RESUMO
@#<p style="text-align: justify;"><strong>OBJECTIVE:</strong> To compare the rotational stability and cylinder reduction of different toric intraocular lenses (IOLs).<br /><strong>METHOD:</strong> This was a prospective, cross-sectional study of 68 eyes that had at least 0.75 diopters (D) of corneal astigmatism prior to cataract surgery and were at least 3 months post-toric IOL implantation (Envista, AcrySof, FineVision). Patients recruited underwent visual acuity testing, manifest refraction, pupil dilation, and toric IOL axis determination. Actual axis position was obtained and compared to the intended axis calculated from the tonic IOL calculator. Any difference between the two was considered an axis deviation. Main outcome measures were postoperative deviation of the IOL axis from the intended axis, uncorrected distance visual acuity (LIDVA), best corrected distance visual acuity (BCDVA), manifest refraction, and cylinder reduction.<br /><strong>RESULTS:</strong> There was no significant difference in the rotational stability of the three different types of toric IOLs (p=0.95). Mean axis deviation for .AcrySof, Envista, and FineVision were 2.43, 2.66, and 2.75 degrees, respectively. There was a significant decrease in the cylinder from preoperative to postoperative levels for all groups (p=0.00 for Envista, p=0.03 for AcrySof, and p=0.00 for Fine-Vision). There were significant improvements in the mean UCVA and BCDVA after cataract surgery and implantation of toric IOLs for all three groups.<br /><strong>CONCLUSION:</strong> The three IOL platforms (AcrySof, Envista, and FineVision) showed good rotational stability and significant cylinder reduction:Visual and refractive outcomes improved after surgery.<br /><br /></p>
