Eye surgeons were dreaming since decades about
finding a way to treat cataract ( abnormal eye lens densities leading to
decreased lens transparency ) with the least trauma and surgical incision , that
would allow the patient to move and do the usual daily work , quickly after the
operation .
This dream came true with the invention of the Phaco instrument which is used
nowadays to perform more than
85 % of cataract operations .
|
Phaco:
This instrument emits ultrasound waves with a frequency of 40000 / sec
which leads to the break down of cataract and then it is resorbed and
the operation ends without |
|
To sum up , this technique
achieved the following :
1 – Swift cataract cure with very short convalescence period .
2 - The technique could be used to treat early stage cataract .
3 - The operation is done under local anesthesia and with a surgical incision of
3 to 3.2 mm in comparison with the previous classical surgical operations which
needed an incision of about 6 to 8 mm , which means much less eye trauma .
