Overview
Aim:
The aim of the retrospective study was to establish the frequency of the posterior lens capsule opacification after the cataract surgery and artificial intraocular lens (IOL) Acri.Smart 46S (Acri.Tech Zeiss) implantation.
Material and methods:
The study group consisted of 72 eyes (30 men and 28 women), their average age was 65.4 ± 8.4 years, with performed cataract surgery and implanted IOL Acri.Smart 46S (Acri.Tech Zeiss). After the average period of 32.4 ± 7.3 months after the surgery, the patients underwent the examination with refractive error measurement, uncorrected and best-corrected visual acuity for far, and posterior lens capsule transparency examination with dilated pupils and with retroillumination photography taken by NIDEK EAS-100 device.
Results:
After the average follow-up period of 32.4 ± 7.3 months after the surgery, the refractive error was –0.32 ± 0.8 diopters and average cylindrical error –0.8 ± 0.6 Dcyl. The uncorrected visual acuity (UCVA) was 0.72 ± 0.3, and the best-corrected visual acuity (BCVA) 0.95 ± 0.2. The average diameter of the examined posterior capsule was 5.89 ± 2.1 mm, and the transparency of the posterior capsule was 98.41 ± 8.5 %. In two eyes (2.7 %) only, the YAG capsulotomy was performed.
Conclusion:
The IOL Acri.Smart is safe, easy to implant IOL, which meets the requirements of the microincision surgery. The IOL had very low incidence of posterior lens capsule opacification, and in two eyes (2.7 %) only the YAG capsulotomy was performed.
