There was studied the role of the preoperative clinical data in development of surgically induced astigmatism in

76 patients with age-related cataract after the operation of US-phacoemulsification with implantation of the intraocular lens.

There was devised a mathematical model of prognosis of astigmatism development after the operation.

It is established that in cornea rigidity exceeding 0.3 mm Hg the risk of astigmatism development <1.0 Dpt less than in lower rigidity and makes 3.5 % in the incision of 2.2 mm and 17.0 % in the incision of 2.75mm.

To prevent high postoperative astigmatism development in low rigidity of the cornea in patients with age-related cataract it is necessary to use incisions of smaller size.
