Objective
A new minimal-invasive technique is presented for clear cornea implantation of one-piece acrylic posterior chamber lenses for transscleral suture fixation in aphakic eyes.
Methods
Implantation was performed in 19 aphakic eyes. Additional steps included ppV (n=2), silicone oil release (n=1), anterior vitrectomy (n=8), capsular bag removal (n=4), and iris suture (n=2). Based on the main steps of modern small-incision cataract surgery, implantation was performed through a self-sealing, 3.0-mm, temporal clear cornea incision using injector technique. After the transscleral suture pass a modified insertion of the lens into the cartridge with the haptics both extended was performed. The leading haptic was sutured before, the trailing haptic after secure implantation in the sulcus.
Results
In 18 eyes the lens centered well. No lens tilt was observed and the self-sealing tunnel incision remained water tight without any suture. The eyes were followed for up to 13 months and visual acuity improved in all eyes.
Conclusions
By using a self-sealing tunnel incision and injector technique, secure lens stability without tilt was achieved with significant visual improvement.
