Abstract
Femtosecond laser arcuate keratotomy (FS-AK) and toric intraocular lens (IOL) implantation are effective for the correction of eyes with corneal astigmatism. In this study, the postoperative refractive outcomes of patients receiving femtosecond laser-assisted cataract surgery (FLACS) with FS-AK and patients receiving standard phacoemulsification with toric IOL implantation were evaluated. This retrospective study reviewed the postoperative outcomes of patients undergoing FLACS with FS-AK (the FS-AK group) and patients undergoing standard phacoemulsification with toric IOL implantation (the toric IOL group). The main outcome measures were uncorrected and corrected visual acuities, keratometric and refractive astigmatism, and vector analysis. The FS-AK group included 41 eyes with preoperative keratometric astigmatism of - 1.64 ± 0.42 diopters (D), 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. Compared with the FS-AK group, postoperative uncorrected visual acuity was significantly better (P = 0.005) and corrected visual acuity was marginally better in the toric IOL group (P = 0.051). The absolute angles of error were 9.95° ± 9.57° and 5.08° ± 4.94° (P = 0.02) in the FS-AK and the toric IOL groups, respectively. Both FLACS with FS-AK and standard phacoemulsification with toric IOL implantation are safe and effective methods for astigmatism correction during cataract surgery. Standard phacoemulsification with toric IOL implantation achieves better visual acuity than FLACS with FS-AK at the 6-month follow-up.
Highlights
Both femtosecond laser-assisted arcuate keratotomy (FS-AK) and toric intraocular lens (IOL) implantation were effective in correction for eyes with corneal astigmatism
During a 15-month study period, combined femtosecond laser-assisted cataract surgery (FLACS) and FS-AK were performed in 41 eyes of 36 patients, and standard phacoemulsification with toric IOL implantation was done in 53 eyes of 47 patients
Our results showed comparable postoperative refractive astigmatism at 1 month follow-up and 6 months follow-up between these two groups
Summary
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. Postoperative residual astigmatism is one of the leading causes of ordinary visual outcomes and poor patient satisfaction [1]. Various techniques have been employed to manage corneal astigmatism during cataract surgery, including limbal relaxing incision, peripheral corneal incision, and toric intraocular lens (IOL) implantation [3, 4]. With advances in femtosecond laser technology, femtosecond laser-assisted arcuate keratotomy (FS-AK) was adopted to correct astigmatism [5]
