NCT01255995

Brief Summary

  • The purpose of this study is to determine the natural course of IOL in PXF,
  • To demonstrate use of a clinical grading system for PXF,
  • To strategize a way to prevent IOL dislocation, subluxation post operatively,
  • To demonstrate intraoperative and long-term post-operative complications associated with phaco and PXF
  • To suggest evidence-based ways to minimize these complications, by using capsular tension rings (CTR), specific IOL material or size
