Introduction: The choice of the surgical technique of cataract depends on the means, the patient and the abilities of the ophthalmologist. In our context of resource limited countries the Small Incision Cataract Surgery (SICS) is the rule and phacoemulsification an exception. The purpose of this survey was to compare two groups of patients operated with two different variants of SICS.

Methodology: Analytical cross-sectional study carried out in the Ophthalmology department of the Brazzaville University Hospital, between January and July 2019. Two groups (G1 and G2) of fourteen patients each suffering from cataracts had been operated. G1 and G2 were operated by the same surgeon, G1 with periorbulb anesthesia and self-sealing sclero-corneal tunnel, and G2 with topical anesthesia and self-sealing corneal tunnel. Two parameters had been compared: the existence of an orbital hematoma and the number of cotton stems used intraoperatively. The Student's test (t) with its confidence interval (95% CI) and the prevalence ratio (Rp) were used. The probability (p) was statistically significant for a value less than 0.05.

Results: Orbital hematoma 4G1 VS 0G2 (t = 2.1, 95% CI [2.4 - 8], Rp = 3.2, p < 0.05), Cotton stems 10G1 VS 3G2 (t = 3.2, 95% CI [3.8 - 7], Rp = 3.5, p < 0.05).

Conclusion: The variant with self-sealing corneal tunnel has three times less risk of bleeding. There is therefore less risk of contamination when the patient suffers from HIV infection or viral hepatitis.
