PURPOSE: To evaluate the results of AcrySof Toric intraocular lens (Alcon) implantation to correct pre-existing astigmatism and rotational stability in patients having cataract surgery or not.
METHODS: Retrospective study three surgical teams, between February 2009-August 2010, included 37 eyes with more than 1 diopter (D) of preexisting corneal astigmatism having or not cataract surgery.
RESULTS: Rotation at 6 M post-op: 32 patients (87%)--> rotation between aprox. 0-5 degrees, 4 patients (11%)--> rotation between A 5-10 degrees, 1 patient (2%) rotation of A 20 degrees. The mean refractive cylinder decreased significantly after surgery: 34 (91.90%) of cases between 0.25-0.75 D--2 (5.40%) of cases 1.5 D--1 (2.70%) of cases > 1.5 D.
CONCLUSIONS: In conclusion the results indicate that TheAcrySof Toric IOL is a viable option of preoperative corneal astigmatism in carefully selected cases. The Toric IOL showed good rotational stability The most frequent cause of turnover is the: viscoelastic left in the capsular bag (early rotation); fibrosis of the bag (late rotation).
