EW CATARACT 61 February 2018 principle (induced spherical aberration rather than a diffractive optics design). The clinical performance seems prom- ising. An interesting aspect of the paper was the results of halometry, a tech- nique that uses a simulator to let pa- tients choose the size and shape of the halos they experience. This technique allows a comparison of different IOLs, although it is biased by the fact that individual patients may experience and describe the same halo differently.

Median UIVA at 80 cm was 0.01 logMAR (±0.17). Median differ- ence between achieved vs. intended spherical equivalent was –0.07 D (±0.21). Median reading acuity at 40 cm was 0.10 logMAR (median distance 40.30 cm, median speed 99 wpm, letter size 1.25 log units). Conclusion: The results with the Mini Well Ready aspheric EDOF IOL show promising postoperative results in terms of intermediate and distance visual acuity, patient satisfaction, and optical phenomena. Dr. Knorz: This paper looked at the performance of a new extended depth of focus IOL that uses a different optical best corrected visual acuity of 20/25 or better at 1 month postoperatively with no known retinal pathology. Ocular scatter index (OSI) data was collected at 1 month postoperative (HD Analyzer, Visiometrics, Costa Mesa, California). Results: The average OSI of patients with a monofocal lens was 0.8 vs. 1.35 of patients with the extend- ed depth of focus lens, which was found to be significant (p<0.039), however, both still within the low scatter range of the HD Analyzer. Conclusion: The OSI of monofocal vs. extended depth of focus lenses was found to be significant, though still within the low scatter range, which may impact postoperative satisfac- tion, visual quality, and surgical planning. Dr. Knorz: I liked this study because it did not look only at visual acuity but tried to correlate an objective measure to the visual symptoms reported by our patients. The authors observed a significant difference in light scatter between a monofocal and an extend- ed depth of focus IOL. This finding correlates with the subjective reports of our patients who observe "spider webs" or rings around lights and some halos or ghosting.

Cataract Methods: 35 eyes of 18 patients (me- dian age: 65 years) with cataract in a planned cohort of 30 patients have so far been enrolled. The Mini Well Ready EDOF IOL (SIFI Medtech, Italy) was implanted mostly bilater- ally. Follow-up examinations were performed between 2 and 4 months postoperatively including subjec- tive refraction, ETDRS uncorrected (UDVA) and corrected distance visual acuity (CDVA), reading acuity (Salzburg Reading Desk), contrast sensitivity (FACT), halometry, and an optical symptoms questionnaire. Results: Median UDVA was 0.13 logMAR (±0.13). Median CDVA increased from 0.43 logMAR (range: hand movements to 0.04 logMAR) preoperatively to 0.00 logMAR Watch a video of Dr. Knorz's presentation on EWAR
