PURPOSE: To retrospectively compare the early rotational stability of AcrySof toric IOL with that of Technis Toric.
METHODS:100 eyes of AcrySof toric IOL were compared with 100 eyes of Technis toric.In addition to the deviation from the desired axis,the change in refractive cylinder was measured 1 month postoperatively.
RESULTS: The two groups had similar distribution of patient profiles. In the AcrySof group 100% of the IOls were aligned within 15 degrees of the desired axis and in the Technis group 97%.The mean IOL rotation was 3.33+/-3.41 degrees in the AcrySof and 5.56+/-8.43 in Technis.One AcrySof IOL (1%) and Five technis(5%) were 15 degrees or more off axis.No AcrySof IOL and Three tecnis Toric IOls (3%)required surgical repositioning.
CONCLUSION:Both toric IOL had good rotational stability and effective in reducing pre-existing corneal astigmatism.Based on the mean axis deviation and the number IOLs rotating 15 degrees or more, the AcrySof showed statistically better stability.
