Phacoemulsification of cataract

The most commonly applied method for surgical removal of cataract is phacoemulsification. In this operation, the blurred lens is broken down into pieces by ultrasound and then removed from the eye. The removed lens is replaced with intraocular lens implant (IOL) with suitably selected parameters.

The surgery procedure:

  • a patient is asked to wear his pyjamas in the pre-operation room, where an ophthalmologist prepares the eye for the surgery by applying several suitable drops and an anaesthesiologist carries out an examination;
  • a patient wears an apron and a protective cap and goes to the operating room;
  • a patient is laid on the operating table and connected to equipment monitoring cardiac event, blood pressure and saturation. Intravenous drips provide infusion liquids together with pain-killers and sedatives, while a nasal tube delivers oxygen. Throughout the entire operation a patient is under the anaesthesiologist care, is conscious and contacts with the operator. It is important that the patient directs his/her sight in accordance with the doctor’s instructions.
  • the skin around the eye is disinfected; anaesthetic drops are applied to the eye and the head is wrapped with sterile surgical cloth. The surgical microscope is set in appropriate position.
  • a small incision of approx. 3 mm is made in the eye through which the ophthalmologist inserts a phacoemulsifier head tip, which, by emitting ultrasounds of suitable frequency, breaks down the blurred lens into tiny pieces.
  • fragments of the broken lens are aspired (suctioned out) from the eye with the use of the phacoemulsifier tips.
  • in the course of the surgery special irrigation fluids replacing watery fluid of the front eyeball are introduced into the eye as well as a viscoelastic preparation protecting corneal endothelial cells during the surgery and facilitating the implantation of phakic lens.
  • in the place of the removed lens, the ophthalmologist inserts through the incision made in the eye a foldable phakic lens with suitably selected ophthalmologic parameters for a given patient.
  • after the surgery the patient leaves the operating room and stays in bed in the post-operative room. Following anaesthesiologist and ophthalmologist check-ups, the patient is discharged home. Next day the patient comes in for a check-up visit.



Strong points of the method:

  • a small incision of about 3 mm made in the eye through which the phacoemulsifier probe is inserted in the first stage and then a foldable lens is implanted;
  • no need to stitch the post-operative wound, which is self-sealing under the influence of intraocular pressure;
  • the possibility of a surgery performed with the application of aesthetic drops;
  • the length of surgery minimized to several minutes;
  • a patient does not have to stay in hospital and leaves the centre after a few hours;
  • short recuperation time of the operated eye;
  • lowered risk of post-operative complications;
