Yamane technique provides stable IOL fixation in pediatric eyes

FRANKFURT, Germany — In children’s eyes with insufficient capsular support, intrascleral IOL fixation with the Yamane technique leads to good visual outcomes and few intraoperative and postoperative complications.
At the ESCRS winter meeting, Vladimir Pfeifer, MD, presented the results of this technique in 19 eyes of children aged between 4 and 14 years, with a mean follow-up of 3 years and one case up to 6 years. Nine were idiopathic ectopic lens cases, eight were secondary to Marfan syndrome, and two were secondary to homocystinuria.

Best corrected visual acuity was 20/100 preoperatively and improved postoperatively to 20/30, with many patients achieving 20/20. Only one patient lost one line, and 95% had improved vision. Mean postoperative astigmatism was 1.37 D.
“There were no intraoperative complications. One case of haptic dislocation and lens tilt required surgical repositioning 51 months after the surgery. We saw the tilt earlier on [ultrasound biomicroscopy], and it always showed us that the haptic was still touching the sclera. But later on it dislocated, and we had to reposition it,” Pfeifer said.
One optic capture required repositioning with peripheral iridectomy, while other occasional episodes of optic capture occurred, disappearing spontaneously with mydriasis.
“Longer follow-up is required to assess long-term stability because of their long life span,” Pfeifer said.
