Implantable Collamer Lens as an Alternative Supplementary Intraocular Lens to Correct Pseudophakic Refractive Error:...

To conduct a critical review of the peer-reviewed literature on the use of an implantable collamer lens (ICL) for the correction of pseudophakic ametropia.

A scoping review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using the National Library of Medicine (PubMed), EMBASE, and Web of Science as the primary source of information. Articles were selected based on predefined inclusion and exclusion criteria for this review, ultimately resulting in the selection of 17 articles for the current scoping review.

Data from 170 eyes of 147 patients were analyzed. Most of the reviewed studies exhibited short follow-up periods and had suboptimal designs, including case reports and case series with lack of clinical trials. However, most authors report that visual performance and refractive outcomes were significantly improved for all patients undergoing surgery, leading to enhanced postoperative uncorrected distance visual acuity with a very low complication rate.

The use of the ICL, both spherical and toric, as a supplementary intraocular lens for correcting pseudophakic ametropia represents a viable option for enhancing vision and improving patient satisfaction, with minimal associated complications. Nevertheless, further research with more robust study designs is necessary to validate these findings.
