Abstract Details

Purpose:

Clinical evaluation of functional results and quality of vision after implantation of an aspheric, aberration free, monofocal intraocular lens (IOL).

Setting:

International Vision Correction Research Centre (IVCRC), Department of Ophthalmology, University of Heidelberg, Heidelberg, Germany

Methods:

So far, 10 eyes of 8 patients (median age: 63.5 years) with cataract have been enrolled in this ongoing prospective clinical study that was approved by the ethics committee. The MicroCryl MC 6125 AS aspheric IOL (HumanOptics/Dr.Schmidt Intraocularlinsen, Germany) was implanted after phacoemulsification. Follow-up examinations were performed one to four months after surgery including subjective refraction, ETDRS uncorrected (UDVA) and corrected distance visual acuity (CDVA), wavefront analysis, analysis of stray light (C-Quant), contrast sensitivity under different lighting conditions (F.A.C.T.) and a questionnaire.

Results:

One to four months after surgery, median UDVA was 0.10 logMAR (range: -0.06 to 0.76 logMAR). Median CDVA increased from 0.21 logMAR (range: 0.00 to 0.70 logMAR) preoperatively to -0.12 logMAR (range: -0.16 to 0.06 logMAR) postoperatively. Median difference between achieved vs. intended spherical equivalent was +0.29 D (range: -0.57 to +0.76 D). Median total HOA RMS (6 mm pupil size) was 1.98 µm (range: 1.14 to 4.81 µm). The median spherical aberrations were -0.47 µm (range: -0.73 to -0.36 µm). Analysis of stray light (C-Quant) revealed a median value of 1.27 log(s) (range: 1.10 to 1.55 log(s)).

Conclusions:

The MicroCryl aspheric IOL provides good and predictable functional results after surgery. Patients are not negatively influenced by stray light and show slightly negative spherical aberrations.
