Piggyback IOL enhances postop refractive outcomes

A piggyback IOL corrected unexpected visually significant postoperative refractive error and astigmatism and reduced spectacle dependence for distance in pseudophakic eyes, according to a study.
The retrospective analysis included 15 eyes of 13 patients implanted with the Sulcoflex IOL (Rayner Intraocular Lenses). Three eyes were implanted with an aspheric model and 12 eyes were implanted with a toric model. Refractive outcomes and corrected and uncorrected distance visual acuity were evaluated at 1 week and 1, 3, 6 and 12 months postop.
Uncorrected distance visual acuity improved from a preop mean of 20/55 to 20/32 or better in all eyes and 20/20 or better in 10 eyes. No patients lost any lines of corrected or uncorrected distance visual acuity.
Mean spherical equivalent refraction at 3 months postop was −0.15 ± 0.28 D. All patients were within 1 D of attempted correction, and 93% were within 0.5 D. Mean astigmatism was −1.45 ± 0.98 D preop and −0.50 ± 0.57 D postop.
There were no intraoperative complications, and none of the lenses required repositioning.
“Appropriate patient selection, accurate preoperative measurements, good intraoperative technique, and careful postoperative management can result in excellent outcomes with minimal risk of complications,” the study authors said.
The study was limited by its retrospective nature and small cohort size, the authors noted.
