Purpose
To assess the overall outcome of the ciliary sulcus piggyback add-on IOL implantation on previously pseudophakic patients who pursue a spectacle-free option after IOL surgery.
Setting
Anterior Segment Surgery Service at the Centro de Ojos Quilmes, Quilmes, Buenos Aires Province, Argentina
Methods
Pseudophakic patients who underwent phacoemulsification surgery using a monofocal in-the-bag IOL. All eyes underwent a piggyback IOL implantation of an A4 AddOn IOL in the ciliary sulcus as a secondary procedure for pseudophakic patients pursuing a spectacle-free option. The BCVA, UIVA, and UNVA were evaluated. A pairedt-test and a Wilcoxon test were employed to assess significance. The D’Agostino-Pearson normality test was used to assess normality.
Results
Seven eyes were included in our study. A total of 4 (71.43%) were female, with a mean age of 58.33 ± 3.5 years (range 54–63; 95% CI 54.66, 62.01).
At the 3-month follow-up visit, the mean UNVA (logMAR) improved from 0.55 to 0.01 postoperatively (p = 0.015). The UIVA increased from 0.61 to 0.01 (p = 0.015). The mean UDVA did not differ significantly from the preoperative assessment.
Conclusions
A Multifocal piggyback IOL sulcus implant is a safe alternative for pseudophakic patients pursuing a spectacle-free option. This add-on platform provides optimal visual acuity and quality of vision at all distances. Nonetheless, further studies should support these results, including larger sample sizes and a long-term follow-up.
