To evaluate cataract incidence related with Implantable Collamer Lens (ICL) in posterior chamber.
Retrospective, observational and descriptive case series analysis of Implantable Collamer Lens implantation, myopic model V4 (ICMV4), (STAAR SURGICAL, Co), with previous Nd: Yag Laser iridectomy, between September 2001 and September 2008.
A total of 1, 507 eyes 833 patients with ICL implantation were included. Mean follow up of were 4.7 + 1.5 years (ranged 3 to 10 years). 20 eyes developed an anterior sub capsular cataract (1.33%), with a mean age of 40.0 + 4.9 years (ranged 29 to 47 years). Mean pre op spherical equivalent (SE) was -11.06 + 5.2 (ranged -3.50 to -20.00 D). The interval between lens implantation and cataract development was 4.0 + 2.0 years (ranged 6 months to 7.5 years). The mean vault before phacoemulsification was 102.0 + 73.8 microns (ranged 10 to 270 microns). The mean vault ICL lens dioptric powers between -3 .00 to -13. 50 D was 50 + 21.6 microns (ranged 10 to 80 microns), and the vault dioptric powers between -14.00 to -20.00 D, was 130.0 + 77.4 (ranged 60 to 270 microns). In 16 eyes, was implanted a multifocal diffractive intraocular lens, and in 4 eyes, a monofocal IOL.
The anterior sub capsular cataract incidence after ICL phakic lens implantation is low and its posterior treatment can be considered as standard procedure of refractive lensectomy.
