Drops of lens nucleus/cortex particles into the vitreous cavity or dislocations of intraocular lenses (IOLs) are one of the serious complications of cataract surgery with an increasing relative frequency with the increase in the number of cataract surgeries. In addition, spontaneous and traumatic dislocations are other common case groups that should be treated. In this article, the vitreous dislocations of nucleus/cortex residues or IOL dislocations are discussed with different vitreoretinal surgical techniques.

AbstractAn Intraocular Lens (IOL) fixated on the iris either anteriorly, as a phakic IOL, or posteriorly, as an aphakic IOL, can influence pupil motility. In this interventional case series study, we evaluated pupil size under different levels of illumination (scotopic = 0.04 lx, low-mesopic = 0.4 lx and high-mesopic = 4 lx) for anterior iris-claw IOL fixation for correcting myopia or hyperopia (IFPH), retropupillary iris-claw IOL fixation to correct aphakia or as treatment for late in-the-bag IOL dislocation/subluxation (IFRP), and capsular-fixation IOL in-the-bag implantation (IB). Pupil size was measured preoperatively for the IFPH- and IB-group as well as 6 months after surgery for all groups. We analyzed a total of 70 eyes: 22 eyes of 11 patients with phakic IOLs, 22 eyes of 20 patients in the IFRP group and 26 eyes of 13 patients in the IB group. Both IFPH and IB showed a smaller postoperative scotopic pupil size, compared with the preoperative values. When compared to postoperative values of IB and IFPH, IFRP showed a significantly smaller postoperative scotopic pupil size (IFPH: 5.89 ± 0.83 mm, IFRP: 4.37 ± 0.83 mm, IB: 5.34 ± 0.98 mm, p < 0.001) while no differences were seen at high-mesopic lighting. Neither of the surgical techniques seems to impair the constriction of the pupil.

Scleral Fixated Intraocular Lens

Introduction: This study was conducted to report the refractive and visual outcome after Scleral Fixated Intraocular Lens (SFIOL) implantation in children with nontraumatic ectopia lentis. Methods: Retrospective review of the medical records of 25 eyes of 15 patients who underwent SFIOL implantation in children with non-traumatic ectopia lentis. Results: The mean best corrected visual acuity (BCVA) before SFIOL implantation was 1.07 ± 0.9 logMar units [median: 0.9, Interquartile range (ΙQR): 0.415 to 1.555] which improved to 0.41 ± 0.33 logMar units (median: 0.22, ΙQR: 0.180 to 1.555) at two months postoperative follow up. In phakic group, the mean spherical refraction preoperatively was -12.04 ± 7.82 DS (dioptre sphere) (IQR: +16 to -5.875) and postoperatively was +0.93 ± 2.67DS (IQR: -0.375 to +2). In aphakic group, the mean spherical refraction preoperatively was +12.22 ± 2.05 DS and postoperatively was +1.2 ± 1.9 DS. The mean total astigmatism preoperatively was -6.44 ± 4.95 DC (dioptre cylinder) (median: 6, IQR: -10.50 to +2) and postoperatively was -1.47 ± 0.98 DC (median: -1.5, IQR: -2 to - 0.625 ). The mean IOL induced astigmatism was -1.01 ± 0.95 DC (median -0.75, IQR: -1.33 to - 0.25). The spherical refractive equivalent was within 2 Diopter (D) of the target refraction calculated preoperatively in 20 eyes and in five eyes it was more than 2 D. Conclusion: SFIOL implantation is associated with good visual outcome with a significant improvement in the refractive error. However, a longer follow up is required to assess the change of refraction and the stability of the SFIOL.
