| Summary: |
Cataract is the leading
cause of reversible blindness in the world. The most
effective and common treatment is surgical removal of
the cloudy lens. There are two types of surgery that can
be used for cataract removal: intra-capsular (ICCE) and
extra-capsular (ECCE).The last one includes
phacoemulsification. Torsional ultrasound is a new
phacoemulsification technology that uses ultrasonic
oscillatory movement. Compared with the
forward-and-backward motion of the traditional
ultrasound tip, the side-to-side motion of the torsional
phaco tip provides reduced repulsion and improved
thermal safety, which is an extremely important factor
when working with hard cataracts. The lower flow and
reduced vacuum enhance protection of corneal endothelium.
In the last few years ultrasound phacoemulsification
enabled lens extraction through an incision of less than
2.0 mm (Small Incision Cataract Surgery). In micro
incision cataract surgery (MICS) an incision is less
than 1.5 mm. MICS provides advantages of wound stability,
improved control and reduced chamber turbulence,
resulting in very small induced astigmatism, early
visual rehabilitation and improved results. With the
advance of foldable IOLs, lenses can be implanted
through the same small incision that is created in the
phaco procedure. These IOLs are made of a flexible
material allowing them to be folded for implantation
using injector. Nowadays bimanual phacoemulsification
connected with MICS and IOL implantation is currently
the method of choice in cataract surgery. |
