Abstract: A posterior chamber implantable intraocular lens having haptics and additional attachment structure of a discontinuous or semi-discontinuous form associated with the haptics. The posterior chamber implantable intraocular lens can be implanted using conventional techniques if the posterior chamber is determined to be suitable and adequate for implantation using conventional techniques, or can be implanted utilizing the additional attachment structure if the posterior chamber is determined to be unsuitable and inadequate for implantation using conventional techniques.
