Summary

To compare the effect of Limbal relaxing incisions (LRIs) plus spectacle correction versus spectacle correction alone on subjective and objective improvement in visual function for correcting post phacoemulsification high astigmatism .

Conditions

  • Astigmatism
  • Phacoemulsification

Interventions

PROCEDURE

Limbal relaxing incisions

A fixed depth diamond-guarded knife (Gemcision LRI 600 Microns Blade, Katalyst Surgical, chesterfield, MO, USA) will be used to create a paired circumferential corneal incision, following the limbal curvature, 1-1.5mm anterior to the limbus centered on the steep corneal meridian.
