Presbyopia affects most people at the age of 40 years. It does not affect the life expectancy but diminish visual functions. After vision declines at the age of 40, it does not (hypothetically) decline more with advancing age. There is a new surgical procedure for this condition that restore vision to normal with no complication and costs INR. 100000. Life expectancy at the age of 40 in the general population is assumed to be 42 years and time trade off yields a utility value of 0.9 for presbyopia. Calculate the number of QALY with intervention and without intervention.
