We wish to commend Cruikshanks et al1 on their excellent article, "Treatment Choice and Quality of Life in Patients With Choroidal Melanoma." In particular, it is encouraging to see their use of time trade-off utility analysis to evaluate the quality of life associated with a health state. In contrast to other quality of life instruments, utility analysis is theoretically more relevant because it attempts to encompass in a single measure all the possible aspects of quality of life.2 Utility assessment allows cost-effective analyses to incorporate the clinical effectiveness of interventional therapies with patient-based preferences and costs.3
