Comparison of visual results of implantation of silicone, acrylic, and hydrogel intraocular lenses

Abstract

Aim: To compare visual function after cataract surgery and implantation of three types of foldable lenses (silicone, acrylic, or hydrogel lenses).

Materials and Methods: Sixty one eyes undergoing small incision phacoemulsification surgery were randomly allocated to one of three types of intraocular lens. At 1 month postoperatively, visual function was measured and compared.

Results: At 1 month postoperatively, the mean best corrected visual acuity of eyes with silicone, acrylic, and hydrogel intraocular lenses (logarithmic Minimum Angle of Resolution scale) were 0.11, 0.12, and 0.14, respectively. The percentage of eyes with silicone, acrylic, and hydrogel intraocular lenses with a best corrected visual acuity of 20/25 or better were 72.22%, 66.67%, and 56.25%, respectively. The percent- age of these eyes with contrast sensitivity >= 1.50 was 72.22%, 71.43%, and 75.00% for silicone, acrylic, and hydrogel, respectively. There were no statistically significant differences in the mean best corrected visual acuity and contrast sensitivity between the three groups.

Conclusion: There were no significant differences in visual function in terms of best corrected visual acuity and contrast sensitivity between the three different types of intraocular lens.
