title: Intraoperative performance and longterm outcome of phacoemulsification in age-related cataract.
abstract: OBJECTIVE
  To evaluate intraoperative performance and longterm surgical outcome after phacoemulsification of age-related cataracts.
  
  
  METHODS
  Prospective, observational, non-comparative study of 165 consecutive eyes undergoing phacoemulsification with nuclear sclerosis Grade I to III (Scale I to V). Preoperative evaluation included specular microscopy. Phacoemulsification was performed by a single surgeon using a standardised surgical technique under topical anaesthesia. Intraoperatively, effective phaco time (EPT), wound site thermal injury (WSTI), serious complications (eg. vitreous loss, posterior capsule rupture, zonulolysis) and intraoperative posterior capsule opacification (plaque) were evaluated. Postoperatively, posterior capsule opacification (PCO), Neodymium:YAG (Nd:YAG) laser posterior capsulotomy rate, corneal endothelial count, best corrected visual acuity and cystoid macular oedema were evaluated. Eyes were examined at 6 months and then yearly for 3 years.
  
  
  RESULTS
  Mean ages of 78 males and 87 females were 59.12 +/- 8.56 and 58.34 +/- 7.45 years respectively. EPT was 36 +/- 19 seconds and WSTI occurred in 7 eyes (4.7%). No serious intraocular complications occurred. Intraoperative posterior capsule opacification (plaque) was present in 21 eyes (13.93%). Postoperatively, PCO occurred in 8 eyes (4.84%) and Nd:YAG laser posterior capsulotomy was performed in 3 eyes (1.8%). Endothelial cell loss was 7.1% at 3 years follow-up. At the end of 3 years follow-up, 146 eyes (88.89%) maintained a best corrected visual acuity of > or = 6/12. Cystoid macular oedema did not occur in any eye at 1 and 6 months' follow-up.
  
  
  CONCLUSIONS
  PCO rates and endothelial cell loss were acceptable. Consistent and reproducible outcome can be obtained after phacoemulsification of age related cataracts (grade I to III).
