Comparison of the Results of Retropupillary Iris Claw Lenses and Scleral Fixated Intraocular Lenses in Aphakic Patients

Abstract

ABS TRACT Objective: The aim of the study was to compare outcomes following the use of retropupillary iris-claw lenses (ICLs) and scleral fixated intraocular lenses (SFIOLs) in aphakic patients after cataract surgery. Material and Methods: Nineteen eyes with secondary lens implantation were included in this study. The best corrected visual acuity (BCVA) was measured preoperatively. The anterior segment was evaluated using slit lamp biomicroscopy and dilated fundus examination was performed. Intraocular pressure (IOP) was measured. Central macular thickness (CMT) was determined with the RTVue-100® Fourier-Domain Optical Coherence Tomography (Optovue Inc, Fremont, USA). Endothelial cell count was evaluated using CellChek XL® specular microscopy (Konan Medical, Hyogo, Japan). The measurements were repeated in the first week, first month, and at three months, postoperatively. Results: Sixty-three per cent of the study participants were men, with a mean age was 68.11 years. A statistically significant difference was not observed between the two groups with regard to BCVA and IOP. The increase in CMT in the first week and first month was statistically significant in the group in whom retropupillary ICL were implanted. Endothelial cell loss was 9.77±3.93% in the retropupillary ICL group and 6.51±4.74% in the SFIOL group. One patient in each group developed an epiretinal membrane. Cystoid macular edema (CME) was detected in one patient who underwent retropupillary ICL implantation. Conclusion: Both retropupillary ICL and SFIOL implantation were found to be successful and safe in aphakic patients. A statistically significant difference was not observed between the two groups regarding endothelial cell loss over short-term follow-up. An increase in CMT was detected early period in the retropupillary ICL cases.
