Comparison of the clinical outcomes of Eyecryl™ and Tecnis® toric intraocular lenses: A real-world study

Abstract

Purpose: To compare the postoperative uncorrected distance visual acuity (UDVA) and refractive outcomes of cataract patients with astigmatism following implantation of Eyecryl^™ and Tecnis® toric intraocular lenses (IOLs).

Methods: We conducted a single-center, retrospective study including patients who had undergone phacoemulsification and implantation with either Eyecryl^™ toric (Group 1) or Tecnis® toric (Group 2) IOL. The primary outcome measures included postoperative UDVA and residual astigmatism at 3 months. The secondary outcome measure was IOL misalignment >10° throughout the follow-up period.

Results: One hundred and eight eyes of 76 patients (44 males and 32 females) were analyzed. Twenty-nine patients (38 eyes) received Eyecryl^™ toric IOL (Group 1), and 47 patients (70 eyes) received Tecnis® toric IOL (Group 2). Groups 1 and 2 showed a mean postoperative logMAR UDVA of 0.09 ± 0.11 and 0.06 ± 0.09, respectively, at 3 months (P = 0.114). In both groups, all the eyes achieved a postoperative UDVA of ≤0.3 logMAR. The postoperative residual astigmatism of group 1 and group 2 was -0.29 ± 0.34 D and -0.16 ± 0.27 D, respectively (P = 0.038). Postoperative astigmatism was within ± 1.00 D in all the eyes. No eyes had an IOL misalignment >10° throughout the follow-up period.

Conclusion: Both Eyecryl^™ and Tecnis® toric IOLs provided significant improvement in uncorrected visual acuity and astigmatism correction postoperatively. The Tecnis® toric IOL provided statistically significant lower residual astigmatism than Eyecryl^™toric IOL. However, the difference in postoperative astigmatism between the two IOLs was clinically insignificant.
