Primary anterior chamber intraocular lens for the treatment of severe crystalline lens subluxation

Abstract

Subluxated cataractous and clear lenses are commonly treated by limbal or pars plana lensectomy followed by primary or secondary intraocular lens (IOL) implantation. Adjunctive capsular prosthetic devices have facilitated lens removal and IOL centration in these challenging cases but have also added complexity and potential complications to the procedure. Although crystalline lens extraction may be required to clear the visual axis in mild to moderate lens subluxations, we propose insertion of a primary anterior chamber IOL without lens extraction in severe subluxations when the eye is optically aphakic or can be made functionally aphakic following neodymium:YAG laser zonulysis. Two cases demonstrating this approach are presented.

Long term safety and efficacy of iris claw versus scleral fixated intraocular lens for management of ectopia lentis

“…Treatment of ectopia lentis is challenging. It varies from optical correction of refractive errors, 3 pharmacological mydriasis, 5 partially occlusive contact lenses, 6 LASER pupilloplasty using iris photocoagulation, and LASER zonulysis using Nd-YAG LASER 7 to surgical intervention. However, the optimal surgical technique is still under debate.…”
