المستخلص Intraocular lens implantation is the standard procedure for correction of aphakia especially in unilateral aphakia or bilateral aphakia with intolerance to spectacles and contact lenses. The endocapsular placement of IOL is undoubtedly anatomically preferable following successful cataract extraction. However the presence of an unstable capsule-zonule complex or its absence, e.g.: trauma, complicated cataract surgery or congenital zonular weakness, prevents the endocapsular fixation of the IOL. A similar predicament arises if an eye has been left aphakic or the IOL-capsule complex has subluxated, which usually occurs secondary to pseudoexfoliation. In such a situation, the surgeon has four options: (1) to leave the eye aphakic; (2) to implant an ACIOL ; (3) to fixate a PCIOL in the iris; or (4) to fixate a PCIOL in the sclera. |
