OPINION
Introduction
Arlington Memorial Hospital Foundation, Inc. d/b/a Arlington Memorial Hospital (“Arlington Memorial”) appeals the jury verdict for Johnny W. Baird (“Baird”) in his medical malpractice suit. We are asked to consider whether the trial court erred by prohibiting a nursing expert to testify regarding the medical causation of Baird’s injuries and whether there was sufficient evidence of proximate cause to support submitting a negligence question to the jury. Because we hold the trial court did not err by limiting the nursing expert’s testimony, and the trial court erred by submitting the negligence issue to the jury because there was no evidence of proximate causation, we will reverse the judgment of the trial court and render judgment for Arlington Memorial.
Summary of Relevant Facts
On August 12, 1993, Dr. Nirmal Saran performed cataract removal surgery on Baird at Arlington Memorial. During the surgery, Baird sustained a corneal burn to his right eye. Baird sued the hospital for medical negligence on the theory that the surgeon used a previously used tip during Baird’s procedure, and the reuse of the tip caused his burn.
The procedure Baird underwent to remove his cataract is called phacoemulsifi-cation. Phacoemulsification involves the use of an instrument called a phaco tip, which is applied to the eye and breaks the cataract into minuscule particles that are removed by aspiration. The tip is attached to a phacoemulsification machine. It is undisputed that up until the time of Baird’s surgery Arlington Memorial routinely reused phaco tips. However, it is disputed whether the tip used in Baird’s surgery had actually been used previously.
The jury awarded Baird damages for Arlington Memorial’s negligence and gross negligence. This appeal followed.
Expert Testimony
In his sole cross-point, Baird argues the trial court abused its discretion by prohibiting his nursing expert, Mary Scardino, R.N., from testifying about whether, in her *921 opinion, the reuse of the needle caused the burn to Baird’s eye.
We review the exclusion of proffered expert testimony under an abuse of discretion standard.
See E.I. du Pont de Nemours and Co. v. Robinson,
Baird presented Scardino as a nursing expert. As a nursing expert, Scardino could testify about issues within her knowledge, skill, experience, and training.
See
Tex.R. Evid. 702. Baird properly questioned Scardino about the standard of reasonable nursing care in an effort to establish neglect on the part of the nurses that prepared the equipment prior to his surgery and the nurses that assisted during his surgery. However, Baird also attempted to solicit an opinion from Scardino to establish that the reuse of the tip caused Baird’s burn. Because Scardino was not shown to be qualified to medically diagnose thermal burns or to be an expert on the equipment used, the trial court properly prohibited Scardino from testifying about causation of Baird’s burn.
See Pace v. Sadler,
Insufficient Evidence
Arlington Memorial argues the trial court erred by submitting the negligence issue to the jury because there was no evidence of proximate cause. We agree.
In determining a “no-evidence” point, we are to consider all of the evidence in the light most favorable to the party in whose favor the judgment has been rendered, and to indulge every reasonable inference from the evidence in that party’s favor.
See Formosa Plastics Corp. v. Presidio Eng’rs & Contractors, Inc.,
A “no-evidence” point may only be sustained when the record discloses one of the following: (1) a complete absence of evidence of a vital fact; (2) the court is barred by rules of law or evidence from giving weight to the only evidence offered to prove a vital fact; (3) the evidence offered to prove a vital fact is no more than a mere scintilla of evidence; or (4) the evidence establishes conclusively the opposite of a vital fact.
See Merrell Dow Pharm.,
In a medical malpractice action, expert testimony is required to prove neg
*922
ligence or gross negligence unless the form or mode of treatment is a matter of common knowledge, or the matter is within the experience of a layperson.
See Hood v. Phillips,
To establish proximate cause, a plaintiff must prove: (1) cause-in-fact, i.e., that the defendant’s negligence was a substantial factor in bringing about the injury and without which no harm would have occurred; and (2) foreseeability, i.e., that the defendant should have anticipated the danger that resulted from his or her negligence.
See Bradley v. Rogers,
The requirement of establishing a causal connection between the negligence of one or more of the defendants and the plaintiffs injuries based upon a reasonable medical probability applies whether the opinion is expressed in testimony or in a medical record, as the need to avoid opinions based on speculation and conjecture is identical in both situations.
See Burroughs Wellcome Co.,
In this case, it is clear that a phacoemulsification and the instruments used in the procedure are not matters of common knowledge, or within the experience of laymen.
See Hood,
Baird was required to prove causation through the testimony of a medical expert.
See Bradley,
*923
When asked to assume the tip was reused, which was the premise for Baird’s entire cause of action, the doctor testified that he could not testify for certain as to whether the reuse of the tip caused the burn. At best, his opinion on causation was only a possibility. The mere possibility that an act of negligence
might
have been the proximate cause of damages from a medical viewpoint is not sufficient to support recovery.

Conclusion
When we sustain a “no-evidence” point, it is our duty to render judgment for the appellant because that is the judgment the trial court should have rendered.

TEX. R. APP. P. 43.3;

Notes
. Baird argues the jury could legitimately infer causation. Baird relies heavily on
Hernandez v. Altenberg,
. Because our holding is dispositive, we need not consider appellant’s remaining points.
