Abstract Details


To share the pilot results and assess the potential visual benefits and consequently, vision quality of New Vision Implantable Collamer Lens (ICL V4c, STAAR Surgical Co) implantation to correct moderate to high myopia, as well as to compare them with the results of conventional ICL implantation.


Tbilisi State Medical University, Eye Clinic "Akhali Mzera" Tbilisi, Georgia


This prospective case series comprised 31 eyes (16 patients) that underwent ICL V4c implantation (3 spherical and 28 toric ICL cases) with myopic refractive errors of -6.5 to -16.0 diopters (D). The patients underwent ICL implantation and routine pre and postoperative examinations before and 1 week, 1 month, 3 months after the surgery. The control group included 46 eyes of 23 patients with conventional ICL surgery (among them 7 spherical and 39 toric ICL cases). The safety, efficacy, predictability, stability, and adverse events of the surgery were assessed.


No signs of pigment dispersion or hemorrhage as well as less inflammation in eyes that received the V4c surgery. As for the visual performance, there was no statistically significant difference between the main and control groups. No vision-threatening complications occurred during the observation period. The ICL group had lower aberration values of entire ocular and corneal HOAs in comparison of pre-op. HOAs changed for the entire ocular trefoil-y, spherical aberration and corneal trefoil-y. There were not statistically reliable differences between the main and control groups regarding HOA values but the patientsÂ’ satisfaction was higher due to several reasons: because of needless of additional surgical procedure before the surgery excluding very inconvenient complication/changes in some cases, low values of HOA (not statistically reliable), short rehabilitation period.


Implantation of ICLs is safe and effective and provides predictable and stable refractive results in the treatment of moderate to high myopia. The good control of IOP, eliminating the need for iridectomies, which can lead to significant changes in the aqueous dynamics after surgery, hypema, suggests its viability as a best surgical option for the treatment of such eyes. Moreover, it does not request the learning curve from the surgeon experienced in the implantation of previous model of ICL.
