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.

Objectives: The aim of this study was to assess the clinical outcomes, predictability of results, efficiency of astigmatism correction, and rotational stability of the Bi-Flex 677TAY (Medicontur Medical Engineering Ltd., Zsámbék, Hungary) monofocal toric intraocular lens (IOL) designed for cataract patients with astigmatism. Methods: The IOLs were implanted either mono- or binocularly, following routine cataract surgery. Visual and refractive outcomes, as well as off-axis rotation were assessed throughout a 1-year follow-up period. All clinical data for this work were collected retrospectively. Vector analysis based on the Alpins method was performed to assess the efficiency of astigmatism correction. Results: No complications or adverse events occurred during surgery or the follow-up period. IOL implantation brought 88% of eyes into the ±0.50 D, and 100% into the ± 1.00 D range compared to the target spherical equivalent refraction, emmetropia. Astigmatism correction brought similar results: 94% of eyes had a residual cylindrical error of not higher than ±0.50 D, and 97% were within ±1.00 D. Vector analysis resulted in a correction index of 0.96 and a difference vector of 0.17. Both refractive and visual outcomes showed long-term stability. During the 12-month follow-up period, no eyes had a rotation of >5°. Absolute rotation after 1 year was 1.42 ± 1.89° (median = 0°), while signed rotation was 1.06 ± 2.12° (median = 0°). Conclusion: The Bi-Flex 677TAY monofocal toric IOL, designed by Medicontur Medical Engineering Ltd., represents an efficient and safe solution for cataract patients with astigmatism. Clinical and refractive outcomes are predictable, and rotational stability ensures long-term visual comfort.
