A few days ago one of my visitor ask me whether "Do you know about the contact lens which monitors the eyeball pressure for better diagnosis of glaucoma?" . I tried to find him (or her?) a related article according that question.
In the article that i found later, it stated that the purpose of the article is to present a novel and minimally invasive approach to intraocular pressure (IOP) monitoring based on a sensing contact lens. It used material such Sensing Contact Lens Tonometer to detect spherical deformations of the eyeball (changes in cornea curvature) due to variations in IOP.
A soft contact lens with an embedded microfabricated strain gauge allowing the measurement of changes in corneal curvature is the key element of this method. The measurements of the contact lens were then compared to the ones from the pressure sensor, while pressure variations were induced through the cannula, according to the article.
Also provided with figure and ilustration to have a clear understanding. See more complete about Contact Lens Which Monitors Eyeball Pressure for Diagnosis of Glaucoma in pdf filetype available (source: iovs.org)
