Manasseh GSL, et al. - Researchers conducted this single-centre prospective double-masked randomized controlled trial to ascertain if the horizontal orientation of the intraocular lens optic-haptic junctions has an impact on the incidence of pseudophakic negative dysphotopsia. Two hundred twenty eyes of 201 candidates undergoing routine cataract surgery have been randomized to receive their intraocular lens either orientated with the optic-haptic junctions at 180° (‘horizontal’) or without manipulation following implantation (control). Data reported that the overall negative dysphotopsia incidence was 12.2%. Findings suggested that the simple intraoperative manoeuvre of rotating the intraocular lens to orientate the optic-haptic junctions at 180° can be a safe and efficient measure to lessen the risk of developing postoperative pseudophakic negative dysphotopsia in the first postoperative month. This is the first report showing the advantage of horizontal optic-haptic junction positioning to be sustained beyond the first postoperative day. No intraoperative adverse effects of intraocular lens rotation have been recorded.
