Abstract
 
Purpose
 

To review, using topography, the incidence of pre-operative corneal abnormalities in patients undergoing cataract surgery, which may impact final visual results.

 
Methods
 

We conducted a chart review of 200 consecutive patients (400 eyes) that had preoperative corneal topographies (Nidek Magellan) from both eyes. Patients with a history of corneal refractive surgery were excluded. All patients underwent cataract surgery by one surgeon in Miami, FL.

 
Results
 

Results: ~25% of eyes scheduled for cataract surgery with no history of previous corneal surgery have abnormal Corneal Topography. 1.6% of eyes had topography consistent with FFK, 1.4% had topography consistent with Pellucid Marginal Degeneration. 3.0% had topography consistent with Keratoconus. 9.2% had topography that was borderline for FFKC, borderline for pellucid, or had superior steepening. 9.5% had irregular astigmatism or abnormal topography consistent with dry eye.

 
Conclusions
 

Pre-operative corneal topography is an important tool to evaluate patients prior to cataract surgery, to better understand the patient’s corneal shape, and to provide accurate post-operative expectations.
