Early capsular bag contraction with haptic dislocation following implantation of a flexible hydrophilic acrylic “psuedoaccomodating” IOL

Comment: Near vision was easier to achieve with those who were originally myopic (thinner IOL). Targeting mini-monovision of -0.75 in the non-dominant eye improved the near vision capability. Pushup exercises were useful in the near term, but had little effect once capsular fibrosis was well established
Comment: Capsular fibrosis was common, as expected with hydrophilic acrylic IOLs. The rate of early capsular fibrosis suggests that more than 50% will ultimately require YAG laser capsulotomy.
Comment: The soft haptics were easily compressed, bending inwards along the horizontal part, migrating centrally, often under the optic, causing lens tilt and occasionally pushing the optic out of the capsular bag. Vision was degraded by induced astigmatism as well as by capsular opacity. All cases responded well to surgery and, to date, have remained well positioned with a satisfactory return of vision.
Comment: I no longer offer this IOL to my patients because any benefit of near vision now seems overwhelmed by the possible need for revision surgery.
