A Pilot Study to Investigate Scattering Light in Patients with Silicon IOLs Comparison of Sharp and Round Optic Edge Design
Walter S., Kollmann F., Lindner H., Behrens-Baumann W.
Purpose: Since one decade foldable IOLs containing different material (silicon, acrylic, hydrogel) are available. Several studies showed a postoperative visual acuity equal to rigid intraocular lenses. However the photopic visual acuity is only one aspect of the broad visual spectrum. Although many patients have an excellent visual acuity, some suffer from increased glare and reduced mesoptic visual acuity. The additional evaluation of visual acuity under mesoptic and glare conditions allows therefore additional functional testing which compared more to a real life condition. In this pilot study we investigated intraocular scattered light in relation to the edge design of the IOL (sharp vs. round edge) by means of contrast sensivity and glare.
