Comparison Of 1- And 3- Year Capsulotomy Rates Of Alcon Clareon® Sy60wf And Alcon Acrysof Iq® Sn60wf, Single Site Single Surgeon Registry Study

This retrospective registry study compares Nd:YAG capsulotomy rates of two Alcon IOLs, Alcon Clareon® SY60WF and Alcon Acrysof® IQ SN60WF.

Medilaser Silmaasema, Cor Group, Jyvaskyla, Finland, and Department of Ophthalmology, Central Finland Central Hospital, Jyvaskyla, Finland.

Cataract surgeries were performed by single surgeon in single site in Medilaser Silmaasema. All surgeries were done with the same device Alcon Infinity®, and Alcon Provisc® viscoelastic was used.  Nd:YAG capsulotomy rates were calculated from the registry of Central Finland Central Hospital, which purchased cataract surgeries and performed Nd:YAG capsulotomies. Alcon Acrysof® IQ SN60WF IOLs were implanted to 1687 eyes (1072 patients, age 76.5 years, 409 males) until 5/2017. Alcon Clareon® SY60WF IOLs were implanted to 2033 eyes (1241 patients, age 76.6 years, 479 males, p = ns between groups) until 12/2018. Group comparison was done with chi-square test.

In 1-year follow-up, 82 (4.0%) Nd:YAG capsulotomies were done in Clareon® group and 86 (4.9%) in Acrysof® IQ group, p=0.338.  In 3-year follow-up, cumulation of 283 (13.9%) Nd:YAG capsulotomies were done in Clareon® group and 277 (16.4%) in Acrysof® IQ group, p<0.03.

In this single surgeon single site study, the Alcon Clareon® SY60WF presented lower Nd:YAG capsulotomy rates compared to Alcon Acrysof IQ® SN60WF after 3 years follow-up. This study may help to judge total costs of cataract surgery and secondary cataract treatment of these two IOLs.
