Cataract Surgery in Eyes with Low Corneal Astigmatism: Implantation of the Acrysof IQ Toric SN6AT2 Intraocular Lens

Purpose: to assess the refractive and visual outcomes following cataract surgery and implantation of the acrysof iq toric sn6at2 intraolcular lens (iol) (alcon laboratories,inc.,fort worth,tx,usa) in patients with low corneal astigmatism. methods: this study is a retrospective,consecutive,single surgeon series of 98 eyes of 88 patients (with low preoperative corneal astigmatism) undergoing cataract surgery and implantation of the acrysof iq toric sn6at2 iol. postoperative measurements were obtained 1-month postsurgery. main outcome measures were monocular distance visual acuity and residual refractive astigmatism. results: mean preoperative corneal astigmatic power vector (apv) was 0.38±0.09 d. following surgery and implantation of the toric iol,mean postoperative refractive apv was 0.13±0.10 d. mean postoperative distance uncorrected visual acuity was 0.08±0.09 logmar. postoperative spherical equivalent refraction (ser) resulted in a mean of -0.23±0.22 d,with 96% of eyes falling within 0.50 d of the target ser. conclusion: the acrysof iq toric sn6at2 iol is a safe and effective option for eyes undergoing cataract surgery with low levels of preoperative corneal astigmatism.
