Purpose
To evaluate toric intraocular lens (IOL) rotational stability after cataract surgery with and without primary posterior continuous curvilinear capsulorhexis (PPCCC).
Setting
The prospective randomized controlled trial was conducted at Fuzhou University Affiliated Provincial Hospital in Fujian, China, between September 2024 and December 2024.
Methods
Thirty eight eyes of 28 adult patients were included with cataracts undergoing phacoemulsification cataract surgery with toric IOL implantation. Eyes were randomized into two groups: one group received cataract surgery combined with PPCCC (PPCCC group), and the other group received cataract surgery without PPCCC (NPCCC group). Toric IOL axis orientation and residual astigmatism were measured at 1 day, 1 week, 1 month, and 3 months postoperatively using the OPD-Scan III.
Results
No eye exhibited a toric IOL rotation exceeding 10°. There was no statistically significant difference in toric IOL axis misalignment between the PPCCC and NPCCC groups at 1 day, 1 week, 1 month, and 3 months (1.62° ± 1.69° vs. 1.35° ± 1.53°, 2.15° ± 1.47° vs. 1.77° ± 1.26°, 2.07° ± 1.76° vs. 2.55° ± 2.06°, and 1.80° ± 1.61° vs. 2.44° ± 1.75°, respectively; P > 0.05). Residual astigmatism was -0.37 ± 0.29 D at 3 months post-surgery. No statistically significant difference in residual astigmatism was found between the two groups at any postoperative time point (P > 0.05).
Conclusions
Cataract surgery involving PPCCC demonstrated comparable outcomes with conventional procedures regarding toric IOL rotational stability. PPCCC is a safe and effective option for cataract patients with toric IOL implantation.
