Femtosecond laser-assisted cataract surgery: an incision efficacy review
Main Article Content
Abstract
Purpose: This study reviewed the scientific literature on corneal incisions in femtosecond laser-assisted cataract surgeries compared to keratome incisions in conventional phacoemulsification.
Conclusion: There are differences in the results of the studies. Automated incisions are more advantageous in the structure of the cut (reproducible tunnel architecture) and healing time of incisions (epithelial and endothelial gap, endothelial misalignment, Descemet membrane detachment and corneal thickening) compared to manual incisions, in addition to astigmatism correction <1.0 diopter with arcuate incisions. The induction of astigmatism and corneal aberrations is similar between the techniques. Incisions with an angle of entry of 110º in the cornea, triplanar shape, and width of <2.65 mm with the femtosecond laser platforms have presented the best results.
