Purpose

To study the safety and efficacy of a new technique of phacoemulsification in eyes with Long Anterior Zonule (LAZ)

Setting

Sohag University - Department of ophthalmology

Methods

A retrospective inverventional case series of twenty eyes with clinically proven cataract and LAZ who have undergone cataract surgery in the period from 2016 to 2021 with least 12 months of follow up. The technique invloved the use of small sized continuous curvilinear caspulorhexis (CCC) at the Zonules free zone (ZFZ) then performing the phacoemulsification and insertion of Capsular tension ring before implanting a hydrophobic lens. All patients were followed up for at least one year with full slit lamp examination of the anterior segment including uncorrected and corrected distance visual (UCDVA,CVDA)CDV, lens centration, corneal endothelial cell count and presence or absence of surgery related complications.

Results

twenty eyes (twelve patients) were analyzed; the mean age of patients was 62.3 ± 3.4 years. The successful completion of a small sized capsulorhexis at the ZFZ in all of cases. There were no intraoperative complications . The mean post-operative CDVA was 0.05 ± 0.1 (logarithm of the minimum angle of resolution) at the 12th month follow up visit. The mean spherical equivalent was 0.19±0.7 D. Eyes within ±0.5 D and ±1.00 D of the target refraction were 65% and 85%, respectively.

Conclusions

Phacoemulsification in patients with LAZ can be safely and effeciently performed through a small sized Capsulorhexis at the ZFZ without sacrificing the zonules.with the implantation of CTR to prevent postoperative capsular phimosis.
