Abstract

Purpose: To evaluate the effectiveness of limbal relaxing incision (LRI) during phacoemulsification for correcting pre-existing corneal astigmatism.Methods: The study included 21 eyes of 21 patients undergoing phacoemulsification combined with LRI and 36 eyes of 36 patients undergoing phacoemulsification without LRI as controls. LRI was created according to a nomorgram based on preoperative astigmatism as determined by topography. Jaffe vector analysis was used for evaluation of changes in astigmatism.Results: Mean corneal astigmatism was 2.82±1.07 diopter (D) preoperatively which decreased to 1.68±1.03 D 12 weeks postoperatively in the LRI group. Corresponding figures were 0.66±0.27 D and 0.62±0.22 D in controls respectively. Mean arithmetic reduction in keratometric astigmatism was 1.19±1.04 D and mean vector change in cylinder was 2.37±1.36 D in the LRI group. Thirteen cases (61.9%) of under-correction and two cases (9.5%) of over-correction occurred in the LRI group.Conclusion: Limbal relaxing incision is effective in reducing pre-existing corneal astigmatism during cataract surgery; however a modified monogram is needed.
