Taylor did not bat in the second innings of the series-opening test in Christchurch after having an preliminary eye test on the first day and was a doubt for the second match at Seddon Park in Hamilton starting on Friday.
After the Black Caps wrapped up victory on Sunday, coach Mike Hesson said the 32-year-old former skipper had experienced a problem with vision out of the eye for about a year and a test showed it may have deteriorated "quicker" than hoped.
However, a second eye examination in Hamilton returned a more positive prognosis.
"Ross has a pterygium on his left eye, which is gradually getting bigger. Both the specialists he's seen in recent days have advised Ross still has 20/20 vision and Ross himself feels confident he is ready to play," team physiotherapist Tommy Simsek said.
"Ross will still need to undergo a medical procedure on his eye to remove the pterygium before it gets any larger.
"He'll have surgery following the test which rule him out of cricket for approximately four to six weeks."
