1. Researchers found that straylight value of 1.56 log(s) is a crucial threshold for recommending surgery.
2. IOL exchange led to significant improvements in contrast sensitivity, visual acuity, and patient-reported outcomes.
3. Patients who declined surgery showed no significant changes in straylight or visual symptoms.
4. The investigators concluded that straylight and contrast sensitivity measurements better capture visual impairment due to calcification compared to visual acuity alone.
