Corneal topography useful for detecting asymmetry, assessing image quality

WASHINGTON — Topography is a valuable tool to detect corneal irregularity and asymmetry, a speaker said during Refractive Day at the American Society of Cataract and Refractive Surgery meeting.
“Corneal topography aids in planning and guiding treatment with high predictability and helps us plan for cataract surgery candidates,” Marcony R. Santhiago, MD, PhD, said.
It is important to take a detailed look at the topography, particularly near the visual axis.
“If you have any asymmetry, which is the hallmark of any ectatic disease, you can look at the topography to find that,” he said.
Corneal topography is important to assess image quality in cataract surgery patients, Santhiago said, particularly when deciding whether a patient is eligible for a special type of IOL. This may include patients who have had previous hyperopic treatment or patients with astigmatism.
“For a spherical aberration, if that patient has negative values, they may be a good candidate for a spheric IOL and not an aspheric IOL,” he said.
