Abstract Details


Development and research of clinical efficiency of technique of long-term correction of aphakia when performing extraction of the age-related cataract through small cuts in eyes with the first degree of a lens subluxation.


The Khabarovsk branch of the State Institution Eye Microsurgery Complex named after S.N. Fyodorov, Khabarovsk, Russia


The short of the technique consists in carrying out a phacoemulsification through a corneal tunnel of 2.2 mm. Necessarily the iris retractors stabilize capsular bag. After excision of lens masses it is removed noninvasively and through a cartridge the IOL RSP-3 is implanted which is grafted to an iris by nylon 10-00. Two groups of patients with existence of 1 degree of the lens subluxation, comparable on age (on the average 73 years), sex, degree of cataract maturity were created. To all patients the phacoemulsification through a small corneal tunnel cut of 2.2 mm on the device Stellaris (Bausch&Lomb, the USA) was carried out. 30 eyes of 29 patients (the main group) were operated by this own technique. The group of comparison was made by 30 patients (30 eyes) – to whom implantation of intracapsular ring with the subsequent implantation of posterior chamber IOL (Aqua sense, Acrysof natural, Acreos MI-60, Rayner) into a capsular bag was carried out during a phacoemulsification. Criteria of comparison: correctness and stability of IOL situation, frequency of intra- and postoperational complications. Term of observation made 1.5-2 years.


In the general set of eyes all operations were performed per plan, without complications. For 1-2 days the correct IOL situation took place in all eyes of the main group (100%). In 2 eyes of the group of comparison there was an appreciable shift of the complex "capsular bag-intracapsular ring-IOL" in the vitreous cavity, demanded its excision through broad scleral access 5.0-5.5 mm, a forward vitrectomy and IOL RSP-3 implantation. 1.5-2 years later correctness and stability of IOL situation was defined in all eyes of the main group and in 24 eyes of group of comparison (80%). Vizometry indicators and the VGD level were correlative in both groups. Vizometry indicators made from 0,2 to 1,0 (on the average 0,69), the VGD level – on the average 19,8 mm hg.


The developed technique allows to achieve higher stability of IOL situation, with a minimum intra- and postoperational complications, and lack of clinically significant induced corneal astigmatism.
