摘要
The invention relates to medicine, in particular to ophtalmosurgery. The inventive method for an eye refractive surgery consists in delating the pupil by mydriatics, anaesthetising, and subsequently in incising the cornea. Afterwards, the anterior chamber is filled with a low-molecular-weight viscoelastic material and a refractive lens is implanted with the aid of a cannula which is connected to a source of vacuum ranging from 40 to 60 mm hg. For this purpose, said refractive lens is fixed to the midele between the lens edge and the boundary of the optical part thereof by means of the working cannula end and is bent thereon. Afterwards, the refractive lens is introduced into the cornea incision by the top of the bend and arranged in the posterior chamber of the eye. Vacuum is removed, the refractive lens being detached from the cannula and extracted from the anterior chamber of the eye. The inventive device for implanting the intraocular refractive lens comprises a cannula provided with a stop. Said cannula comprises a working funnel-shaped end face having an oval cross section, is connected to the body of a vacuum syringe and made of a low-pressure polyethylene or stainless steel, the working end thereof being coated with polyurethane methacrylate.
