The definition from Meriam Webster of eisegesis: " the interpretation of a text (as of the Bible) by reading into it one's own ideas "
Bringing one's own opinions into the scriptures (eisegesis), using a world view or preferred belief system to apply to the scriptures is not a hermeneutic practice. There is not any circumstance where that is acceptable.
There is a humorous post on "The Eisegisis 'Virus'" by Ken Ham at here that concludes that the leaders of churches today are infecting the message of the gospel of Christ with their own opinions and belief systems, and that the vaccine for it is exegesis.
Eisegesis [ < Greek eis- (into) + hègeisthai (to lead). (See 'exegesis'.)] Definition: A process where one leads into study by reading a text on the basis of pre-conceived ideas of its meanings. It is rare for someone to be called an 'eisegete', because eisegesis has a well-earned negative reputation.
Eisegesis is what's being done when someone interprets the Bible according to notions that were born outside of the Bible. In eisegesis, we read stuff into Scripture. For instance, the idea of the United States as a "Christian Nation" is the creation of egos who gloat over being powerful. It has no basis in history or fact, but more important, it has no basis in the Bible. Thus it arises from eisegesis. Yet some leading US politicians and pastors interpret the Bible through this notion.
To some extent, eisegesis is unavoidable. We don't come to the Bible with a blank slate. A lot of living and learning went into each of us. If we really bring our whole selves to the study of the Bible, all that stuff in us will and should have an impact on how we learn from the Bible. Here's where prayerful obedience and discipline come in, for the Spirit rewards hard work and harder prayer. The hard work of exegesis uncovers what the Bible is telling us, and our obedience sets aside the ideas we cherish so that we may take on the Bible's vision. The same living and learning that would have driven us to do an eisegesis of the text, instead becomes the raw material for re-visioning our lives and thoughts (through hermeneutics) in the light of what the Spirit reveals in Scripture (exegesis)."

Christ did not use scripture in a new application. He was fulfilling scripture, and explaining the original intent of the scriptures to those who applied it for their own desired belief system, much as many are doing today.
The accusation of using eisegesis comes out whenever someone opposes a commonly taught belief system, because the majority "interpretation" will not be challenged to review what they have always been taught. Therefore eisegesis becomes a matter of opinion over imposed opinions of the scriptures.
Matt. 27:46 was a direct quote of Psa. 22:1 which was the complete fulfillment of David's cry for help, and was prophetic of his savior's need. As the son of David, Christ fulfilled that prophesy on the cross.
The tempter's taunts of Christ in the wilderness was our example of how to resist the temptations that come upon us. The devil (tempter) had a short time (Rev. 12:12) to stop God's plan of salvation. He knew who Christ was, and he knew Christ's power. Turning those stones into bread was not the objective, but instead he attempted to turn the objective away from God's will toward fulfillment of selfish desires. Christ's response corrected the devil's desires. Christ did not introduce anything new, nor make application for His convenience.
I find the use of eisegesis everywhere today in most views and "interpretations" of the Bible. People argue that there are many different opinions of the Bible and that how one person reads it doesn't make it wrong for that person. To which I politely reply - "Hogwash".
The New Testament, or the new covenant is not NEW. It was promised beginning with God's promise of the seed to Eve in Gen. 3:15; to the promised seed of Abraham (Gen. 22:17; 26:4); the branch of David (Jer. 33:15) for the salvation of all who will call on Him.
Christ quoted the OT to those who heard Him in the first century AD, correcting their eisegesis. They had developed an incorrect belief system, namely that a Messiah would come to restore a physical, earthly kingdom to make the Jews rulers over all the earth. (Acts. 1:6) And, they still do not understand His word even today, as they are still trying to force that earthly rule upon Christ.
They do not understand that He rules from heaven, and coming back down to earth for a mere earthly kingdom as Satan lied and tempted Him with in Matt. 4:8-9 was never the objective.
So, eisegesis is not acceptable. A great many are practicing eisegesis today, using the scriptures to make application for their own expectations, and then turn around and accuse others of doing the same whenever their taught systems of belief are challenged.
Our attitude should always be "what does the word really say?". That is exegesis.
Excerpt from Dr. Richard J. Krejcir's article:
"This is using a presupposition or a pretext as in what we want so we can arrive at the meaning we want by ignoring the language, context, and culture in which it was used. Thus, "eisegesis" lends one "to lead in" or "read into the Scriptures," in contrast too, good biblical interpretation takes out what is really there whether we like it or not. Eisegesis means we input and plant the seeds of what we want it to say, gleaning just weeds later on, when with good exegesis, we harvest the good crops of what God is plainly saying."

"But have renounced the hidden things of dishonesty, not walking in craftiness, nor handling the word of God deceitfully; but by manifestation of the truth commending ourselves to every man's conscience in the sight of God." (KJV)
