Lenstar LS 900 is used for obtaining ocular measurements and performing calculations to assist in the determination of the appropriate power and type of IOL (intraocular lens) for implantation after removal of the natural crystalline lens following cataract removal. It provides the user with a complete biometrical assessment of the patient’s eye in a single measurement procedure, including lens thickness, anterior chamber depth (lens position) and retinal thickness.
