Background: Phacoemulsification is based on in situ fragmentation prior to extracapsular aspiration of the opacified lens through a small limbal or corneal incision. This low invasiveness allows surgery. Objective: to evaluate the importance of the AIT by the CMCPP on the strategy of opposition to pre-existing astigmatism. Methods: prospective study carried out from January 1st to August 31st, 2017 in the ophthalmology department of the Brazzaville University Hospital in 213 patients (240 eyes) presenting a cataract. The patient underwent cataract surgery using the CMCPP technique with incision on the axis of astigmatism, the astigmatism being evaluated as a positive cylinder. Results: The mean preoperative astigmatism was 1.49D, while the mean postoperative astigmatism was 1.83D. The group of patients with preoperative astigmatism greater than or equal to 1.5D was distinguished by an average of surgically induced astigmatism of -0.27 ± 1.62D. The group of patients with preoperative astigmatism less than 1.5 had a mean of surgically induced astigmatism of 0.88 ± 1.17D. In total, 63.6% of patients with preoperative astigmatism greater than 1.5D experienced a significant (p <0.05) decrease in postoperative astigmatism compared to only 23.3% of patients with preoperative astigmatism less than 1.5D. With respect to the variations in postoperative astigmatism according to the power of preoperative astigmatism, the reduction of astigmatism was found more in 77.8% of patients with inverse astigmatism (p = 0.03) compared to 11, 1% of patients with direct astigmatism. Conclusion: The neutralization of this strategy in the CMCPP is more evident with preoperative astigmatisms greater than 1.5D.
