Clinical outcomes and rotational stability following implantation of Eyecryl toric intraocular lens – Results of a 12-months prospective study

Abstract

Purpose: To evaluate the clinical performance and rotational stability after implantation of Eyecryl Toric monofocal IOL following cataract surgery. Methods: Patients undergoing phacoemulsification for age-related cataract and satisfying the eligibility criteria were implanted with Eyecryl Toric IOL. All implantations were done under balanced salt solution. A marker-less system Callisto Eye (Carl Zeiss Meditec, Germany) was used to guide the intra-operative alignment of the toric IOL. Results: A total of 50 eyes from 39 patients with mean age of 68.2 ± 8.7 years were included in the study. At 12 months, 82% (41) eyes had cumulative UDVA of 20/20 or better. Post-op SE refraction accuracy was within ± 0.50 D for 94% ( n = 47) eyes and refractive cylinder accuracy was within ≤0.50 D in 98% ( n = 49) eyes. Average post-op rotation at 1 year was 4.06 ± 2.15 degrees. Eighty-four percent of eyes were within 5 degrees and 16% were within 6-10 degrees of intended axis. Two eyes required IOL re-positioning due to significant rotation of the toric IOL (>10 degrees), identified within the 1 st week after surgery. Conclusion: Eyecryl toric IOL demonstrated the ability to achieve a significant reduction in astigmatism, improved UDVA outcomes, high levels of spectacle independence, low rates of intra-operative injector related complications and good rotational stability at 12 months post-op.

Comparison of clinical outcomes of Eyecryl toric and Alcon toric intra-ocular lenses – A real world study

“…According to the findings of our study, patients with corneal astigmatism who had toric AcrySof and Eyecryl IOLs implanted after cataract surgery saw comparable visual results and astigmatism reduction, which are in line with similar studies. [ 1 4 9 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 ] Nevertheless, this study is the first to directly examine the results of a known international toric IOL, such as AcrySof toric, with those of an Indian-made toric IOL, Eyecryl, in a secondary center in South India. Post-operative UCVA at 1 month was comparable between the two toric IOLs.…”

“…An IOL rotation of more than 10 degrees post-operatively was discovered in up to 7% of eyes across several studies involving all commonly used toric IOLs, with a high axial length, a younger age, greater pre-surgical astigmatism, and with the rule astigmatism patients having the highest rotation within the first 10 days post surgery. [ 9 10 11 12 18 20 21 22 24 29 30 43 44 ] IOL rotation less than 10 degrees typically does not require re-surgery. It has been found that hydrophobic acrylic lenses have better rotational stability than other IOL materials.…”
