Aujla JS, Vincent SJ, White S, Panchapakesan J - J Ophthalmic Vis Res (2014 Jul-Sep)

Bottom Line: 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.The AcrySof IQ Toric SN6AT2 IOL is a safe and effective option for eyes undergoing cataract surgery with low levels of preoperative corneal astigmatism.

ABSTRACT

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.

Figure 1: Distribution of the postoperative difference in spherical equivalent refraction (SER) from the preoperative target SER, for 98 eyes implanted with the AcrySof SN6AT2 intraocular lens.

Mentions: Figure 1 displays the distribution of the difference in postoperative SER from the preoperative target SER for all eyes. Overall, 84% of patients achieved a postoperative SER within 0.25 D of the target, and when extended to within 0.50 D of the target, a 96% success rate was achieved. The mean postoperative SER of –0.23±0.22 D was not significantly different from the target SER calculated prior to surgery (-0.20±0.13 D, P=0.16).
