Information about the actual corneal thickness is important because it can mask accurate readings of IOP and delay diagnosis of glaucoma. Unless taken into account, thicker corneas contribute to overestimation of IOP values and thinner corneas to underestimation. Thickness of the cornea among individuals can differ due to a variety of factors; an increasing cause is the popular laser refractive surgery. By combining the readings of the Non Contact Tonometer and built-in Pachymeter, the TX-20P will calculate automatically the corrected IOP and thus reduce the risk of misreading it; which could help to make a significant contribution to detecting potential glaucoma in patients.
The easy to use TX-20P combines a Tonometer and Pachymeter in one instrument, which allows for more accurate IOP measurements. Now you can measure IOP and central corneal thickness together and have the corrected IOP automatically recalculated for you with accuracy and speed. With its advanced, fully automatic examination with 3D alignment, the operation is extremely simple. Following a very basic alignment on the patient’s eye, with the press of a button the TX-20P will automatically align and focus and take multiple measurements of IOP and CCT on both eyes. Corrected IOP values will be calculated and printed out automatically.
The TX-20P removes the need for two separate devices and in addition eliminates time spent on manual calculations, thus enhancing practice efficiency and faster patient throughput. It is an incredibly compact and lightweight device that also allows for easy transportation, featuring a tilting 5.7 inch colour LCD screen which ensures the TX-20P can be operated while standing or sitting.
Mr. Yoshiyuki Masuko, Senior Director, Medical Systems Division, Canon Europe said: “Canon’s 70 year history in medical imaging has been built upon the basis of delivering the highest image quality to healthcare professionals to aid early detection of disease. With the TX-20P, Canon provides these professionals with its fastest, most efficient and accurate ophthalmic measurement device to date”.
At MIDO 2011, Canon’s ophthalmic products (including the TX-20P) can be found at the Frastema stand, number S11-T12, Pad 2.2. The event offers visitors an insight into the world of optics and ophthalmology.
