Abstract
INTRODUCTION: To compare the short-term visual and aberrometric outcomes and the long-term capsulotomy incidence in a cohort of patients receiving IOLs with similar structural profile but with a hydrophobic matrix in one eye (PHOB group) and a hydrophilic matrix in the other one (PHIL group). METHODS: In this retrospective, contralateral study, 26 patients sequentially undergoing phacoemulsification were implanted as mentioned above. Refraction and aberrometry were evaluated 6 months after surgery. For the quality of vision, the Hartmann-Shack optical aberration, Double-Pass Modulation Transfer Function (MTF), contrast sensitivity, and dysphotopsia results were compared. Capsulotomy was ascertained and dated by medical chart revision or phone call. RESULTS: All the considered quantitative and qualitative visual parameters tested statistically comparable between PHIL and PHOB group. After 5 years, four patients (16.7%) in the PHOB group and five patients (20.8%) in the PHIL group underwent a Nd:YAG posterior capsulotomy (P > 0.5). CONCLUSION: In this contralateral comparative study, the hydrophobic and hydrophilic matrix of the IOL similarly influenced the visual and aberrometric outcomes. Also the long-term laser capsulotomy incidence did not statistically differ between groups. The posterior IOL profile, rather than matrix hydrophilia, could consistently influence the posterior capsule opacification.
