Presented is the evaluation of the usefulness of the SRK formula for the calculation of the power of the intraocular anterior chamber lens of Pannu type. This accuracy is characterised by the value of the postoperative deviation of refraction of the operated eye. It has been noticed that the value of this deviation is fluctuating in the early postoperative period. Its stabilization comes out not before the 6th-9th month after surgery. This points out to the necessity of calculating the correcting coefficient A for the SRK formula into the late postoperative period.
