Piggybacking with the Add-On IOL is safe, efficient and reliable for correcting pseudophakic refractive errors.

A team led by Dr B. Basarir, Beyoglu Eye Education and Research Hospital, Istanbul, Turkey, included 10 eyes of 10 patients with pseudophakic refractive errors. All patients were targeted to achieve a range of refraction between -0.50 to +0.50 D.

Preoperative and postoperative outcome measures included uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), endothelial cell count (ECC), anterior chamber depth (ACD), the distance between intraocular lenses and contrast sensitivity measurements under mesopic, scotopic, and scotopic with glare conditions.

The mean preoperative and postoperative UDVA was 0.133±0.12 and 0.73±0.27, respectively. Mean preoperative and postoperative CDVA were 0.77±0.26 and 0.79±0.27, respectively.

The findings revealed the mean preoperative and postoperative ACD to be 3.87±0.91 mm vs. 3.58±1.05 mm, respectively. All patients achieved the target refractive range of -0.50 D to +0.50 D and no complications were recorded.
