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.
