WASHINGTON — Decentration and dislocation are still the most common reasons for lens removal, according to an annual study of foldable IOLs.

Nick Mamalis, MD, author of the study, said these findings on decentration have been “consistent for the 7 years of our survey.” He presented results from the 2004 survey here at the annual meeting of the American Society of Cataract and Refractive Surgery.

Dr. Mamalis said that to prevent decentration and dislocation, good surgical techniques are essential, and surgeons should “make sure that the lens is well centered.”

He added other complications depend upon what type of IOL was used. However, he said “ongoing vigilance is needed” regarding new IOL materials.
