XtraFocus pinhole device clears vision in pseudophakic patients

The XtraFocus pinhole device can help reduce glare and improve vision in pseudophakic patients with irregular corneal astigmatism or intragenic iris trauma, reports a recent study.

Drawing from electronic case records, researchers conducted a retrospective case series of 11 pseudophakic eyes of 11 patients (mean age 54 years) who had had XtraFocus implantation. Outcomes measured included visual acuity, patient satisfaction, and incident complications.

Over an average follow-up of 11.6 months, participants showed significant improvements in mean uncorrected distance visual acuity (UDVA; p<0.05). Such improvements were apparent and statistically significant starting from 1 month after operation and persisted until the 6- and 12-month visits. Mean spherical equivalents likewise changed significantly in the 12 months after surgery (p<0.05).

In particular, 10 patients showed initial UDVA improvement and achieved either stable or improved corrected distance visual acuity 1 month after operation. Vision remained stable throughout follow-up in eight patients (72.7 percent).

Four complications were recorded in the postoperative period, though only two were deemed directly related to the pinhole implant. In both cases, initial visual improvement was followed by the development of persistent glares or distressing floaters at 3- and 6-months, respectively. One patient opted for explantation 10 months after the initial surgery, leading to the complete resolution of glare. The other patient had also decided to undergo explantation and whose procedure was pending.
