Effect of Glistening-Free Intraocular Lens on Intraocular Straylight
To compare intraocular straylight between glistening-free and conventional intraocular lenses in pseudophakic eyes.
Straylight values were measured prospectively in 21 eyes with glistening-free pseudophakic lenses (group A, model enVista, Bausch & Lomb, Inc.) and 79 eyes with conventional hydrophilic pseudophakic lenses (group B, model Akreos MI-60, Bausch & Lomb, Inc.). Best corrected visual acuity (BCVA) and straylight were measured preoperatively and 1 month and 2 months postoperatively using C-quant straylight meter (Oculus GmbH).
There were no statistically significant differences of BCVA preoperatively or 2 months postoperatively between the 2 groups (p > 0.05). BCVA and straylight significantly improved after the operation (p < 0.05). The mean straylight values were 1.43 ± 0.12 (log[s]) and 1.41 ± 0.16 (log[s]) for group A, and 1.33 ± 0.61 (log[s]) and 1.40 ± 0.82 (log[s]) for group B at postoperative 1 month and 2 months, respectively, with no statistical significance between the 2 groups (p > 0.05).
In terms of straylight, glistening-free intraocular lenses were not beneficial. Although straylight was not statistically significant, other correlations between glistening and visual function should be investigated.
