Comparison of clinical outcomes of implantable collamer lens implantation with and without use of an ophthalmic viscosurgical device.

PURPOSE

To compare the clinical efficacy of posterior chamber phakic implantable collamer lens (ICL) implantation with and without the use of an ophthalmic viscosurgical device (OVD).

SETTING

Onnuri Eye Hospital, Jeonju, Jeollabuk-do, South Korea.

DESIGN

Retrospective case series.

METHODS

Included were patients who underwent ICL implantation with the use of an OVD (OVD group) and patients who underwent ICL implantation without the use of an OVD (hydro group). Refractive error, endothelial cell density (ECD), intraocular pressure (IOP), vault, and adverse events were evaluated at 1 day, 1 week, 1 month, and 3 months postoperatively. The IOP and vault were checked 1 hour postoperatively, and the surgical time was recorded.

RESULTS

The OVD group comprised 54 eyes of 27 patients and the hydro group 49 eyes of 25 patients. There were no significant preoperative differences between the 2 groups. At 1 hour postoperatively, the IOP was significantly higher in the OVD group (P < .001); however, there was no significant difference in IOP between the 2 groups at other follow-up timepoints. Surgical time was significantly shorter for the hydro group (P = .032). There was no statistically significant difference in vault, ECD, or refractive error between the 2 groups during the 3-month follow-up period. No adverse events were observed.

CONCLUSIONS

ICL implantation without the use of an OVD was safe and effective. The advantages of this technique included a short surgical time, prevention of early postoperative IOP spikes, and cost savings due to OVD elimination.
