“…There is substantial evidence on the favourable short- and long-term outcomes of iris-claw IOLs in the treatment of IOL dislocation qualifying it as a valid alternative to scleral fixated or angle-supported IOLs. It is an efficient and safe surgical procedure 12 – 15 .…”

An 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.

Aim: This study investigated visual outcomes and factors that impact vision in children receiving secondary Intraocular Lens (IOL) implants. Methods: Children who had traumatic or congenital cataracts and underwent secondary lens implantation for aphakia at Drashti Netralaya between 2000 and 2019 were retrospectively examined. We included all the eyes with secondary implants for aphakia correction with placement either in the bag or sulcus or through scleral fixation. We obtained data from electronic medical records and analyzed using SPSS 22 through descriptive analysis, cross tabulation and t test. We evaluated visual outcomes among different patients. Results: Our cohort consisted of 84 eyes (mean age: 7.88 ± 6.07 years). Of the 84 eyes, 24 (28.6%) and 60 (71.4%) were female and male patients, respectively and 32 (38.1%) had traumatic cataract. We observed significant improvements in vision following lens implantation (p=0.000). Those with nontraumatic cataracts exhibited better outcomes that did the traumatic cataract group (p=0.004). Corneal opacity caused comorbidities in the traumatic group (14/52, 14.29%). Visual outcomes significantly improved in young patients and were not affected by other variables. Conclusion: Secondary lens implantation significantly improved vision in aphakic children. Young patients and those with nontraumatic cataracts demonstrated more favorable visual outcomes.
