Clinical Results in 1000 Cases of Acrysof Intraocular Lens Implantations

To evaluate the clinical results of implantation of Acrysof foldable intraocular lens[IOL], we retrospectively analyzed 814 patients who had been implanted with Acrysof IOLs in their eyes and followed-up over 6months postoperatively. Postoperative conditions such as best corrected visual acuity[BCVA], postoperative complications and capsular fibrosis were evaluated. Postoperative BCVA, with measurement above 0.7 was 83%and above 0.5 was 92%.If there was no ocular pathology, BCVA with measurement above 0.7 was 96.5%.Postoperative complications included 9.8%[80 cases]of posterior capsular opacity, 3.2%[28 cases]of microvacuole, and also anterior capsule contracture, haptic damage.7 cases of posterior capsular opacity[totally 80 cases]required Nd;Yag laser posterior capsulotomy.Capsular fibrosis[61.8%]was divided to 4 grades.Most of them were grade I or IIand above grade was 9.8%. In conclusion, the Acrysof IOL implantation showed good visual outcome and few postoperative complications, especially in PCO, it had excellent results.So, it will show excellent longterm visual prognosis including visual quality.

Four Cases of Multiple Vacuoles inside of Acrysof Intraocular Lens

Acrysof intraocular lens (IOL) (Alcon,Dallas,USA), the first commercially available foldable acrylic IOL, which was approved for marketing in the United states on December, 1994 and in the Korea on August, 1997.It is made with an acrylic/methacrylic polymer. Characteristics of the Acrysofistiguished from commonly used foldable silicon IOLs include improved elastic properties (not slippery when wet), slow and controlled unfolding, and a high refractory index resulting in a thinner lens. We experienced vacuolesin Acrysof IOLs which has no visual influence in 4 cases and report this unusual cases with a review of available literature.

A Clinical Cmparison Silicone and Acrysof IOLs

To evaluate and compare the clinical results of implantation of the Silicone and Acrysof IOLs in early postoperative period(to 3 months), we retrospectively analyzed 30 patients who had taken clear cornea incision and been implanted with Silicone IOL in one eye and Acrysof IOL in the other eye. There were no statistically significant difference in postoperative corrected visual acuity, corneal edema and postoperative astigmatic changes between silicone and acrysof IOLs. But, the rates of postoperative capsular fibrosis and contracture of Silicone IOL was higher than those of Acrysof IOL. In conclusion, in the degree and rate of after-cataract, Acrysof IOLs are more useful than silicone IOLs; therefore, more excellent in longterm visual prognosis. Further studies will be needed for the evaluation of clinical safety and efficacy.
