BERLIN — A global study showed that an angle-supported phakic IOL is efficacious and improved patient quality of life, experts said here.

"Bilateral implantation of the AcrySof phakic angle-supported lens (Alcon) reduced the dependence on corrective lenses in patients with high myopia and improved quality of life ... and certainly improved their satisfaction with uncorrected vision," Stephen S. Lane, MD, said at the European Society of Cataract and Refractive Surgeons meeting.

Ralf Gerl, MD, presented the scientific results of the 3-year international study that looked at 104 patients implanted with the IOL, and Dr. Lane presented the quality-of-life and functional status assessment.

Dr. Gerl showed that 80% of the mild or high myopes were 20/20 or better, and 100% were 20/40 or better, with nearly unchanged endothelial cell counts. Ten patients (2.8%) required IOP lowering, and seven patients (1.9%) developed cataract.

Dr. Lane presented data gathered with the Refractive Status and Visual Profile survey conducted at baseline and 3 months, 6 months and 1 year after surgery.

Overall, on the Refractive Status and Visual Profile scale of 0 to 100, with 0 being perfect, patients preoperatively scored their quality of life at 27.5. One year after the procedure, their average score was 17.9.

Preoperatively, 100% of the patients used lenses; postop, 79.3% were lens-free. About 96% of patients said they would undergo the procedure again if given the choice, Dr. Lane said.

I do feel, personally having a 10-year relationship with this lens, that it really sets a successful correction for moderate to high myopia. It’s extremely easy to implant, much easier than all the other phakic IOLs that we’ve used. … Refraction is stable over time, producing excellent visual acuities. Best corrected visual acuities, as expected, maintain or improve. And endothelial cell density both in the center and in the periphery is maintained, so there is no significant endothelial cell loss. There are also no other incidents regarding safety.
