In my clinical practice, I counsel patients that in highly successful surgeries like cataract or refractive procedures, they are "low risk, but not no risk." The point being that although highly successful in the majority of cases, sometimes things go wrong. In ophthalmology, when the result is not as expected, the legal inquiry often begins with a deceptively simple question: Was this a recognized complication, or was it caused by substandard care? The answer usually depends on the entire course of treatment rather than on one isolated event.
In cataract surgery, disputed issues may include preoperative biometry, intraocular lens selection, posterior capsule rupture, retained lens material, a dropped nucleus, IOL decentration or dislocation, postoperative pressure elevation, corneal decompensation, retinal detachment, and infection called endophthalmitis. In LASIK or PRK surgery, the scrutiny may shift to candidacy, corneal topography, residual stromal thickness, refractive stability, dry eye, ectasia risk, glare, halos, loss of best-corrected vision, or the need for enhancement or other surgery.
A complication does not end the analysis
The occurrence of a known complication neither proves nor disproves negligence. The review should examine whether the patient was an appropriate candidate, whether relevant risks were identified, whether the procedure was performed reasonably, and whether the complication was recognized and managed in a timely way. A technically unavoidable event can be followed by inadequate management. By the same token, a poor outcome can result despite appropriate surgery and prompt intervention.
The operative report matters, but so do the preoperative examination, diagnostic testing, consent discussion, medication instructions, postoperative calls, and subsequent referral records. A clean operative note is little help in a claim involving poor candidate selection or delayed diagnosis of a postoperative problem.
Informed consent is more than a signature
A signed form is important evidence, but informed-consent disputes rarely turn on the signed form alone. The FDA's LASIK materials emphasize discussion of risks, benefits, alternatives, candidacy, and realistic expectations. For cataract surgery, the record may also need to show how lens options, refractive targets, and the limits of spectacle independence were addressed.
The most reliable opinion keeps distinct questions separate: Was the procedure medically appropriate? Was the technical care reasonable? Was a complication managed appropriately? Was the patient adequately informed under the applicable requirements? And, most importantly: what actually caused the claimed loss?
Postoperative timing often supplies the answer. Pain, reduced vision, inflammation, elevated pressure, flashes, floaters, or a sudden field defect may require different levels of urgency. The review should compare the patient's reported symptoms with the instructions given, the office's response, the examination that followed, and the point at which treatment or referral occurred. What happened after surgery in the office can be as important as what happened in the operating room.
