Title : Comparative evaluation of single-incision ICL implantation with and without ophthalmic viscosurgical devices: Implications for postoperative IOP and visual outcomes
Abstract:
Objective: To evaluate the efficacy and safety of a single-incision intraocular lens (ICL) implantation technique with and without use of ophthalmic viscosurgical devices (OVDs), focusing on postoperative intraocular pressure (IOP) changes and visual outcomes.
Methods: This study analyzed IOP changes in patients undergoing ICL surgery, comparing the traditional OVD-assisted single-incision technique with a non-OVD variant. A total of 83 patients were included in each group. Postoperative IOP measurements were taken at multiple intervals, alongside assessments of uncorrected distance visual acuity (UDVA) to determine visual recovery outcomes.
Results: Both OVD and non-OVD groups demonstrated IOP levels within the normal range after surgery. However, a transient increase in IOP was observed at the 2-hour postoperative mark in 21 cases, with 10 cases (12.3%) in the non-OVD group and 11 cases (13.6%) in the OVD group. Notably, the non-OVD group exhibited fewer severe IOP elevations compared to the OVD group, suggesting a potential advantage in managing IOP postoperatively Fig1. Visual outcomes in terms of UDVA were excellent and comparable across both groups (P > 0.05), underscoring the non-OVD technique's ability to achieve similar visual success with reduced surgical complexity Fig2.
Conclusions: The non-OVD single-incision technique is a promising alternative to traditional OVD use in ICL surgery, offering reduced surgical time without compromising safety or visual outcomes. This approach may represent an efficient option for patients, with potential benefits in postoperative IOP control.
