WAILEA, Hawaii — The IC-8 Apthera IOL is a reliable option for managing irregular corneas, as long as the right candidates are selected, according to a presenter here at Hawaiian Eye 2024.
“You can't overextend this lens,” Eric D. Donnenfeld, MD, said. “It is great for complex eyes, but really complex eyes don't work at all.”
Donnenfeld said that while he uses the IC-8 Apthera IOL (Bausch + Lomb) in patients with regular corneas, particularly those who may have undergone successful phakic monovision or those with a corneal astigmatism of 1.5 D or less of corneal astigmatism, he especially recommends it for patients with irregular corneas, provided they are the right candidate.
“This is where this lens has become the linchpin in my practice,” he said.
According to Donnenfeld, the IOL can correct up to 0.75 D of sphere and 1.5 D cylinder and is quite “forgiving” as an IOL.
“That’s what I want in my surgery,” he said. “I want a forgiving lens.”
Donnenfeld recommended the IOL for patients who want additional near vision but are not candidates for a trifocal IOL. He also recommended the lens for individuals with – 0.75 D in their non-dominant eye and patients with near vision levels of J1 to J2.
Other solid patient candidates with irregular corneas who are good candidates for the small aperture lens include patients who previously have undergone penetrating keratoplasty or LASIK who have high myopia, hyperopia or a decentered ablation.
“For me, this is the single best solution I have for irregular corneas in challenging eyes,” he concluded. “But, you can't overuse this lens, and patient selection is very important."
