Copeland radial pan-chamber lens for anterior and posterior chamber implantation

In order for a lens to achieve ecumenical use, it must be adapted for intracapsular, extracapsular, as well as secondary and exchange implantation techniques. In anterior chamber placement it must overcome the objections to early anterior chamber lenses, namely, pain, tenderness to touch, "UGH" syndrome, malrotation, "oil-canning" effect, and iris chafing. Ease of insertion and one uniform sizing which avoids lens inventories are now available. Reversing the lens into the posterior chamber after extracapsular extraction must also allow for each of insertion and avoidance of sunset syndrome and pupil trap. The Copeland radial pan-chamber lens has been used extensively by the author who reports on 103 eyes after posterior chamber placement and 43 eyes in which anterior chamber placement has been undertaken following uneventful extracapsular (phacoemulsification) lens extraction.
