Clinical Evaluation of Aberration-Corrected Pure Diffractive MIOL in Toric and Nontoric Versions
Narrative Responses:
Purpose
Evaluation of an aberration corrected, pure diffractive multifocal IOL (MIOL) as a toric and non-toric version.
Methods
For cataract surgery we implanted a non-toric MIOL (ZMB00, AMO, USA) in patients with a corneal astigmatism of less than 1 [D] or a toric MIOL (ZMT--, AMO, USA) in patients with an astigmatism over 1 [D]. Surgical induced astigmatism was taken in account for the corneal astigmatism. Both models contain a near addition of +4.0 [D]. Pre-operative biometry was performed with the IOL-Master (V5.4, Carl Zeiss Meditech, Germany). Subjective refraction, corrected and uncorrected visual acuity, monocular and binocular (near in 30cm and distance [logMar]) as well as a binocular defocus curve were evaluated.
Results
One week after surgery monocular UDVA was 0.1 in both MIOL groups with an UNVA of 0.2 in the toric and 0.1 in the non-toric MIOL group [logMAR]. Patients with a toric MIOL and a non-toric MIOL in the other eye even reached a UNVA of -0.05.
Conclusion
The aberration corrected, pure diffractive multifocal IOL with and without astigmatism correction show good refractive results for near and distance visual acuity. The patient satisfaction is very high.
