ABSTRACT:
An instrument and technique is disclosed for protection of lens posterior capsule of the eye during cataract operation. The instrument consists of a length of fine surgical wire mounted at one end in a tubular handle with the tip angled and coated with silicone rubber. The instrument is used in conjunction with the phaco-emulsification removal technique using an ultrasonic instrument, by positioning the coated tip of the instrument intermediate the posterior capsule and the cataract lens nucleus. The cataract lens nucleus is held away from the posterior capsule by manipulation of the instrument during the phaco-emulsification procedure, with the tip protecting the posterior capsule from the action of the ultra-sonic instrument.
