Purpose: To investigate the influence of intraocular lens (IOL) design and material on straylight in pseudophakes, and to investigate straylight in cataract patients and pseudophakes at different scatter angles.

Methods: Seventy-one eyes diagnosed for cataract were implanted with either a monofocal (spherical acrylic (N=16), aspheric acrylic (N=17), aspheric silicone (N=13)) or multifocal (silicone diffractive (N=13), acrylic diffractive (N=12)) IOL. Intraocular straylight was measured preoperatively and 1 week and 3 months postoperatively with the C-Quant (Oculus), which measures at an average straylight angle of 7 degrees. In 29 eyes, straylight was also measured with an adapted C-Quant, which measures at an average angle of 3.5 degrees.

Results: The average 3-month postoperative straylight values for the 3 monofocal groups were not statistically significantly different (log(s) between 1.26 and 1.37 for 7 degrees, log(s) between 1.41 and 1.45 for 3.5 degrees). For 7 degrees, the average value for the multifocal group (log(s)=1.32) was almost the same as for the monofocal group (log(s)=1.31). Also for 7 degrees, 80% of the patients had a lower straylight value at 3 months postoperatively compared to preoperatively. The 3.5 degree average results were higher than the 7 degree results postoperatively (pseudophakes), but not preoperatively (cataract patients).

Conclusions: For the patients implanted with monofocal IOLs, design and material did not influence the average straylight value postoperatively. There was also no difference found between the multifocal and monofocal groups. Cataract patients tend to have a different angular straylight dependence than pseudophakes.
