Precise and finite measurements are essential in many
surgeries, because surgeries are all about precision; sometimes even a
millimeter matters. Let`s think about eye surgery for instance.
Biometrics is the process of calculating the power of the
artificial lens to be implanted in the eye of the patient with cataract. If the
patient has a very advanced cataract, he/ she will probably be happy to see,
after the operation, even with glasses; however, if he/ she is a patient who
has higher demands and wants to have the best lens possible (even a multifocal
lens!), to ensure a better view without wearing glasses, then precise
biometrics is extremely important.
The concept of optical biometrics appeared precisely from
the necessity of making accurate measurements. The technology behind it
involves using lasers for measurements, which means that the contact with the
patient's eye is avoided.
Unfortunately, optical biometrics cannot be applied in all
cases; patients with very advanced cataracts cannot benefit from this method
and require ultrasonic biometry instead.
If we remain in the field of eye surgery, we must also add
that there are now computerized systems that allow high precision measurements
for surgical intervention and, at the same time, they guide the surgeon during
the operation to make precise incisions and find an accurate positioning for
the artificial lens. Visit Apiary Medical for precision surgery tools.
