Comparison of the incidence of opacification of Hydroview hydrogel intraocular lenses with the ophthalmic viscosurgical device used during surgery

Abstract

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.

Localized opacification of hydrophilic acrylic intraocular lenses after procedures using intracameral injection of air or gas

“…3,4 Calcification of modern hydrophilic acrylic intraocular lenses (IOLs) appears to be a multifactorial problem, and factors related to IOL manufacture, IOL packaging, surgical techniques and adjuvants, as well as patient metabolic conditions may be implicated. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] We recently published a short correspondence calling attention to a phenomenon of calcification of various hydrophilic acrylic IOLs following procedures using intracameral injections of air or gas, including posterior lamellar keratoplasty techniques. 19 Since that publication, we have received new specimens of calcified hydrophilic acrylic IOLs of various designs explanted after DSEK or DSAEK.…”

“…The opacification was not associated with an anterior segment inflammatory reaction, and the Nd:YAG laser was ineffective in removing the calcified deposits from the IOLs. [5][6][7][8][9][10][11][12][13][14][15][16][17][18] There is increasing evidence of a distinctive pattern of calcification of various hydrophilic acrylic IOL designs following procedures using intracameral injections of air or gas. [19][20][21][22][24][25][26][27] Calcification was localized to the anterior surface/subsurface of the IOL and within the pupillary or capsulorhexis area.…”

Calcification of hydrophilic acrylic intraocular lenses in combined phacovitrectomy surgery

“…7-10 Systemic patientrelated factors include renal failure, 11,12 and ocular factors may include excessive postoperative inflammation. 13 Surgical factors may include the use of high phosphate-content OVDs such as chondroitin sulfate 4%-sodium hyaluronate 3% (Viscoat) 14 and tamponade agents such as silicone oil. 15 Case 1 had no preexisting systemic or ocular disease but had phacovitrectomy for retinal detachment repair.…”

Intraocular Lens Calcification After Keratoplasty

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14] In the majority of cases, certain IOL models were affected. The causes were claimed to be identified as specific manufacturing or packaging problems (primary calcification).…”
