“…Cerviño et al also found that straylight values were not associated with the pupil size of the subject [19]. However, van Gaalen et al reported that straylight increased with increasing pupil size in pseudophakic eyes at one year after surgery [20]. Straylight values were significantly higher in dilated than those in natural pupils, which was contradictory to our study.…”

“…In van Gaalen's study, the presence of the anterior capsule rim in the pupillary area, not the pupil size, was considered as the main reason for the increase in straylight. The opacity of the anterior capsule rim may have increased the straylight significantly [20]. van Gaalen measured straylight using natural pupils and dilated pupils at one year after surgery.…”

Purpose. To investigate the intraocular straylight value after cataract surgery. Methods. In this study, 76 eyes from 62 patients were subdivided into three groups. A hydrophobic acrylic, a hydrophilic acrylic, and a PMMA IOL were respectively, implanted in 24 eyes, 28 eyes, and 24 eyes. Straylight was measured using C-Quant at 1 week and 1 month postoperatively in natural and dilated pupils. Results. The hydrophilic acrylic IOLs showed significantly lower straylight values than those of the hydrophobic acrylic IOLs in dilated pupils at 1 week and 1 month after surgery (P < 0.05). However, the straylight values of the hydrophilic acrylic IOLs were the lowest among the three IOL groups. No significant difference was observed in straylight between 1 week and 1 month postoperatively in each group with natural and dilated pupils (P > 0.05). Moreover, no significant difference was found in straylight between natural and dilated pupils in each group at 1 week and 1 month postoperatively (P > 0.05). Conclusions. Although the hydrophobic acrylic IOL induced more intraocular straylight, straylight differences among the 3 IOLs were minimal. Pupil size showed no effect on intraocular straylight; the intraocular straylight was stable 1 week after surgery.

“…The reason for the high straylight numbers in the study by Guo et al 34 might be that the straylight measurements were performed in a dark room with a subsequently large pupil diameter. Van der Meulen et al 24 and van Gaalen et al 35 separately found that intraocular scatter is closely related to pupil diameter in pseudophakic eyes. Their findings show that 1.0 mm of visible capsulorhexis remnant induces 0.52 log units of additional straylight.…”

PURPOSE:To assess normal values for straylight in the pseudophakic eye as a function of age and to develop a model to predict the improvement in straylight after lens extraction based on preoperative straylight levels.SETTING: Rotterdam Ophthalmic Institute, Rotterdam, the Netherlands. DESIGN:Review with retrospective cross-study analysis.METHODS: A literature review was performed to identify relevant papers on straylight and pseudophakia with no patient comorbidities. Sixteen papers met the eligibility criteria and were included in the analysis. The postoperative results were used to define the norm for straylight in pseudophakia. Straylight improvement after lens replacement was assessed by evaluation of preoperative and postoperative values. The age effect was incorporated to determine a model for straylight improvement. RESULTS:The mean postoperative straylight value derived from 16 studies (1869 eyes) was 1.21 log units G 0.21 (SD). Age dependence could be assessed from 13 studies (1533 eyes), resulting in the straylight age-norm curve in pseudophakic eyes as follows: Straylight value Z 0.0044 Â age C 0.89 with G 0.42 log units of 95% confidence interval. A strong correlation was observed between preoperative straylight and its improvement after lens extraction, yielding the following relationship: Straylight improvement Z 1.04 Â preoperative straylight value À 0.006 Â age À 0.84. CONCLUSION:A norm for straylight in the pseudophakic eye was developed that is considerably different from the previously published norm for the phakic eye. The new pseudophakic norm can be used clinically to predict the straylight value after lens replacement and as a reference criterion for clinical studies.

“…The pupils were undilated because dilation increases straylight. 25,26 The straylight source in the C-Quant Straylight Meter is an annulus with a 5 to 10 radius in the visual field that corresponds to the areas of guttae that we measured. 27 Unreliable straylight measurements were detected by the reliability parameters, and data with low reliability parameters were excluded.…”
