Surgeon advises preoperative topography for all patients undergoing cataract surgery
AMSTERDAM — Corneal topography results were abnormal in 25% of patients with no prior history of corneal refractive surgery, according to a presenter.
In a study of both eyes of 200 consecutive patients, William B. Trattler, MD, and colleagues masked and evaluated preoperative topography results of patients scheduled for cataract surgery. All topography was done with the Magellan corneal topographer (Nidek) and all surgeries were performed by the same surgeon.

“Surprisingly, 69.3% were graded as normal and 30.6% were graded as abnormal,” Trattler said.
After filtering out patients who had undergone prior corneal refractive surgery, 75.3% were normal and 24.7% were not normal.
“This is a simple, straightforward study that hopefully emphasizes the importance of performing a preoperative corneal topography in every single patient prior to cataract surgery to better understand the patient’s corneal shape and to advise the patient what to expect,” Trattler said at the European Society of Cataract and Refractive Surgeons meeting.
