Evaluation of the higher order wavefront aberrations and the quality of vision after correction of aphakia by a retropupillary implantation of the Verisyze® iris‐claw intraocular lens

Abstract

Abstract Purpose To investigate the influence of the secondary implantation site of the Verisyse® iris‐claw intraocular lens (IOL) on high order aberrations (HOAs) using wavefront analysis in aphakic patients. Methods Twenty five aphakic patients (25 eyes) who had been left aphakic after complicated phacoemulsification, leaving no capsular support, but good iris support and clear unwounded cornea implantated with the aphakic Verisyse®(AMO) IOL either implanted retropupilarely or over the iris. Wavefront aberrations and contrast sensitivity were measured using the Imagine Eyes IRX3 SH aberrometer. Results Twelve patients were implanted in the anterior chamber versus thirteen, who had the IOL clipped behind the iris. Surgery was uneventful in all patients. No postoperative complication was observed in the two groups. Best corrected visual acuity was significantly higher and HOAs were significantly lower in the retropupilarely implanted group. Simulated contrast sensitivity results calculated from Point Spread Function measurements were significantly better in the retropupilarly implanted group. There was no significant difference regarding HOAs and vision quality between the retropupillary implanted group and the panel of control âtients implanted with standard monofocal IOL in the capsular bag. Conclusion In addition to being atraumatic, the Verisyse® IOL implanted behind the iris may restore vision in the absence of capsular support in a more physiological way than when fixated over the iris. The overall quality of vision is better when the Verisyse® is implanted behind the iris and comparable to values obtained with standard monofocal IOLs.
