Summary

A significant portion of patients develop posterior capsule opacification (PCO) after cataract surgery. A "hidden" group with clinically significant PCO exists, impacting long-term visual outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Outcomes
  • Vision Science

Background:

  • Posterior capsule opacification (PCO) is a common complication after cataract surgery.
  • Long-term incidence and the presence of an untreated PCO group require further investigation.

Purpose of the Study:

  • To determine the incidence of PCO five years post-cataract surgery.
  • To identify a potential
  • hidden
  • group of patients with untreated PCO.

Main Methods:

  • A random sample of 164 patients undergoing extracapsular cataract extraction (ECCE) with intraocular lens implantation were studied.
  • Patients requiring neodymium:YAG (Nd:YAG) laser capsulotomy within five years were recorded.
  • Untreated patients were examined at five years to assess for PCO.

Main Results:

  • The overall estimated incidence of PCO five years after ECCE was 43%.
  • Of the untreated patients, 14% had clinically significant PCO.
  • Approximately 9% of the surgically treated population represented an untreated group with significant PCO.

Conclusions:

  • The incidence of PCO five years after ECCE is substantial.
  • A notable percentage of patients develop significant PCO that goes untreated.
  • This
  • hidden
  • PCO group should be considered in future research and clinical practice.
