA inlay joins a host of other inlays awaiting approval before being marketed mainstream. Side effects are few. Original prototypes caused some haziness; however, improvements in inlay design have made the effect less common. The inlays are also removable, unlike other procedures such as LASIK.
