Clinical results of three types of intraocular lenses for small incision surgery

We implanted three types of intraocular lens (IOL) in 30 eyes each by small-incision surgery. They were: foldable acryl IOL, foldable silicone IOL and polymethylmethacrylate (PMMA) IOL. We evaluated the following items during three years after surgery: visual acuity, astigmatism, glare disability, contrast sensitivity, tilt and decentering of IOL, corneal endothelial population, aqueous flare and aftercataract. Eyes foldable IOLs were more excellent than PMMA IOLs regarding visual acuity, astigmatism and aqueous flare which are indices for the early postoperative period. PMMA and acryl IOLs were more excellent than silicone IOLs regarding decentration of IOL and aftercataract which are indices for the late postoperative period.
