Posterior Chamber Toric Implantable Collamer Lenses – Literature Review

Posterior Chamber Phakic Toric Implantable Collamer Lenses have become increasingly used to correct refractive error associated with astigmatism. These devices are claimed to provide high efficacy in terms of refractive correction. This book chapter is an updated review on the safety and effectiveness and potential complications of the toric implantable collamer lens (Toric ICL) published in peer-review literature. Toric implantable collamer lens (Toric ICL) from Staar Surgical Inc., Monrovia, CA, is a posterior chamber phakic intraocular lens that has been demonstrated to provide safe, effective, predictable and stable visual and refractive outcomes among various refractive ranges of ammetropia1-4. The present review will focus on the use of Toric ICL in the treatment of myopic astigmatism in normal eyes as well as in eyes with keratoconus, pellucid marginal degeneration, after keratoplasty, and also as a secondary piggyback lens.
