VISUAL PERFORMANCE AND PATIENT SATISFACTION FOLLOWING IMPLANTATION OF A WAVEFRONT LINKING PRESBYOPIA CORRECTING INTRAOCULAR LENS

To report the visual and refractive outcomes and patient satisfaction following implantation of a wavefront linking presbyopia correcting intraocular lens (IOL) during cataract surgery.

Ayrshire Eye Clinic, Ayr, Scotland, UK

Prospective, interventional case series. 36 eyes of 22 patients underwent implantation of a wavefront linking IOL (ELON, Medicontur, Hungary) during cataract surgery by a single surgeon (SS). Monocular and binocular uncorrected visual acuities at distance (UDVA), intermediate (UIVA, 66 cms) and near (UNVA, 40 cms) and contrast sensitivity were collected at months 1, 3, 6 and 12. Defocus curves were measured at months 6 and 12. All subjects completed a VFQ – 25 questionnaires to assess their quality of vision.

There were no intraoperative complications. The mean UDVA were 0.19, 0.16, 0.15 and 0.10 (logMAR) at months 1,3,6,12 respectively. The mean UIVA were 0.24, 0.17, 0.28 and 0.25 at months 1,3,6,12 respectively. The mean UNVA were 0.31, 0.31, 0.37 and 0.28 at months 1,3,6,12 respectively. Monocular and binocular defocus curve at 12 months showed a visual acuity of 0.0 and minus 0.1 with a myopic defocus of 1.5 dioptres corresponding to 67 cms. VFQ -25 questionnaire analysis showed a high level of patient satisfaction and spectacle independence for distance, intermediate and most of near visual tasks.

 Implantation of a wavefront linking presbyopia correcting IOL provides stable refractive outcomes over time for distance, intermediate and near vision. Subjects also reported high levels of spectacle independence for distance and intermediate with low levels of visual disturbances.
