Objective:

Describe the effect of clear lens extraction on intraocular pressure in patients with primary angle closure glaucoma.

Methods:

A prospective longitudinal descriptive study was conducted in the Province of Pinar del Río from January 2013 to December 2019. The study included 54 eyes of 54 patients with primary angle closure glaucoma and clear lens treated with phacoaspiration. Statistical analysis was based on SPSS software.

Results:

Very significant differences were found (p< 0.001) between preoperative and postoperative intraocular pressure values. Significant differences were not observed in the number of drugs indicated (p= 0.317). Average intraocular pressure reduction percentage was 33.9 ± 4.3. By the end of the follow-up period, 68.5% displayed values of 18 mmHg or higher. Significant differences were found between the intraocular pressure control categories with respect to the stage of the disease, the existence or non-existence of previous peripheral synechiae, the mean preoperative intraocular pressure value, and the number of drugs (p= 0.006; p= 0.001; p= 0.001 and p= 0.045, respectively).

Conclusion:

Clear lens extraction reduces intraocular pressure in patients with primary angle closure glaucoma, a fact corroborated in the medium term, though most of the eyes treated do not achieve total control and the number of drugs remains unaltered.
