title: [Residue of sodium hyaluronate in aqueous humor following intraocular lens implantation].
abstract: OBJECTIVE
  To determine the residue of sodium hyaluronate in aqueous humor following intraocular lens (IOL) implantation.
  
  
  METHODS
  The percentage concentration of sodium hyaluronate in aqueous humor in 23 patients (25 eyes) having undergone IOL implantation was measured by Shimadzu UV-3101 ultraviolet spectrophotometer before and after irrigation with BSS 2 ml, 5 ml and 8 ml.
  
  
  RESULTS
  The different percentage concentrations of sodium hyaluronate were 65.50% +/- 18.12%, 10.20% +/- 4.80%, 2.19% +/- 1.83% and 0.70% +/- 0.91%.
  
  
  CONCLUSIONS
  Replacement of aqueous humor by BSS 2 ml can eliminate the most part of sodium hyaluronate. Replacement of aqueous humor by BSS 8 ml can decrease the residue of sodium hyaluronate to trace amount and the postoperative intraocular pressure can maintain in normal range.
