Lee HY, Choy YJ, Park JS - Korean J Ophthalmol (2011)

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.

Assessment of the facilitation of intraocular lens implantation. In group A, the ratings 'good', 'average', and 'poor' were assigned in 87% (27 / 31), 13% (4 / 31), and 0% (0 / 31) of cases, respectively, while those in group B were 74% (23 / 31), 26% (8 / 31), and 0% (0 / 31) (p = 0.202 according to the Mann-Whitney U-test).

Figure 3: Assessment of the facilitation of intraocular lens implantation. In group A, the ratings 'good', 'average', and 'poor' were assigned in 87% (27 / 31), 13% (4 / 31), and 0% (0 / 31) of cases, respectively, while those in group B were 74% (23 / 31), 26% (8 / 31), and 0% (0 / 31) (p = 0.202 according to the Mann-Whitney U-test).

Mentions: Three months post operation, there were four refractive myopic shifts (4 / 31) of more than -1.5 diopter in group A, while no refractive myopic shift (0 / 31) occurred in group B (p = 0.113). Six months postoperative, PCO occurred in three cases (3 / 31) in group A and in no case (0 / 31) in group B (p = 0.238) (Table 6). Fig. 3 shows the assessment of facilitation of IOL implantation. In group A, 'good', 'average', and 'poor' ratings were assigned to 87% (27 / 31), 13% (4 / 31), and 0% (0 / 31) of the eyes, respectively. In group B, these proportions were 74% (23 / 31), 26% (8 / 31), and 0% (0 / 31), respectively (p = 0.202). We measured the removal times for Amvisc Plus in group A and group B and calculated a mean OVD removal time of 50.42 ± 3.83 seconds in group A and that of 8.29 ± 4.40 seconds in group B (Fig. 4). Significantly less time was required for complete removal of Amvisc Plus in group B compared to that in group A (p ≤ 0.001).
