Phaco is performed by inserting an ultrasound probe into
the eye to soften and emulsify the hardened lens, so that
it can be removed by aspiration through a titanium needle.
Incisions have become smaller with the advent of fold able
IOL's (Intra ocular lenses) and may be as small as 2.8mm.
Smaller incision Techniques used in Phacoemulsification
offer better postoperative benefits, including quick wound
healing with less inflammation, as well as a lower
incidence of astigmatism. In this manner
Phacoemulsification allows the surgeon more control over
the Intra ocular environment and the patient less physical
trauma.
The Phacoemulsification machine market is affected by
two important trends: the emergence of laser Phaco
technologies and technology enhancements reducing the
risk of rupturing or tearing the lens capsule.
As a comparison of how popular this procedure has
become, in the early 1980's only 10% of all cataract
extractions was performed by Phacoemulsification. Now
Phaco removal of cataracts accounts for more than 80%
of all surgeries performed today.
