Definitions

  • This invention relates to a devise for useful to perform cataract operation 5 (eye operation)
  • the Femtosecond laser cataract machine is conceptualized to eliminate the complications of the procedures involved in perfuming cataract surgery
  • the nucleus of the cataract can be cracked to a desired size with a press of a button
  • the Femtosecond laser cataract machine will be within the reach of all ophthalmologists and easy to maintain.
  • Intraocular implant is aocular implant.
  • Femtosecond laser has the ability to ablate corneal tissue as shown by its use in corneal refractory surgery
  • anterior capsulorhexis can be performed This can be achieved by applying a focused circular beam of
  • the nucleus By applying a focused multiple radial beams of Femtosecond laser on the nucleus, the nucleus can be divided into pieces small enough to be aspirated by 28G cannula.
  • the devise to deliver the Femtosecond laser can be incorporated into A slit lamp or an operating microscope.
  • the components of the instruments will include:
  • the Femtosecond laser generator will be housed in a separate box It will have the gadgets to control the energy of the Femtosecond laser.
  • a console devise incorporated in the slit lamp/microscope to shape and focus the beam of the Femtosecond laser.
