—I certainly concur that posterior intraocular lenses can be anchored transsclerally as described by Grehn and Sundmacher1 and Stark and colleagues2 in the July issue of the Archives. The illustrations indicated that the 10-0 prolene suture was tied around the haptics. Unfortunately, I have found that this knot may slip along the haptic while inserting the lens or adjusting the suture. The problem is eliminated if a one-piece PMMA lens with two holes in the distal haptic is used. A double-armed suture is simply threaded through the hole and both ends are tied on the sclera; this eliminates the risk of the knot untying or shifting position on the haptic.This small modification has greatly simplified the secondary insertion of implants, both in cataracts and penetrating keratoplasty.
