PURPOSE: This study focuses on the analysis of the rotational stability after implantation of a biconvex aspheric toric monofocal intraocular lens (IOL) with a double C-loop haptic-design in eyes with normal versus high axial lengths.
METHODS: This was a prospective comparative study including 150 eyes with corneal astigmatism (≥0.75D) implanted with the biconvex aspheric monofocal PODEYE toric IOL and assessed up to 1 year after surgery. From these 150 eyes, 81 and 69 eyes belonged to normal (≤23.9mm) and high (≥24mm) axial lengths, respectively. About 4-6 and 11-13 months postoperatively, refraction and rotational stability of the PODEYE toric IOL were evaluated to find possible differences among both groups.
RESULTS: At the last postoperative-visit, 74.07% of eyes were within ±0.50D and 95.06% of eyes were within ±1.00D of the target-refraction for the normal group and 92.75% and 100% for the high axial length group, respectively. For the normal group, 77.78% and 96.30% of eyes had a postoperative refractive cylinder of ≤0.50D and ≤1.00D, respectively; and for the high axial length group these percentages were 84.05% and 100%, respectively. About 81.84% of eyes in the normal and 94.20% of eyes in the high axial length group were <5 degrees of the intended axis. The mean IOL rotation was 2.93 ± 2.48 degrees in the normal axial length group, and 2.17 ± 1.73 degrees in the high axial length group. Based on the mixed ANOVA results, there is no evidence of a significant difference in IOL rotation over time, nor is there evidence that axial length plays a statistically significant role in rotational stability between 4-6 and 11-13 months postsurgery. Both groups exhibited similar and stable rotation outcomes.
CONCLUSION: Our results reveal that the biconvex aspheric monofocal PODEYE toric IOL with double C-loop haptic-design shows excellent rotational stability without significant differences between eyes with normal and high axial lengths.
