文摘

To investigate changes in corneal higher-order aberrations (HOAs) associated with the incision location in cataract surgery.

Setting

Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea.

Design

Observational case series.

Methods

Eyes were divided into 3 groups according to the different axes of incision location: superior, temporal, and nasal. Preoperative and 1-month postoperative corneal coma, trefoil, and spherical aberrations were compared.

Results

The study evaluated 119 eyes that had uneventful cataract surgery with a 2.2 mm limbal incision. The superior incision group showed significant changes in the vertical coma (amount of change: −0.119 μm ± 0.153 [SD]; P < .001) and vertical trefoil (amount of change: 0.185 ± 0.260 μm, P = .001). The nasal incision group showed a significant change in oblique trefoil (amount of change: 0.176 ± 0.207 μm; P < .001). The temporal incision group did not show significant changes in HOAs.

Conclusion

The superior incision in 2.2 mm phacoemulsification cataract surgery caused a change in the corneal vertical coma in a negative direction. Corneal trefoil changes were dependent on the incision location.
