Abstract Details


To assess the visual outcomes, predictability, and safety of the Implantable Collamer Lens (ICL) (STAAR Surgical, Inc., Monrovia, CA) for the management of residual pseudophakic refractive error.


Instituto Universitario Fernandez-Vega


49 pseudophakic eyes with myopic, hyperopic, or toric ICLs were implanted were retrospectively analyzed. 29 eyes had been implanted with a monofocal IOL and 20 eyes had a multifocal IOL. All IOLs were implanted in the capsular bag. 6 out of 49 eyes had residual refractive error after phacoemulsification without corneal pathology or surgical alteration (virgin cornea group), 12 had LASIK or photorefractive keratectomy (PRK) (excimer laser group), 8 had radial keratotomy, 5 had intrastromal corneal ring segments (ICRS) implantation, 11 had penetrating keratoplasty, and 7 had deep anterior lamellar keratoplasty (DALK). UDVA, CDVA and manifest refraction were evaluated.


The efficacy/safety indices were 0.92/1.10, 0.98/1.13, 1.04/1.11, 0.90/1.13, 0.79/1.17, and 0.71/1.23 for the virgin cornea, excimer laser, radial keratotomy, ICRS, penetrating keratoplasty, and DALK groups, respectively. No eye lost one or more lines of CDVA. The virgin cornea, excimer laser, and radial keratotomy groups showed better predictability and accuracy ,with 96.2% spherical equivalent within ±1.00 diopters (D). The ICRS, penetrating keratoplasty, and DALK groups demonstrated approximately 50% spherical equivalent within ±1.00 D. There were no intraoperative or postoperative complications.


Good refractive outcomes and a strong safety record support the use of the ICL for the correction of residual refractive error in pseudophakic eyes with previous corneal surgery.
