Abstract

Purpose: To ascertain the safety and outcomes of OVD vs OVD Free(OVDF) implantation(Under Irrigation) of Implantable Collamer Lens(ICL)

Methods: Based on OVD use during implantation, 230 patients undergoing ICL implantation for Myopia correction were randomly divided into 2 groups. Groups were compared postop in terms of Intra Ocular Pressure(IOP), Corneal Endothelial Cell Loss, Corrected Distance Visual Acuity(CDVA), Spherical Equivalent(SE), ICL Vault

Results: A rise in IOP>20 mmHg at 4 hours was noted in 66.0%&2.6% eyes in the OVD OVDF groups respectively(p < 0.001). There was no significant difference in the LogMAR CDVA or SE changes between the two groups(p <0.005). In the OVDF, mean endothelial cell loss was 4.6% & 3.2% at 3 months respectively in the OVDF and OVD groups(p = 0.187). No significant difference in the mean Postop vault between the 2 groups was noted(p<0.001) Conclusion: OVDF implantation of ICL is a safe & efficient method & can help avert Postop IOP spike
