title: Efficacy and stability of AT TORBI 709 M toric IOL.
abstract: OBJECTIVE
  To describe the intraocular rotational stability and refractive results of the toric AT TORBI 709 M (former AT.Comfort 464 TLC) intraocular lens (IOL) (Carl Zeiss Meditec AG, Jena, Germany).
  
  
  METHODS
  Forty-eight eyes of 32 consecutive patients with cataract and greater than 1 diopter of corneal astigmatism were included. Implantation of the toric IOL was performed after phacoemulsification. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), residual refractive sphere, residual keratometric and refractive cylinders, and toric IOL axis were measured before and 1, 3, and 6 months after surgery.
  
  
  RESULTS
  Mean logMAR UDVA and CDVA improved significantly after surgery (P < .05). UDVA was 20/40 or better in 88.1% of eyes and 20/25 or better in 61.9%. CDVA was 20/40 or better in 100% of eyes and 20/25 or better in 90.2%. Mean refractive cylinder decreased significantly from -2.23 ± 1.72 before to -0.43 ± 0.53 after surgery (P < .05). Vector analysis of attempted versus achieved correction showed 100% of eyes within ± 1.00 D and 95.2% within ± 0.50 D for J and 100% of eyes were within ± 1.00 D and 95.2% within ± 0.50 D for J. Mean toric IOL axis rotation was 4.42 ± 4.31 degrees (range: 0 to 16 degrees) and 86% of the lenses rotated less than 10 degrees.
  
  
  CONCLUSIONS
  The AT TORBI 709 M IOL has proved to be a predictable and effective device with good rotational stability for the correction of preexisting astigmatism during cataract surgery.
