  • previous intraocular surgery or ocular trauma
  • previous corneal pathology
  • previous endothelial cell count <1200

Treatment and study plan

cataract surgery

Procedure

Primary outcomes

  1. phacoemulsification time

    Time frame: intraoperative

    time spent for the phacoemulsification process was the phacoemulsification tip time (PTT) needed to divide the nucleus and the PTT needed to conquer it

  2. effective phacoemulsification time

    Time frame: intraoperative

    time in seconds required had 100% power been used throughout the phacoemulsification process documented for the separation of the nucleus (divide) and the aspiration of the quadrants (conquer)

  3. fluid volume

    Time frame: intraoperative

    amount of BSS used for dividing and conquering

Secondary outcomes

  1. postoperative corneal oedema

    Time frame: 1 day, 1 week, 6 months

    central corneal thickness

  2. postoperative endotheial cell loss

    Time frame: 6 months
