This study analyzed 70 eyes of 70 patients who underwent hydrophobic plate-haptic toric (VSY Acriva BB toric IOL) (n = 39 eyes) or hydrophobic C-loop haptic toric (Alcon AcrySof IQ toric IOL) (n = 31 eyes) IOL implantation between 2017 and 2024. Preoperative and postoperative uncorrected and corrected distance visual acuity (UDVA and CDVA), manifest refraction values and IOL rotation degrees were compared.

Both groups had similar age, gender, and follow-up time (p>0.05 for each). Preoperative UDVA, CDVA, spherical, cylindrical refractive values, corneal topographic astigmatism, horizontal visible iris diameter, anterior chamber depth, and axial length were also similar in both groups (p>0.05 for each). There were no significant differences in UDVA, CDVA, spherical, and cylindrical refractive values between the two groups at the postoperative 1st month and the last follow-up visit (p>0.05 for all). However, the mean degree of IOL rotation at the last visit was significantly higher in the C-loop haptic group (7.09 ± 7.11) compared to the plate haptic group (3.48 ± 3.69) (p=0.008).

Plate haptic toric and C-loop haptic toric IOLs yield comparable results in terms of visual acuity and refractive values. However, the plate haptic design offers superior stabilization and less rotation.
