| مستخلص: | Purpose: To evaluate the influence of a capsular tension ring (CTR) on rotational stability, decentration, tilt, and axial stability of an 11.0-mm plate haptic intraocular lens (IOL). Design: Intraindividual, randomized, double-masked, controlled clinical trial. Participants: Patients scheduled for sequential same-day bilateral cataract surgery. Methods: All patients were randomized to receive a CTR and a plate haptic IOL in one eye and a plate haptic IOL in the fellow eye only. Intraocular lens axis assessment was performed at the end of surgery, 1 hour, 1 week, 1 month, and 6 months using a high-precision evaluation method. Decentration and tilt of the crystalline and pseudophakic lenses were assessed before surgery and at 1 week and 6 months using an anterior segment OCT. Main Outcome Measures: Rotational stability from the end of surgery to 6 months and at all follow-up visits, decentration and tilt at 6 months, and differences in axial shift between 1 week and 6 months. Results: One hundred thirty eyes of 65 patients were included in the study. Absolute rotation from the end of surgery to 6 months was 2.8 ± 3.9° and 3.2 ± 5.3° for the CTR and control groups, respectively (P = 0.613). Intraocular lens decentration and IOL tilt at 6 months were 0.29 ± 0.1 mm and 0.24 ± 0.1 mm and 6.7 ± 2.8° and 5.6 ± 1.6° for the CTR and control groups, respectively (P = 0.058; P < 0.01). A posterior IOL shift of 0.31 ± 0.31 mm and 0.19 ± 0.14 mm was observed in the CTR and control groups, respectively. Conclusions: Concomitant implantation of a CTR and a plate haptic IOL did not improve the overall rotational stability of the IOL compared with the control group. Against expectations, higher values of decentration, tilt, and axial shift were observed in the CTR group. The simultaneous use of a CTR and a plate haptic IOL in the absence of zonular weakness at the time of cataract surgery should be considered with caution.
