Implantable Collamer Lens (ICL) Surgery segmentation by type classifies the devices according to optical design and structural features, principally V4b, V4c, and toric variants. The V4b model represents the legacy platform lacking a central aperture; it relies on peripheral iridotomy to prevent postoperative pupillary block, a requirement that adds procedural steps and potential complications. The V4c generation introduced a 360‑micron central hole, eliminating the need for pre‑operative iridotomy and improving aqueous humor flow, which has accelerated its market share growth among surgeons prioritizing safety and operative efficiency. Toric ICLs incorporate cylindrical power to correct astigmatism concurrently with spherical refractive error, expanding the addressable patient pool and contributing to higher average procedure revenue. Within the toric category, sub‑variants differentiate by axis‑alignment technology—manual versus automated positioning systems—affecting surgical time and postoperative predictability. The relative pricing hierarchy, with V4c and toric models commanding premium rates, directly influences overall market size, as adoption trends reflect both clinical benefit and cost‑benefit considerations across ophthalmic practices.
