To compare changes in corneal wavefront 4th order and total higher order aberrations (HOAs) after cataract surgery in patients with and without limbal relaxing incisions (LRI).
Patients undergoing cataract surgery without concomitant corneal disease were prospectively identified. Patients with greater than 1 diopter of astigmatism were enrolled in the LRI group using a standardized nomogram. Topography data from the pre-operative visit and 1 month post-operative visit were used to generate corneal 4th order and total HOAs.
15 eyes were identified. 4th order aberrations in patients with LRI increased from 0.079 to 0.105 (P=.0016). 4th order aberrations in patients without LRI did not change significantly after cataract surgery (pre-op: 0.0741, 1 month: 0.0767, P=.7546). Total corneal HOAs in patients with LRI increased from 0.1749 pre-op to 0.2730 at 1 month, which was statistically significant (P=.0087). Total corneal HOAs in patients without LRI again were not found to change significantly following surgery ( pre-op: 0.2056, 1 month : 0.2043, P=.9577).
