Abstract
Purpose: :
To evaluate cataract incidence related with Implantable Collamer Lens (ICL) in posterior chamber.
Methods: :
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.
Results: :
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.
Conclusions: :
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.
