Lasik operation. Please help me in this!

Sir, I went through a Lasik operation 5 years ago. Initially my power was minus 8.5 in right eye and minus 9 in left eye cylindrical. After operation it reduced to .75 minus in both eyes and after 1 year it increase to minus1 for both eyes & I start using glasses sometimes. But now after 5 years it seems my vision getting blurred after opening glasses and my local optician told me that my power is increasing in both the eyes. But during lasik operation my doctor told me your power will not increase after doing certain amount of tests. Two years ago I also went for pentacom test and results were fine in a time difference of 6 months. Now please help me in this regard as I don't want to wear power glasses. Shall I go for soft contact lenses? Please help
