Iridocapsular lenses versus iris-clip lenses: comparison of the results and complications of 100 of each

Abstract

The results and complications of implantation of 100 iridocapsular and 100 iris-clip lenses are evaluated. The follow-up period for the first group varied from one to 25 months (mean 12 months) and from one to 43 months (mean 27 months) for the second group. I performed all of the operations and most of the follow-up examinations. Of the patients with iridocapsular lenses, 86 percent and of those with iris-clip lenses, 87 percent obtained a visual acuity of 0.5 (6/12) or better. Binocular vision, positive depth perception, and a small degree of aniseikonia (3% or less) are evident optical benefits. The complicatioons most frequently necessitating a second operation were retained lens material (17%) and repositioning the pseudophakos (6%) in the iridocapsular group. The four-loop lenses caused fewer problems; in one case, posterior luxation necessitated its removal.
