Abstract Details

Purpose:

To evaluate the long-term effectiveness and safety of the XtraFocus intraocular pinhole when it is implanted inside the capsular bag.

Setting:

Private practice. Cancado Trindade Eye Institute

Methods:

60 eyes of 58 patients who had the intraocular pinhole implanted in the capsular bag together with the primary IOL to treat irregular corneal astigmatism secondary to multiple causes were enrolled. Mean follow-up was 16 months (range 7 to 48). Patients were assessed in their scheduled follow-up visits. Uncorrected and best-corrected visual acuity were recorded at each visit. An infrared slit-lamp photography was captured and analyzed to verify the presence of interlenticular membrane formation.

Results:

Mean uncorrected and best-corrected visual acuity improved from LogMAR 1.34 ± 0.338 and 0.57 ± 0.145 preoperatively to 0.14 ± 0.012 (p<0.001) and 0.12 ± 0.008 (p=0.001) postoperatively respectively one year after surgery. Mild pinhole decentration was noted in 5 eyes (8.3%). Interlenticular opacification (ILO) was not noted in any patient.

Conclusions:

Implantation of the XtraFocus intraocular pinhole inside the capsular bag is safe. Improvement in both uncorrected and best-corrected visual acuity was significant and sustained overtime. ILO does not occur when this implant is positioned in the capsular bag together with a primary IOL.
