FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to ophthalmic surgery, and can be used to determine an axial position of a toric intraocular lens before implantation. A mark, which is an output point from scleral vessels on the eyeball surface, is found on a keratotopogram. A strong corneal axis is localised in relation to the above mark. That is followed by an intraoperative localisation of the strong corneal axis guided by the visualised mark. The presented corneal axis is marked. The toric intraocular lens is implanted which is guided by its working axis in relation to the mark and aligned with the marked strong corneal axis.
EFFECT: method provides the accurate corneal axis marking, and respectively ensures the accurate lens guiding when implanted for the optimum refraction effect of the operation.
