Three of the patients with EDOF implants elected to have the lens exchanged because of spiderweb effects; one patient with accommodating lenses elected for an exchange for the symptom of halos in both eyes; and one patient with one-piece acrylic lenses elected to have both eyes exchanged due to negative dysphotopsia. In conclusion, Dr. Cornell said that patients should be consented about the possibility 48 eyes), which included 6.3% with positive dysphotopsia and none with negative dysphotop- sia, glare, or halos. The silicone accommo- dating lens had 3.8% (13 of 341) of eyes with any aber- rations, which included 2.6% with glare, 0.6% with positive dysphotopsia, 0.6% with halos, and 0% with negative dyspho- topsia. Finally, in silicone three- piece IOLs, Dr. Cornell said none of the 57 eyes had any aberrations. Dr. Cornell added that lens exchanges were required spiderweb effects, 2.4% with positive dysphotopsia, 1.6% with halos, 0.8% with glare, and 0.8% with negative dys- photopsia. The second most common lens found to cause aberra- tions was the one-piece acrylic non-multifocal IOL, of which 7.8% (27 of 347) of eyes had any aberrations, which in- cluded 3.2% with negative dysphotopsia, 2.3% with pos- itive dysphotopsia, 1.2% with glare, and 1.2% with halos. The one-piece acrylic multifocal IOL came next with 6.3% of any aberrations (3 of by Ellen Stodola Editorial Co-Director I n a paper session on cata- ract surgery complications, Peter Cornell, MD, Beverly Hills, California, discussed dysphotopsias, glare, halo, and spiderweb optical effects from different IOLs. He first detailed the pur- pose of the study. IOLs can provide good results but can also have unwanted optical aberrations, he said, adding that the incidence, type of aberration, treatments, and comparison provide useful information when counseling patients about their options. His study was a retrospec- tive chart review of all eyes operated on by one surgeon over a 36-month period, which identified 921 eyes of 506 patients. All patients had preoperative explanations of possible optical aberrations, including glare, halo, spider- web effects, and positive and negative dysphotopsia. In the study, 58 eyes in 36 patients were identified with any of these symptoms noted at the 1-month visit, and those eyes were evaluated for the type of aberration and the frequency of lens exchange. A total of 58 of the 921 eyes (6.3%) and 36 of the 506 patients (7.1%) were identi- fied with optical aberrations 1 month after cataract surgery. Additionally, 22 patients had bilateral symptoms, and 14 pa- tients had unilateral symptoms. Twenty-seven of 307 (8.8%) women and 9 of 199 (4.5%) men had symptoms. The study also found that the most common lens causing aberrations was the extended depth of focus (EDOF) lens, of which 11.8% (15 of 127) of eyes had any aberrations, which included 6.3% with Dr. Cornell shares data on optical aberrations caused by different lens types in his study. The second chart breaks down the types of aberrations caused by each lens. Source: Peter Cornell, MD, screenshot from presentation
