Outcomes of IOL Scaffold Surgery
Narrative Responses:
Purpose
To evaluate the safety and 18 months outcome of Intraocular lens (IOL) Scaffold technique in eyes with soft to moderate nuclear remnants following intraoperative posterior capsule rupture (PCR).
Methods
Single centre, retrospective, interventional, non-comparative, consecutive case series. Analysis of medical records of 31 eyes of 31 patients who underwent IOL scaffold surgery was reviewed. A 3-piece, 6.0 mm optic, acrylic foldable IOL with modified C-loop haptic configuration was implanted. The preoperative and postoperative parameters evaluated were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), specular microscopy, gonioscopy, ultrabiomicroscopy (UBM), central macular thickness (CMT), intraocular pressure (IOP) and anterior and posterior segment inflammation. The final visual outcome at 18 months was evaluated.
Results
At 18 months follow-up, the mean postoperative UDVA and CDVA in Snellen’s decimal equivalent was 0.60±0.19 and 0.93±0.23 respectively. The IOL was placed in sulcus for 21 eyes, in the capsular bag for 4 eyes and glued intrascleral fixation of IOL was done in 6 eyes. The mean postoperative refractive error at the final examination was −0.3 diopter ± 0.09(SEM). The postoperative CDVA of 20/20 and 20/30 was achieved in 23 eyes and 8 eyes respectively. There was no correlation between preoperative specular count and percentage loss of cells. The mean CMT at 18 months was 181.68 ± 10.17 microns.
Conclusion
IOL scaffold provided an effective, relatively non-invasive means of emulsifying moderate to soft nuclear remnants in eyes with intraoperative PCR with a good visual outcome and a favorable complication rate.
