[Evaluation of the dependence between the lens thickness and intraocular pressure after cataract extraction in patient with glaucoma].
OBJECTIVE
The main purpose of the study is the evaluation of the dependence between lens thickness in eyes with cataract and glaucoma and the intraocular pressure after cataract extraction with posterior chamber lens implantation.


METHODS
138 eyes with cataract and glaucoma were examined. Patients were divided into three groups according to the type of glaucoma: I open angle glaucoma II closed angle glaucoma III glaucoma with pseudoexfoliation syndrome All patients received preoperatively drugs reducing intraocular hypertension. The intraocular pressure was measured on operation day and on the first and fifth day after. The subsequent measurements were carried out one month, 3 months and nine months postoperatively. Lens thickness measurement was conducted with ultrasonography one day before operation.


RESULTS
The dependence between lens thickness and intraocular pressure normalization (p < 0.005) has been found on the basis of statistical research with t-Student test in the closed angle glaucoma group with the greatest preoperative lens thickness.


CONCLUSIONS
The statistically proven dependence between preoperative lens thickness and postoperative intraocular pressure reduction in patients with the closed angle glaucoma, has been found on the basis of conducted research.
