Objective: Determine the Peroperatory difficulties and complications of cataract surgery by phacoemulsification.

Methodology: This is a descriptive prospective study from 02 January to 31 May 2023. Included were cataract surgery patients by phacoemulsification during the study period. Not included were patients operated on by other techniques and those who did not consent to participate. Recruitment was comprehensive. Our variables were epidemiological, clinical and therapeutic. Epi info version 7.4.0 was used for analysis.

Results: A total of 162 patients including 124 cataracts among which 24 or 19.35% were operated by phaco-emulsification. Average age 58.08 ± 19.75 years, sex ratio 1.4. Housewives were more represented 39.5%. Preoperative visual acuity ?1/10 dominates 66.7% in the right eye and 58.3% in the eye. Cataracts were mature and immature in 54.2% and 45.8%, respectively. The powers of the implants used ranged from + 19.0 D to + 25.0 D in 58.3% of cases. Ultrasound B showed a retina applied in 100%. Anesthesia was 100% inconsequential. The most encountered difficulties were related to the handling of the hand piece 8.3%. The most common intraoperative complications were implant expulsion from the anterior chamber 16.7% and posterior capsule rupture without vitreous output 12.5%.

Conclusion: Phacoemulsification is a reference technique for cataract surgery. The lack of control of the use of the device has given rise to some difficulties and intraoperative complications. Guinean ophthalmologists will have to make this technique the gold standard in cataract surgery.
