Purpose To investigate the significance of difference in straylight of cataract eyes with different morphologies, as a function of age and visual acuity. Methods A literature review to collect relevant papers on straylight, age, and visual acuity of three common cataract morphologies leads to including five eligible papers for the analysis. The effect of morphology was incorporated to categorize straylight dependency on the two variables. We also determined the amount of progression in a cataract group using a control group. Results The mean straylight was 1.22 log units ± 0.20 (SD) in nuclear (592 eyes), 1.26 log units ± 0.23 in cortical (776 eyes), and 1.48 log units ± 0.34 in posterior subcapsular (75 eyes) groups. The slope of straylight-age relationship was 0.009 (R 2 = 0.20) in nuclear, 0.012 (R 2 = 0.22) in cortical, and 0.014 (R 2 = 0.11) in posterior subcapsular groups. The slope of straylight-visual acuity relationship was 0.62 (R 2 = 0.25) in nuclear, 0.33 (R 2 = 0.13) in cortical, and 1.03 (R 2 = 0.34) in posterior subcapsular groups. Conclusion Considering morphology of cataract provides a better insight in assessing visual functions of cataract eyes, in posterior subcapsular cataract, particularly, in spite of notable elevated straylight, visual acuity might not manifest severe loss.

“…Glistenings as a source of increased straylight in the hydrophobic (control) group versus the hydrophilic (study) group is probably not the cause for the difference in straylight. One reason is because glistenings develop over time, and here the cut-off point was 3 months, and the other reason is because glistenings behave like a localized effect, comparable, for example, to defects caused by pitting of the IOL when performing a Nd-YAG-laser capsulotomy; the defects are not large enough to be detected by straylight measurements [20]. Since the outcomes of straylight in multifocal IOLs in the literature are mixed, this topic needs attention in future research.…”

Comparison of a hydrophilic and a hydrophobic apodized diffractive multifocal intraocular lens

et al. 2013

To compare outcomes between a new design apodized diffractive hydrophilic multifocal intraocular lens (IOL) (Seelens MF; study group), and a well-known apodized diffractive hydrophobic multifocal IOL (SN6AD1; control group). A comparative case series comparing refractive and visual outcomes at distance and near. Patient satisfaction with a validated questionnaire, dysphotopsia and straylight measurement scores were recorded at 3 months post-operatively. The study group comprised 48 eyes and the control group 37 eyes. At 3 months post-operatively the mean uncorrected distance visual acuity (UDVA) was not statistically significant different between the study group and the control group (0.02 ± 0.07 logMAR [SD] vs 0.04 ± 0.09 logMAR). Corrected distance visual acuity (CDVA) was statistically significantly better with the study lens (−0.04 ± 0.05 logMAR vs −0.01 ± 0.04 logMAR (p < 0.019). There was no clinical or statistical significant difference at the 40 cm distance (0.09 ± 0.12 logMAR vs 0.08 ± 0.09 logMAR). The study group had statistically significant better uncorrected near acuity at 50 and 60 cm distances (p < 0.03 and p < 0.007, respectively). In terms of satisfaction the lenses performed equally. Halos were seen less often with the study lens. Straylight, as a parameter for visual quality, was significantly less with the study lens. Conclusion: The Seelens MF performs equally as well as the well-known SN6AD1 for UCDA and CDVA. The Seelens MF performs better at intermediate distance, and seems to allow for better depth of focus, and increased visual quality. More study is needed to corroborate the last finding.

“…Glistenings usually do not impede visual function [16]. They are not thought to cause increased straylight, as the particles causing straylight need to be in excess of 10 nm in diameter, which the glistenings are not [17]. Other causes are vitreous turbidities, which were not the case in our patient, or corneal causes, like severe dryness.…”

Seven-year follow-up of unilateral multifocal pseudophakia in a child

et al. 2016

The purpose of the study was to report the long-term outcome of unilateral implantation of a multifocal intraocular lens (IOL) in a pediatric cataract. This study was carried out at Tertiary Academic Ophthalmology Department, AMC, Amsterdam. This is a case report study of a 7-year-old child with a unilateral irradiation cataract, in whom an apodized diffractive multifocal IOL (SN6D3, Alcon) was implanted at the time of cataract surgery. During the follow-up period, visual acuity was preserved at logMAR -0.1; the child did not develop amblyopia. Binocular single vision was established. Few glistenings were seen on the IOL. The non-operated eye developed more myopia during the follow-up period than the multifocally implanted eye. Straylight was increased to log(s) 1.83. Patient and parents satisfaction were high. In selected cases, unilateral implantation of apodized diffractive multifocal IOLs leads to good long-term results in terms of visual acuity and patient satisfaction. No untoward effects were seen, including few glistenings on the IOL. Straylight is increased, but subjectively not disturbing.
