ABSTRACT
PURPOSE:
To evaluate and compare the postoperative rotational stability of a 1-piece acrylic toric intraocular lens (IOL) (Acrysof) and a plate-haptic silicone toric IOL (Staar) in Asian eyes.SETTING:
Singapore National Eye Centre, Singapore.DESIGN:
Prospective randomized control trial.METHODS:
Eyes of Chinese patients having cataract surgery were randomized to receive the acrylic toric IOL or the silicone toric IOL. Postoperatively, patients returned at 1 day, 1 week, and 1 and 3 months. The eyes were dilated and slitlamp retroillumination photography of the toric IOL was performed to assess rotational stability.RESULTS:
The acrylic IOL was implanted in 24 eyes and the silicone IOL in 26 eyes. The mean age of the patients was 68.2 years (range 42 to 82 years). The mean IOL rotation from baseline to 3 months postoperatively was 4.23 ± 4.28 degrees in the acrylic IOL group and 9.42 ± 7.80 degrees in the silicone IOL group; the difference was statistically significant (P=.01). Of the acrylic IOLs, 73% were rotated less than 5 degrees at 3 months; none was rotated more than 15 degrees at 3 months. The silicone toric IOLs showed greater rotational movement, with 37% being rotated less than 5 degrees and 21% being rotated more than 15 degrees.CONCLUSION:
The acrylic toric IOL had better rotational stability than the silicone toric IOL.
