Summary

Phacoemulsification (phaco) and extracapsular extraction (ECCE) show similar outcomes, but phaco offers advantages like smaller incisions. Postoperative astigmatism is significantly lower with phacoemulsification.

Area of Science:

  • Ophthalmology
  • Surgical Techniques

Background:

  • Phacoemulsification (phaco) is preferred by 76% of surgeons in German-speaking countries for cataract extraction.
  • Extracapsular extraction (ECCE) is used by the remaining 24%, often with different anterior capsule opening techniques.

Purpose of the Study:

  • To prospectively compare phacoemulsification and extracapsular extraction outcomes.
  • To evaluate differences in irrigation volume, duration, endothelial cell loss, and postoperative astigmatism.

Main Methods:

  • A prospective study comparing 100 consecutive patients undergoing phacoemulsification versus 100 undergoing ECCE.
  • Measurements included irrigation volume and duration, endothelial cell loss, and postoperative astigmatism.

Main Results:

Related Experiment Videos

  • Mean irrigation volume was higher in the phaco group (96.6 ml) than ECCE (48.1 ml).
  • Endothelial cell loss was similar (7.9% vs. 7.1%), with no correlation to irrigation duration.
  • Mean postoperative astigmatism was significantly lower after phacoemulsification (1.0 dpt) compared to ECCE (3.3 dpt).

Conclusions:

  • Phacoemulsification and ECCE yield comparable outcomes, except for lower postoperative astigmatism with phaco.
  • Phacoemulsification offers advantages including smaller incisions, closed systems, and controlled intraocular pressure.
