Effect of Toric Intraocular Lens Implantation on Astigmatism in Cataract Surgery

Abstract Background: Both femtosecond laser-assisted arcuate keratotomy (FS-AK) and toric intraocular lens (IOL) implantation were effective in correction for eyes with corneal astigmatism. The objective of this study was to evaluate the postoperative refractive outcomes of patients receiving femtosecond laser-assisted cataract surgery (FLACS) with FS-AK and patients receiving standard phacoemulsification with toric intraocular lens implantation Methods: This retrospective study reviewed the postoperative outcome of patients undergoing FLACS with FS-AK (FS-AK group) and patients undergoing standard phacoemulsification with toric IOL implantation (toric IOL group). The main outcome measures were bare and corrected visual acuities, keratometric and refractive astigmatism, and vector analysis.Results: The FL-AK group included 41 eyes with preoperative keratometric astigmatism of −1.64 diopters (D) ± 0.42 (standard deviation), and the toric IOL group included 53 eyes with preoperative keratometric astigmatism of −2.29 ± 0.91 D (P < 0.001). Postoperative refractive astigmatism was comparable between the two groups. Postoperative bare vision was significantly better (P = 0.005) and corrected visual acuity was marginally better in the toric IOL group than in the FS-AK group (P = 0.051). The absolute angles of error were 9.95 ± 9.57 degrees and 5.08 ± 4.94 degrees (P = 0.02) in the FS-AK and toric IOL groups, respectively.Conclusion: Both FLACS with FS-AK and standard phacoemulsification with toric IOL implantation represent safe and effective methods for astigmatism correction at the time of cataract surgery. Standard phacoemulsification with toric IOL implantation achieves better visual outcome than combined FLACS and FS-AK at 6-month follow up.

ABSTRACT We report cataract surgery with toric intraocular lens implantation for the management of senile cataract combined with pellucid marginal degeneration. A 72-year-old man with bilateral senile cataract and significant against-the-rule astigmatism sought counseling for blurry vision and glare, mostly in the right eye. Based on ophthalmic examination and corneal topography, a diagnosis of pellucid marginal degeneration and cataract was made. Since visual acuity and refraction had been stable in the past 3 years, the patient underwent cataract extraction and implantation of a custom-designed toric posterior chamber intraocular lens. Postoperative follow-up of 1.5-year demons- trated marked improvement in visual acuity, stable refraction and patient satisfaction. This treatment for pellucid marginal degeneration offers the simplicity of regular cataract surgery, and avoids the known complications of keratoplasty and other corneal surgical manipulation for the management of pellucid marginal degeneration.
