ABSTRACT

Purpose: To evaluate the safety and the changes related to the implantation of a posterior chamber phakic intraocular lens (ICL) with ultrasound biomicroscopy.
Material and methods: Prospective and longitudinal study. Ten patients with high and moderate myopia were selected for refractive surgery and implantation of posterior chamber phakic intraocular lens. All patients were evaluated before surgery. After the procedure the patients were evaluated at the first and third month with ultrasound biomicroscopy to measure the depth of the anterior chamber, camerular angle, Vault, exact position of the lens and relation with other structures of the anterior chamber.
Results: Ten patients were included in the study, 4 females and 6 males with mean age of 28.5 years and range 20- 40 years. 13 eyes were included in the study, spherical ICL lens were implanted in 13 eyes, toric ICL lens in 4 eyes. The mean anterior chamber depth before surgery was 3.22 mm (range 3.8-2.96 mm), 2.41 mm (range 2.76–1.62 mm) at the first month and 2.42 mm (range 2.69–1.75 mm) at the third month. The mean camerular angle before surgery was 36.5° (range 45°-29°), 21.68° (29°-12.4°) at the first month and 22.1° (range 27°-14°) at the third month. Vault (the space from the posterior side of the ICL to the anterior capsule of the lens) mean was 566 µ (range 1065–208 µ) at the first month, and 564 µ (range 1051- 213 µ) at the third month. In 100% of the cases the ICL was located in the sulcus and in contact with the posterior side of the iris; no case had contact with the lens.
Conclusions: With the ultrasound biomicroscopy the safety of ICL has been demonstrated. It shows that the ICL is located in the sulcus and has no contact with the lens. The study also showed that the camerular angle was narrow. In all cases the ICL had contact with the posterior side of the iris.
