ABSTRACT
PURPOSE:
To determine the effect of intraoperative ophthalmic viscosurgical devices (OVDs) on late opacification of the Hydroview hydrogel intraocular lens (IOL) (Bausch & Lomb Surgical).SETTING:
Hamilton Health Sciences, McMaster University, Hamilton, Ontario, Canada.METHODS:
A retrospective study of 949 cases of Hydroview IOL implantations from February 1998 to September 2000 was conducted. Of the 949 implantations, 462 were performed by 1 surgeon (J.H.S.) using Viscoat (sodium chondroitin sulfate 4.0%-sodium hyaluronate 3.0%) and 487 were performed by a second surgeon (W.A.N.) using Biolon (sodium hyaluronate 1.0%). Surgical techniques were identical with the exception of surgeon OVD preference. The number of IOLs opacifying and requiring explantation was determined in each group.RESULTS:
Seventy-one Hydroview IOLs had surface calcification deposits that presented a mean of 39 months postoperatively. Twenty-two IOLs opacified sufficiently to warrant a recommendation of IOL explantation; 20 IOLs were explanted, and 2 surgeries were cancelled due to death or disability. In all cases of opacification, Viscoat had been used intraoperatively. This represented a 15.4% incidence of opacification in the Viscoat group, with 31.0% cases severe enough to warrant a recommendation of explantation.CONCLUSION:
The results suggest that the intraoperative use of Viscoat has a facilitating role in the development of late calcification and opacification of the Hydroview IOL.
