Abstract

Purpose To evaluate the safety and efficacy after WIOL–CF (Wichterle Intraocular Lens- Continuous Focus) accommodative bioanalogic intraocular lens (IOL) implantation by means of subjective (visual acuity) and objective (wavefront analysis) measurements. Methods In this prospective case series, twenty – five patients (fifty eyes) with mean age: 65, 3 ± 8, 4 years (range from 53to 83 years) were included. All patients underwent routine cataract surgery and WIOL – CF accommodative IOL bilateral implantation. Preoperative evaluation included Uncorrected (UDVA) and corrected (CDVA) distance visual acuity (decimal scale) and uncorrected and corrected near visual acuity (Jaeger). Patients underwent topography, IOL Master (Carl Zeiss Meditec) and slit lamp examination preoperatively. During the follow-up visits, anterior segment Optical Coherence Tomography (AS-OCT, Visante) and wavefront analysis with the use of the WASCA (Carl Zeiss Meditec, Germany) wavefront analyzer and the i-Trace (Tracey Technologies, USA) wavefront analyzer were performed. Mean follow up was 11, 44 ± 2, 46 months (range from 9 to 17 months). Results Both monocular Uncorrected (UDVA) and Corrected (CDVA) distance visual acuity were statistically significantly (p΄&λτ0.05) improved from 0.31 ± 0.17 [range Counting Fingers (CF) to 0.7] to 0.74 ± 0.19 (range 0.2 to 1) (decimal scale) and from 0.61 ± 0.19 (range 0.2 to 1) to 0.82 ± 0.13 (0.4 to 1) respectively. No eye has lost lines of CDVA during the follow–up period while 88% of patients gained one or more lines of CDVA. Uncorrected intermediate and near visual acuity was J2 or better in 72% of our patients. No serious complications occurred intra or postoperatively. The evaluation of the mean values of root mean square (RMS) of higher order aberrations 3rd and 4th order at 1 year postoperatively revealed mean negative spherical aberration of -0.18 +/- 0.13 microns. Conclusions WIOL–CF accommodative bioanalogic IOL implantation provides satisfactory visual acuity for far, intermediate and near and the promising results remain stable throughout the follow–up period.
