Abstract
The gonioscopic appearances of 45 eyes that had undergone extracapsular cataract extraction with insertion of a Pearce Lasagap posterior chamber intraocular lens (group A) were compared with those of 45 eyes that had undergone the same procedure except for insertion of a Nova Curve Kratz posterior chamber lens (group B). Prominence of one or both loops was seen in 35 eyes (78%) of group A, with peripheral anterior synechiae (PAS) in 25 (55%). Prominence of one loop was seen in 14 eyes (31%) of group B, with PAS in 8 (18%) (P less than 0.001). Final visual acuity was comparable in both groups, 98% achieving 6/12 (20/40) or better. Although not statistically significant, the incidence of pigment dispersion, uveitis, discomfort and visual aberrations was greater in group A than in group B. We suggest that the apparent superiority of the Nova Curve Kratz lens in terms of the smaller incidence of loop prominence, as well as the reduced incidence of these other complications, is due to the fact that its haptic is inserted into the optic's edge rather than into the anterior surface of the lens optic, as is the case with the Lasagap lens.
