Inclusion criteria
* bilateral age-related cataract * good overall physical constitution * LOCS 2-5
Exclusion criteria
* previous intraocular surgery or ocular trauma * previous corneal pathology * previous endothelial cell count \<1200 * glaucoma * uveitis * PEX * diabetic retinopathy and any other severe retinal pathology that would make a postoperative visual acuity of 20/40 (decimal equivalent = 0.5) or better unlikely * intraocular complication like posterior capsular * postoperative comlpications (e.g. postoperative uveitis)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| phacoemulsification time | 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 |
| effective phacoemulsification time | intraoperativ | 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) |
| fluid volume | intraoperativ | amount of BSS used for dividing and conquering |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| postoperative corneal oedema | 1 day, 1 week, 6 months | central corneal thickness |
| postoperative endotheial cell loss | 6 months | — |
