RESUMO
Modern methods of astigmatism correction in lens surgery are reviewed in the article. Keratorefractive, including laser-assisted, and intraocular techniques employing different models of toric intraocular lenses (IOL) are described. Current state of the problem is analyzed. Implantation of toric IOLs enables precise correction of corneal astigmatism simultaneously with cataract phacoemulsification.

Clinical study is performed to estimate the efficacy of Oftaquix in cataract phacoemulsification with intraocular lens (IOL) implantation. Obtained results show that Oftaquix prescription two days before surgery allows to eliminate bacterial agents from conjunctival cavity on the day of surgery. Significant and stable antibacterial effect is demonstrated. Bacteriological study on the 19-21 day after surgery revealed bacterial growth in 6.7% of patients in experimental group and in 30% of patients in control group.

Intraocular and spectacular chromatographic correction was comparatively studied by examining blindness and spatial contrast sensitivities in 81 patients (116 eyes) after implantation of achromatic and chromatic hydrophobic acrylic intraocular lenses (IOL). Spectacular chromatic correction with yellow filters was additionally used in patients with achromatic IOL. 1.5-2 years after surgery for developed posterior capsular opacities, higher ergonomic vales remained in patients with intraocular chromatic correction than in those who had achromatic IOL and had undergone additional spectacular chromatic correction.
