Comparison Of Visual And Refractive Outcomes Of Scleral-Fixed Intraocular Lens Implantation In Same And Different Sessions After Intracapsular Cataract Extraction

To compare the effects of intraocular lens implantation with scleral fixation (SF-IOL) at the same versus different sessions on visual and refractive outcomes after intracapsular cataract extraction (ICCE).

University of Health Sciences, Beyoglu Eye Training and Research Hospital, Beyoglu, Istanbul, Turkey.

The records of patients who underwent SF-IOL with Z suture technique after ICCE for subluxated cataracts between 2017 and 2022 were retrospectively analyzed. Patients who underwent SF-IOL in the same session after ICCEwere referred to as Group 1 and patients who underwent SF-IOL in different sessions were referred to as Group 2. Demographic characteristics, follow-up times, preoperative and 6 months postoperative uncorrected and corrected distance visual acuity (UDVA- CDVA, LogMAR), spherical equivalent (SE), spherical, cylindrical, and absolute refractive error values were evaluated. Intraoperative and postoperative complications were recorded.

87 eyes of 87 patients (Group 1: 43 eyes, Group 2: 44 eyes) were included in the study. The mean age of the patients was 64.88 ± 14.12 years in Group 1 and 64.45 ± 15.85 years in Group 2 (p= 0.944). In both groups, CDVA values were higher in the postoperative period than in the preoperative period (p<0.001). The mean postoperative CDVA value in Group 2 was higher than in Group 1 (0.63, 0.83 logMAR, p= 0.003, respectively). There was no statistically significant difference between Group 1 and Group 2 in terms of postoperative SE, spherical, cylindrical, and absolute refractive error values (p>0.05 for all).

Although SF-IOL implantation in different sessions after ICCE surgery does not affect refractive outcomes, it may provide better visual results compared to the same session.
