DOI : 10.37844/glauc.cat.2021.16.15 Purpose: To investigate prevalence and biometric characteristics of long anterior zonule in cases underwent phacoemulsifi cation surgery.

Materials and Methods: We retrospectively reviewed charts of 693 consecutive patients (777 eyes) underwent phacoemulsifi cation surgery by single surgeon (FÖ) at Ophthalmology Department of Health Sciences University, Kütahya between January 2018 and October 2019.

Results: Long anterior zonule (LAZ) was detected in 8 cases (1.15%) during surgery, 7 of which had bilateral LAZ. Of the cases with LAZ, 3 were women and 5 were men with mean age of 76.5±7.11 years. In the eyes with LAZ, mean spherical equivalent was found as +0.95±2.15 diopter whereas mean intraocular pressure as 17.73±3.33 mm Hg, mean axial length as 22.70±1.15 mm, mean keratometry as 44.02±2.46 diopter, mean anterior chamber depth as 2.90±0.21 mm, mean central corneal thickness as 553.84±44.14 ?m and mean limbus-limbus distance as 11.68±0.36 mm. The mean power of intraocular lens implanted was 23.11±2.49 diopter. In addition, pigment dispersion was detected in 3 and posterior embryotoxon was detected in 1 case with LAZ. A notch in the capsulorhexis line was developed only in one patient while passing through the LAZ region during capsulorhexis stage no problem was experienced in the later stages of surgery. There was no postoperative complication in any of the cases with a mean follow-up 7.36±6.87 months.

Conclusion: In our study, eyes with LAZ tended to be hyperopic with shorted axial length in agreement with previous studies. In particular, capsulorhexis should be performed meticulously since unexpected tears may occur in the capsule. Keywords : Long anterior zonule, Ocular characteristics, Phacoemulsifi cation
