Abstract:
We present a technique for the surgical correction of aphakia that allows intrascleral fixation of a posterior chamber intraocular lens (IOL) without sutures. The technique is useful in situations in which one haptic has to be fixated and capsule support is adequate for fixation of the second haptic. The haptic is externalized with a 25-gauge needle; no surgical instrumentation other than that needed for conventional cataract surgery is used. The technique is particularly appropriate for 3-piece IOLs with flexible haptics.
