Lente intraocular plegable Hydroview® (H60M): resultados funcionales y hallazgos postoperatorios

Resum

Purpose: To study visual quality and postoperative complications after phacoemulsification and hydrogel (Hydroview®, H60M) IOL implantation, at one year postoperatively. Methods: Prospective study of 60 patients. After capsulorhexis and phacoemulsification, patients received a foldable hydrogel lens or a PMMA IOL. Postoperative examinations were made on 7, 30, 60, 180 and 360 th day. We measured distance visual acuity, contrast sensitivity, keratometry, anterior capsule fibrosis and the presence of other postoperative complications. Results: Small incision and foldable IOL provided faster visual rehabilitation, however visual acuity was better with PMMA lens (F=4.33, p<0.5) at 12 months after surgery. Contrast sensitivity at high spatial frequencies was significantly better in PMMA lens group. Anterior capsule fibrosis is more important in hydrogel IOL group (χ2 = 10.87, gl = 3, p<0.025). Other complications in the two groups were few and comparable. Conclusions: Hydrogel IOL provided good visual results and rapid visual recovery. However visual results are unstable. Anterior capsule fibrosis and on anterior intraocular lens surface fibrosis are common complications with hydrogel lens.
