We conducted a randomised prospective controlled study to determine the effects of a glucose glutathione bicarbonate solution (BSS Plus) and a citrate acetate bicarbonate solution (S-MA2) on the corneal endothelium in patients undergoing extracapsular cataract extraction with posterior chamber lens implantation. One eye of each patient was randomly assigned to receive BSS Plus, and the other eye to receive S-MA2. BSS Plus caused significantly less corneal swelling on the first postoperative day than did S-MA2. There was no difference between the two solutions in their effect on corneal thickness one week and one month postoperatively. Computer assisted morphometric analysis of wide-field specular microscopic photographs demonstrated minimal changes in endothelial morphological characteristics in the eyes irrigated with BSS Plus. By comparison S-MA2, caused a significant loss of endothelial cells and a marked reduction in the figure coefficient. These results indicated that BSS Plus has a clinical advantage over S-MA2 with respect to the corneal endothelium.

We studied the effects of intraocular irrigating solutions on the 30Hz flicker electroretinogram (ERG) during extracapsular cataract surgery in 45 eyes of 35 patients. The effects of two commercially available irrigating solutions. S-MA2 (Opeguard MA) and DE-057 (BSS Plus) were compared. After irrigation and aspiration (I/A) of the residual cortex with S-MA2, ERG amplitude increased to 111.2 +/- 5.8% of the pre-I/A amplitude. It significantly increased to 116.9 +/- 7.0% at the end of operation (p < 0.05) compared with before I/A. After I/A with DE-057, ERG amplitude increased to 109.5 +/- 5.3% of the pre-I/A amplitude. It significantly increased to 115.7 +/- 6.5% at the end of operation (p < 0.05) compared with before I/A. After I/A with S-MA2, ERG peak time was significantly prolonged to 103.9 +/- 0.8% of the pre-I/A peak time (p < 0.01). It was significantly shortened to 101.5 +/- 0.9% at the end of the operation (p < 0.001) compared with after I/A. After with DE-057, ERG peak time was significantly prolonged to 104.2 +/- 1.2% of the pre-I/A peak time (p < 0.01). It was significantly shortened to 101.3 +/- 1.22% at the end of the operation (p < 0.05). There were no statistical differences between changes of amplitude and peak time with S-MA2 and those with DE-057. We speculated that a drop in the retinal temperature during I/A in the anterior chamber and an increment of the photopic ERG amplitude during light adaptation with the operating microscope caused these ERG changes.
