Safety and effectiveness of Eyecryl toric intraocular lenses in the correction of astigmatism post-phacoemulsification: A retrospective study

Objective: This study evaluates the clinical efficacy as well as safety of Eyecryl toric intraocular lenses (tIOLs) for addressing corneal astigmatism in patients undergoing phacoemulsification for cataract removal. Methods: A total of 107 eyes from 91 patients (44 males, 47 females; mean age 63 ± 9.96 years) underwent cataract extraction followed by Eyecryl tIOL implantation. Inclusion criteria required corneal astigmatism >1.0D with no contraindications for tIOLs, while exclusion criteria included irregular astigmatism, prior intraocular surgeries, small pupils, and non-cataract ocular pathologies. Pre-operative assessments included visual acuity, keratometry, and ocular biometry. Follow-ups were conducted on day 1, week 1, month 1, and year 1. Data were analyzed using the signed-rank and Alpins method for vector analysis. Results: Post-surgical refractive astigmatism significantly decreased to 0.03 ± 0.15 D from 1.73 ± 0.70 ( P < 0.0001) of pre-operative baseline. Best-corrected visual acuity (BCVA) LogMAR improved consistently at all follow-ups, and uncorrected visual acuity (UCVA) showed significant enhancement at 1 year ( P < 0.0001). Vector analysis showed astigmatic correction (target-induced astigmatism vector [TIA] of 1.22 diopter (D) and surgically induced astigmatism [SIA] vector 1.23 D at 92°, difference vector [DV] of 0.02 D, and correction index [CI] of 1.00). The rotational stability of the IOLs was excellent, with ~90% of eyes showing 0–5° rotation at the final follow-up and 8.41% exhibiting 6–10° rotational displacement. A single case of rotation >10° was observed, with no other instances of instability during the 1-year follow-up. No intraoperative or post-operative complications were reported. Conclusion: Eyecryl tIOLs demonstrated strong safety, efficacy, and rotational stability in correcting corneal astigmatism post-phacoemulsification. The study highlights significant improvements in visual acuity and refractive outcomes with minimal adverse events or intraoperative complications.
