O_G....of course you are correct.
98% looks good odds UNLESS, you are in that 2%, then the odds don''t seem s exciting, especially as it is you one and only eye.
There may be other alternatives depending upon the divisibility of the patient, e.g spectacles, but by the looks of things this has been discussed with the Ophthalmic surgeon.
Again.....a difficult decision when one is discussing your one and only functioning eye, even with a 98% success rate.
