"My right eye was so dominant. [The deterioration] is just a gradual thing as you get older, that's what I put it down to. After the medical procedure, my eyes have improved from a couple of months ago - I'm very happy [with the operation].
"As a batsman, all those one per centers are important, because they can be the difference between seeing the ball well or nicking off."
The 32-year-old's conversations with selectors Mike Hesson and Gavin Larsen had been kept to a minimum.
"He [Hesson] just said I'm not in the team, so he's hasn't really said anything else.
"I asked the question, when I got dropped for Bangladesh. You've got to respect their decision, and for this match [the solitary T20 against South Africa on Friday] I heard I wasn't selected and didn't ask any more questions.
"The selectors are there to do a job and my job's to play good cricket when selected. I enjoy playing all formats and hope to score some runs on Sunday [in the first ODI at Hamilton]."
The selectors' have picked sides that have won New Zealand each of the 12 home matches across all formats this summer, including three T20s against Bangladesh.
Taylor expected more clarity on his T20 future at the end of the season.
"I'm not a person to come out and throw my hands around. I just want to play for my country, but if you're not selected, it's your livelihood, so you've got to go somewhere else, I guess."
Taylor said he was looking to play international cricket until the 2019 World Cup and possibly beyond.
