Plate-haptic silicone intraocular lens implantation: long-term results.
OBJECTIVE
To present the 10- to 12-year functional and morphological results of in-the-bag implantation of a foldable, plate-haptic, silicone posterior chamber intraocular lens (IOL).


METHODS
Department of Ophthalmology, University of Vienna Medical School, Vienna, Austria.


METHODS
Between September 1987 and December 1989, 160 silicone posterior chamber IOLs (Staar AA-4203C) were implanted in the capsular bag through a 3.5 mm corneoscleral incision after a continuous curvilinear capsulorhexis was created. In spring 1999, 36 patients (38 eyes) could be included in a follow-up examination.


RESULTS
The median follow-up was 10.5 years +/- 2 (SD). The mean visual acuity was 0.82 +/- 0.34. The mean refraction (spherical equivalent) was +0.57 diopter (D), an insignificant change from the mean at the first postoperative follow-up at 1 month (+0.40 D). Slitlamp examination showed mildly dispersed pigment on the IOL surface in 81.58% of cases. All IOLs had a Tyndall effect (clouding). In 84.21%, the effect was minimal, in 10.53% it was moderate, and in 5.26% it was more intense. Ninety-two percent of the IOLs were centered within 0.5 mm. Of the 22 cases of decentration (57.89%), 86.36% were toward the 12 o'clock position in the bag. The neodymium:YAG capsulotomy rate was 10.52%. There were no cases of IOL-related inflammation or a clinically significant cystoid macular edema.


CONCLUSIONS
The 10- to 12-year results suggest favorable clinical results of implantation of Staar AA-4203C plate-haptic, silicone posterior chamber IOLs.
