Abstract

PURPOSE: To evaluate the stability of three different hydrophilic acrylic intraocular lenses (IOLs), which have different shapes. IOLs included in this study are three-piece acrylic IOL with PMMA (Polymethylmethacrylate) haptics (Hydroview(R) H60M, Bausch &Lomb, U.S.A), one-piece acrylic IOL with broad optic-haptic junction (Centerflex(R) 570H, RAYNER, UK), and one-piece acrylic IOL with narrow optic-haptic junction (Aquasens, Ophthalmic Innovations International, U.S.A).
METHODS
We evaluated 69 patients (100 eyes) who had undergone cataract surgeries and who had hydrophilic acrylic IOLs implanted from September, 2003 to March, 2004. Forty eyes implanted with three-piece acrylic IOL with PMMA haptics, 40 eyes implanted with one-piece acrylic IOL with broad optic-haptic junction, and 20 eyes implanted with one-piece acrylic IOL with narrow optic-haptic junction were included. Slit lamp examination, best corrected visual acuity (BCVA), anterior chamber depth (ACD), refraction, and IOL decentration were evaluated at one week and at one, three, and six months postoperatively.
RESULTS
There was no statistically significant difference in BCVA, ACD, mean SE or decentration between patients implanted with three different types of hydrophilic acrylic IOL during the 6 month follow-up period (P>0.05). However, Postoperative myopic shift was discovered in 4 eyes (4/20) with Aquasens.
CONCLUSIONS
There were no statistically significant difference in the Stabilities of the 3-different hydrophilic acrylic IOLs. However, patients who were implanted Aquasens shold be observed carefully because Aquasense has the posibilitiy to have myopic shift more than 1 Dioptor.
