Purpose
To evaluate the efficacy and safety of in-the-bag implantation of the XtraFocus Intraocular Pinhole to treat irregular corneal astigmatism
Setting
Single center private practice
Methods
Retrospective analysis of 70 consecutive eyes that had the XtraFocus Pinhole implanted in the capsular bag to treat irregular corneal astigmatism. Mean followup is 24 months (12-60 months). Uncorrected and best-corrected visual acuity were recorded at each post-operative visit. An infrared slit-lamp photography was captured and analyzed to verify the presence of interlenticular membrane formation.
Results
There was a significant improvement of both uncorrected and best-corrected visual acuity after surgery varying from LogMAR 1.52 ± 0.209 and 0.41 ± 0.124 preoperatively to 0.121 ± 0.0101 (p<0.001) and 0.192 ± 0.005 (p<0.001) postoperatively respectively. No intraoperative complications were seen. Interlenticular opacification was not seen in any patient.
Conclusions
Implantation of the XtraFocus intraocular pinhole inside the capsular bag is a safe procedure. Longterm improvement in both uncorrected and best-corrected visual acuity was seen. Interlenticular opacification does not seem to be a significant complication with this device.
