Abstract
Purpose :
To compare post operative outcomes of scleral suturing of intraocular lenses (SSIOLs) at 2.5 or 3 mm posterior to the limbus to mimic either a sulcus implanted lenses or a lens placed within the bag, respectively.
Methods :
This is a single-center, retrospective case series analysis of data collected from an IRB approved surgical database of all retinal surgeries performed at Strong Hospital, University of Rochester, from 2020 to 2022. Eyes that underwent scleral fixated intraocular lens placement of enVista MX60E using Gore-Tex suture performed by three vitreoretinal surgeons were included. Outcome measures included postoperative changes in visual acuity (VA), ocular pain, (classified as requiring and not requiring adjustment in management, and no pain), elevated intraocular pressure (IOP >21), hypotony (IOP <5), retinal detachment (RD), and cystoid macular edema (CME). Statistical analysis was performed with a Chi squared test for association or Fisher’s exact test when appropriate performed using R studio.
Results :
Of 90 patients (90 eyes), 70 (78%) had SSIOL placed 3 mm from the limbus and 20 (22%) at 2.5 mm. Examination of surgeon-specific breakdown revealed that 3 surgeons performed 51 cases (19 and 42 receiving 2.5 and 3 mm SSIOL placement respectively), 17 cases (1 and 16), and 12 cases (0 and 12). Thirteen (65%) patients in the 2.5 mm group and 47 (67%) in the 3 mm group experienced at least one complication up to three months post-op. There were no statistically significant associations between SSIOL placement at 2.5 vs 3 mm from the limbus and frequency or type of post-op complications including CME, RD, hypotony, elevated IOP, or ocular pain up to three months post-op (Table 1). There were 46 patients who had VA data recorded at 2-3 months post-op. There was no significant difference between VA improvement or impairment for patients in the 2.5 or 3 mm groups from pre-op best corrected VA (Table 2); the remaining 4 patients, all in the 3 mm group, did not experience any worsening in VA.
Conclusions :
Placing an MX60E SSIOL at 2.5 or 3 mm from the limbus does not appear to affect post-op visual acuity and ocular complications.
