Foldable Intraocular Lens Aspheric Optical Design
Foldable IOLs have helped alter the face of cataract surgery by
improving healing time, limiting complications and making
phacoemulsification the standard procedure over extracapsular
surgery, all in the span of 2 decades.
At first, the new lenses and procedures were not widely accepted at
their advent in the mid-1980s, physicians said. PMMA IOLs were the
standard IOLs used at that time, and they were typically inserted
through 5-mm to 7-mm incisions after extracapsular surgery. More
than 20 years later, most surgeons now implant foldable acrylic or
silicone IOLs after phaco, and PMMA lenses are used only in special
cases.
The main advantages of the foldable IOL are the smaller incision
size – 3 mm or smaller – and faster wound healing time. Several
companies have produced their own versions of the lens, from
silicone versions to the later development of acrylic IOLs.
