To evaluate the optical quality of the eye implanted with an Artisan / Verisize intraocular lens, after cataract surgery complicated by a lack of capsular support.
34 Consecutive patients (34 eyes) implanted with the Artisan / Verisize lens by a single between January 2004 and October 2005 were enrolled prospectively. They were randomized and the Artisan / Verisize lens was implanted either over (Group 1 / 16 eyes) or under the iris (Group 2 / 18 eyes). The wavefront aberration was calculated from images recorded with an Imagine Eyes IRX3 Hartmann–Shack aberrometer. This wavefront aberration was expressed as a Zernike polynomial expansion from the third up to the seventh order. Root mean square wavefront error was used as a parameter of optical quality. Point–spread function and modulation transfer function were also computed from the wavefront aberration and though objective measurements of contrast sensitivity were extrapolated.
The mean age of our patients was 85 +/– 11 years. No complications were encountered. An uncorrected visual acuity of 20/32 was observed 75% of patients. The mean postoperative root mean square values for Group 1 was significantly higher than in Group 2. The induction of trefoil observed in both groups ( Z 3,–3) is a result of the incision, whereas the increase of spherical aberration is due to the implant. Extrapolated contrast sensitivity is higher in group 2 than in group 1.
Preliminary data using the IRX3 Hartmann–Shack wavefront aberrometer tend to confort the idea that in addition to being atraumatic, the Artisan / Verisize intraocular lens implanted behind the iris may restore vision in the absence of capsular support in a more physiological way than when fixated over the iris.
