title: Astigmatism management in cataract surgery with the AcrySof toric intraocular lens.
abstract: OBJECTIVE
  To present clinical data from a single-center prospective clinical trial of the AcrySof toric intraocular lens (IOL).
  
  
  METHODS
  Academic Hospital Maastricht, Maastricht, The Netherlands.
  
  
  METHODS
  Fifty-three eyes (43 patients) had implantation of an AcrySof toric IOL. Three toric models were evaluated in cylinder powers of 1.50 diopters (D) (SN60T3; T3 group, n = 16), 2.25 D (SN60T4; T4 group, n = 14), and 3.00 D (SN60T5; T5 group, n = 23) at the IOL plane. The T5 group was subdivided into eyes that could be fully corrected (T5a, n = 13) and eyes that could be partially corrected (T5b, n = 10).
  
  
  RESULTS
  Four months postoperatively, the mean uncorrected visual acuity (UCVA) was 0.77 +/- 0.23 in the T3 group, 0.93 +/- 0.23 in the T4 group, 0.82 +/- 0.15 in the T5a group, and 0.47 +/- 0.13 in the T5b group. More than 90% of the combined eyes in the T3, T4, and T5a groups achieved a UCVA of 20/40 or better, and almost 80% achieved a UCVA of 20/25 or better. Residual refractive astigmatism of less than 0.75 D was achieved in 74% of eyes and of less than 1.00 D in 91%. The mean IOL misalignment was 2.5 +/- 2.1 degrees in the T3 group, 3.5 +/- 2.3 degrees in the T4 group, and 4.1 +/- 3.5 degrees in the T5 group.
  
  
  CONCLUSIONS
  Implantation of the AcrySof toric IOL proved to be an effective, safe, and predictable method of managing corneal astigmatism in cataract patients.
