METHOD OF TRANSSCLERAL INTRAOCULAR LENS FIXATION WITHOUT CAPSULAR SUPPORT Russian patent published in 2012 - IPC A61F9/07 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ophthalmology, and aims at surgical management of aphakia with complete or considerable absence of a posterior capsule of lens. A conjunctiva is separated; the 11 and 17 o'clock scleral valves 3×4 mm are cut out. A 10 o'clock paracentesis through which a viscoelastic is introduced in an anterior chamber is performed. Under one of the scleral flaps, tissues are perforated with a hollow guide needle. Then a cornea is perforated with a loop suture needle with a needle point placed in a hole of the guide needle. The hollow guide needle is moved back to be exteriorised with the looped suture arranged behind the iris. Then, tissues under the other scleral flap are perforated with the hollow guide needle, and the second looped suture is arranged behind the iris with similar manipulations. Through a 12 o'clock corneal incision 3.5 mm is made to exteriorise both loops with using tweezers. One of the loops is delivered though a first aperture of a haptic element of an IOL and thrown upon its free end, while the other loop is delivered though the second aperture of the haptic element and thrown upon its free end with fixing each haptic element of the lens in the coupled loop. The IOL is middled and implanted in an eye cavity, centred. Then, it is sutured through, and the suture ends are fixed under the scleral flaps.

EFFECT: method ensures reducing tissue injures, providing higher strength and reliability of the IOL fixation in an eye, minimising an IOL rotation risk in a sagittal plane, reducing length of manipulations for suture end fixation to the haptic elements of the IOL, ensuring high functional outcome.
