Mann-Whitney test for comparison between unilateral and bilateral refractive lens exchange (RLE).
^‡Visual symptoms are rated on a scale from 0 to 5 (0 = none; 1 = very mild; 2 = mild; 3 = moderate; 4 = severe; 5 = very severe).
Satisfaction is rated from 1 to 5 (1 = very dissatisfied; 2 = dissatisfied; 3 = neutral; 4 = satisfied; 5 = very satisfied).
