title: Opacification of the Hydroview H60M intraocular lens: total patient recall.
abstract: OBJECTIVE
  To report the prevalence of intraocular lens (IOL) opacification and related clinical features in patients implanted with Hydroview IOL.
  
  
  METHODS
  Gloucestershire Eye Unit, Gloucestershire, United Kingdom.
  
  
  METHODS
  A total of 1330 eyes of 1265 patients who had cataract surgery with Hydroview IOL implantation between September 2000 and April 2001 were reviewed between April and October 2004. The visual acuity, visual symptoms, IOL status, and associated ocular comorbidity were recorded.
  
  
  RESULTS
  One hundred ninety-three (14.5%) of 1330 eyes had evidence of IOL opacification. A total of 56 (4.2%) had visually significant opacification and had IOL exchange. The prevalence of IOL opacification ranged from 1.1% in patients who had surgery in September 2000 to 36.3% in the December 2000 group. In eyes with IOL opacification, the visual symptoms were decreased vision (57%), glare (32%), and mistiness of vision (27%). One hundred forty-four eyes (75%) with IOL opacification had visual acuity of 6/12 or better; 21.5% of diabetic eyes had IOL opacification compared with 14.3% of nondiabetic eyes (P =.06); 20.5% of glaucomatous eyes had IOL opacification compared with 14.0% of nonglaucomatous eyes (P = .033).
  
  
  CONCLUSIONS
  This is the first large sample recall of patients implanted with the Hydroview H60M IOL. The overall prevalence of IOL opacification was 14.5%, with peak prevalence in patients who had surgery in December 2000.
