HERNANDEZ SILVA, Juan Raúl et al. Experience gained with the use of intraocular lens RAYNER 620 H. Rev Cubana Oftalmol [online]. 2008, vol.21, n.1. ISSN 0864-2176.

An important link in the advances made by the cataract surgery is the industrial development that has taken place in the last few years with the introduction of new intraocular lens models such as Rayner 620 H, the improvement of surgical implements, systems of bimanual aspiration and irrigation and custom-made scalpel to place the intraocular lens injector. IOL Rayner 620 H meant a step forward for phacoemulsification and the control of postoperative posterior capsule opacity due to the peculiar design of its optics and haptics that allows a safe and easy implantation using tiny incision. A prospective descriptive study was conducted in 28 eyes diagnosed with cataract, which underwent phacoemulsification with Rayner 620 H intraocular lens implantation performed at the Ocular Microsurgery Center of "Ramón Pando Ferrer" Cuban Institute of Ophthalmology from June 2006 to February 2007. The majority of patients was included in the over 60 years age group. All the cases showed a significant increase of visual acuity with and without correction from the preoperative to the postoperative phases. The keratometric cylinder also increased but slightly. Loss of endothelial cells was low from preoperative to postoperative phase. There was no complication during or after the surgery. We assessed the effectiveness of IOL Rayner 620 H as satisfactory because of the higher visual acuity of the patient, low induced astigmatism, improved visual field, minimal loss of endothelial cells and lack of complications and postoperative dazzling in the patients.
