Purpose:The purpose of this study is to evaluate and to compare the results of primary and secondary scleral-fixated posterior chamber intraocular lens (PCIOL) implantations in adult patients.Materials and Methods:A retrospective analysis of scleral-fixated PCIOLs-implanted during (primary group) or after (secondary group) cataract surgery was performed. The median follow-up time of 96 patients was 6 months (minimum: 6; maximum: 35 months). Outcome measures were indications, corrected distance visual acuity (CDVA), change in visual acuity and complications.Results:A total of 37 patients (38.5%) had primary implantations and 59 (61.5%) had secondary implantations. Penetrating keratoplasty was combined with secondary implantation in 13 cases. The median post-operative CDVA was 0.5 in decimal notation in both groups (P = 0.576). The CDVA improved by at least one Snellen line or remained unchanged in 35 eyes (94.6%) in the primary group and in 52 eyes (88.1%) in the secondary group (P = 0.263). Eyes with CDVA of 0.5 or higher were 62.2% (n = 23) in the primary group and 67.8% (n = 40) in the secondary group post-operatively (P = 0.066). The difference in early and late complications were not statistically significant between groups (P = 0.637, P = 0.154, respectively). Regarding late complications, 30 eyes (81%) in the primary group and 40 eyes (67.9%) in the secondary group had no complications (P = 0.154).Conclusion:Both primary and secondary scleral-fixated PCIOL implantations can provide favorable visual outcomes with lower complication rates. An important consideration is the appropriate timing for scleral fixation, taking into account the patient's characteristics and the course of the operation.

The RNFL thickness in CRF without DM, which was measured by OCT-3, was found to be significantly decreased. The presence of CRF can be a source of false positive results and lead to overestimation of glaucomatous optic neuropathy.

Vitreomacular adhesion seems to have an adverse effect on the visual prognosis of anti-vascular endothelial growth factor treatment for age-related macular degeneration.

The long-term outcomes of phacoemulsification with intraocular lens implantation in patients with uveitic cataract were satisfactory with excellent visual acuity and relatively low complication rates.

In both pediatric and adult patients, SFIOL implantation ends with favorable outcomes over the short term.
