Bottom Line: Surgical results were compared between the two groups.The values of endothelial cell density, central corneal thickness, anterior chamber inflammation, myopic shift, and posterior capsule opacification were not significantly different between the two groups.Compared with the use of OVD for IOL implantation, use of BSS during IOL implantation resulted in reductions in postoperative IOP spike and OVD removal time.

ABSTRACT

Purpose: To compare surgical results between conventional intraocular lens (IOL) implantation using an ophthalmic viscosurgical device (OVD) and IOL implantation using a balanced salt solution (BSS) after irrigation/aspiration (I/A) of the lens cortex.

Methods: A randomized prospective study was conducted on 62 patients who underwent cataract surgery. Following completion of conventional I/A of the lens cortex, we divided patients into two groups according to whether or not BSS was used. In group A (n = 31), the anterior chamber and the capsular bag were completely filled with an OVD before IOL implantation. On the other hand, in group B (n = 31), BSS was irrigated into the anterior chamber through a previous side port during IOL implantation. Surgical results were compared between the two groups.

Results: In both groups, IOP peaked six hours after surgery. The occurrence of an IOP spike by postoperative day one was observed in six cases (6 / 31) in group A and in no cases (0 / 31) in group B, a difference that was statistically significant (p = 0.024). The values of endothelial cell density, central corneal thickness, anterior chamber inflammation, myopic shift, and posterior capsule opacification were not significantly different between the two groups.

Conclusions: Compared with the use of OVD for IOL implantation, use of BSS during IOL implantation resulted in reductions in postoperative IOP spike and OVD removal time.

The change in mean intraocular pressure (IOP) over time. In both groups, IOP peaked six hours after surgery, with a mean of 21.43 ± 6.41 mmHg in group A and 17.41 ± 5.12 mmHg in group B. The difference between the two groups was significant (p = 0.034). IOP then showed a gradual decrease to preoperative levels by seven days postoperative.

Mentions: Fig. 2 shows the change in IOP over time. In both groups, IOP peaked six hours after surgery, with a mean IOP of 21.43 ± 6.41 mmHg in group A and 17.41 ± 5.12 mmHg in group B. The difference was significant (p = 0.034, according to the Mann-Whitney U-test). The IOP then gradually decreased to preoperative levels by seven days postoperative. Six IOP spikes were observed in group A (6 / 31) one day after surgery, although no cases (0 / 31) were observed in group B, another significant difference (p = 0.024) (Table 2).
