Purpose

To evaluate the results obtained with toric intraocular lenses (IOLs) in the correction of preoperative corneal astigmatism in patients undergoing cataract surgery.

Methods

A retrospective, noncomparative case series of 103 eyes of 89 patients who underwent phacoemulsification and posterior chamber IOL implantation.

AcrySof® Toric IOL (models SN60T3, SN60T4, and SN60T5; Alcon Laboratories, Inc., Fort Worth, TX) were used in all cases.

Pre-op corneal cylinder >1.50 Diopters in all eyes.

Methods

Routine coaxial phacoemulsification technique performed by the same surgeon (L. W. Lu).

IOL inserted through 2.8 mm incision.

AcrySof® Toric IOL Web Based Calculator used in all cases with incision location at steep K axis.

Methods

Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) and manifest refraction were analyzed in all eyes prior to surgery and 3 and 12 weeks following cataract surgery.

Results

At 3 months follow-up, 95% of eyes were within ±1.00 diopter (D) of emmetropia and 85% of eyes had an UCVA of 20/30 or better.

Regarding the results achieved in the first eye, 87 of the 89 patients asked for a toric IOL implantation for the second eye.

Conclusion

Our results indicate that posterior chamber toric IOL implantation is a predictable option to correct preexisting corneal astigmatism in cataract patients undergoing a routine phacoemulsification procedure.

Notes

103 eyes from 89 patients were included instead of 113 from 99 as originally noted in the abstract because corneal incisions (LRI or CCI) were also performed in 10 cases; these were excluded from the study.

Surgeries performed between 2006 and 2007, not since 2004 as noted in the abstract (typing error).
