Factors Associated With Residual Astigmatism After Toric Intraocular Lens Implantation Reported in an Online Toric Intraocular Lens Back-calculator

Although toric intraocular lenses (IOLs) have demonstrated considerable success in reducing astigmatism at the time of cataract surgery, residual refractive astigmatism remains in some patients. With early toric IOL calculators, aggregate results indicated that only approximately 70% of eyes implanted with a toric IOL had 0.50 diopters (D) or less of refractive astigmatism postoperatively.1 The advent of toric IOL calculators that incorporated consideration of posterior corneal astigmatism appears to have increased this number to near 80%.2,3 Although these percentages are significantly
