Abstract Details


To evaluate the visual outcomes and complications after implantation of V4c ICL(with centraflow) and V4 for correction of high myopic astigmatism.


Eye research centre, Rassoul Akram Hospital, Iran University of Medical Sciences and Iranian Eye Clinic, Tehran, IRAN.


: V4c and V4 ICL implantation done for correction of high myopic astigmatism with at least 1 year follow up. The outcome measures that were evaluated included pre and postoperative UDVA, CDVA, endothelial cell count (ECC) lens opacification, IOP and lens rotation.


46 eyes underwent V4c ICL implantation and 40 eyes had implantation of V4 ICL with PI. Mean preoperative SE was -8.65 and -8.51D in the V4c and V4 groups which reduced to postoperative values of 16 and 33 D respectively. Mean preoperative cylinder was -1.38 and -1.65 D that respectively reduced to 51 and -0.46 D. At 1 year, mean ECC loss was 2.4% and 3.1%. 1eye of V4c and 3 eyes of V4 groups required rerotation surgery. Safety and efficacy indices were same and Lens was clear in both groups.


Both V4c and V4 Visian ICL implantations are comparable in terms of visual outcome and safety profile for correction of high myopic astigmatism.
